UFC weigh in scale

Nobody would’ve guessed that the old no holds barred UFC tournaments would transform into a legitimate sport. The UFC has done a lot of work to make MMA one of the most popular sports in the world.

How many divisions are there in the UFC? Today, there are currently 12 different divisions in the UFC. Let’s explain how they got here and go through the history of the UFC weight classes. 

Going from when the UFC decided to make weight divisions and what they look like today. We’ll also explain the different bouts that are held within the UFC weight classes.

History of UFC Weight Classes

The early days of the UFC 

As you probably know, there were no weight classes in the early days of the UFC. It was an open weight one night fight tournament. Fighters of various sizes fought each other in this format that lasted a few years.

The UFC transitions to make MMA a sport 

As the UFC continued to run shows, they realized with the no holds barred format, they would stay relatively underground. The no holds barred gimmick could not sustain the company going into the future.

So, this would start the transition of the UFC turning MMA into a legitimate sport. They would need to add rules for the sport and of course bright classes.

The first UFC classes

The UFC would first start implementing weight classes in 1997 at the UFC 12 event. They would first introduce two different divisions for the fight tournaments of the event.

Those were the heavyweight division and the lightweight division. Not the same heavyweight and lightweight divisions as we know them now.

Their early heavyweight division was placed at 200lbs(91kgs) and below that was the lightweight at 199lbs(90kgs) and below.

Once the UFC introduced these weight classes, they saw immediate improvements to the product. Fights were more fair at the same weights and the fights were better.

Lightweight renamed to middleweight

The UFC would rename the lightweight division to the middleweight division shortly after it was introduced. This was because they had plans to introduce more weight classes that were below that weight class.

The UFC Lightweight division

The new lightweight division would be introduced at UFC 16, which was set at 170lbs and below.  It would then be rebranded as the welterweight division as the UFC added the 155lb lightweight division at UFC 30. (2001)

This division would be discontinued for a while, but brought back in 2006.

 The UFC/WEC Merger 

It would be 4 years until the UFC added more weight divisions. Zuffa would merge the WEC into the UFC and with it came more weight divisions in 2010. Adding  the UFC featherweight and bantamweight divisions.

UFC weight classes for women are introduced

When Zuffa bought Strikeforce in 2012, they inherited their first women’s division, which was the bantamweight division. The success of the first women’s division would lead to the addition of more women’s divisions over the next few years.

First was the strawweight division, then the women’s featherweight division, and the last being the women’s flyweight division.

The UFC Flyweight division is introduced

The men’s flyweight division would be introduced in September of 2012. Right before the introduction of the women’s bantamweight division.

The difference between title bouts and non title bouts 

When you watch a UFC event you’ll notice different types of bouts between each of the UFC weight classes. The matches are either non title bouts or title bouts.

Title bouts are at the top of the card, while the non title bouts make up the rest of the night of fights. Aside from title bouts being for a belt, there is one other specific difference between them. 

That is the one pound rule. In non title bouts, you don’t have to weigh in at exactly a certain weight of below it. 

If you’re fighting at middleweight, you can come into the fight at 186 with no problem. But if it were a title bout, you would have to weigh in at 185lbs or below.

Rules for missing weight and penalties

There is a certain protocol within the UFC weight classes if a fighter misses weight. Before any penalties are handed down, the fighter has one hour to cut the remaining weight.

If they fail to cut the remaining weight in the hour given, they will be penalized. They will be deducted a percentage of their purse if the other fighter agrees to still fight them. 

Missing weight for a title bout has even worse consequences. Failing to make weight for a title bout means that the bout will no longer be for a title.

Instead it’ll be just a 5 round main event bout, where no title match bonus will be given out.(At least to the fighter that missed weight.)

Possible new weight divisions

There are always rumors of possible new UFC weight classes that may get added into the future. Here are some of those possible new UFC weight classes and Joe Rogan’s weight class idea.

UFC Women’s Atomweight division

For a few years, the UFC has been floating the idea of making another women’s division. A atomweight that would be at 105lbs(47.6kg).

Quite a few fighters like Michelle Waterson have been vocal about the addition of this division. Feeling that many fighters that walk around at 130lbs+ that cut to strawweight gives them an unfair advantage.

Fighters that walk around between 115-120lbs would be on an even playing field. Nothing is concrete about this division being added in the future, but you never know.

UFC 165lb division

One UFC weight class that a lot of lightweight and welterweight fighters have been pitching for is a 165lb(75kg) division. There have been two specific reasons this weight has been constantly brought up.

The big one is that 165lb is a nice buffer zone between lightweight and welterweight. Great for fighters that are too small for welterweight, but have a hard time cutting to lightweight.

Many fighters that fight from both weight classes liked the idea, so they could fight against each other. Getting the opportunity to fight in more than one weight class would be profitable for them.

After the success of the Diaz vs Masvidal bout at 165lbs, many fighters and fans were vocal about adding it permanently. Unfortunately there are no plans to make a 165lb division as of now.

Joe Rogan’s idea

If you listen to the JRE podcast, then you’ve heard Joe Rogan talk about his idea for UFC weight divisions. Rogan doesn’t just want one more weight division added, but numerous divisions.

He wants the UFC weight classes to look more like boxing weight classes. In that format, there would be a weight division at every 10lbs.

Joe believes this would give more fighters the opportunity to fight and the chance to hold multiple titles. Of course, this is just Joe’s idea and probably nothing will come from it.

The future of UFC weight classes

As of now, there are currently 12 UFC weight classes within the promotion. The sport of MMA is always growing and evolving and there are more fighters than ever.

We will no doubt see new UFC weight classes get added in the future. It will be a win for the fighters and us fans, who will get to see more great fights.
