Professional wrestling weight classes

WWE, the largest professional wrestling promotion both nationally and internationally, has a reserved championship exclusively for wrestlers under the "Cruiserweight" category. Historically, WWE has had a number of championships that were only competed by lighter wrestlers such as the WWE Light Heavyweight Championship which became defunct in 2001. Conversely, WWE's so-called "Heavyweight" championships aren't exclusive to heavyweight performers (240 lbs and above) as it has been won by light wrestlers such as Rey Mysterio and AJ Styles.

While some of the smaller, independent wrestling promotions use weight classes, most of the larger promotions do not. Even if weight classes are used, they are usually not enforced due to the scripted nature of professional wrestling. In March 2013, Total Nonstop Action Wrestling (TNA) imposed a 230 pounds (100 kg) weight limit for wrestlers competing in the X Division for the TNA X Division Championship. In October 2013, however, TNA wrestler Samoa Joe, billed at 280 pounds (130 kg), competed in an X Division Championship bout at TNA's Bound for Glory pay-per-view. Rather, it's more common for wrestling promotions to create a secondary championship to be competed for by smaller wrestlers. This championship, depending upon the promotion, is usually named Cruiserweight, Light Heavyweight or Junior Heavyweight. In some sports, most notably boxing since it has a large number of weight classes, these three names represent different separate weight classes. In professional wrestling the upper weight limit of these championships varied and are often not strictly enforced, depending upon the desires of company management, but usually ranged from a maximum of 215 pounds to 230 pounds depending upon the promotion. Throughout the years, practically all of such championships have been retired due to the wrestling promotion closing down or losing interest. The oldest of these championships still active in the United States is the NWA World Junior Heavyweight Championship. Created in 1945, the title is also recognized and frequently defended in other promotions outside of the United States.

No other professional wrestling promotions have made such an extensive use of weight classes as some located in Mexico. The lucha libre style is highly prominent in Mexico and makes extensive use of high spots and a fast, sometimes frantically so, pace that suits physically smaller wrestlers. As a result, most of the top professional wrestling stars in Mexico are lighter than those in many American promotions. Whereas the few American promotions and governing bodies, such as the National Wrestling Alliance, have what would be termed a Cruiserweight, Light Heavyweight or Junior Heavyweight division, several Mexican wrestling promotions have multiple weight classes.

As with Mexico, non-heavyweight wrestling championships have risen to prominence in a number of Japanese wrestling promotions. Unlike Mexico, however, and more in line with most promotions in the United States, most Japanese wrestling companies generally have a secondary singles and, in some cases, a tag team championship geared to the Cruiserweight/Junior Heavyweight/Light Heavyweight weight division rather than multiple weight divisions.

The 1947 Admiral-Lord Mountevans rules set out seven weight divisions with maximum weight limits and called for champions to be crowned of each limit: Lightweight: 11st (154 lb or ~70 kg), Welterweight 11st 11 lb (165 lb or ~75 kg), Middleweight 12st 8 lb (176 lb or ~80 kg), Heavy Middleweight 13st 5 lb (187 lb or ~85 kg), Light Heavyweight 14st 2 lb (198 lb or ~90 kg), Mid-Heavyweight 14st 13 lb (209 lb or ~95 kg) and Heavyweight for all weights upwards of 15st (210 lb or ~95 kg).[3][4]

An earlier system of weight classes with different levels and more divisions existed under the 1930 All-In rules.[5] Many "American style"/"New School" promotions follow the example of modern US promotions of having a Cruiserweight/Junior Heavyweight/etc division alongside primarily Heavyweight competition.
