USSSA youth bat rules

Travel and select tournaments often use USSSA rules. Event directors can add drop or barrel limits — read the event page.

Required markUSSSA BPF 1.15

Stickers / decalsNot valid

USA-only batsUsually not enough

Withdrawn modelsCheck non-compliant list

Core requirements

Bat must comply with the USSSA 1.15 BPF performance standard and testing protocol.
The USSSA certification mark and graphics must be permanent and applied only by a current USSSA-licensed manufacturer.
Using stickers, or adding graphics after manufacturing, can make the bat an “altered bat.”
Models on USSSA’s non-compliant / withdrawn lists are illegal even if they once carried a stamp.

Licensed bat manufacturers (USSSA list, updated late 2025) include Axe, DeMarini, Easton, Louisville Slugger, Marucci, Mizuno, Rawlings, Victus, Warstic, and others.

Some orgs (e.g. certain Perfect Game age brackets) allow USABat or BBCOR in addition to USSSA, or ban specific drops like −5 at 12U. Never assume — check that weekend’s rule sheet.

Barrel size by age Published limits

Maximum barrel diameter (inches) commonly published for this program. Length and drop limits are separate — check the notes.

Age / division	Max barrel	Notes
Small barrel (any age where allowed)	≤ 2¼″	USSSA mark (or wood) from licensed manufacturer
Big barrel — 14U & below	2⅝″ or 2¾″	USSSA 1.15 mark, BBCOR, or wood (licensed)
Big barrel — 15U & above	2⅝″ or 2¾″	NFHS BBCOR mark or wood (licensed); youth USA/USSSA stamps alone are not enough
Drop notes (national bylaws)	See notes	13U max drop −8 (Elite WS tighter); 14U national standard moving to −3 BBCOR with state −5 exceptions

USSSA classifies small (≤2¼″) vs big (2⅝″/2¾″) barrels rather than banning 2¾″ in youth. Event directors and states often add tighter drop/barrel caps — read the event page.
