Frequently asked questions

What's the heaviest weight class?

Heavyweight in professional boxing has no upper limit. In amateur boxing, 'Super Heavyweight' covers above 91kg. The heavyweight division is the highest-profile in professional boxing.

Can a fighter change weight class?

Yes — many fighters compete across two or more weight classes in their career, either moving up as they mature, or cutting weight to compete in a lighter class. Moving up is more common later in a career.
