What is the maximum fight weight for the UFC’s men’s flyweight division?

The maximum fight weight for the UFC’s men’s flyweight division is 125 pounds.

Under the Unified Rules of Mixed Martial Arts, a non-title flyweight bout allows a one-pound allowance, while a title fight is generally limited to 125 pounds. The division sits above the UFC’s strawweight category and below bantamweight.

The UFC launched its men’s flyweight division through a tournament in 2012. Demetrious Johnson became the inaugural champion after defeating Joseph Benavidez in the tournament final at UFC 152. Johnson later became known for a record-setting run of successful defenses.

Weight limits can be confused with the division names used in boxing or with non-UFC promotions, where classifications and allowances may differ. In UFC usage, men’s flyweight refers to the 125-pound class, while women’s flyweight is a separate 125-pound division.
