UFC Weight Classes Explained: Everything You Need to Know about them

UFC Weight Classes have undergone a lot of changes over the years. When UFC first started out, it did not even have weight classes and this projected Mixed Martial Arts as a wild and unsafe sport.

However, as the sport evolved and when UFC came under the supervision of Athletics commissions, there was a change in this story.

What are the weight classes in the UFC?

As of writing, UFC follows the weight limits which are designated by the Unified Rules of Mixed Martial Arts. While the Unified Rules of MMA has limits for fourteen weight classes, UFC currently only has 9 weight classes in the promotion.

Atomweight Class in MMA:

The Atomweight class is something that is not defined in the Unified Rules of MMA. However, it is used by many promotions exclusively for Women’s Fights. It is, however, something that varies with respect to promotions. You can see the Atomweight limits from major promotions below.

  • The Invicta FC's atomweight limits between 96 and 105 lb (43.5 to 47.7 kg)

Weight Classes in ONE Championship

While most of the promotions follow weight classes with respect to the Unified Rules of MMA, ONE Championship has a different rule set in which weight limits are based on the walking weight of fighters rather than their pre-fight weight.

In fact, ONE Championship introduced the rule to improve fighter safety and to avoid weight-cutting by dehydration. ONE championship’s policy on weight mandated that athletes are monitored in their training camps, and have urine-specific gravity tests to ensure they are hydrated up to three hours ahead of their fights.

You can see the weight classes in ONE Championship below.

  • Atomweight: 115 lbs (52 KG)
