UFC's Weight Classes: Everything You Need to Know
Trying to keep up with all of the weight classes in the UFC can quickly become overwhelming.
In this guide, we will explain what weight classes are, how many there are, and the future of weight classes.
How Many Weight Classes Are in the UFC?
There are a total of 12 weight classes in the UFC, with the men's divisions having 8, and the women's division having 4.
|Weight Class||Weight||Men/Women or Both|
|Strawweight||115 lbs||Women only|
|Light Heavyweight||205 lbs||Men|
|Heavyweight||Up to 265 lbs||Men|
Why Are There Weight Classes?
Levels the Playing Field
Weight classes are extremely important to MMA as it allows two fighters of similar sizes to fight each other.
In the early days, it was 'open weight' and there were constant instances where a fighter was massively outsized.
This led to either very fast finishing fights or boring fights as the person who was outsized would play it safe, and the massively larger person was too slow to get to him.
One of the early problems however was that there weren't enough fighters to be able to fill up weight classes. As the talent started to pour into MMA, it made sense to transition to weight classes.
Legitimizes the Sport
A big part of a sport being able to grow into the national spotlight is attracting new fans. When new fans see a 300 lbs guy fighting a 150 lbs guy, it doesn't exactly scream 'real sport'.
In fact, in the early days, Senator John McCain called it 'Human Cockfighting'.
As weight classes were implemented (along with uniforms), the talent pool started to fill up, and MMA was able to transition into the national spotlight.
What Happens if a Fighter Comes Overweight
Non Title Bout
If a fighter is overweight during a weigh-in, their opponent has the option to not proceed with the scheduled bout, or proceed but take a percentage of the opponent's purse (money).
The opponent also has to agree to that %.
The average percentage that you'll see is in the 20% - 30% range.
So if a fighter is being paid $100,000 for the fight and he comes in overweight, he can be giving up $20,000 to $30,000 of his money to his opponent.
The same rules apply as a nontitle bout with one major difference. The fighter who comes in overweight cannot fight for the actual title.
He can still fight, but if he wins he does not win the belt.
An example of this was Deiveson Figuereido vs Joseph Benavidez 1.
Figueiredo won the fight through a TKO but was ineligible to win the belt. He still received the win in his record.
When Did the UFC Get Weight Classes?
Heavyweight Division is Born
The heavyweight division is the oldest division that was implemented in 1997.
This division is one of the pillars of MMA due to the fans being able to watch giant-sized athletes fight.
Due to the amount of power that heavyweights possess, they're a must-see event as fights often result in knockouts.
The heavyweight champion is commonly referred to as 'The Baddest Man on the Planet'.
The welterweight and light heavyweight divisions were introduced shortly after in 1997 - 1998.
In 2000, the UFC adopted the 'Unified Rules of MMA' created by the New Jersey State Athletic Control Board. This adoption paved the way for multiple weight classes and helped legitimize MMA as a sport.
The UFC fighters still compete under these unified rules today.
Future of UFC Weight Classes
There are still improvements that can be made as far as weight classes.
Gaps in Weight: There are big gaps in multiple weight classes. When you take into consideration the lengths that fighters go through to cut weight to have a size advantage of a few lbs, 15-20 lbs to move up or down in a weight class is insane
Lightweight to Welterweight = 15 lbs.
Welterweight to Middleweight = 15 lbs.
Middleweight to Light Heavyweight = 20 lbs.
Overflowed Division: The premier division of the UFC, the 155 lbs lightweight division comes to mind. That division is so stacked that there are great fighters that can't even break into the top 10 despite having the talent to do so. The division is that stacked.
Tweeners: As more talent enters the MMA world, there will be more 'tweeners' now than ever. A tweener is someone who is best suited for a weight class in between two current weight classes.
However, that weight class currently doesn't exist so they're left to choose whether to bulk up, or cut and dehydrate down.
UFC Double Champs
Now that you've gotten a crash course on weight classes and why they're so important to the sport, you'll understand what a giant accomplishment being a double champion is.
There have only been a handful of UFC fighters who have become double champions, and they've each won it in spectacular fashion
Conor McGregor: Featherweight and Lightweight Champion
McGregor put on arguably the best performance of his career by toying with Eddie Alvarez and knocking him out in round 2.
Daniel Cormier: Light Heavyweight and Heavyweight Champion
DC moved up in weight and knocked out Stipe Miocic in under 5 minutes.
Amanda Nunes: Bantamweight and Featherweight Champion
Nunes also moved up in weight and took on who was at the time known as the most dominant female fighter Cris Cyborg and knocked her out cold in under 1 minute of a chaotic fight.
Henry Cejudo: Flyweight and Bantamweight Champion
Cejudo moved up in weight and overcame some early adversity (a ton of leg kicks) to knock out Marlon Moraes in the 3rd round.
