How to Build DIY Cornhole Boards

Creating your own cornhole boards brings the thrill of this classic lawn game right to your backyard. These portable, foldable platforms offer hours of entertainment at barbecues, tailgates, or casual hangouts. With basic woodworking tools and readily available lumber, anyone can assemble a regulation-compliant set that rivals store-bought versions. This guide outlines everything from material selection to custom finishes, ensuring your boards are sturdy, smooth, and ready for action.

Understanding Cornhole Basics

Cornhole, also known as bags or bean bag toss, involves two teams tossing 6×6-inch fabric bags filled with corn kernels toward elevated boards placed 27 feet apart. The goal is to score points by landing bags in the 6-inch central hole or on the board surface. A set consists of two identical boards, each 24×48 inches, raised at a 27-degree angle on the playing end. Building your own allows personalization while adhering to American Cornhole Association (ACA) standards for fair play.

Essential Materials and Tools

Gathering the right supplies upfront prevents mid-project trips to the store. Focus on quality plywood for a snag-free surface and pressure-treated lumber for weather resistance if storing outdoors.

• Playing Surface: Two sheets of ¾-inch plywood, each 24×48 inches
• Frame Lumber: Eight 2×4 studs (total 32 feet), cut into 48-inch lengths (four per board) and 21-inch ends (four per board)
• Legs: Four 2×4 pieces, each about 11-12 inches long, with one end angled at 25-27 degrees
• Hardware: 3-inch deck screws (box of 100), 4-inch ⅜-inch carriage bolts (four per board), matching nuts, lock nuts, and fender washers (eight each)
• Finishing: Wood glue, sandpaper (120-220 grit), paint/stain, polyurethane sealant

Tools Required:

• Circular saw or miter saw for straight cuts
• Jigsaw or 6-inch hole saw for the center hole
• Drill with ¾-inch spade bit, ⅜-inch bit, and pilot bits
• Tape measure, pencil, clamps, safety gear (glasses, ear protection)

Step-by-Step Construction Guide

Follow these precise steps to build two matching boards. Work on a flat surface and double-check measurements for symmetry.

1. Prepare the Frames

Cut four 48-inch 2x4s for the long sides and four 21-inch pieces for the short ends per board pair. Assemble each frame by positioning short pieces inside the longs, forming a rectangle. Pre-drill pilot holes to avoid splitting, then secure with 3-inch screws and wood glue. Ensure corners are square using a carpenter’s square.

2. Attach the Plywood Tops

Place the 24×48-inch plywood centered on each frame, allowing a 3-inch overhang on all sides for stability. Drive eight screws per board: three along each long side (one center, two 4 inches from ends) and one per short end. Glue underneath for extra hold. Sand edges smooth.

3. Cut the Iconic Hole

Mark the hole center: 12 inches from either side and 9 inches from the top edge. Use a 6-inch hole saw or drill a pilot with a ¾-inch bit then finish with a jigsaw. For tough plywood, opt for a corded drill and steady pressure. Clean burrs immediately.

4. Craft and Install Foldable Legs

Cut legs to 11 inches, miter one end at 25 degrees for the proper incline. Round the top pivot end with a jigsaw using a tape roll as a template, then sand smooth. Drill ⅜-inch holes 2 inches from the top. Bolt legs to the frame’s underside (positioned for 27-degree lift), using washers on both sides and lock nuts for secure, swiveling attachment.

5. Add Handles for Portability

On the short ends, cut 4×6-inch ovals or curves for handholds using a jigsaw. These make transporting the 27-foot setup effortless. Sand interiors to prevent splinters.

6. Sand and Prime

Smooth all surfaces with progressive grits up to 220 for bean bag glide. Wipe dust, then apply wood conditioner if staining.

Customization and Finishing Options

Elevate your boards from functional to fabulous with creative touches. A smooth, sealed surface ensures fair play and longevity.

For designs, trace stencils or logos with pencil transfer, then paint. Team colors or patterns make them party standouts. Seal with 2-3 polyurethane coats for weatherproofing.

Bean Bags and Game Setup

No boards complete without eight 6×6-inch duck canvas bags per set, filled to 1 pound with dried corn or resin pellets. Stitch double seams for durability. Set boards 27 feet apart (playing ends raised), toss from behind the opposite board. Score: 3 points in hole, 1 on board.

Safety and Maintenance Tips

• Store folded in a dry shed to prevent warping.
• Inspect hardware seasonally; tighten bolts.
• Use on level grass to avoid trips.
• Resand minor scratches for optimal slide.

Common Mistakes to Avoid

• Inaccurate Hole Placement: Measure twice from top edge.
• Weak Legs: Use carriage bolts, not screws.
• Rough Surface: Sand thoroughly; test with a bag.
• Non-Square Frames: Check diagonals match.

Advanced Upgrades

Add a scoreboard with cup holders using scrap 2x4s, or electronic sensors for auto-scoring. PVC pipe risers offer height adjustability for kids.

Frequently Asked Questions

What is the official cornhole board size?

Boards measure 24×48 inches with a 6-inch hole centered 9 inches from the top and 12 inches from sides.

How far apart do you place cornhole boards?

27 feet between the front edges of the raised ends.

Can I use pressure-treated wood?

Yes for frames, but not tops—opt for smooth plywood to avoid bag snags.

How long does building take?

4-6 hours for beginners, plus drying time.

What’s the best finish for outdoor use?

Polyurethane over stain or paint for UV and moisture protection.
