Why is a boxing ring square?

The origin of the ring was to prevent interference from outsiders! In the 1800's fans would punch fighters (see the movie "far and away" with tom cruise and nicole kidman for a portayal of this).

The square ring allowed for better viewing and safe distances.

According to The Encyclopedia of Boxing, by Gilbert Odd, the term "boxing ring" goes back to bare-knuckle days.

Spectators held a circle of ropes around the fighters, but they were always crowding in on the action. Eventually, they used stakes to hold the ropes, forming a square.

yeah it does contradicts right? RING = Circle then why square

Because boxers used to fight in a circle drawn on the floor, called the ring. This name stuck On even after the boxing ring became a square

It's been like that for more then a century. It be like saying why are boobs round. Why can't they be flat.
