16 oz boxing gloves are for sparring. Rival puts 16 oz at 150–185 lb (68–84 kg) for sparring; Fairtex at 190–205 lb (86–93 kg). Most adults spar in 16 oz, and many gyms require it for adult sparring. The hand band for the cuff is 7.5–8.5", measured without wraps.
What 16 oz is for
16 oz gloves are made for sparring. Top Ten lists 16 oz for sparring (heavyweight) at 80+ kg.
16 oz carries 4 oz more padding than a 12 oz bag glove to protect the partner, and 16 oz is what most UK clubs require for adult sparring. It is not wider inside: the hand band decides the fit.
Bodyweight bands differ by brand
Rival’s adult sparring chart puts 16 oz at 150–185 lb (68–84 kg); Fairtex at 190–205 lb (86–93 kg).
Where the two disagree for a 190–205 lb boxer, sparring takes the heavier answer and bag work the lighter.
Hand and wraps
Measure the hand round the knuckles with the thumb out, without wraps. Rival’s 16 oz band is 7.5–8.5". Wraps fill part of the glove: at the top of the band with 180" wraps on, go one rung up.
Lighter: 14 oz. Heavier: 18 oz.
