The average size of a roller skating rink is 18,000 square.feet includes a skating surface of about 10,000 square feet, about 70 feet by 150 feet.his depends on capacity of the rink and how many people you can have on the rink in one go. I would normally say 200 pairs would be sufficient however for a smaller rink you â¦ could have less. Regards Korby.
