List of old boxing classes (8 class era) and weights. Is there too much nowadays?

The boxing class system has changed several times throughout history.

In the old boxing world, the number of weight classes was eight, fewer than in modern times, and was divided into basic weight classes.

Below are some common classes in the early 20th century.


Old boxing class (8 class era) and weight list


Traditional boxing classes (early 20th century)


  • Flyweight : The lightest weight class. At that time, it weighed less than 112 pounds (approximately 50.8 kg).
  • Bantamweight : 118 pounds or less.
  • Featherweight : 126 pounds (approximately 57.2 kg) or less.
  • Lightweight : 135 pounds (approximately 61.2 kg) or less.
  • Welterweight : 147 pounds or less.
  • Middleweight : 160 pounds or less.
  • Light Heavyweight : This weight class varies by season, but generally weighs 175 pounds or less.
  • Heavyweight : Any weight could compete and there was no upper limit.


These weight classes have existed since the earliest days of organized boxing and form the basis of boxing’s history.

Throughout the 20th century, new weight classes were added and the weight limits of existing weight classes were adjusted, resulting in today’s diverse weight classes.

For example, super featherweight (under 130 pounds), super lightweight (under 140 pounds), super welterweight (under 154 pounds), super middleweight (under 168 pounds), and cruiserweight (now also known as bridgerweight). A number of new “super” or intermediate classes were created, including those under or near 200 pounds.

This allows more athletes to compete in weight classes appropriate to their weight.



8 When did the class system begin and end?

Boxing’s class system has its roots in the 19th century, when the sport began to be organized, but the eight-division system was only formally established in the early 20th century.

This eight-class system included the following classes introduced earlier:

  1. flyweight
  2. bantamweight
  3. featherweight
  4. lightweight
  5. welterweight
  6. middleweight
  7. light heavyweight
  8. heavyweight

There are slight differences between organizations and regions as to when this system officially began, but it is generally said that it was widely recognized in the 1920s.

At the time, these weight classes were intended to provide a fair framework for boxers to compete and reduce the disadvantages of weight differences.

Boxing’s weight class system evolved over time, with more weight classes being introduced, especially after the 1950s when television broadcasts began to become popular. This was done as a way to create more title fights and provide viewers with more attractive matches.

As a result, new weight classes such as super featherweight, super welterweight, and super middleweight were added, increasing the number of weight classes to 17 to date.

Although it is difficult to define the exact year in which the eight-class system ended, it can be said that its form gradually changed from the 1950s to the 1960s, when new classes began to be gradually introduced.

The reasons behind this change were to commercialize the sport, create new opportunities to increase fan interest, and provide a more fragmented playing field for athletes.


The evolution of boxing’s class system is deeply connected to the development of the sport and its social and economic background.

The increase in weight classes gave more boxers the opportunity to become champions, helping to popularize the sport.

The weight class system plays an important role in ensuring fair competition and protecting the health of athletes.



What changes have occurred with the increase in the number of weight classes in boxing?

The increase in the number of weight classes in boxing brought about several important changes to the sport. These changes are impacting the sport itself, athletes, fans and the commercial side of the sport.


  1. Increased Opportunities for Athletes : The increase in the number of weight classes has given more boxers the chance to win world titles. Athletes of different weights and physical characteristics can maximize their potential by competing in the weight class that best suits them.

  2. Improved competitiveness : Due to the division of weight classes, the disadvantages due to weight differences have been reduced, and technique and strategy have become more important factors. This has increased the competitiveness of the matches, making for fairer and more heated battles.

  3. Commercial benefits : More weight classes mean more title fights, increasing revenue opportunities for promoters and broadcasters. This helped popularize and commercialize boxing, solidifying its status as a major media event.

  4. Expanded fan interest : A variety of title fights in different weight classes made it more appealing to fans and provided an opportunity to become familiar with a wider range of fighters and styles. This meant that athletes from different regions and cultures around the world were in the spotlight, helping to increase boxing’s international popularity.

  5. Movement between weight classes : With the increase in the number of weight classes, it has become common for athletes to compete in multiple weight classes throughout their careers. This created new feats such as “multi-division champion” and further enriched the athlete’s legacy.

  6. Segmentation and specialization of the sport : With the increase in classes, training and strategies also became more specialized. Athletes and trainers were required to prepare for specific weight classes of competitors, leading to innovations in technique and conditioning methods.


The increase in the number of weight classes has made boxing a more dynamic and diverse sport, contributing significantly to its development.

At the same time, it has been pointed out that the increase in ranks will create complications and that the value of titles will be diluted, and the impact is multifaceted.



Are there too many weight classes in boxing?

Opinions are divided as to whether there are too many weight classes in boxing.

To understand this issue, we need to consider both the advantages and disadvantages of having a large number of classes.




1.Athlete safety and health

Segregating weight classes reduces competition between athletes with large weight differences, protecting the health and safety of athletes.

This provides a more level playing field and allows athletes to compete in weight classes appropriate to their weight.


2. Increased opportunities

Having more weight classes provides players with more opportunities to win championships and titles.

This leads to increased motivation and promotes the development of the sport as a whole.


3. Diversity and strategy

The large number of weight classes allows players of various body types and styles to play an active role. This increases the variety of strategies and techniques that make boxing a more attractive sport.





1. Fan confusion

Too many weight classes can make it difficult for fans to follow the fighters and champions in each weight class.

Especially in boxing, where there are multiple organizations, situations can arise where there are multiple champions in the same weight class, causing confusion for fans.


2. Dilution of the value of champions

As the ranks increase, the number of champions will naturally increase as well. This can dilute the value of championship titles and make it harder for them to earn the honor and respect they once did.


3. Disparity between sports

There can be large differences in the number of competitors and attention depending on the class, and there can be a disparity in prize money and opportunities between popular and less popular classes.


The debate over the class system boils down to the fundamental question of whether the health and safety of athletes should be given top priority, and how to balance the attractiveness and competitiveness of the sport.

We need to carefully consider the impact of reducing the number of weight classes and find the best solution in the interests of players, fans and the sport as a whole.
