05 / Field guide
A 6.5" (165 mm) hand round the palm is EN size 7 (S), a women's M and a S exam glove; in golf FootJoy women's S, goalkeeper size 8 and Alpinestars S. Flat, it measures about 68 mm across the knuckles.
EN ISO 21420 sizes are one inch of circumference apart, so a 6.5-inch hand sits halfway between sizes 6 and 7. Unisex work and sports gloves round it to 7 (S); makers that sell half sizes (dress leather, goalkeeper, surgical) make a 6.5.
Between two sizes, a tight-fitting glove (exam, golf, race) usually goes to 6, an insulated or lined one to 7.
6.5" × 25.4 = 165 mm round flat width ≈ 165 ÷ 2.42 = 68 mm (men)
A 6.5" hand is below FootJoy’s men’s chart and reads as a women’s S (6.25–7"); junior golf gloves also fit here.
Goalkeeper gloves add an inch: 6.5" rounds to 7 and becomes size 8 (Reusch’s half-size chart: 6.5). Alpinestars’ men’s chart puts 16.5 cm at S. Hestra winter gloves are a 7 bare, 7 over a 1 mm liner.
For boxing, 6.5" falls in Rival’s 12 oz hand band (90–120 lb), but glove weight is chosen by bodyweight and use first; the hand only says how the cuff fits.
Kids’ sizes near 6.5" (Reusch): 6 for ages 10–12, 6.5 for ages 12–14, 7 for ages 14–16.
