Cut the hole in the wrong spot or shrink the frame, and the boards play wrong forever — a bag that should drop cleanly clanks off the rim instead. The fix is measurement, not money. Every official spec for how to make custom cornhole boards comes down to four numbers: 48, 24, 6, and 9. Nail those, and the rest is finish work. Here’s the exact order to cut, assemble, and set up a regulation set, plus the mistakes that quietly ruin a build.
What Are The Official Cornhole Board Dimensions?
Anything smaller is a hobby board, and it plays like one.
The hole is the part most builders get wrong. Drill it 9 inches from the bottom instead and your boards will look fine and play badly.
- Length: 47 1/2 to 48 inches
- Width: 23 1/2 to 24 inches
- Hole diameter: 6 inches
- Hole center: 9 inches from the top edge, 12 inches from each side
- Material: smooth plywood, at least 1/2 inch thick
The American Cornhole Association’s sanctioned rules document is the source for all of those numbers, and it’s worth reading once before you buy lumber.
How Do You Cut And Assemble The Boards?
Cut one 24 by 48 inch top from smooth plywood at least 1/2 inch thick, drill the 6 inch hole on the measurements above, then frame and incline it so the front edge sits about 3 inches high and the rear about 12 inches.
Work in this order:
- Cut the top. Rip a 24 by 48 inch panel from 1/2 inch or thicker smooth plywood.
- Lay out the hole. Mark 9 inches down from the top edge, then split the 24 inch width in half for a center 12 inches from each side. Score the circle with a compass, then cut with a 6 inch hole saw or a router and jig. Cut from the playing side so any tear-out lands underneath.
- Build the frame. Box the underside with 1×4 or 1×3 stock so the top stays flat and the legs have something solid to bolt through. Keep the frame inside the 24 by 48 inch footprint.
- Attach the legs. Hinge a pair of legs at the rear so the top edge lifts to 12 inches and the front stays around 3 inches. That tilt is the whole game — the bag needs the ramp.
- Smooth the surface. Sand the top and round the inside lip of the hole slightly. Fill any voids or screw heads, then finish with a sanded sealer or paint and a light scuff between coats. The specs call for a smooth playing surface, and roughness eats bags.
What does it look like when the build is right? Set the board on a flat driveway, and a bag dropped straight down the middle should slide, not skip. If it hops, your plywood is too thin or your finish is too rough.
How Far Apart Do The Boards Go?
Adult play uses 27 feet between the front edge of one board and the front edge of the other. Kids throw from 12 to 15 feet.
Mark pitcher’s boxes on both sides of each board so players have a lane, and plan the whole court at 10 to 12 feet wide and 40 to 45 feet long. Playing indoors or under a carport?
Once the boards are set, the rules are simple.

Which Mistakes Ruin A DIY Cornhole Build?
Four errors account for nearly every bad homemade set: undersized boards, a misplaced hole, thin or rough plywood, and the wrong court distance. Each one changes how the game plays, not just how it looks.
| Mistake | What It Costs You | The Fix |
|---|---|---|
| Hobby-size top (smaller than 24 x 48) | Bags overfly and the board feels cramped | Cut to a full 24 by 48 inches |
| Hole measured from the bottom edge | Wrong landing zone, ugly play | Measure 9 inches from the top edge |
| 1/4 inch or rough plywood | Bounce, flex, and torn bags | Use smooth plywood at least 1/2 inch thick |
| Boards set 20 feet apart | Every throw comes up short | Set fronts 27 feet apart for adults |
| Flat or barely tilted top | Bags stop dead instead of sliding in | Raise the rear to 12 inches, front near 3 |
| Rough, unsanded finish | Bags wear out fast, throws grab | Sand and seal the playing surface |
| Indoor setup under a low ceiling | Arced throws hit the roof | Keep 12 feet of clearance overhead |
Get the footprint and the hole right, and you’ve built a set that plays like the ones in tournament racks. Everything else — paint, decals, cup holders — is decoration you can add later.
FAQs
What Size Plywood Do I Need For Regulation Boards?
A regulation top is 24 inches wide by 48 inches long, cut from smooth plywood at least 1/2 inch thick. A standard 2 by 4 foot panel gives you the top with a little trim waste, so buy one sheet per board and cut both from the same sheet if you want matched grain.
Can I Use 3/4 Inch Plywood Instead Of 1/2 Inch?
Yes. The specs set 1/2 inch as the minimum, so 3/4 inch plywood is legal and gives a stiffer, quieter board that resists bounce. The trade-off is weight — a 3/4 inch top makes each board noticeably heavier to carry, so weigh that against how often you move them.
Do The Boards Have To Be Exactly 27 Feet Apart?
For official adult play, yes — 27 feet from the front edge of one board to the front edge of the other. Shorter distances favor the thrower and change the game. Junior players throw from 12 to 15 feet, which is why backyard sets for kids often shorten the court.
