A cornhole bag is legal for ACL play only if it comes from a manufacturer on the current annual approved list and hits the size, weight, and thickness limits.
Swap in a bag that misses the list by one season and a sanctioned match can turn into a forfeit. The American Cornhole League ties bag legality to three things at once: an approved manufacturer, exact physical specs, and an untouched purchase condition. Miss any one of them and the bag sits out. Here’s the whole checklist, plus the mistakes that quietly disqualify a set.
The Three Rules That Decide Legality
A bag passes ACL scrutiny when it is player-supplied, printed on the current Approved Bag Manufacturer List, and built to the ACL’s measurements — not one of those, all three.
The approval list is republished every season, which is why last year’s legal bag can be this year’s problem. From there, the specs are strict and measurable:
- Width and length: 6 inches by 6 inches, with a tolerance of plus or minus 1/4 inch — about 5.75″ to 6.25″ measured flat.
- Weight: 15.5 to 16.5 ounces. Older ACL rule PDFs list a tighter 15.5 to 16.25 ounces, but current ACL pages use the wider range.
- Thickness: no less than 1.1 inches and no more than 1.5 inches, with roughly 1.3 inches as the target.
- Set matching: all four bags in a set must match in design and color on each side.
The ACL also flags bags marked ACL Pro or ACL Comp as suitable for competitive play, and older rule PDFs call for a manufacturer logo or stamp on the bag itself.
| Legal Bag Standard | Accepted Measurement | Why It Disqualifies A Set |
|---|---|---|
| Width and length | 6″ x 6″ (±1/4″) | An off-size bag won’t sit flat on the board face |
| Weight | 15.5–16.5 oz | Lighter bags slide instead of gripping on impact |
| Thickness | 1.1″–1.5″ (target 1.3″) | A thin bag flattens and changes how it slides |
| Resin condition | No holes, no leaking resin | A leak means the bag no longer matches its approved build |
| Alterations | None after purchase | Resin swaps, ironing, or repairs void the original spec |
| Set uniformity | Four bags identical per side | A mismatched set gives one player an unfair read |
| Approved list | Current season’s manufacturers | The right dimensions can’t rescue an unlisted brand |
Buying a set that already clears every tolerance saves a lot of measuring at check-in, and a tested roundup of ACL-legal cornhole bags worth buying is a useful starting point before you compare the specs below.
How Do You Actually Verify a Bag Before Play?
Verification runs in four short steps, and each one catches a different failure a single glance would miss.
- Confirm each bag is on the current season’s ACL Approved Bag Manufacturer List — and the current season ACL Approved BYOB Bags List if the event runs the ACL BYOB policy.
- Lay the bag flat and measure it: 6″ x 6″, 15.5–16.5 oz on a kitchen scale, 1.1″–1.5″ thick at the seam side.
- Inspect for holes, leaking resin, mismatched set pieces, and any alteration that changed the bag from purchase condition.
- Check the whole set matches in design and color before you bag it up for the event.
The ACL’s bags and equipment guidelines lay out these specs directly, and the ACL official rules and regulations page carries the current weight range when the two ever disagree.
Maintenance And Mid-Game Rules
Cleaning is allowed within limits: washing with detergent or fabric softener and machine drying won’t disqualify a bag, but applying anything to the outside of it will.
On the material front, the ACL reserves the right to rule a bag or material not permitted if it damages boards or leaves residue — a real risk with untested resins. Once a game is under way, you can’t swap bags except for unintended damage, leaking, or an alteration that affects play, and a damaged bag can force a full set replacement at the end of the round.
One last caution worth repeating: other organizations publish their own, looser “regulation” numbers. A bag built to someone else’s spec isn’t automatically ACL-legal just because it hits a familiar size or weight. Check the ACL list and the ACL numbers — nothing else.
FAQs
Can you wash cornhole bags without making them illegal?
Yes, within limits. ACL rules permit washing with fabric softener or detergent and drying in a dryer. What disqualifies a bag is applying foreign substances to the outside, or altering it after purchase through resin changes, ironing, or stitching repairs. Wash them, dry them, and leave the construction alone.
What happens if one bag in a set is damaged mid-game?
You generally cannot swap it out during play unless the damage is unintended and affects the game, such as a hole or leaking resin. In those cases, the ACL can require a full set replacement at the end of the round, so packing a spare legal set is the safe move.
Do older ACL weight specs still apply?
Current ACL pages state 15.5 to 16.5 ounces, while older rule PDFs show a narrower 15.5 to 16.25 ounces. Go with the current range, and weigh your bags on a kitchen scale before a sanctioned event so a tournament official never has to make the call for you.
