Glove sizing: ounces and fit
Glove “size” is mostly weight, measured in ounces — and the weight is about padding volume, not hand size. Here is the system everyone uses but nobody explains.
What the weights mean
| Weight | Typical use |
|---|---|
| 8–10oz | Competition (per ruleset) and some pad work for smaller athletes |
| 12oz | Bag and pad work for lighter athletes; all-round use for smaller frames |
| 14oz | All-round training for mid-sized athletes; light partner drills |
| 16oz | The default sparring weight in most gyms, and the safe all-round buy for most adults |
How a glove should fit
- Always try gloves over wrapped hands — that's how you'll wear them.
- Fingertips should reach the top of the glove without jamming; hand shouldn't swim.
- Closed fist should feel snug and aligned — no knuckle pressure points.
- Wrist closure should support without cutting circulation.
- Expect the fit to loosen slightly as the glove breaks in — don't buy so tight that break-in makes it sloppy.
Measuring before you buy
If you're buying online without trying a pair on, wrap a soft tape measure around your knuckles (excluding the thumb) to get a rough hand circumference, and check it against the specific maker's size chart rather than a generic one — charts vary enough between brands that a "medium" from one isn't a safe assumption for another.
Sizing for smaller hands and kids
Adult unisex sizing covers most adults reasonably well, but below a certain hand size the fix isn't just a lighter ounce weight — it's a properly proportioned junior glove with a narrower palm and shorter cuff. See kids' and youth gear for why scaling an adult glove down doesn't solve the same problem.
Common mistakes
- Buying 10oz “because pros wear them” — pros compete in them; they train mostly in bigger gloves.
- Sizing down to “hit harder” on the bag — that's what ruins knuckles.
- One pair for everything forever — a bag pair and a sparring pair outlast and outperform a single dying pair.
- Ignoring your gym's sparring-weight rule in favour of a personal favourite pair.
