UFC Weight Classes (Divisions) in both lbs and kg!

Like all martial arts and combat sports, the UFC has several weight categories that are called divisions.

As we know, the main purpose of weight categories is to equalize the battlefield and enable relatively similar opponents to face each other without anyone having a clear-cut advantage over the other.

UFC weight classes (divisions):

• Heavyweight: 265 lb (120.2 kg)
• Light Heavyweight: 205 lb (102.1 kg)
• Middleweight: 185 lb (83.9 kg)
• Welterweight: 170 lb (77.1 kg)
• Lightweight: 155 lb (70.3 kg)
• Featherweight: 145 lb (65.8 kg)
• Bantamweight: 135 lb (61.2 kg)
• Flyweight: 125 lb (56.7 kg)
• Strawweight: 115 lb (52.5 kg)

In this article, I am going to present to you the UFC weight divisions, as well as all the champions for each of them. There’s not a lot of them – 8 for men and 4 for women – but that does not make it less interesting.

What Are the Different UFC Weight Classes?

In order to understand the UFC weight divisions, we have to understand how weight categories in MMA generally work. Since it would be of no use for us to describe all the categories, I shall present them to you in one table, which is pretty self-explanatory:

UFC Men’s Weight Classes (Divisions)

Now, as you will soon see, the UFC doesn’t have a division for each of the weight categories as they are presented in the table.

The UFC only has eight divisions and they correspond to eight of the before mentioned categories.

The oldest one is the Heavyweight Division, founded back in 1997.

The Light Heavyweight and Welterweight Divisions soon followed in December 1997 and 1998, respectively, with the Lightweight and Middleweight divisions being introduced in 2001.

The most recent divisions are the Bantamweight and Featherweight, introduced in 2010, and the Flyweight Division, introduced in 2012.

So, historically, the first-ever weight division UFC champion was Mark Coleman, who won the Heavyweight belt back in 1997.

UFC Women’s Weight Classes (Divisions)

The competition format for women is both newer in date and a lot smaller. Women only participate in four categories, with three of them being the same as the men’s and one being specifically for women.

The oldest among them is the Women’s Bantamweight Division, which got its first champion at the end of 2012.

The end of 2014 saw the establishment of the Women’s Strawweight Division, while the remaining two divisions – Women’s Featherweight and Women’s Flyweight – started in 2017.

So, the first female UFC champion in any category was American Ronda Rousey, who won the Women’s Bantamweight title in December 2012. 

UFC Tournaments and the Superfight Championship

Throughout its existence, the UFC has also held numerous openweight tournaments.

Unlike the more-known divisions, openweight tournaments do not have any weight limits, which means that everyone can participate and that there can be a substantial difference in the physique of the fighters, something we’ve talked about at the beginning of this article.

Certainly, that could lead to unfair situations, but if you know the rules beforehand and accept them as they are, then the issue is a bit clearer. 

UFC has had two openweight competitions, with just one being active. The now defunct Superfight Championship was held only twice, in 1995 and 1996, was envisioned as a tournament that would determine the ultimate UFC champion.

Ken Shamrock won the first edition, while his challenger from 1995, Dan Severn, became the tournament’s second and final winner. 

The UFC tournaments are held on an irregular basis since 1999 (until then, they’ve been an annual event, sometimes held more than once a year), from which moment only two tournaments have been held – one in 2003 and the most recent one in 2012.

These tournaments were initially openweight, but have been associated with weight divisions since the UFC 12 edition in 1997.

Of course, I bring you a list of all of them and the winners:

And that concludes our short analysis of UFC’s weight divisions and categories.

What About Weight Cutting in the UFC?

As the subject of weight cutting in the UFC (and other combat sports) is complex, I have written an article where I explain how UFC fighters cut weight in depth.
