Traditional cornhole boards are plywood, which means they swell when it rains, warp in the sun and have to be carried into the garage after every party. These are molded from UV stabilized resin, so you set them up once and leave them out.
Regulation spacing is 27 feet from the front edge of one board to the front edge of the other, with foul lines level with the front of each board. If your deck is tight, shortening to 20 or 21 feet is standard for casual and family play. Look for a level, non slip stretch of lawn or deck, and keep the throwing lane clear of walkways so nobody crosses through a game.
Cornhole pairs naturally with the rest of the resin outdoor games range including ping pong, ring toss, washers and lawn games.
