Paddle tennis is a racket sport that has been adapted from tennis and has been played for over a century. It is also known as platform tennis or POP tennis. The game is played with a solid perforated paddle, as opposed to a strung racquet, and a lower pressure tennis ball. The court is smaller than a tennis court, has no doubles lanes, and the net is lower. The court measures 50 feet (15.24m) baseline-to-baseline and 20 feet (6.09m) across, with the service line 3 feet (0.91m) in from the baseline. The net is placed at a height of 31 inches (0.78m) . Paddle tennis courts are constructed of the same materials as tennis courts, or can also be placed on hard beach sand.

Paddle tennis is always played in doubles, and the scoring system is the same as in tennis. The server must serve underhand, and a second serve is allowed only in the event of a net ball that lands in bounds, as in tennis. The ball can bounce off any wall, but it can only hit the turf once before being returned. Points can be scored when the ball bounces twice in the competitors’ field. The paddles used in paddle tennis are made of a composite material without strings, and the hitting surface is perforated.

Padel is a similar sport to paddle tennis, typically played in doubles on an enclosed court slightly smaller than a doubles tennis court. Although padel shares the same scoring system as tennis, the rules, strokes, and technique are different. The balls used are similar but with a little less pressure. The court has a floor made of concrete, plastic, or artificial grass, and it is designed similarly to a tennis court, only smaller - measuring 10x20 m, with a 0.88m (34.6 inches) high net in the middle. The court is surrounded by 4-meter high walls made of glass or brick, or a fence when outside.

In summary, paddle tennis is a racket sport that is similar to tennis but has some key differences. It is played with a solid perforated paddle and a lower pressure tennis ball on a smaller court with no doubles lanes and a lower net. The scoring system is the same as in tennis, and the server must serve underhand. Padel is a similar sport to paddle tennis, but it is played on an enclosed court with walls and has different rules, strokes, and technique.
