A professional boxing match typically lasts up to 12 rounds , with each round lasting 3 minutes for men and 2 minutes for women. There is a 1-minute rest period between rounds. Thus, a full professional men's match can last up to 36 minutes of fighting time plus 11 minutes of rest (making about 47 minutes total including rest). Amateur matches usually have fewer rounds, often 3 rounds of 2 or 3 minutes each. If a knockout or stoppage occurs, the match ends immediately regardless of the round. Historically, matches could be longer, with up to 15 rounds, but safety considerations have reduced the top limit to 12 rounds since the 1980s. Non-title professional fights may have fewer rounds, often between 4 and 10 rounds. Women's professional rounds are generally 2 minutes each.
