Cornhole Court Setup: Official ACL and ACA Distance Rules for US Competitive and Backyard Play
Cornhole is one of the most popular outdoor lawn games in the United States, played at tailgates, backyard barbecues, family reunions, fundraisers, state fairs, and in organized competitive leagues across the country. The game involves tossing 15-to-16-ounce fabric bags filled with corn feed (or plastic pellets in modern bags) at a slanted wooden board with a 6-inch hole. A bag that goes through the hole scores 3 points, and a bag that lands and stays on the board scores 1 point. Teams cancel each other’s points at the end of each round (called “cancellation scoring”), and the first team to reach exactly 21 points wins the game under standard American Cornhole League (ACL) and American Cornhole Association (ACA) rules.
The official competitive distance for cornhole board placement, as established by the American Cornhole League (ACL), headquartered in Milford, Ohio, is 27 feet measured from the front edge of one board to the front edge of the opposite board. This means both boards are separated by a 27-foot gap between their front edges when set up for regulation ACL and ACA competitive play. With each board being 4 feet (48 inches) long, the total playing space from the back of one board to the back of the other is 27 feet plus 4 feet plus 4 feet, which equals 35 feet. On a standard residential backyard, this means you need a relatively clear, flat strip of about 10 to 12 feet wide and 36 to 40 feet long to set up a proper regulation cornhole court. The ACL at acl-sports.com is the primary organizing body for cornhole competitions across the United States and issues the official rulebook that governs ACL-sanctioned events nationwide.
How This Cornhole Distance Calculator Works for ACL Regulation and Family Recreation
This cornhole calculator covers five real-world US playing setups in one tool: official ACL and ACA 27-foot regulation distance for competitive and serious backyard players who want to practice at the standard tournament spec; 21-foot recreational adult distance used by millions of casual US players at tailgates and backyard parties where the full 27 feet either will not fit or feels too challenging for mixed-skill groups; 15-foot youth and junior distance for children under 12 who are learning the game; 20-foot senior and accessible distance for players who want a shorter game while maintaining a comfortable challenge; and a fully custom input for any specific backyard or venue situation you need to plan. For each mode, the calculator outputs the front-to-front board distance in both feet (the way US players talk about it) and inches (useful for measuring on the ground), a metric conversion for players using metric measuring tools, the total court footprint in feet, the board hole placement guide (9 inches from the top edge to the center of the 6-inch hole), the board tilt angle (approximately 10 degrees at standard ACL leg heights of 12 inches back and 3.5 inches front), and a top-down court diagram showing board position and pitcher’s boxes.

Cornhole Board Hole Placement, Tilt Angle and Pitcher’s Box Explained
The physical specifications of an ACL and ACA regulation cornhole board are as precise as the playing distance. Understanding the board specs matters for anyone building their own boards (a popular US DIY project), buying boards online, or setting up a tournament-grade court in a US park, community center, or event venue. The ACL regulation board must be exactly 24 inches wide and 48 inches long (2 feet by 4 feet). The playing surface is a smooth, painted wooden board (typically 1/2-inch to 3/4-inch plywood on a wooden frame) with a 6-inch diameter hole cut and finished in its center, positioned so the center of the hole is exactly 9 inches from the top end of the board (the end facing the opposing player) and centered 12 inches from each side edge. The hole must be cut clean with no burrs or rough edges that could affect bag entry or damage bags during play.
The board must be elevated at an angle to create the playing surface tilt: the back edge (closest to the thrower) sits 12 inches from the ground, while the front edge (facing the opposing board) sits 3.5 to 4 inches from the ground. At the standard height of 12 inches back and 3.5 inches front, the rise is 8.5 inches over a 48-inch run, producing a tilt angle of approximately 10 degrees. This tilt is critical for gameplay: too flat and bags slide off easily, too steep and bags that touch the board face tend to bounce rather than stick. Most commercially available US cornhole sets achieve this tilt through folding metal or wooden leg assemblies that lock at the correct height. When buying US cornhole sets, look for sets labeled “ACL approved” or “regulation size” for guaranteed compliance with official specs.

Pitcher’s Box and Player Positioning in US Cornhole
One aspect of cornhole setup that confuses many new US players is player positioning. In cornhole, you do not stand behind your own board to throw. Instead, each player stands in the “pitcher’s box,” an unmarked but agreed-upon zone beside their own board, parallel to it. The pitcher’s box extends along the length of the board from its front edge to its back edge, and extends 3 feet to each side of the board’s side edges. Players throw from anywhere within this 3-by-4-foot zone beside their own board, aiming toward the opposite board 21 to 27 feet away. This means in a standard two-team (two-player-per-team) cornhole match, both players on a team stand in their respective pitcher’s boxes beside the same board at the same end of the court, while the two opposing players stand at the far board. Rounds alternate: Team A throws all four bags from their end, then Team B throws all four bags from their end, and cancellation scoring is applied after each complete round.
ACL vs ACA vs Recreational: US Cornhole Distance Standards Compared
The American Cornhole League (ACL) and the American Cornhole Association (ACA) are the two primary organizing bodies for competitive cornhole in the United States, and both use the identical 27-foot regulation distance for official competition. The ACL, founded in 2015 and headquartered in Milford, Ohio, is the newer and currently larger organization by member count, with a nationwide network of ACL-affiliated local events, a professional tour with prize money, and a popular presence on social media platforms. The ACA, the older organization, was founded in 2005 and helped standardize the game’s rules across the US. While the two organizations compete for the title of “official” US cornhole governing body, their equipment and court specifications are effectively identical, which means sets approved by one body are playable at the other’s events without modification.
For recreational US players who are not competing in organized league play, the most common backyard distance used at US tailgates, barbecues, and family parties is 21 feet rather than the official 27. The 6-foot reduction from regulation brings the boards close enough for casual players to score regularly, keeping the game fun for mixed-skill groups where some players are experienced and some are first-timers. At 27 feet, players who have never thrown before often cannot even reach the opposing board with their first several tosses, which kills the fun at informal gatherings. The 21-foot recreational standard has become widespread enough in the US that many bags and board sets sold at Walmart, Target, and sporting goods chains include markings or instructions for both 27-foot and 21-foot setups.
Scoring, Cancellation Rules, and What Counts in US Cornhole
In standard ACL and ACA scoring, a bag that falls through the 6-inch hole scores 3 points, a bag that lands and stays on the board’s playing surface without touching the ground first scores 1 point, and a bag that hits the ground before landing on the board does not count even if it bounces onto the board. At the end of each round (after both teams have thrown all four of their bags), cancellation scoring is applied: the team with the higher round score subtracts the opposing team’s round score, and only the difference counts toward the game total. For example, if Team A scores 9 (three bags on board) and Team B scores 6 (two bags on board), Team A nets 3 points for that round. Team B nets zero. The first team to reach exactly 21 points wins, and if a team goes over 21 their score reverts to 13 (a rule called “bust” in many US variants, though the ACL’s official rules simply require reaching 21 exactly without busting). Bags may be knocked off the board by subsequent throws from either team, so strategy around positioning bags and knocking opponents’ bags off the board is a key part of higher-level US cornhole play.
01
Mark Your Court Before Play for Consistent Distance Every Time
If you are setting up a cornhole court regularly in the same backyard or driveway, the single most valuable thing you can do is permanently mark the board placement positions on the playing surface. For a concrete driveway or patio, chalk or washable paint marks at the four corners of each board’s footprint take 2 minutes to apply and mean you can set up in under 60 seconds every time without measuring. On grass, use landscape flags or small spray-paint marks at the front corners of each board. Even a few inches off from true 27 feet (or your preferred recreational distance) consistently changes the feel of the game and makes practice at home less applicable to tournament play. For US players planning to compete in ACL or ACA events, practicing at the exact 27-foot regulation distance is essential: the difference between 21-foot recreational and 27-foot competition play is significant, and players who train at shorter distances often struggle when first competing at full distance. Use this calculator to generate your exact setup measurements, print the PDF, and keep it on hand for event setup.
02
Use the Front-Edge Measurement, Not Center-to-Center or Hole-to-Hole
The official ACL and ACA board-to-board distance is always measured from the front edge of one board to the front edge of the other board. This is the most common source of setup error in the US: players measuring hole-to-hole, center-to-center, or back-edge-to-back-edge all get different numbers and none are the correct specification. At 27-foot regulation, front-edge to front-edge is 324 inches. Hole-to-hole (from the near edge of one hole to the far edge of the other) is a different number that varies with exact hole positioning. Back-edge to back-edge at 27 feet of front-edge distance would be 324 plus 48 plus 48 equals 420 inches (35 feet). Always use front edge to front edge as your measurement starting point, since this is what ACL and ACA rules specify and what all tournament setup teams use. This calculator displays and labels all measurements clearly to avoid this common confusion, and the top-down court diagram visually shows the front-edge reference points.
03
Play on Level Ground and Check Board Level Before Starting
One factor that dramatically affects cornhole gameplay quality that many US players overlook is ground level. Grass lawns, especially in the Midwest and South where cornhole is most popular, often have gentle slopes, dips, or crowns that can cause a board to sit unevenly on the ground. When one side of a board is 0.5 to 1 inch lower than the other side, bags thrown toward the lower side of the hole have a different entry angle than bags thrown toward the higher side, creating an unfair asymmetry that favors certain throwing positions over others. Before serious play, use a simple bubble level (a 2-foot level from any US hardware store) to check both the left-right tilt and the front-back tilt of each board. Front-back tilt should be at the standard 10-degree board angle from the folding legs. Left-right tilt should be as close to zero (perfectly level side to side) as possible. Use rubber shims, wooden wedges, or even cardboard folded thick enough to level boards on uneven grass. For ACL sanctioned events, tournament directors check board level before play and adjust as needed. For home play, 5 minutes of leveling before a backyard tournament makes the game fair and more fun for all players.
Cornhole Distance Questions US Players and Tournament Directors Ask Most
The official American Cornhole League (ACL) and American Cornhole Association (ACA) regulation distance is 27 feet, measured from the front edge of one board to the front edge of the opposite board. In inches, this is 324 inches (324 / 12 = 27 feet). In metric, this is 8.2296 meters (27 feet times 0.3048 meters per foot). This 27-foot distance is used in all ACL-sanctioned tournaments, regional competitions, and professional cornhole events across the United States. It is also the distance recommended for any US player who wants to practice for competitive cornhole play. Some older publications and community leagues in the US have used different distances ranging from 24 to 30 feet, but 27 feet is the accepted current standard for organized play. This calculator uses 27 feet as its ACL and ACA Regulation mode default.
Measure cornhole board distance from the front edge of one board to the front edge of the other board. The front edge is the lower end of the slanted board, closest to your opponent. Place both boards in their playing positions, measure from the front edge of Board 1 to the front edge of Board 2, and adjust until the measurement is exactly 27 feet (324 inches) for regulation play, or your chosen recreational distance. Do not measure hole-to-hole, center-to-center, or back-edge-to-back-edge, as all three give different numbers that are not the correct ACL or ACA specification. A standard 25-foot or 35-foot tape measure from any US hardware store works perfectly. If you are setting up a court on grass, use two tent stakes or ground markers at the front corners of each board to maintain position throughout the game, as boards can shift on soft ground during play. This calculator outputs front-edge-to-front-edge distance in feet, inches, and metric, making field measurements straightforward.
For children under 12, a playing distance of 15 feet (180 inches) is generally recommended as a starting point. At this distance, children aged 6 to 10 can reach the board with a moderate toss and begin developing the arm swing and release timing that cornhole requires. Children aged 10 to 12 may be comfortable at 18 to 20 feet depending on their arm strength and experience. There is no single official ACL or ACA junior distance standard: most US youth cornhole programs and family play simply agree on a shorter distance that gives the youngest players a reasonable chance to score. Many US families use this progression: under 8 years old at 10 to 12 feet, 8 to 10 years at 15 feet, 10 to 12 years at 18 to 20 feet, and 12 and older at full 21-foot recreational or 27-foot regulation depending on skill level. As children improve, gradually increasing the distance toward 27 feet trains them for competitive play. Lower the front edge of the board slightly (2 to 3 inches instead of 3.5 inches) for very young children to reduce the effective throwing angle and make bag retention on the board easier.
The ACL and ACA regulation cornhole board is 24 inches wide and 48 inches long (2 feet by 4 feet). The playing surface is smooth and must be solid, with no warping or visible defects. The 6-inch diameter hole is centered at 12 inches from each side edge and 9 inches from the top edge (the end that faces the opposing player). The top edge is the far end of the board from the thrower’s perspective, and the hole center at 9 inches from this edge means the hole’s near edge is approximately 6 inches from the top of the board. This puts the hole well toward the top of the board, which is correct for ACL play. Boards are typically made from 1/2-inch to 3/4-inch Baltic birch plywood or sanded pine plywood on a painted or finished wooden frame. The surface must be painted or finished to a consistent texture: boards that are too rough cause bags to stick unpredictably, and boards that are too slick cause bags to slide off. Most commercially sold US regulation cornhole sets from brands including GoSports, Gosports, Franklin Sports, and EastPoint Sports meet ACL spec when labeled “regulation size.”
ACL and ACA regulation cornhole boards have a back edge (the end closest to the throwing player) at 12 inches from the ground and a front edge at 3.5 to 4 inches from the ground. This height difference over the 48-inch board length creates a tilt of approximately 10 degrees, which is the standard ACL playing angle. At this tilt, bags thrown onto the board surface at a gentle arc tend to slide toward the hole area and bags with too much velocity tend to slide off the top. Most folding-leg cornhole boards sold in the US achieve the correct back height of 12 inches automatically when the legs are fully deployed. If your set uses adjustable legs, set the back legs to 12 inches and the front legs to 3.5 to 4 inches. Some US players prefer a slightly steeper tilt (front edge at 3 inches) in wet or dewy grass conditions to help bags reach the hole area without sticking to a damp surface, and others prefer a 4-inch front height in hot, dry conditions to help bags stay on the board more easily. The ACL allows minor variation in front edge height between 3 and 4 inches, with 3.5 inches being the most common specification.
In cornhole, players stand in the pitcher’s box beside their own board, not behind it. The pitcher’s box is an imaginary zone that extends alongside the board, from the front edge to the back edge of the board’s 48-inch length, and approximately 36 inches (3 feet) to each side of the board’s side edge. Both players on the same team stand in the pitcher’s boxes on the same side of the court (one player on each side of the same board), throwing toward the far board. At the 27-foot regulation distance, you are throwing at the opposite board that is 27 feet away as measured from the front of your board to the front of their board. You must release the bag from within the pitcher’s box and may not step past the front edge of your own board when throwing. This player positioning means that two players from opposing teams can simultaneously throw from the same end of the court if they are in the pitcher’s boxes on opposite sides of the same board: Team A’s player 1 and Team B’s player 2 both stand at one end, while Team A’s player 2 and Team B’s player 1 stand at the other end.
Cancellation scoring is the official ACL and ACA method for calculating round scores in cornhole. After both players on a team have thrown all four of their bags in a round (a full round consists of eight total bag throws), each team counts their points for that round (3 per hole, 1 per bag on board), and then the lower score is subtracted from the higher score. Only the net difference counts toward the game total. For example, Team A: two bags in hole (6 points) plus one bag on board (1 point) equals 7 points. Team B: one bag in hole (3 points) plus two bags on board (2 points) equals 5 points. Net: Team A gets 7 minus 5 equals 2 points for the round. Team B gets zero. This cancellation system means neither team builds points quickly in evenly matched games, and big lead changes can happen when one team has a breakout round. The first team to reach exactly 21 points wins. Under ACL rules, you must hit exactly 21: a round that would put you over 21 does not bust you back but also does not push you past 21 unless you can get exactly to 21 in subsequent rounds. Some local US leagues play “bust” rules where going over 21 drops your score to a set number like 13 or 15.
Yes, but a sloped lawn affects gameplay and should be accounted for in setup. The primary concern is board level: each board should sit as level as possible from side to side (left-right) when viewed from the throwing position, even if the lawn slopes gently from end to end (the direction of throwing). A slight slope in the direction of throw (one board slightly uphill from the other) changes the throwing arc needed to reach each board and is generally accepted in casual backyard play, though serious ACL practice should be on level ground. A significant side-to-side lean of a board (one side higher than the other by more than 1 inch) creates unfair throwing conditions and should be corrected by placing shims under the lower side of the board. US players commonly use pieces of rubber door mat, folded cardboard, or thin pieces of wood as field-expedient shims under low corners of cornhole boards on uneven grass. For tournament setup in parks and outdoor venues, ACL event organizers typically select the flattest available area and place boards on designated rubber mat pads that keep the boards level and stable on grass. This calculator assumes flat playing surface in all of its court footprint calculations.
The American Cornhole League (ACL) and American Cornhole Association (ACA) have very similar rules for competitive play, using the same board dimensions, hole specifications, and 27-foot playing distance. The primary differences are organizational rather than gameplay-related. The ACL is generally more active in professional and semi-professional competitive cornhole events, has built a more visible media presence including streaming on ESPN and ESPN2, and runs a professional tour with prize money and world rankings. The ACA focuses more on grassroots and community-level organized cornhole and has been active since 2005, predating the ACL. Both organizations approve bags and boards for official competition, and their equipment specifications are effectively identical. For a US player setting up a backyard court, both organizations’ rules produce the same setup: 27 feet front to front, standard board dimensions and hole placement. If you plan to enter local competitive cornhole events in the US, check whether your region’s events are ACL-affiliated or ACA-affiliated (or both) and register accordingly. The ACL’s website at acl-sports.com has a national event calendar and a directory of ACL-affiliated local leagues across the US.
Under ACL and ACA official rules, a bag that lands on the board and then falls off (either from the board sliding, from being knocked off by a subsequent throw, or from initially landing and then rolling off) does not count for points. Only bags that are still on the board’s playing surface, or bags that passed through the hole, count at scoring time. If a bag bounces off the ground and then lands on the board, it does not count (ground first is not a valid landing). Bags knocked off the board by a player’s own team count as zero for that player’s turn (no penalty). Bags knocked off the board by an opposing team’s throw that were already on the board also no longer count: only bags in their final position at scoring time are counted. Any bag that is touching the ground (even if partially on the board) is considered off the board and scores zero. These rules are consistent between ACL and ACA. In informal US backyard play, many groups use a more relaxed rule where a bag that originally lands on the board is counted even if it is later knocked off: this is a common house rule but is not official ACL or ACA scoring.
ACL regulation cornhole bags must weigh between 15 and 16 ounces and be 6 inches by 6 inches square (some bags are slightly oversized at 6.25 inches on a side, which is also ACL-legal). Bags come in two main constructions for US players: all-fabric bags (typically duck canvas or synthetic fabric) and dual-sided bags (one side with a stick fabric for more grip and one side with a slick fabric for more slide). Dual-sided bags are the dominant choice among competitive US cornhole players because they allow strategic selection of which side to throw: the stick side keeps bags on the board and is preferred for landing bags that stay put, while the slick side allows bags to slide toward the hole from across the board surface. Major US cornhole bag brands include Grip-N-Rip (widely used in ACL professional competition), Dead Nuts (popular at the competitive level), Wild Hare (popular US brand), and Airmail (premium competition bags). For casual backyard play, almost any 15-to-16-ounce bag works fine. Budget sets from US retailers like Walmart’s GoSports brand or Target’s Kan Jam line include eight bags (four per team) at a price point of 25 to 60 dollars for a complete set including boards. Serious ACL competitors often spend 50 to 150 dollars per set of four bags on premium dual-sided competition bags.
For a regulation ACL and ACA 27-foot cornhole court, you need a minimum of approximately 8 to 10 feet of width and 36 to 40 feet of depth. The 8 to 10-foot width allows for a 2-foot board on each side plus 2 to 3 feet of pitcher’s box space beside each board for the throwing player to stand. The 36 to 40-foot depth accounts for the 27-foot board-to-board distance plus 4 feet per board length plus a few feet of clearance behind each board for players standing in the pitcher’s box at each end and for bags that go long. In practice, a standard US suburban backyard patio or side yard of 10 feet by 40 feet easily accommodates a regulation court. If space is tight, the recreational 21-foot distance reduces the total court depth to approximately 29 to 33 feet. For very tight spaces, the 15-foot youth distance requires only about 23 to 27 feet of depth. This calculator outputs the total court footprint for each mode, helping you determine whether your specific yard or venue space can fit your desired playing distance. Measurements from this calculator include both board lengths in the total depth figure.
Yes, cornhole boards can be used on concrete driveways, asphalt parking lots, patios, and other hard surface areas, which are actually popular venues for cornhole in the US because they provide a flat, stable surface that keeps boards exactly where you set them without shifting. The main consideration on hard surfaces is that the rubber or plastic feet on most cornhole board leg assemblies can slide on smooth concrete if players are stepping around aggressively or if the boards take an impact from a hard-thrown bag. Use non-slip furniture pads or rubber mat pieces under the feet of each board leg to prevent sliding on concrete or tile. Also, be aware that bags that miss the board and hit concrete directly will wear out faster than bags that land in grass, because the abrasive hard surface scuffs the fabric finish, particularly on slick-side synthetic bags used by competitive players. Tournament organizers in the US who use parking lots or concrete floors for indoor events typically place rubber mats or carpet pads under the boards to protect the board feet and provide a small amount of shock absorption. This calculator’s court footprint measurements apply equally to hard surface and grass setups.
Building DIY cornhole boards is an extremely popular project among US woodworkers and sports enthusiasts, partly because custom boards allow personalized paint designs and fan art, and partly because quality DIY boards can be made for 30 to 60 dollars versus 80 to 200 dollars for premium commercial sets. To build ACL regulation boards you need: one 4-foot by 8-foot sheet of 1/2-inch Baltic birch or cabinet-grade plywood (cut in half to get two 24-inch by 48-inch boards), 2×4 lumber for the frame (two side rails per board at 48 inches, two end rails at 21 inches to account for the 2×4 thickness), a 6-inch hole saw or jig saw to cut the hole, wood screws, sandpaper, wood filler for the hole edge, folding metal legs or fixed wooden leg assemblies, and exterior paint or a polyurethane finish for weather protection. Cut the hole center at 9 inches from the top end of the board, centered at 12 inches from each side. After cutting, sand the hole smooth with 220-grit paper or a drum sander attachment and fill any voids with wood filler before painting. Popular US YouTube channels including DIY Daddy and Family Handyman have free cornhole board building tutorials. The ACL website at acl-sports.com has a full board construction specification document for US players who want to build to exact regulation standards.
A standard ACL regulation cornhole board sits at approximately 10 degrees of tilt when set up with the back edge at 12 inches from the ground and the front edge at 3.5 inches from the ground. The exact angle calculation is the arctangent of the rise (12 minus 3.5 equals 8.5 inches) divided by the run (48 inches), which equals arctangent of 0.1771, which equals 10.04 degrees. This 10-degree slope is a fundamental design element of cornhole: it creates a surface steep enough that bags thrown at the board’s upper section will naturally slide or roll toward the hole area under their own momentum, while bags thrown with too much force or too low a trajectory will slide off the front edge before stopping. This is the mechanical basis for cornhole strategy around throw arc and force. Some US players who prefer a more challenging game slightly increase the front edge height to 4 inches, reducing the tilt to approximately 9.5 degrees. Boards tilted too steeply (front edge below 3 inches) make it harder for bags to stay on the board without sliding off even at moderate landing speeds. This calculator shows the tilt angle as part of its board specifications output and can optionally display this information when the tilt angle toggle is enabled.
The ACL does not mandate a specific outdoor surface type for recreational or even competitive cornhole, as the game is fundamentally an outdoor tailgate sport designed to be played on whatever surface is available. However, ACL-sanctioned tournament organizers typically prefer and seek out level, closely mowed grass (which is the traditional US setting for the game), level asphalt or concrete in parking lots, or indoor gymnasium or convention hall floors for large events. Each surface has gameplay effects: freshly mowed level grass gives bag play that closely matches what boards are designed for, with a slight natural resistance to sliding if a bag misses the board. Concrete and smooth indoor surfaces produce more bag bounce when bags miss the board (those bags do not count even if they bounce onto the board), which increases the advantage for accurate throwers. Wet grass can make boards slippery and affect bag landing behavior significantly, which is why tournament directors sometimes delay outdoor ACL events in rain. For backyard play, a flat lawn in good condition is ideal. Avoid playing on soft, muddy ground that can cause boards to sink and become un-level during play. The ACL event rulebook, available at acl-sports.com, has provisions for what to do when weather or surface conditions affect tournament play.
Cornhole board distance and specification data in this calculator is based on published American Cornhole League (ACL) and American Cornhole Association (ACA) rulebooks and official specification documents. The regulation 27-foot board-to-board distance, board dimensions (24″ x 48″), hole specifications (6″ diameter, 9″ from top), and board height specifications (12″ back edge, 3.5″ front edge) are derived from ACL official rules available at acl-sports.com. Recreational, youth, senior, and custom distance modes are provided as general-purpose guides for non-competitive US recreational play and do not represent any official ACL or ACA standard. Board tilt angle is calculated mathematically from standard ACL height specs and is approximate; actual board tilt may vary with leg adjustment and surface conditions. Total court footprint calculations add board length to each side of the playing distance and are planning estimates only. USCalculators.com has no commercial affiliation with the American Cornhole League, the American Cornhole Association, or any cornhole bag or board manufacturer mentioned in this guide. Always verify your court setup against current ACL and ACA official rules before sanctioned competition, as specifications may be updated. Calculator outputs are for planning purposes; always measure on site before permanent court marking.
