There are strict regulations in place to ensure that fighters are able to get to their optimum weight safely, and the implementation of weight classes in the UFC attempts to ensure that everyone competes on an even playing field.

Here’s everything you need to know about the weight classes in the UFC and what their limits are in both pounds and kilos.

There are sometimes Catchweight bouts that take place on a UFC card, but these are extremely rare and are usually implemented as a last-minute change to a fight if there were injuries or issues beforehand.

If a fighter comes in for the official weigh-in over the allocated maximum weight, then their opponent has the option to choose whether or not the fight will still go ahead.

Under usual circumstances, if the opposing fighter does agree to continue on with a Catchweight contest, then they will receive 20% of their competitor’s purse (the amount they get paid to fight in the octagon).
