Boxing weight classes: The boxing weight classes simply explained


In professional as well as olympic boxing there are different weight classes. Why are there these different boxing weight classes and how are they called, we will answer in the following lines. In addition, you will know exactly which weight class you are currently in.

Weight classes ensure that the fight is as balanced as possible.

Why are there different boxing weight classes?

The different boxing weight classes exist primarily to allow the fight to be as balanced as possible in terms of weight. It is obvious that a boxer who boxes in a weight class up to 60 kg has less punch force than an athlete who competes in a weight class over 91 kg.

With the different weight classes, the advantage of weight or punch force is minimized. Many boxers therefore try to reduce their weight so that they are classified in a lower weight class, for example, to build up a reach advantage. This is also known as “making weight”.

There are up to eleven different weight classes in amateur boxing.

How many boxing weight classes are there?

Boxing weight classes can be divided by gender as well as by professional or olympic boxer. Thus, there are different weight classes.

In olympic boxing alone, there are up to eleven different weight classes – for men and women. These range from half flyweight to super heavyweight.

Most boxers try to lose as much weight as possible just before the weigh-in in order to be classified in a lower weight class.
