Catcher’s Mitt Size Chart: Sizing Guide by Age & Level
Most baseball catchers use a catcher’s mitt between 32 and 34 inches; most fastpitch catchers use 33 to 35 inches. Catcher’s mitts are measured by circumference, not heel-to-fingertip like a fielder’s glove. Age picks the row in the chart below; the hand picks the mitt. Youth players should almost always size down from where parents expect — an oversized mitt teaches stabbing instead of receiving.
Catcher’s mitt size chart by age and level
| Age / Level | Baseball mitt | Fastpitch mitt |
|---|---|---|
| 7 & under | 29.5″–30″ | 29.5″–30.5″ |
| 8–10 | 30″–31.5″ | 30″–32″ |
| 11–13 | 31″–32.5″ | 31.5″–33″ |
| 14 – High school | 32″–33.5″ | 33″–34″ |
| Adult / College+ | 33″–34.5″ | 33″–35″ |
Two players the same age can need different catcher’s mitt sizes — hand size and league ball rule the decision, and age only gets you to the right row. If your player sits between rows, size for the hand, not the birthday.
How to use this catcher’s mitt size chart
- The chart is a shortlist, not a verdict. It reflects the size ranges manufacturers actually ship for each level; it does not override a hand measurement.
- There is no governing sizing standard across brands. Two 33-inch mitts from different makers can fit differently at the wrist and close differently in the pocket.
- Fastpitch rows run larger on purpose — a 12-inch softball against a 9-inch baseball changes the pocket depth and the circumference required.
- Re-measure youth catchers every season. Hands move rows faster than gear budgets do.
How catcher’s mitts are measured
Catcher’s mitts are the only gloves on the field measured by circumference — the distance around the outside edge of the mitt. Fielder’s gloves are measured heel to fingertip, which is why an 11.5-inch shortstop glove and a 33-inch catcher’s mitt can sit side by side in the same dugout without one dwarfing the other.
That difference matters when you shop. A 33-inch catcher’s mitt is not monstrously bigger than a 12.5-inch glove — it is a different measuring tape entirely. When a size chart mixes gloves and mitts in one table without saying so, walk away from it.
How to measure for a catcher’s mitt
Measuring for a catcher’s mitt takes a flexible tape measure and two minutes.
- Measure the hand. From the tip of the index finger down to the wrist crease, in inches, throwing hand relaxed.
- Match it to the chart row for your league and age group above.
- Check the wrist opening when you try the mitt on. Snug enough that the mitt does not rotate when you squeeze, loose enough to rip off for a bare-hand play.
- Run the squeeze test. With your hand in the mitt, you should be able to close the pocket fully with one squeeze. If you need your throwing hand to fold it, the mitt is too big or too stiff.
For a young catcher, measure the hand every season. Kids jump rows fast, and a mitt that fit in spring can be fighting them by fall.
Baseball vs fastpitch catcher’s mitt sizing
Fastpitch catcher’s mitts run larger because the ball runs larger — a 12-inch softball against a 9-inch baseball. The pocket is deeper and rounder, the circumference longer, and the break-in points sit differently.
This is why a fastpitch catcher should never be handed a baseball mitt because it happens to fit. The ball will not seat in the pocket, and every catch becomes a snow-cone. A catcher who cannot trust the pocket starts reaching for the ball instead of receiving it, and that habit outlives the mitt.

Youth catcher’s mitt sizing: the one mistake to avoid
Do not buy a youth catcher’s mitt with room to grow. An oversized mitt is the most common and most damaging equipment mistake in youth catching. The player cannot close it, cannot feel the ball, and learns to stab instead of receive.
A youth catcher with a mitt that fits today will out-develop a youth catcher swimming in next year’s mitt, every time. The saved money is real and the cost is invisible until it is permanent: mitts at youth prices are replaceable, and bad receiving habits are not. Buying for the player in front of you rather than the one you are hoping for next season is the whole discipline. When you are ready to shop, our best youth catcher’s mitts roundup is built around exactly this principle, and the budget catcher’s mitts guide covers the grow-fast years.
Adult catcher’s mitt sizing
Most adult baseball catchers land between 33 and 34 inches, and professional catchers cluster tightly in that same band. Bigger is not better past your hand size — every extra half inch adds weight your transfer pays for in the ninth inning, when the game is usually still being decided.
If you catch a knuckleballer or spend hours on receiving drills, specialty sizes exist for both — see our knuckleball catcher’s mitt and training mitts guides.
Catcher’s mitt sizing FAQs
What size catcher’s mitt does a 13-year-old need?
A 13-year-old catcher usually needs a 31 to 32.5-inch mitt for baseball, or 31.5 to 33 inches for fastpitch. Confirm with the hand measurement and the squeeze test before buying. A big-handed 13-year-old can wear a high-school size; a small-handed one should not be pushed into one.
Does age determine catcher’s mitt size?
Age picks the row in a catcher’s mitt size chart; the hand picks the mitt. Use age ranges to shortlist two or three sizes, then fit the actual hand and run the squeeze test.
How do I measure my child’s hand for a catcher’s mitt?
Measure from the tip of the index finger to the wrist crease, in inches, with the throwing hand relaxed. Do it at the start of each season — hands grow faster than gear budgets, and a mitt that fit in spring can be fighting a young catcher by fall.
Are catcher’s mitts one size fits all?
Catcher’s mitts are not one size fits all — sizes run from about 29.5 inches for the youngest players to 35 inches in fastpitch. Fit at the wrist also varies by brand, so two 33-inch mitts from different makers can feel different on the same hand. Try before game day, and break the mitt in before the season starts.
How is a catcher’s mitt measured compared to a fielder’s glove?
A catcher’s mitt is measured by circumference around the outside edge, while a fielder’s glove is measured heel to fingertip. That is why a 33-inch catcher’s mitt and a 12.5-inch infield glove are closer in real size than the numbers suggest. Any size chart that mixes the two measurements in one table without saying so is not worth using.
Bottom line
Size a catcher’s mitt to the hand in front of you, not the age on the roster, and confirm it with the squeeze test before game day. A mitt that fits is the first promise a catcher keeps to a pitcher — everything else behind the plate is built on top of it.
