Bocce Court Size Calculator
Bocce court dims, area, and boards.
What it does
Bocce courts frame a long alley of skill: official 87 by 13 feet of crushed stone with foul lines 13 feet from each back wall. Backyard builds shrink to 60 by 10 without losing the game.
The tool above takes court type with count in feet or meters. It returns dimensions, area, and boards.
The default official court covers 1140 ft2 with 200 ft of boards. The metric mirror reads 26.5 by 4 m with 106 m2, and three backyard courts cover 1800 ft2.
Federation open rules set the official box with foul markings on surface and sides. Court design guidance repeats the regulation size with minimum and maximum backyard bands.
Surface decides speed more than size: oyster shell screams while clay grabs. Boards contain wild throws while foul lines police feet.
