Understanding UFC Weight Classes | Top Weight Categories of UFC in 2024

The Ultimate Fighting Championship (UFC) introduced the concept of weight classes long ago. A weight class means a fighter must weigh under or around a particular weight before the official fight in the ring.

Currently, the UFC has 12 different weight divisions, 4 for women and 8 for men. What is the role of UFC weight classes? Weight divisions are necessary to ensure fair competition between opponents. In this way, the fighter who wins solely depends on his talent and bravery rather than having a great weight advantage.

If the athlete doesn’t fulfill the weight criteria, the result will be canceling the fight with mutual consent or agreeing to have a non-weight competition with the opponent. Let’s explore the UFC weight classes more.

History of Weight Classes

Initially, there was no concept of weight classes in UFC. Most fighters fought with huge weight differences, leading to fighter safety concerns. 

The most famous example of this situation can be seen when Emmanuel Yarborough, who was 6’8, weighing 616 lbs, fought with Keith Hackney, who was 5’11 and weighed 200 lbs.

Later, in 1997, some changes were made. The weight classes concept was also introduced to ensure safety and fairness in the tournament. The first weight classes introduced were lightweight (155 lbs) and heavyweight (over 205 lbs). 

Features of Weight Classes

Different weight divisions have fighters with various fighting styles and skills.

In strawweight and flyweight, lighter fighters are included. They are short in stature yet focus on technical moves with quick hits.

Moreover, in heavier classes, fighters depend more on toughness and power, focusing on solid punches.

Advantages of Weight Classes

The UFC weight classes have immense importance

  • To ensure fighters compete against opponents of similar size
  • To have a balanced yet fair competition
  • Boosting fan engagement to appreciate the fighting style and physique of fighters in each weight division.
  • To reduce the chances of being injured by big-size competitors.

It is unfair to compete against opponents with huge weight differences. Weight classes are so important in mixed martial arts (MMA).

Disadvantages of Weight Classes

While having UFC weight classes has advantages, it also holds some disadvantages.

  • Weight cutting in the UFC is a big problem. Fighters cut weight to fight in lighter divisions, which badly affects their health.
  • Fighters who cannot fulfill the weight class criteria must forfeit 20% of their fight money to an opponent.
  • The other reason is some weight classes have better fighters than others.


UFC weight classes are significant in providing fair competition in the sport. Undeniably, there are challenges like weight cutting, lower weight of fighters, and strict rules in weight classes. Every weight class has unique fighters showcasing their abilities.

Having weight classes provides insights for fans to support their favorite fighter and appreciate each competitor’s fight style. In the future, UFC may have more strict rules regarding weight-cutting, motivating fighters to maintain weight. Also checkout the list of top 10 Youngest UFC Champions.
