Build Your Own Cornhole Board DIY Guide

Understanding Cornhole Basics and Board Dimensions

Cornhole is a lawn game where players toss bean bags toward a wooden board with a hole cut into it. The game originated in the Midwest and has become increasingly popular at backyard gatherings, tailgates, and family events across the United States. Before building your own board, understanding the standard dimensions and gameplay will help you construct a functional, regulation-sized board.

Official cornhole boards measure 48 inches long by 24 inches wide and stand 12 inches high at the head of the board. The hole diameter is 6.25 inches, and it should be centered 9 inches from the top of the board and 12 inches from each side. The playing surface should be tilted at a 4-degree angle so the hole end is slightly elevated. These specifications matter because they affect gameplay balance and fairness. If your board is too flat, bean bags won't roll into the hole as easily. If it's tilted too steeply, the game becomes too difficult.

The board consists of a playing surface (typically plywood), a frame or legs for support, and the hole opening. Most DIY versions use 3/4-inch plywood for durability, though some builders use 1/2-inch plywood to reduce weight. The frame can be constructed from 2x4 lumber or 2x6 lumber, depending on how sturdy you want the final product to be. Understanding these basic components and measurements will guide your material selection and building process.

Practical Takeaway: Before purchasing materials, sketch out a simple diagram of your board with measurements labeled. This reference will keep you on track during construction and help you communicate with hardware store staff about material needs.

Selecting Materials and Tools for Construction

Building a cornhole board requires relatively modest material investments. For a standard board, you'll need one sheet of 3/4-inch plywood (4 feet by 8 feet), lumber for the frame (typically four 2x4s or 2x6s), wood screws (2.5-inch exterior-grade screws work well), wood glue, and sandpaper. The plywood serves as your playing surface, while the lumber creates the structural support system underneath. Exterior-grade materials are recommended if you plan to leave your board outside, as they resist moisture and weathering better than interior materials.

For the hole, you'll need a hole saw bit sized at 6.25 inches or slightly larger. Most hardware stores carry hole saw kits with multiple sizes. You can also use a jigsaw if you prefer, though a hole saw produces cleaner, more circular openings. Some builders add felt or a rubber rim around the hole edge to protect the wood and reduce splintering from repeated bag impacts. This optional material is inexpensive but increases durability significantly.

Essential tools for this project include a power drill (or hand drill), a circular saw or table saw for cutting plywood, a level to ensure proper tilting, a measuring tape, and a pencil for marking. A orbital sander helps smooth rough edges and the playing surface. A miter saw is useful if you're making precise cuts on the frame pieces. Many people have these tools already or can borrow them from friends and family. If you need to purchase tools, budget accordingly, as this may increase your total project cost.

The total material cost typically ranges from $50 to $150 depending on wood quality and whether you purchase tools. Using pressure-treated lumber and exterior plywood increases durability and cost. Pre-made cornhole boards from retailers often cost $150 to $400, making the DIY approach a reasonable value if you already have basic tools available.

Practical Takeaway: Create a complete materials and tools checklist before shopping. This prevents multiple store trips and helps you make substitutions based on what's available. Many hardware stores will make cuts for you at no charge, which can save time and equipment investment.

Cutting and Preparing Your Board Pieces

Once you have your materials, the first construction step is cutting your plywood to the correct size. From a standard 4-by-8-foot sheet, you'll cut two pieces measuring 48 inches by 24 inches. The most efficient way to do this is using a circular saw with a straight edge guide, though a table saw produces cleaner cuts. Mark your cutting lines clearly with a pencil and measure twice before cutting. If this feels intimidating, ask the hardware store to make these cuts when you purchase the plywood—most stores offer this service for a small fee or sometimes at no charge.

After cutting your plywood pieces, cut your lumber for the frame. You'll typically need four pieces of 2x4 lumber cut to 48 inches for the long sides and ends. If you're building a tilted board (which is standard), you may want one set of legs slightly shorter than the other. Some builders use a 2x6 for the front of the board and a 2x4 for the back to create the tilt naturally. Alternatively, you can use four equal-height legs and adjust the tilt during assembly using shims or by sanding the playing surface at an angle.

Once all pieces are cut to length, preparation involves sanding all edges and surfaces. Start with 80-grit sandpaper to remove rough spots and splinters, then progress to 120 or 150-grit sandpaper for a smoother finish. Pay special attention to the edges where the hole will be cut—smooth edges here prevent splinters and injuries when handling bags. Sand the entire playing surface so it's smooth but not slippery. A smooth surface allows bean bags to slide appropriately without excessive friction.

Before final assembly, drill the 6.25-inch hole in your first plywood sheet. Mark the center point (9 inches from the top, 12 inches from each side) with a pencil. Use the appropriate hole saw bit to drill from the top side of the board. Go slowly and let the tool do the work rather than forcing it. Once the hole is complete, sand the edges smooth with 120-grit or higher sandpaper.

Practical Takeaway: Save your second piece of plywood for later—some builders create a matching board as a pair, while others use it for alternate designs or repairs. Proper sanding at this stage prevents frustration during assembly and creates a safer final product.

Assembling the Frame and Base Structure

Frame assembly involves joining your cut lumber pieces into a rectangular box that will support the plywood playing surface. Lay out your four frame pieces on a flat surface in a rectangular arrangement. Before permanent assembly, use a level to ensure the surface is actually flat—this prevents wobbly boards later. If you're building a tilted board, you don't need a perfectly level surface at this stage, but you do need the pieces to be square and properly aligned.

Attach the frame pieces using 2.5-inch exterior-grade wood screws. Pre-drill holes slightly smaller than your screw diameter to prevent wood splitting. Drive two or three screws at each corner, spacing them so they don't interfere with each other. Wood glue applied at the joints strengthens the connection significantly and is highly recommended. Apply a thin bead of glue along the joint, then hold the pieces in place while driving screws. Wipe away excess glue with a damp cloth before it dries.

Once your rectangular frame is assembled, add legs or supports underneath. Many DIY builders use 2x4 lumber cut to approximately 12 inches to create legs at each corner. Others use longer pieces running the length of the board for more stability. The legs should be screwed securely to the underside of your frame, again using pre-drilled holes and glue. If you're building a tilted board, ensure the front legs are slightly shorter than the rear legs, or ensure the rear sits on a spacer to create the slight angle.

After the frame and legs are secured, attach your plywood playing surface to the top of the frame. Use 1.5-inch wood screws placed approximately every 12 inches around the perimeter and a few in the middle for support. Don't overtighten these screws, as too much pressure can warp the plywood. The plywood should sit flush with the frame on all sides. Check your measurements again—the hole should be exactly 9 inches from the head of the board and centered side-to-side.

Practical Takeaway: Take your time with this stage and don't skip the pre-drilling step. A solid
