Youth Baseball Mitt Size Chart | Age & Position Guide

Guide / By

A youth baseball mitt size chart matches glove size to the player’s age range and position, with catcher’s mitts measured by circumference and all other gloves measured by length.

Choosing the right baseball mitt can make or break a young player’s confidence in the field. A glove that’s too big leads to dropped balls and frustration. One that’s too small leaves the hand unprotected and uncomfortable. The right approach uses age and position as a starting point, then adjusts for the child’s actual hand size. Our youth baseball mitt roundup covers top-rated models, but here’s how to nail the size first.

How Youth Baseball Mitt Sizing Works

Standard baseball gloves are measured by length: from the tip of the index finger to the center of the heel. Catcher’s mitts are the exception — they’re measured by circumference, or the distance around the outer edge of the mitt when it’s opened flat.

To measure a glove, use a flexible tape measure, not a stiff ruler. For a standard glove, run the tape from the finger tip to the heel center. For a catcher’s mitt, spread the mitt palm-side down and measure the full perimeter. Youth sized gloves usually span 9 to 13 inches in length, while youth catcher’s mitts range from 29.5 to 32.5 inches in circumference.

Position matters more than age alone. A shortstop and an outfielder the same age need different glove sizes: infielders want a smaller glove for quicker transfers, while outfielders benefit from a longer reach.

Youth Baseball Glove Size Chart by Age and Position

The table below compiles the most commonly cited size ranges from baseball equipment guides. Age bands are guidelines, not strict rules — a small 10-year-old may fit better in the younger bracket, while a larger 9-year-old might prefer the next size up.

Player Age Position Glove Size (inches)
Under 7 Catcher 29.5–30″ circumference
Under 7 First Base 11.5″
Under 7 Infield / Outfield 8–10.5″
8–10 Catcher 30–32″ circumference
8–10 First Base 11.5–12″
8–10 Second Base / Shortstop 10.5–11.25″
8–10 Third Base 10.5–11.5″
8–10 Outfield 10–12″
11–13 Catcher 31–32.5″ circumference
11–13 First Base 11.5–12″
11–13 Second Base / Shortstop 11–11.5″
11–13 Third Base / Pitcher 11.5–12″
11–13 Outfield 11.5–12.75″
14 and over Catcher 32–34.5″ circumference
14 and over First Base 12–13″
14 and over Infield 11.25–12″
14 and over Outfield 12–13″

Common Sizing Mistakes to Avoid

Five errors cause most wrong-size purchases. First, measuring a catcher’s mitt by length instead of circumference — the two numbers are completely different and can’t be compared. Second, buying by age alone and ignoring the position: a 10-year-old catcher and a 10-year-old outfielder need different mitts. Third, using a stiff ruler instead of a flexible tape, which underestimates the size. Fourth, measuring without flattening the mitt open, especially for catcher’s mitts. Fifth, skipping league size limits — some youth leagues cap glove sizes, and a mitt that’s too big might not be legal on game day.

Here’s the other caveat most guides skip: youth players should usually size down, not up. A glove that looks “room to grow” is often too big to control. A slightly snug glove that the child can open and close easily will build better fielding habits than a larger one they struggle to squeeze.

Do You Need a Catcher’s Mitt or a Fielding Glove?

Catcher’s mitts and fielding gloves are different equipment. A catcher’s mitt has extra padding and a closed web designed to absorb pitch impact, and it’s always measured by circumference. Fielding gloves come in open or closed webs and are measured by length. Youth catchers aged 12 and under typically use a mitt sized 32 inches or smaller in circumference, while teens move into the 32.5 to 34.5 inch range.

For first base, the mitt is also measured by length, usually 11.5 to 13 inches for youth players. Standard infield and outfield gloves in this age range generally fall between 8 and 13 inches, with the smaller end for second base and shortstop and the larger end for outfield.

Here’s one last tip: have the child try the glove on with a baseball in it. A mitt that fits well allows a firm grip on the ball without the glove flopping or the hand slipping around inside. That real-world test beats any chart.

Check with your league for any glove size restrictions before buying. For reliable sizing data, see Dick’s Sporting Goods’ baseball glove buying guide and BaseballMonkey’s youth glove sizing page.

FAQs

How do I measure my child’s hand for a baseball glove?

Measure the distance from the tip of the index finger to the center of the palm heel. That gives you the approximate glove length needed. For a catcher’s mitt, you measure the mitt itself by circumference, not the hand.

Can a youth player use an adult glove?

Generally no. Adult gloves start at 12 inches and are heavier and stiffer, making them hard for a child to close quickly. A glove sized for the player’s age and position gives better control and builds correct fielding form.

What size glove does a 12-year-old shortstop need?

Most 12-year-old shortstops fit a glove in the 11 to 11.5 inch range. That length allows quick ball transfer for double plays while still providing enough reach for ground balls in the hole.
