If you are here, it probably is for two reasons; the first one: are you going to start combat sports? Second one: you begin a combat sport.
It is expected that beginners ask this question because they still have not experience fighting.
If you are just curious more about the weight classes in martial arts, it is also the best place for you. So let’s go.
Why are there weight classes in combat sports? The weight classes in combat were made because the fighters must have the possibility to fight against an opponent of the same size, in the way that both fighters have the same amount of force or almost. Nowadays, the weight classes are very different from years ago, the modern fighter use, the weight-cutting that consists of drastic types of diet, and dehydration,to enter the weight classes that they are competing in.
The weight-in is not the same for all the combat sports, there are many differences in the weight category, and this is what we are going to talk about in the following part of the article, and much more, so let’s go.
How have weight classes born in combat sports?
Still, in 1900, there wasn’t a standard weight class for combat sport; these were doing damage to the fighter that was with a weight class less, but also to the watcher, because the fight was wholly mismatching and, the fighter with more weight was almost always destroying his opponent.
The first signal for correct implementation of the weight-in on combat sports happened thanks to boxing. They were on in 1909 by the National Sporting Club of London, and those in the 1920 Walker Law that established the New York State Athletic Commission (NYSAC).
A significant change in the weight classes also happened in 1960, with the WBA; the WBA introduces eight different weight-classes; thus, the fighters can move more easily from a class to another.
In general, the fighter after passing the age, they start from a lower weight class and end up their carrier, with much higher weigh classes, this is due to the difficult to maintain the weight after the advanced age, more in particular maintain the diet and dehydration for weight cutting.
Now it’s time to go more in-depth and see the different weight classes category for the main combat sports:

As soon the MMA became more famous, more attention was given, particularly thanks to the exponential growth of the UFC (ultimate fighting championship).
In 2000, the Unified Rules of Mixed Martial Arts were codified by the New Jersey State Athletic Commission, with the mission to create uniformity on the rules
The Unified Rules designate limits for fourteen different weight classes in mixed martial arts

| Featherweight | 145 lb (65.8 kg) | 146 lb (66.2 kg) |
| Lightweight | 155 lb (70.3 kg) | 156 lb (70.8 kg) |
| Super lightweight | 165 lb (74.8 kg) | 166 lb (75.3 kg) |
| Welterweight | 170 lb (77.1 kg) | 171 lb (77.6 kg) |
| Super welterweight | 175 lb (79.4 kg) | 176 lb (79.8 kg) |
| Middleweight | 185 lb (83.9 kg) | 186 lb (84.4 kg) |
