What are the different weight classes in boxing, and how are they determined?

Boxing has various weight classes, which are used to ensure fair competition between fighters of similar size and weight. Some common weight classes include heavyweight, light heavyweight, middleweight, welterweight, lightweight, featherweight, and bantamweight. The specific weight limits for each class may vary depending on the sanctioning body and governing organization. Fighters typically weigh in before the match to ensure they meet the requirements for their chosen weight class. Competing in the appropriate weight class is crucial for boxers to maintain a competitive edge and avoid potential disadvantages due to size or weight differences.
