Kickboxing weight classes are weight classes that pertain to the sport of kickboxing.
Organizations will often adopt their own rules for weight limits, causing ambiguity in the sport regarding how a weight class should be defined. For a variety of reasons (largely historical), weight classes of the same name can be of vastly different weights. For example, a boxing middleweight weighs up to 72 kg (160 lb), an ISKA middleweight upper limit is 75 kg (165 lb), and a K-1 middleweight upper limit is 70 kg (154 lb).
This table gives names and limits recognised by the widely regarded sanctioning bodies and promotions in professional kickboxing, Muay Thai and shoot boxing.
