MMA divisions
Fighters are matched inside weight classes. Counts are fighters with a bout on record in the last 4 years.
Three names — flyweight, bantamweight and featherweight — are used by both the men’s and the women’s divisions at different limits, which is why the women’s classes are named in full here.
- Strawweight60 fighters
- Women's Flyweight64 fighters

- Women's Featherweight8 fighters
- Featherweight131 fighters
- Lightweight145 fighters
- Welterweight122 fighters
- Middleweight109 fighters

A bout contracted outside all of these is a catchweight — a one-off weight both camps agree to, rather than a division anyone belongs to.
