The Welterweight division in mixed martial arts is one of the sport's most competitive weight classes. Positioned directly between the Lightweight (155 lbs) and Middleweight (185 lbs) divisions, it acts as a focal point for athletes combining speed, endurance, and elite grappling or striking power.
Division Weight Limit: 170 lbs (77.1 kg)
Non-Title Allowance Limit: 171 lbs (77.6 kg)
Next Division Down: Lightweight (155 lbs)
Next Division Up: Middleweight (185 lbs)
Welterweight Division Rules & Allowances
Under the Unified Rules of Mixed Martial Arts, the official weight limit for the Welterweight class is exactly 170 pounds (77.1 kg).
Like other non-championship divisions, a one-pound allowance is granted for non-title matches. This means a fighter can weigh up to 171 lbs during the official weigh-ins and still compete without penalty. However, for a Welterweight championship title fight (whether undisputed or interim), the fighters must weigh exactly 170.0 lbs or below.
