Pickleball is a paddle sport which combines elements of badminton, tennis, and table tennis.
The sport is played on a court with the same dimensions as a doubles badminton court. The net is similar to a tennis net, but is mounted two inches lower. The game is played with a hard paddle and a polymer smaller version of a wiffle ball. Pickleball is similar to tennis, but with differences. A pickleball ball typically moves at one-third of the average speed of a tennis ball and the court is just under one-third of the total area of a tennis court.
