Cornhole Court Calculator
Cornhole board spacing, deck, and hole specs.
What it does
Cornhole measures 27 feet between board fronts with a 2-by-4 deck and a 6-inch hole nine inches from the top. Juniors and social games shorten to 21 ft while keeping every board number identical. One distance sets the whole game.
The tool above prints regulation spacing, deck, and hole specs per level. Adults get 27 ft fronts with pitcher boxes 4 by 3 ft; juniors get 21 ft fronts. Courts run 8-10 ft wide across 40-45 ft of length.
The American Cornhole Association publishes each figure. Its rules page sets 27 ft fronts with junior 12-15 ft guidance, court widths, and cancellation scoring to 21, while its board page pins 23.5-24 by 47.5-48 inch decks with 6-inch holes. Historic mirrors preserve the 30-ft-from-hole foul line behind the 27.
Bags fly differently across 6 ft of gap. Junior distances suit kids and tight yards while keeping scoring identical: 3 in the hole, 1 on the board, cancellation to 21 or more. Level boards at regulation heights before first toss.
