Boxing weight classes are divisions that categorize fighters based on their weight to ensure fair competition. These classes help match opponents of similar size and strength, which is crucial for safety and fairness in the sport. The main weight classes include heavyweight, cruiserweight, light heavyweight, super middleweight, middleweight, super welterweight, welterweight, super lightweight, lightweight, super featherweight, featherweight, super bantamweight, bantamweight, super flyweight, and flyweight. Each weight class has a specific weight limit, and boxers must weigh in before a fight to confirm they are within their designated class. If a fighter exceeds the limit, they may be disqualified or forced to move up to a higher class. This system allows for a structured and organized approach to matchmaking in professional boxing.
