Rankings are based on the Glicko-2 rating system. The rating shown is a conservative estimate calculated from the rating and its uncertainty. Uncertainty decreases with more matches and increases during periods of inactivity. To be ranked, boxers must have at least 5 total matches and at least one match within the last 12 months. Note: Ratings reflect relative strength within each weight class and may not be comparable across weight classes.

The ranking system is currently in beta. The algorithm and parameters may be updated, which could change how ratings are calculated.
