Mixed martial arts weight classes

Mixed martial arts weight classes are weight classes that pertain to the sport of mixed martial arts.

Organizations will often adopt their own rules for weight limits, causing ambiguity in the sport regarding how a weight class should be defined. For a variety of reasons (largely historical), weight classes of the same name can be of vastly different weights. For example, a boxing Middleweight weighs up to 160 pounds, a UFC Middleweight is 185, and a Pride middleweight was 205.

Weight classes in the United States

In 2000, the Unified Rules of Mixed Martial Arts were codified by the New Jersey State Athletic Commission – working with the California State Athletic Commission, who had worked extensively on regulation, but its sanctioning of MMA was not implemented due to state governmental issues surrounding the budgeting process. California officially sanctioned MMA on December 28 2005, using the ruleset it helped devise five years previously.

Since then, to create uniformity in the United States, many state athletic commissions have assimilated these rules for mixed martial arts into their existing unarmed combat competition rules and statutes. For a promotion to hold mixed martial arts events in a state-sanctioned venue, the promotion must abide by the state athletic commission's body of rules for weight limits.

Weight classes under the Unified Rules

The Nevada State Athletic Commission has designated limits for nine different weight classes in mixed martial arts. Fighters must be weighed in lbs:
Weight class name Upper limit in lbs Equivalent in kg
Flyweight 125 lb 57 kg
Bantamweight 135 lb 61 kg
Featherweight 145 lb 66 kg
Lightweight 155 lb 70 kg
Welterweight 170 lb 77 kg
Middleweight 185 lb 84 kg
Light Heavyweight 205 lb 93 kg
Heavyweight 265 lb 120 kg
Super Heavyweight No upper weight limit

Prior to state sanctioning, weight classes were not mandatory since the competitions were held without the approval of the athletic commissions. For instance, the Ultimate Fighting Championship introduced two weight classes at UFC 12: heavyweight, which grouped competitors above 200 lb (91 kg), and lightweight, which grouped competitors under 200 lb.

Weight divisions would undergo many changes in the coming years, but the ability of promotions to autonomously decide their own weight classes would eventually disappear after athletic commissions began supervising mixed martial arts.

Proposed revision

In July 2008 a change to the existing classes was proposed by the Association of Boxing Commissions to have a total of 14 classes, the proposals have been rejected by the biggest organisation, the UFC and several state athletic commissions.
Weight class name Upper limit in lbs Equivalent in kg
Flyweight 105 lb 47.6 kg
Super Flyweight 115 lb 52.2 kg
Bantamweight 125 lb 56.7 kg
Super Bantamweight 135 lb 61.2 kg
Featherweight 145 lb 65.8 kg
Lightweight 155 lb 70.3 kg
Super Lightweight 165 lb 74.8 kg
Welterweight 175 lb 79.4 kg
Super Welterweight 185 lb 83.9 kg
Middleweight 195 lb 88.5 kg

Super Heavyweight No upper weight limit

Non-codified states and exceptions

In the following states, MMA is legal but is not regulated by a local commission: Alabama, Alaska, Hawaii, Massachusetts, Minnesota, Montana, South Dakota, and Wyoming.

The most notable of these states is Hawaii, whose lack of codified restrictions on mixed martial arts allows promotions to set their weight limits as they see fit. Hawaii's Rumble on the Rock has a welterweight champion at the unique weight of 175 lb (79.5 kg).

Promotions that hold events on Indian reservations are exempt from any restrictions, as they are outside the jurisdiction of state commissions.

Weight classes in Japan

With no state or government laws regarding weight class restrictions, Japanese organizations are free to schedule bouts with little regard for weight differential. However, due to the increasingly competitive nature of the sport, weight is often seen as an unfair advantage over a smaller competitor; therefore, weight limits have been set by the promotions themselves. These limits differ from organization to organization. Japan uses the metric system.

DREAM

DREAM's weight categories go by similar guidelines as the Unified Rules, differing only by a few pounds.
