Free coach tool
Boxing weight difference and match comparison checker
Enter both dates of birth, the proposed bout date, current weights, and bout totals. BoutCheck derives each age category and produces a transparent comparison using the selected governing-body profile.
This simplified tool does not approve a bout. Always use the current governing-body rules, exact dates of birth, boxer records, medical status, safeguarding requirements, officials, and coach judgement.
What this calculator cannot decide
A numeric comparison cannot assess style, development, recent form, time away, stoppages, medical fitness, or readiness. Rules also vary by governing body, contest type, championship, and season.
