UFC women’s flyweight fighters have a 125-pound limit in championship bouts and may weigh up to 126 pounds in non-title bouts. Official weigh-ins are generally held the day before the event, but the event’s athletic commission can affect extra time and the consequences of a missed limit.
What is the UFC women’s flyweight weight limit?
The applicable limit depends on whether the bout is for a title:

| Bout type | Maximum weight |
|---|---|
| Championship bout | 125 pounds |
| Non-title bout | 126 pounds, including the one-pound allowance |
That distinction matters: a title fighter weighing 125.5 pounds is over the championship limit, even though the same weight is below the non-title maximum. UFC’s weight-class and weigh-in explainer gives the 125-pound flyweight limit and the one-pound allowance for non-title bouts.
When are official weigh-ins, and can a fighter try again?
UFC says official weigh-ins generally take place the day before fight night, between 9 a.m. and 11 a.m. local time. Depending on the overseeing commission and how much weight remains, a fighter may be granted an additional hour to make weight. That is a general description, not a guarantee for every event; the commission and event circumstances govern the procedure.
#1 Best Overall
UFC says its bouts adhere to the Unified Rules of MMA, a framework intended to support consistent professional competition across athletic commissions. UFC reports that the Association of Boxing Commissions unanimously adopted the rules on July 30, 2009. For event-specific procedure, the relevant state athletic commission is the authority to consult.
What happens if a flyweight misses the limit?
There is no single automatic outcome described for every miss. UFC lists possible consequences including purse forfeiture, a catchweight agreement, or cancellation. The applicable limit, how far over it a fighter is, the bout agreement, and the event commission’s procedures all matter. A purse deduction should not be assumed in every case.

Official event listings show how recorded weights relate to the bout type, but an example does not establish a universal penalty or outcome.
| Event example | Reported weights | Context |
|---|---|---|
| Erin Blanchfield vs. Maycee Barber, 2025 | Blanchfield: 125 pounds; Barber: 126.5 pounds | Non-title bout; Barber’s listed weight was above the 126-pound allowance. UFC’s listing does not, by itself, make this a rule for how every miss is handled. UFC official weigh-in results |
| Rose Namajunas vs. Tracy Cortez, 2024 | Namajunas: 124.75 pounds; Cortez: 126 pounds | Non-title bout; Cortez’s listed weight was at the non-title maximum. UFC official weigh-in results |
| Priscila Cachoeira vs. Gillian Robertson, 2021 | Cachoeira: 129 pounds | UFC reported that Cachoeira forfeited 30 percent of her purse to Robertson. This is one event’s reported consequence, not a default penalty schedule. UFC official weigh-in report |
Which weigh-in details vary by event?
UFC’s general explainer does not establish one universal protocol for weigh-in clothing, scale calibration, borderline readings, or retries at every venue. Those procedural details should be checked against the documentation for the specific event and its athletic commission.
