A softball mitt has a wider, deeper pocket to secure an 11- or 12-inch ball, while a baseball mitt is built narrower with a shallower pocket for a 9-inch ball, making the two designs sport-specific and not interchangeable.
The glove you choose needs to match the ball it will catch, and a softball is roughly three inches larger in diameter than a baseball. That single measurement drives every other difference: pocket depth, mitt width, and even how padding is distributed. If you grab the wrong mitt for your sport, you will fight the gear every play. Here is exactly what changes between the two, mitt by mitt.
Pocket Depth and Glove Width
The pocket is the biggest difference you will feel. Softball mitts use a deeper, wider pocket because a 12-inch softball demands more surface area to secure it. A standard baseball mitt is more compact and has a shallower pocket, designed around a 9-inch ball. Rawlings states that softball models prioritize a larger pocket and more width, while baseball gloves are smaller, narrower, and more compact. This is the first thing to check when picking a mitt.
Catcher’s Mitts: Circumference and Construction
Catcher’s mitts are measured by circumference, not length, and the size gap between sports is real. The most noticeable difference is width: a softball catcher’s mitt will have more receiving surface area and a deeper pocket to help control the larger ball. Baseball catcher’s mitts are usually shallower and carry more padding to absorb the harder, faster baseball. If you try to use a baseball catcher’s mitt for softball, the shallower pocket will make ball retention harder and likely increase drops, a warning several guides emphasize.
First Base Mitts: A Smaller Gap
The key difference is the pocket: softball first base mitts have a wider pocket to match the larger ball. If you play first base in softball, do not grab a baseball first base mitt — the narrower pocket will not secure a thrown softball as reliably.
Construction and Hand Fit
Beyond pocket shape, the overall build varies. Baseball mitts tend to have shallower pockets and, for catcher’s models, more padding specifically for the hard, fast baseball. Softball mitts emphasize a deeper, wider pocket as their primary feature. Some sources note that baseball mitts may have roomier finger stalls or larger palm openings, while softball models are sometimes sized differently for demographics common in softball. This is a design trend rather than a hard rule — try the fit before you buy.

Here is a quick reference on the key measurements:
| Type | Softball Mitt | Baseball Mitt |
|---|---|---|
| Ball size caught | 11–12 inches | 9 inches |
| Catcher’s mitt circumference | 33–35 inches | 31–35 inches |
| First base mitt size | ~12.75–13 inches | ~12–13 inches |
| Pocket depth | Deep and wide | Shallower and narrower |
| Padding emphasis | Ball retention / surface | Impact absorption |
| Measured by | Length (fielding) / Circumference (catcher) | Length (fielding) / Circumference (catcher) |
FAQs
Can I use a baseball mitt for softball practice?
You could, but ball retention will suffer because the pocket is too small and shallow for a 12-inch softball. Expect more drops and less control, especially on catches near the webbing. A softball-specific mitt is the safer choice.
Are first base mitts the same for both sports?
Not exactly. The size is similar — around 12.75 to 13 inches — but a softball first base mitt has a wider pocket to handle the larger ball. A baseball first base mitt’s narrower pocket can struggle with a thrown softball.
Do softball gloves have less padding than baseball gloves?
Typically, yes. Because a softball is larger and softer, the padding emphasis shifts toward ball retention and pocket depth rather than impact absorption. Baseball mitts, especially catcher’s models, often add more padding for the harder, faster baseball.
