How long is a hurling pitch?

The Gaelic Athletic Association (GAA) is the governing body of the sport of hurling. For official match size sliotars (size 5 - men's), the circumference (measurement around) must be between 23-25 cm and weigh between 110-120 grams. The ribs, or outer seams must measure between 2.2-2.4 mm. The Camogie sliotar (size 4) is regulated in a similar way, with slightly smaller measurements in circumference, mass, and rib height.
