Padel is a racquet sport. It is different from the sport known in the US and Canada as paddle tennis. Padel is typically played in doubles on an enclosed court roughly 25% smaller than the size of a tennis court. Scoring is the same as normal tennis and the balls used are similar but with a little less pressure. The main differences are that the court has walls and the balls can be played off them in a similar way as in the game of squash and that solid, stringless bats are used. The height of the ball being served must be at or below the waist level. Padel is not to be confused with platform tennis, a winter and summer sport typically played at country clubs in the US and Canada, with courts heated from below to eliminate snow and water. The court, rules and styles of play are very different.
