Baseball Glove Size Calculator

A baseball glove size chart matches glove size to your age and position. For adults (13+): infield glove size 11–12 in, outfield glove size 12.5–12.75 in, pitcher glove size 11.5–12.5 in, utility 11.75–12.5 in, first base mitt size 12–13 in, and a catchers mitt size chart range of 32–34 in circumference. Youth players (12 and under) need smaller gloves: roughly 9–12 in depending on age. Use mode 1 above with your exact age and position for a precise baseball glove size by age and position.

A 10 year old typically needs a youth baseball glove in the 10–11.5 in range (youth baseball glove sizes follow the Wilson youth chart). By position at age 10: infield 10.75–11.5 in, outfield 10.75–11.5 in, pitcher 10.75–11.5 in, and first base 11.5–12 in. If your 10 year old plays catcher, look at the youth catchers mitt size range of 29.5–31.5 in circumference instead.

Baseball glove sizes by position reflect what each spot demands. Infield gloves are the smallest with shallow pockets for fast transfers (adult 11–12 in); outfield gloves are the longest with deep pockets for reach (12.5–12.75 in); pitcher gloves sit near infield sizes with a closed web to hide the grip (11.5–12.5 in); utility gloves bridge positions (11.75–12.5 in); first base mitts add length and padding (12–13 in); catcher mitts drop the individual fingers for maximum padding and are measured in circumference (32–34 in circumference).

The fastpitch vs slowpitch glove difference comes down to ball size and pocket depth. Adult fastpitch softball glove sizes: infield 11.5–12 in, outfield 12–13 in, pitcher 12–12.5 in — smaller, with a narrower hand opening and often an open web. Slowpitch softball glove sizes: infield 12–13 in, outfield 12.5–14 in — larger, with a deeper, wider softball glove pocket depth to handle the 12-inch ball, often with a closed web.

A catcher’s mitt is sized by catchers mitt circumference, not length — measured around the outside of the mitt. Adult catchers measure 32–34 in circumference; youth catchers mitt size runs 29.5–31.5 in circumference. Softball catchers mitt size is similar: youth fastpitch 31–32.5 in, adult 32.5–34.5 in circumference. Choose the smallest mitt that fits your hand comfortably; a loose mitt slows your throw to second.

First base mitt size for adult baseball is 12–13 in, measured in length like a fielder glove. Adult fastpitch first base mitts run 12–13 in as well. A first base mitt is longer than an infield glove with extra padding, a shallow pocket and an open or single-post web for scooping low throws.

Here is how to measure baseball glove size at home: lay the glove flat and run a tape from the top of the index-finger stall down to the heel of the glove — that length in inches is the glove size. Catcher’s mitts are measured differently: tape around the full circumference of the mitt. Every baseball glove size chart is built on this measurement, so match your tape reading to the chart range for your position.

The two finger glove test is a quick glove fit check: put the glove on and slide two fingers between your palm and the glove’s heel. If two fingers slide in loosely, the glove is too big; a snug fit with slight resistance is right. Also try the close test — you should be able to squeeze the glove shut with one hand using moderate effort. A glove that is too large slows transfers and swallows a smaller hand.

This method for how to break in a baseball glove works for baseball and softball gloves alike: apply a thin coat of baseball glove break in oil (wipe off the excess), pound the pocket with a mallet 100+ times, play catch daily, and store the glove with a ball wrapped in the pocket overnight. Use the break-in advisor in mode 6 — pick your leather type and weekly sessions for a personalized plan. Avoid ovens, microwaves and direct heat — they dry out and crack the leather.

The baseball glove break in timeline depends on leather. Game-ready and factory-broken youth gloves: 0–3 sessions. Partially broken-in top-grain leather: 5–15 sessions. Stiff full-grain pro leather: 15–30 sessions — at 3 sessions a week that is 5–10 weeks. Wilson youth patterns need little to no break-in. Timelines are guidance only; actual time varies with leather and use.
