The boxing ring is actually not a circle shaped enclosure but a square shaped one. The term “ring” is generally considered to be an old adage and can be linked to ancient times when similar combat sports were conducted within an enclosed circle or ring. The usage of the term has continued to this day, even though the modern boxing ring is a square enclosure and each side is anywhere between 16 and 25 feet. There are many professional boxing organizations and each one has its own side length of the boxing ring. The entire boxing ring is placed on an elevated platform.
This platform is raised three to four feet from ground level, again depending upon the boxing organization. Each corner of the boxing ring contains a pole and these poles are roughly five feet in length. The length of the pole is same for all organizations and so it allows standardization of the spacing of ropes that are secured to the poles. There are four ropes that form the outer perimeter of the boxing ring and these ropes are placed at a height of 18, 30, 42 and 50 inches from the base of the elevated platform. The ropes are roughly 1 inch in thickness.

Boxing rings range from 4.9 M x 4.9 M ( 16x 16 ft ) to 6.1 M x 6.1 M ( 25 x 25 ft ) (measured inside the line of the ropes).
They are constructed as a raised platform of between 910 mm and 1220 mm above the ground level.
There must be a minimal 2000 mm clear zone around the outside of the ring.
The floor of the ring is made of a flat and level 20 – 25 mm thick plywood flooring over a robust steel frame, covered by 20 – 25 mm of foam and a final canvas cover. This floor must extend at least 460 mm outside the ropes line.
