NABF bat rules (2026-27)
Which bats are legal in each NABF division, in plain words, with the source and the date we checked it. Pick your division for the full rule and the bats that fit.
Rules checked Oct 27, 2026. Confirm with your league before you buy: local leagues and tournaments can set their own rules, stricter or looser than the national ones.
Some of these rules are still being confirmed (10U to 14U): each division page says why.
| Division | Ages | Bats allowed | Drop limit | Longest |
|---|---|---|---|---|
| 10U to 14U | 10U to 14U | USABat (USA Baseball mark) | None (per USA Baseball) | Not stated |
