What Are Cornhole Boards? | Regulation Dimensions And Rules

If you’re here because you’ve seen them at tailgates or backyard cookouts and wondered what makes a “real” set, here’s the short version: cornhole boards are two identical sloped platforms that players throw bean bags at, trying to land bags on top or drop them through the hole. While casual sets come in all shapes and sizes, official rules define exact dimensions for the board itself, the hole placement, and the surface finish. Knowing these details matters whether you’re building a set, buying one, or just settling an argument at a party.

The Core Purpose Of Cornhole Boards

Cornhole boards are the standardized playing surfaces for the game of cornhole. Each board sits at an angle—the front edge is 3 to 4 inches off the ground while the back edge rises to 12 inches—creating the slope that makes bag placement and hole drops challenging. The surface is designed for bags to slide slightly but not so freely that they glide back down the incline. A properly made board gives consistent play, so skill, not surface luck, decides the winner. That’s why official rules insist on smooth plywood rather than plastic or other materials, which play noticeably differently.

Regulation Size And Dimensions That Actually Matter

Regulation cornhole boards follow a strict footprint. The playing surface measures 47 1/2 to 48 inches long and 23 1/2 to 24 inches wide, made from smooth plywood at least 1/2-inch thick. The hole is 6 inches in diameter (plus or minus a 1/4-inch tolerance), centered 9 inches from the top edge and 12 inches from each side. The board sits with the front edge 3 to 4 inches high and the back edge 12 inches high, resting on a wood frame. The surface must be sanded very smooth, free of blemishes, and free of any added powders, sprays, or other substances that alter slide. Think of the finish as “slick but grippy”—bags should slide into the hole, not skate off the back or stick where they land.

What You Need To Know About Playing On Them

Official rules set the adult pitching distance at 27 feet between the front edges of the two boards. Junior players 12 and under can use a shorter distance of 12 to 15 feet, which keeps the game fun while kids build their throwing skills. Courts typically need about 40 to 45 feet of length and 10 feet of width to accommodate the boards, the pitch, and room for players to step back. When it comes to buying a set, the single biggest mistake people make is grabbing boards cut from standard 2×4 lumber dimensions—those aren’t regulation-sized. The second most common error is a misdrilled hole that sits too close to the edge or off-center. For a compliant set, match the 48 x 24-inch footprint and the centered 6-inch hole at 9 inches from the top. If you’re weighing options for a backyard set, our roundup of the best cornhole boards for home use breaks down the top available choices including regulation-compliant options.

The American Cornhole Organization’s official rules spell out the wood-surface requirement clearly: the board must be smooth plywood with a wood frame, and the surface must not be treated with foreign substances like talc, resin, spray, or powders. These rules exist because non-wood surfaces—plastic, metal, or coated composites—change how bags slide and bounce. While casual backyard play doesn’t require tournament compliance, a set that follows these specs will play more predictably.
