The Official Rule
- Any boxer weighing more than 200 lbs (90.7 kg) is classified as a heavyweight.
- There is no upper weight limit — a 200 lb fighter and a 300 lb fighter can legally compete in the same division.
- This 200 lb threshold has been in place since 2004, when major sanctioning bodies raised the cruiserweight limit to 200 lbs.
- Before 2004, the heavyweight minimum was 190 lbs in most jurisdictions.

Historical Context
- In the 19th century, heavyweight champions often weighed under 200 lbs. John L. Sullivan — the first widely recognised heavyweight champion under Queensberry Rules — weighed around 200 lbs when in shape.
- From the Corbett era through to Floyd Patterson (roughly 1892–1960), the average title-winning weight was around 195 lbs.
- From Sonny Liston to Larry Holmes (1960s–1980s), the average title-winning weight rose to approximately 208 lbs.
- Since the 1990s it became common for top heavyweights to enter at 220–250+ lbs.
- The current range among active top heavyweights is roughly 215–265 lbs, making it the most physically diverse division in boxing.
