Glove sizing is driven by one measurement — the circumference of your hand around the palm. This chart turns that measurement into the three sizing systems you will encounter on labels: the familiar Small / Medium / Large bands, US numeric sizes, and EU numeric sizes.
How it works
Glove sizes are tied directly to hand circumference. The US numeric size is, by long convention, approximately the hand circumference measured in inches:
US size ≈ hand circumference in inches
S/M/L = band the circumference falls into
EU size ≈ US size + 1 to 2 (varies slightly by maker)
The tool stores a fixed table of circumference ranges and their matching sizes. When you enter a measurement it converts to a common unit, finds the band your hand falls into, and reports the letter, US, and EU sizes together.
Tips and notes
- Measure the dominant hand; it is usually the larger of the two.
- Exclude the thumb from the measurement — wrap around the palm only.
- For insulated or lined work gloves, size up one band.
- A correct glove lets fingertips reach the end without bunching, with no excess fabric across the palm.
For example, a hand circumference of 8.5 inches (about 21.6 cm) falls in the
Medium / US 8 band, roughly an EU 9.
