Glove & mitt sizing for high school & adult
Position-true patterns, durable leather, and a fit that matches how you play — not a youth hand-me-up. Reviewed October 23, 2026.
1. Age snapshot
High school and adult players should buy for position first. Adult lengths are standard; the decision is pattern (infield vs outfield vs mitt), web style, and break-in preference. Pair with legal bats — see our BBCOR / NFHS notes for HS hitters.
Typical fielder range: Adult fielder gloves generally 11.5–12.75″ by position. First-base mitts and catcher’s mitts use separate measuring conventions.
How to measure (hand & glove)
- Hand check: With the throwing hand, measure from the tip of the index finger down to the base of the palm (heel). That length is a rough youth “hand size” cue when comparing charts.
- Glove length (fielders): Manufacturers list size in inches — typically measured from the top of the index finger, down the palm, to the heel of the glove.
- Catcher’s / first-base mitts: Measured differently (around the mitt perimeter / specialized scale). Compare mitt-to-mitt using the maker’s youth vs adult labels, not fielder-glove inches alone.
- Fit test: Fingers should fill the stalls without swimming. The player should be able to close the glove on a baseball with reasonable effort after break-in. If they can’t squeeze it shut, it’s too stiff or too big.
- Lefty / righty: “Right-hand throw” gloves go on the left hand (and vice versa). Double-check before you open the box.

2. Sizing by position
- Catcher: ~33–34.5″ catcher’s mitt. Maximum protection and a deep pocket for framing, blocking, and receiving velocity. Pro patterns vary — try on for finger length and thumb stall comfort.
- Infield: ~11.25–12″ (often 11.5–11.75″ for middle infield). — Smaller, lighter, faster transfers. Shallower pocket than outfield. Third base may prefer the larger end of the infield range.
- Outfield: ~12.5–13″ — Larger for reach and ball security. Deep pocket. Choose a web (H-web, trapeze, etc.) that matches preference for visibility vs. deep catches.
- Pitcher: ~11.5–12.5″ — Snug closed-web glove that conceals grip and feels secure on every pitch. Many pitchers use a dedicated closed-web model separate from their infield glove.
First base often uses a dedicated mitt (larger, shallow scoop) once kids play there regularly — usually introduced more seriously around 11U–14U.
3. Quick buying checklist
- Know the primary position (or buy a versatile middle size if they float).
- Match the inch range above — then prioritize a glove they can close.
- Soft / easy-break-in leather beats a stiff “pro” model they can’t squeeze.
- Confirm throw-hand (RHT vs LHT) before checkout.
- Plan break-in time before the first tournament weekend.
