Types of Classes in Boxing: Weight and Class Guide

Have you ever wondered why boxers are always divided into weight classes before they finally step into the ring and face each other? This question often arises, especially for those of you who are new to boxing or simply watch it for entertainment.

This article will comprehensively discuss the various classes in boxing based on weight and weight class. The discussion is structured in a relaxed yet informative style, making it easy to understand for anyone curious about the official structure and rules behind boxing.

This fight illustrates the application of classes in boxing which ensures both boxers compete with equal strength and weight.

Why Are There Classes in Boxing?

Boxing classes aren't just fancy labels on the scoreboard, but a crucial system that keeps matches fair and safe. These divisions ensure each boxer competes against opponents of relatively equal physical condition.

Simply put, boxing weight classes are the classifications of boxers based on their weight before they enter the ring. The goal is to prevent matches from devolving into one-sided physical confrontations between larger and smaller fighters.

Without weight classification, fights can be lopsided and endanger athletes' safety. A difference of just a few kilograms can significantly impact punching power, arm reach, and endurance.

This class system applies at all levels, from amateur boxing to international professional boxing. Besides ensuring fairness, the class divisions also reflect the different fighting styles in each category.

Heavyweight Classification in Professional Boxing

1. Flyweight to Heavyweight

In professional boxing, there are many weight classes, each with its own specific weight limits. These can vary slightly between world boxing bodies, but they generally follow the same structure from lightest to heaviest.

You've probably heard of classes like Lightweight and Heavyweight when watching boxing . These are the official names for the weight classes, arranged sequentially so that boxers of similar weights can compete against each other.

This weight class ranking is designed to maintain a consistent weight difference between categories, allowing for a fair comparison of boxers' technique, speed, and endurance. This system applies to both professional and amateur levels, although there are slight differences in weight ranges.

2. Differences between Professional and Amateur Classes

While professional boxing has up to 17 weight classes, amateur boxing (e.g., school or national competitions) typically has fewer weight classes and simpler weight ranges. The primary focus is on the development and safety of young athletes.

For example, at the amateur level in Indonesia, you can find boxing classes ranging from 46 kg to 91 kg, depending on category and gender. This is designed to allow students and beginners to compete fairly without having to undergo extreme weight cuts.

This distinction is important to understand because an athlete may be in a certain weight class while in the amateur arena, but once he becomes a professional, he may need to adjust his weight according to the new weight class range.
