Baseball Glove Sizing: Position-by-Position

By Emma Wilson · October 11, 2026

Why Glove Size Matters

The right glove size improves fielding consistency, transfer speed, and overall comfort. Too large and the glove is unwieldy; too small and you'll miss balls that should be routine catches.

Infielder Gloves (11-12 inches)

Infielders need smaller, shallower gloves for quick ball retrieval. Second basemen typically use 11-11.25 inch gloves, while shortstops and third basemen prefer 11.25-11.75 inches.

Shallow Pocket Design

Infielder gloves feature shallow pockets and open webbing to allow fast ball transfer from glove to throwing hand. Every fraction of a second matters when turning double plays.

Outfielder Gloves (12.5-13 inches)

Outfielders use larger gloves with deeper pockets to secure fly balls and line drives. The extra surface area provides a larger margin of error on difficult catches.

First Base Mitts (12-13 inches)

First base mitts are longer and lack individual finger slots, creating a larger target for throws. The extra length helps scoop balls in the dirt from infielders.

Catcher's Mitts (32-34 inch circumference)

Catcher's mitts are measured by circumference rather than length. They feature extra padding and a closed web to withstand the impact of pitches at high velocities.

Breaking In Your Glove

New gloves require 2-4 weeks of regular use to properly break in. Apply glove oil sparingly, play catch daily, and store the glove with a ball in the pocket to form the right shape.
