- EN 420 / ISO 21420-style numeric sizes roughly track hand circumference in inches (size 8 ≈ ~8 in / ~20 cm around the knuckles).
- Letter S/M/L and numeric 7/8/9 are educational matches—brands still print their own charts.
- Thick cut-resistant or 6–8 mil nitrile often runs small—try one size up if the film tears at the thumb crotch.
- European motorcycle brands often use numeric sizes and a tighter cut than US letter gloves.
FAQ
- How do I convert hand circumference to glove size?
- Measure around the knuckles with the thumb out, enter centimeters or inches in the finder, then read the unisex letter and numeric size. Confirm the brand chart before you buy.
- What is glove size 8 or 9?
- Numeric work and EU-style sizes roughly track hand circumference in inches—size 8 is near 8 in (~20 cm), often letter M; size 9 is near 9 in (~23 cm), often L.
- Is letter size the same as numeric glove size?
- They are related but not identical labels. This converter maps both from the same knuckle measurement. Brands may still shift half a size.
- Should I size up for work or winter gloves?
- Size up for thick liners, cut-resistant shells, or 6–8 mil nitrile that runs small. Dress leather usually stays snug on the smaller letter if you are between rows.
