Five free boxing tools covering weight classes, fight scoring, calorie burn, session planning, and reach advantage calculation. Covers amateur (Olympic) and professional formats.
Boxing basics
Professional boxing uses 10-point must scoring per round — the winner of each round receives 10 points, the loser 9 (or fewer for knockdowns). Three judges score independently; the fighter with the majority of round wins across all judges wins a decision. Amateur boxing (Olympic format) uses a computer-based scoring system counting clean punches landed to the head and body by gloved knuckles.
Boxing rounds are 3 minutes for professionals (2 minutes for some amateur formats) with 1-minute rest between rounds. Professional championship bouts are 12 rounds; non-championship main events typically 10 rounds.

What are the professional boxing weight classes?
From lightest to heaviest: Minimumweight (105lb), Light Flyweight (108lb), Flyweight (112lb), Super Flyweight (115lb), Bantamweight (118lb), Super Bantamweight (122lb), Featherweight (126lb), Super Featherweight (130lb), Lightweight (135lb), Super Lightweight (140lb), Welterweight (147lb), Super Welterweight (154lb), Middleweight (160lb), Super Middleweight (168lb), Light Heavyweight (175lb), Cruiserweight (200lb), Heavyweight (unlimited). The four major sanctioning bodies (WBC, WBA, IBF, WBO) all recognise these divisions.
How is a boxing fight scored?
Three judges sit at ringside and independently score each round 10-9 to the dominant fighter (10-8 for a knockdown round, 10-7 for multiple knockdowns). At the end of the fight, each judge totals their scores. The fighter with the majority of round wins on the judges' cards wins by decision. A unanimous decision means all three judges agree; a split decision means two judges favour one fighter and one the other; a majority decision means two judges favour one fighter and one scores it a draw.
How many calories does boxing burn per hour?
Sparring and pad work burn approximately 500–700 calories per hour for a 75kg boxer. Heavy bag work and circuit training burn 400–600 calories per hour. The calorie burn is high because boxing demands both aerobic endurance (sustaining output across rounds) and anaerobic power (explosive combinations). Shadow boxing at light intensity burns approximately 300–400 calories per hour.
