Okay let's be honest – buying a cornhole set costs way more than it should. I learned that the hard way when I dropped $300 on a fancy set that broke after one season. Turns out, learning how to make a cornhole game yourself isn't just cheaper, it's actually dead simple if you skip the mistakes I made the first time.
When my neighbor Dave saw my homemade boards last summer, he couldn't believe they weren't store-bought. "You built these in your garage?" he kept asking. That's when I knew I had to share exactly what works and what doesn't. No fluff, no complicated jargon – just the straight talk I wish I'd heard before ruining two sheets of plywood.
What You Absolutely Need Before Starting
Listen, I tried cheating on materials once. Used cheap plywood from the discount pile. Big mistake. After three weeks in the sun, those boards warped like potato chips. Save yourself the headache with this shopping list:
| Material | Quantity | Notes | Approx. Cost |
|---|---|---|---|
| 1/2" cabinet-grade plywood | 2 sheets (4'x4') | NOT construction grade! Must be smooth both sides | $50/sheet |
| 2x4 lumber (8ft) | 3 boards | Choose straight boards - check for bends | $5/board |
| Wood screws (2.5") | 1 box (50ct) | Deck screws work best | $8 |
| Wood glue | 1 bottle | Waterproof is better | $5 |
Must-have tools you probably already own:
- Circular saw or table saw (don't try freehand cutting with a jigsaw like I did – wavy edges ruin everything)
- Drill with Phillips bit
- Tape measure and carpenter's square
- Sandpaper (80 grit and 220 grit)
- Clamps (you'll need at least 4)
Pro Tip: Buy 10% extra material. My first attempt ended with a half-inch gap because I measured a cut wrong. Rookie move.
Official Cornhole Dimensions You Shouldn't Ignore
Tournament players will roast you if your dimensions are off. Trust me, I showed up to a BBQ with slightly oversized holes once. Never heard the end of it. Here's what matters:
| Component | Regulation Size | Why It Matters |
|---|---|---|
| Board surface | 48" long x 24" wide | Smaller boards make scoring too easy |
| Hole diameter | 6" exactly | Even 6.5" throws off gameplay |
| Hole position | 9" from top, 12" from sides | Affects bag slide and bounce |
| Front height | 3"-4" | Higher = harder slide |
| Back height | 12" | Standard ramp angle |
See that back height? That's the difference between bags sliding in beautifully or bouncing off like popcorn. Learned that after building my first set with an 11-inch back. Total disaster.
Building Your Boards Step by Step
This isn't rocket science, but there are tricks to avoid wonky boards:
Cutting the Frame
Cut your 2x4s into these pieces:
- 2 pieces at 48" (sides)
- 2 pieces at 21" (front/back - remember to account for thickness!)
Why 21" for front/back? Because 24" width minus 1.5" per side (thickness of two 2x4s) = 21". Math I wish I'd done before cutting.
Assembling the Frame
- Lay out rectangle with corners perfectly square
- Pre-drill holes to prevent splitting
- Glue AND screw joints (glue alone fails in humidity)
Attaching the Playing Surface
This is where most DIYers mess up:
- Cut plywood to 48"x24"
- Apply glue to frame edges
- Place plywood on frame
- Clamp every 6 inches
- Screw every 8 inches from underneath
Warning: Don't screw from the top! Those screw heads will destroy your bean bags faster than my dog destroys shoes.
Cutting the Hole
Measure twice, cut once:
- Mark center point 9" from top
- Use hole saw attachment on drill
- Cut slowly to avoid plywood tear-out
My first hole looked like a beaver chewed it out because I rushed. Sanding fixed it, but sanding curved edges sucks.
Making Cornhole Bags That Last
Store-bought bags rip. Period. Making your own costs $15 versus $30 retail. Here's the real deal:
| Filling Material | Pros | Cons | My Recommendation |
|---|---|---|---|
| Whole kernel corn | Traditional feel | Attracts rodents, molds if wet | ⭐️ Avoid unless indoor-only |
| Plastic pellets | Weatherproof, consistent weight | Feels "cheap" to purists | ⭐️⭐️⭐️ Best for durability |
| Dried beans | Cheap, natural feel | Crumbles over time | ⭐️ Okay for temporary sets |
Bag sewing steps that work:
- Cut duck canvas to 7"x7" squares
- Sew three sides inside-out (1/2" seam)
- Turn right-side out
- Fill with 14-16oz of pellets
- Fold raw edges inward, topstitch closed
Make 8 bags total - 4 of each color. And for god's sake, double-stitch the seams. My first batch exploded mid-tournament. Corn everywhere. Humiliating.
Finishing Touches That Matter
Unfinished boards warp. Badly. Here's how to seal them right:
- Sanding: Start with 80 grit to remove splinters, finish with 220 for smoothness
- Primer: Use oil-based primer (water-based raises wood grain)
- Paint: Semi-gloss exterior paint won't get sticky in heat
- Sealer: 3 coats of water-based polyurethane
Spray painter's trick: Lightly scuff surface with Scotch-Brite between poly coats. Makes finish bulletproof.
Design ideas that actually work:
- Team logos (use stencils)
- Solid colors with contrasting hole ring
- Stripes (mask with painter's tape)
- Avoid dark colors - heats boards unevenly
Real Cornhole Rules People Actually Follow
Nobody agrees on rules? Wrong. Tournament standards prevail:
- Distance: 27 feet between front edges (33ft for pros)
- Scoring:
- Bag on board = 1 point
- Bag in hole = 3 points
- Cancel scoring (only difference counts)
- Throwing: Must release before foul line
- Winning: First to 21 exactly (go over = reset to 15)
What about windy days? You'll curse yourself for not weighting the boards. Simple fix: screw small L-brackets to the underside where legs meet. Hang sandbags during play.
Fixing Common Cornhole Building Mistakes
We've all been there. Here's how to salvage screw-ups:
Wobbly Boards
Diagnosis: Uneven leg lengths or loose joints
Fix: Add adjustable furniture pads to legs
Bags Bouncing Off
Diagnosis: Surface too rough or slick
Fix: Lightly sand with 220 grit and add 2 more poly coats
Water Pooling
Diagnosis: No drainage in hole
Fix: Drill two 1/4" holes in bottom corners
Cornhole DIY FAQ
Can I make cornhole boards from pallet wood?
Technically yes. But they'll warp by next season. Pallet wood's moisture content is inconsistent. Better for practice sets.
How much does it cost to make a cornhole game?
My last set cost $110 vs $250-$400 retail. Breakdown: $100 lumber, $10 hardware. Don't include tools.
What's the best wood for homemade cornhole?
Baltic birch plywood. Stays flatter than standard ply. Pine frames are fine.
How long does building take?
Weekend project: Cutting/assembly (4 hours), painting/drying (48 hours). Rushing paint = sticky mess.
Can you use MDF instead of plywood?
Only if you want ruined boards after one rain. MDF swells like a sponge. Just don't.
My Personal Cornhole Building Blunders (So You Avoid Them)
Year 1: Used interior paint. First hot day = sticky bags everywhere. Had to strip and repaint.
Year 2: Didn't seal hole edges. Bean bags snagged and tore constantly. Solution: Router with 1/4" roundover bit.
Year 3: Built foldable legs. Bad idea. Wobbled like a drunk. Fixed with solid frames.
Now? My boards are on season five. Survived Midwest winters. Outlasted three store-bought sets my buddies bought. Learning how to make a cornhole game properly pays off.
Final thought: The hardware store guys will try to upsell you fancy tools. Don't bite. A basic circular saw and drill get it done. Save that cash for beer to enjoy while playing.
