The Ultimate Fighting Championship introduced two weight classes at UFC 12: Heavyweight, which had competitors above 200 lb (91 kg), and Lightweight, which grouped competitors under 200 lb.
The UFC gradually introduced various weight classes, and the promotion currently consists of 12 different weight classes, with non-title fighters allowed a one-pound leeway, while title fights require exact weight or less. Missing weight can lead to fines, a catchweight bout, or fight cancellation.
