UFC Weight Classes Explained And Which Ones Fighters Dread the Most

Size matters in the UFC to make sure fights are fair and competitive. The right weight class can make or break a fighter’s career. Some divisions have razor-thin gaps, while others jump by nearly 60 pounds! A few extra pounds can mean heavier punches or a serious endurance drop.

Let’s break down every UFC weight class and the surprising differences between them.
