A 12" (305 mm) hand round the palm is EN size 12 (3XL), a women's 3XL and a XXL exam glove; in golf outside FootJoy’s men’s chart, goalkeeper size 13 and Alpinestars 3XL. Flat, it measures about 126 mm across the knuckles.
EN ISO 21420 sizes are one inch of circumference apart, so a 12-inch hand is exactly size 12: the table’s 304 mm reference with a typical length of 225 mm.
Size 12 is 3XL on unisex lines and 3XL on women’s lines, which are cut a letter smaller for the same hand.
