A glove size chart beats guessing by exactly one tape measure — — measure around the knuckles, match the chart, and order gloves that fit. This free calculator does the conversion; the inventory lives on cut-resistant gloves and leather work gloves. The printable chart and measuring procedure live in the glove size chart, with nitrile-specific stretch-fit rules in the nitrile glove sizing guide.
How do you measure a hand for the glove size chart?
Short answer: wrap a tape around the dominant hand’s knuckles excluding the thumb — roughly 7 inches maps to Small through 11 inches to 2XL. Enter the measurement below and the calculator sizes you across the common charts.

A glove that is too big snags and slips; too small and it tires the hand and tears. Measure around your dominant hand and this tool gives your numeric and letter glove size. Industrial glove size equals the hand circumference in inches.

FAQ
How do I measure?
Wrap a tape measure around the widest part of your palm, just below the knuckles, excluding the thumb. Use your dominant hand. The circumference in inches is your numeric glove size.
Between two sizes?
For dexterity work (assembly, inspection) size down for a snug fit; for liners, cold-weather, or chemical gloves worn over liners, size up.
General sizing guidance; cut, chemical and disposable lines vary by manufacturer — check the specific size chart. Disposable exam gloves typically run S/M/L/XL rather than numeric.

Our methodology
The calculator uses the knuckle-circumference convention common across US work-glove charts, with the honest caveat that brands drift half a size and the listing’s own chart wins. Authoritative duties live at OSHA regulations and exposure science at NIOSH. We hold no safety certification, and this tool is not a substitute for professional judgment.

Frequently Asked Questions
Knuckles or palm — where do I measure?
Around the knuckles of the flat dominant hand, excluding the thumb — the convention nearly every US chart uses.
Between sizes — up or down?
Down for knit and dexterity work, up for leather that packs out — and up whenever liner gloves ride underneath.
Do brands size the same?
Within half a size, usually — the listing’s own chart overrides this general converter every time it disagrees.
Why does glove fit matter for safety?
Loose fingertips fold into pinch points and lathes; tight shells fatigue grip. Fit is a hazard variable, not comfort trim.
How do I size for liner-plus-shell?
Measure with the liner on — the shell must fit the system, and winter programs size the outer glove accordingly.
Does hand dominance matter?
Measure the dominant hand — it runs slightly larger, and the pair should fit it.
