How to size a youth baseball glove (by age and position)

Walk any Little League field and you'll see it: eight-year-olds wearing gloves sized for high schoolers, folding like lawn chairs every time a ball arrives. The oversized glove is the most common gear mistake in youth baseball — and unlike bat questions, nobody writes about it.

Here's the sizing guide we give our families.

Why too big is worse than too small

A glove that's too big does three bad things. The kid can't close it — the hand physically can't flex leather built for a bigger palm, so balls pop out. It teaches bad habits — kids start trapping balls against their body instead of catching in the pocket, because the pocket is a mystery somewhere out past their fingertips. And it's heavy — a tired glove arm drops, and dropped gloves mean balls in the face, and balls in the face mean kids who fear grounders for a year.

A snug glove that closes easily beats a roomy one every single time. They'll grow into nothing; they'll develop with what fits today.

Sizing by age

These ranges assume rec or select ball and an average-sized kid. When in doubt, size down.

Ages 5–7: 9" to 10.5". At this age the glove is mostly a leather introduction. Light and closable matters more than anything.

Ages 8–10: 10.5" to 11.25". The real development years. This is where the wrong glove does the most damage, because this is when catching mechanics get wired in.

Ages 11–13: 11" to 11.75", and position starts to matter (below). Kids this age often want the 12.75" outfield flag their favorite MLB player uses. Hold the line.

Ages 14+: essentially adult sizing — 11.25" to 12" infield, 12.5" to 12.75" outfield.

Sizing by position

Once a kid settles into a position around 11U:

Middle infield: small and shallow — 11" to 11.5". Quick transfers beat big pockets.

Third base: 11.5" to 11.75" with a deeper pocket for hard hops.

Outfield: longer, 12" to 12.75", for reach on fly balls.

Pitcher: 11.5"-ish with a closed web to hide grips.

Catcher and first base: their own mitts entirely — a catcher's mitt sized 31"–32.5" for youth, and a first-base mitt only once they're committed to the spot.

A utility kid does not need five gloves. One 11.25"–11.5" infield glove covers everything until a position sticks.

Breaking it in without ruining it

Skip the oven, the microwave, and the shaving cream folklore. The method that works: a light coat of glove conditioner, a ball in the pocket, a strap or rubber bands overnight, and then the only thing that actually breaks in a glove — catch. A few hundred catches shapes leather to your kid's hand in a way no shortcut can.

Which is convenient, because a few hundred catches is also just called practicing.

The five-second store test

Have your kid put the glove on, hold their arm out, and squeeze. If they can close it one-handed, easily, all the way — it fits. If they need their other hand to help fold it, it's too much glove, no matter what the size chart says.
