About this calculator
The calculator converts circumference to inches and rounds to a half-size reference. It uses a fixed offset for the UK label and converts the US value to a centimetre reference. This simplified mapping is not a fit guarantee; glove charts and preferred ease vary by maker.
Worked example
calculated with the default values below
Hand circumference (selected unit) 8 · Measurement unit Inches US glove size 8 · UK glove size 8 · EU glove size 21

Disclaimer
These calculators give general estimates. Sizing, pricing, availability and standards vary by brand, retailer and country, so treat the output as a starting point and confirm it against the seller's or authority's own figures.

This record describes the implementation used by this page. It is not independent validation. External references, when available, support only the stated formula or definition; estimates and custom rules retain their own assumptions.
Formula and variables
US = round(2c)/2; UK = round(2(US−0.5))/2; EU = round(2×2.54×US)/2

US reference = hand circumference in inches rounded to the nearest 0.5; UK reference = US − 0.5; EU reference = US × 2.54 cm. This is a simplified crosswalk, not a fit guarantee.
Frequently asked questions
How are glove size references calculated?
The hand circumference is converted to inches and rounded to the nearest half size for the US reference. The UK estimate subtracts 0.5; the EU reference converts that US value to centimetres. This simplified mapping may differ from a maker’s chart and preferred fit.
