Boxing Weight Divisions Explained

Boxing originally had eight classic divisions, from flyweight at 112 pounds to heavyweight. Today there are 17 or more recognized classes, with super and junior prefixes filling the gaps, plus bridgerweight.

The purpose is safety: matching fighters of similar mass. Legends defined divisions rather than skipping them, Robinson at welterweight, Duran at lightweight, Hagler at middleweight.

Modern stars chase multi division glory, Canelo from 154 to 175, Inoue from 108 to 122, Pacquiao an unmatched eight. Catchweights and rehydration clauses complicate modern matchmaking..
