History of Boxing Weight Category

When boxing was in its infancy in the eighteenth century, there was no boxing weight category which resulted in a lot of size mismatches and one-sided fight.

This was very dangerous to a boxer with smaller size and it was not satisfying to the viewing public.

To address this issue, the National Sporting Club of London in 1909 required all national titles to have standard weight classes in order to be recognized.

This was also stated in the Walker Law in 1920, which established the New York State Athletic Commission.

In professional boxing, sanctioning bodies during the 1960’s narrowed those weight categories resulting to more weight classes that allow fighters to transfer from one weight category to another with ease.

The name of this new weight division is not standardized.
