Where the fights happen
UFC divisions
Championship bouts are contested at the limit; non-title bouts allow a one-pound allowance. The notes are SportsArena365's own reading of each division, not a statistic.
Men's divisions
Flyweight
125 lb / 56.7 kg
The fastest division on the roster; volume and footwork usually beat power.

Bantamweight
135 lb / 61.2 kg
Deep and unforgiving — the title has changed hands more often here than almost anywhere.
Champion Not published
Featherweight
145 lb / 65.8 kg
Where cardio and finishing power still coexist over five rounds.

Lightweight
155 lb / 70.3 kg

Welterweight
170 lb / 77.1 kg

Small rosters, short title reigns and very few decisions.
