Difficulty Level	Beginner-Friendly

Building your own DIY cornhole boards is one of the most satisfying weekend projects a beginner woodworker can tackle — regulation-size boards that would cost $150–$200 at retail, built for under $90, in an afternoon.

There is something profoundly satisfying about the convergence of precision and play — about the idea that the same skills, the same tools, and the same respect for material that go into a dining table or a workbench can also go into building a set of cornhole boards that will anchor a hundred backyard gatherings over the next decade.

This guide builds to the official American Cornhole Association (ACA) regulation specifications. Whether you’re building for casual backyard use or for genuine competition play, building to regulation ensures the game plays correctly and that your boards will be welcome at any organised event. Let’s get into the build.

ACA regulation dimensions

Building to official specifications matters even for casual play. Regulation dimensions ensure the game plays as intended, the physics of the bag toss work correctly, and your boards are welcome at any organised event or tournament.

The shopping list

Everything on this list is available at your local big-box home centre. No specialty lumber required.

Step 1 — Cut the playing surfaces

Cut your 3/4″ ACX plywood to the regulation 24″ × 48″ dimensions. Use a circular saw with a straightedge guide clamped to the panel to ensure perfectly straight cuts. The smooth face of the ACX plywood should face upward — this is your playing surface, and it needs to be as flat and blemish-free as possible.

Mark and drill the 6-inch hole centre point now (9 inches from the top edge, 12 inches from each side), but don’t cut the hole yet — wait until after the frame is assembled and the surface is attached, so the frame supports the panel during the cut.

The choice of ACX plywood is deliberate and worth understanding. The “A” face designation means it has been sanded smooth and is free of open knots and major defects — exactly the quality you need for a clean paint job.

The “C” back face is rougher and is the underside, hidden by the frame. Using a lower grade of plywood on the playing surface — CDX construction sheathing, for example — will result in a rough, porous surface that soaks up paint unevenly and looks amateurish no matter how carefully you apply it.

Spend the extra few dollars per sheet on ACX and the painted finish will look genuinely professional.

Step 2 — Build the frames

Drill two pocket holes into both ends of each short (21-inch) rail using your pocket hole jig set for 1½-inch thick stock. Apply a bead of waterproof wood glue to the end of each short rail, clamp it flush with the end of the long rail, and drive your 2½-inch pocket hole screws to lock the joint.

The resulting rectangular frame should measure exactly 24 inches × 48 inches on its outer dimensions. Check for square by measuring diagonally from corner to corner — if both diagonal measurements are equal, the frame is perfectly square. Let the glue cure for at least 30 minutes before moving on.

The structural logic of the frame is straightforward, but worth understanding. The playing surface of a cornhole board takes a significant and repetitive dynamic load — the impact of bags thrown from 27 feet away, multiplied over hundreds of throws per game, multiplied over hundreds of games over the life of the board. The frame is not decorative; it is the structural spine that prevents the plywood surface from flexing, cracking, or delaminating under this cyclical loading.

The pocket-hole-and-glue joint provides both the mechanical clamping during the cure and, once the PVA bond is set, the shear strength to resist the racking forces that each bag impact generates.

Step 3 — Attach the playing surface

Place the plywood playing surface (smooth face down, for now) on a flat surface. Position the assembled frame on top of it, centred perfectly. Drive 1¼-inch exterior screws through the frame rails into the plywood every 8 inches, working from the centre outward to avoid any bowing.

Add a thin bead of wood glue along the top face of each rail before setting the plywood — this glue bond, combined with the mechanical fasteners, is what makes the surface rigid and prevents the characteristic hollow “thwack” sound of a loosely attached playing surface.

Step 4 — Cut the regulation hole

Flip the assembled board over so the smooth playing surface faces up. Mark your hole centre at 9 inches from the top edge and 12 inches from each side edge. Use a compass or a simple trammel (a strip of wood with a nail at one end and a pencil hole 3 inches out, to scribe a 6-inch diameter circle) to mark the cut line precisely.

Drill a starter hole just inside the circle line using a large spade bit or Forstner bit — this gives your jigsaw blade an entry point. Cut the circle with your jigsaw, keeping the blade just inside the line. Sand the cut edge smooth and apply a coat of exterior primer to seal the end grain of the plywood, which would otherwise absorb moisture and swell, causing the hole edge to chip and deteriorate.

The precision of the hole cut matters more than it might seem. The ACA specifies 6 inches exactly because the regulation cornhole bag measures approximately 6 inches × 6 inches and weighs 15–16 ounces. A hole cut to 5½ inches will reject bags that should score; a hole cut to 6½ inches will accept bags that grazed the edge.

The 3-point score depends entirely on the bag passing cleanly through the hole, and a hole that is too small or too large fundamentally changes the game’s physics and fairness.

Step 5 — Build and attach the legs

Cut your rear legs to 12 inches and your front legs to 3½ inches. The height differential between rear and front leg creates the regulation pitch angle. Attach the rear legs to the back corners of the frame using glue and 2½-inch exterior screws, angling them slightly outward (approximately 10 degrees) for stability.

Attach the shorter front legs at the front corners in the same manner. If you want the boards to be portable and stackable, use folding leg hardware — bolt-on hinges that let the legs fold flat for transport. This is strongly recommended if you plan to take the boards to events rather than leaving them permanently in the backyard.

Step 6 — Sand, prime, and finish

Sand the entire playing surface thoroughly with 120-grit followed by 220-grit. Pay particular attention to the hole edge and any plywood end grain exposed at the board’s perimeter — these areas absorb paint unevenly if not properly sealed.

Apply two coats of exterior primer, allowing full drying time between coats. Paint your design using exterior latex paint — the ACA allows any design you like, as long as the board dimensions and hole position are correct.

Once the paint has fully cured (allow 24-48 hours minimum, longer in cold or humid conditions), apply two to three coats of exterior spar urethane over the entire playing surface.

The finishing protocol matters more here than on most furniture projects because cornhole boards live outside year-round in most households — baking in summer sun, sitting under autumn rain, potentially freezing in winter.

Exterior latex paint is flexible and adheres well to primed plywood. The spar urethane topcoat adds UV resistance (preventing the colours from fading) and a hard, slick playing surface that allows bags to slide naturally toward the hole rather than grabbing on a rough painted surface. Do not skip the topcoat — painted cornhole boards without a urethane seal typically show significant wear within a single season.

The heritage touch

Before you reach for the paint roller, consider giving the playing surface one pass with a well-tuned hand plane or a cabinet scraper. The ACX plywood surface, while sanded at the factory, often still carries subtle mill marks and slight variations in thickness that will telegraph through paint.

A few careful passes with a sharp #4 smoothing plane — set for a gossamer-thin shaving, held at a slight skew — will leave a surface so flat and burnished that the paint will lay down with the evenness of a sprayed finish. It takes ten minutes and makes the difference between a board that looks handmade and a board that looks crafted.
