According to iSport, the size of a boxing ring varies based on the type of competition and the relevant governing body in each case. Typical ring sizes range from 16 square feet to 24 square feet.
The sizes of boxing rings may differ even within a particular type or level of boxing. There are no set ring dimensions at the professional level, though governing bodies at this level, including USA boxing, do have strict guidelines. Olympic boxing ring dimensions are based on the guidelines provided by the Amateur International Boxing Association. The size stipulated for international competition in this context is 20 square feet.
