UFC women’s flyweight has a 125-pound limit for title fights and a 126-pound maximum for non-title bouts. Official weigh-ins are generally held the day before the event, but exact procedures and the consequences of missing weight can depend on the event’s athletic commission and bout agreement.
What is the UFC women’s flyweight weight limit?
The limit depends on whether the bout is for a title. UFC’s published weight-class explainer sets the women’s flyweight championship limit at 125 pounds and allows a one-pound allowance for non-title bouts.

| Bout type | Maximum weight | What that means |
|---|---|---|
| Title bout | 125 pounds | A fighter must weigh 125 pounds or less. |
| Non-title bout | 126 pounds | The one-pound allowance applies; 126 pounds is the maximum, not the championship limit. |
So a title contender weighing 125.5 pounds is over the title limit, even though the same scale reading is below the stated non-title maximum. UFC explains the distinction in its weight-class and weigh-in overview.

UFC describes official weigh-ins as generally taking place the day before fight night, between 9 a.m. and 11 a.m. local time. This is a general schedule, not a guaranteed window for every event.
#1 Best Overall
UFC says an additional hour to make weight may be granted depending on the overseeing commission and how much weight a fighter has left to lose. Its overview does not set a universal retry procedure for every venue. For a particular card, the relevant state or local athletic commission’s event rules are the better source for procedural details.
What happens if a flyweight misses weight?
A missed weight does not automatically produce one standard outcome. UFC lists a purse forfeiture, a catchweight agreement, or cancellation as possible consequences. The applicable limit is the first question: 126 pounds for a non-title bout or 125 pounds for a title bout. The event’s commission and bout agreement also matter.
- Purse forfeiture: A fighter may give up part of their purse under the terms applied to that event.
- Catchweight: The bout may proceed at an agreed weight rather than the scheduled division limit.
- Cancellation: The bout may be called off.
These are possible outcomes, not a fixed penalty ladder. UFC’s 2021 report on Priscila Cachoeira said she weighed 129 pounds and forfeited 30 percent of her purse to Gillian Robertson; that is one event-specific example, not a universal penalty schedule. See UFC’s official weigh-in results.
What do UFC weigh-in examples show?
Official event listings illustrate the difference between a recorded scale weight and the applicable allowance. They do not establish that every miss will have the same consequence.
| Bout | Reported weights | Context |
|---|---|---|
| Erin Blanchfield vs. Maycee Barber | Blanchfield: 125 pounds; Barber: 126.5 pounds | UFC listed these weights for their 2025 non-title bout; Barber’s recorded weight was above the stated 126-pound non-title maximum. |
| Rose Namajunas vs. Tracy Cortez | Namajunas: 124.75 pounds; Cortez: 126 pounds | UFC listed these weights for their 2024 bout; 126 pounds is the non-title maximum under UFC’s stated allowance. |

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Who sets and oversees the rules?
UFC says its bouts adhere to the Unified Rules of MMA, a framework intended to support consistent professional competition across athletic commissions. UFC’s overview reports that the Association of Boxing Commissions unanimously adopted the Unified Rules on July 30, 2009.
The event’s state athletic commission oversees the bout, and UFC notes that the commission can affect procedures such as whether extra time is allowed after an initial weigh-in miss. UFC’s general overview does not establish universal rules for clothing, scale calibration, borderline readings, or retries at every venue. UFC’s Unified Rules overview provides the framework; event-specific procedural questions should be checked against the relevant commission’s documentation.
