If you just want to play for recreational purposes, the right table tennis room size is one that can hold a table tennis table, which should be 9 feet long and 5 feet wide (2.74m x 1.525m). The ideal space is actually 8.5m x 4.12m (or 28 feet x 13 feet 6 inches).
Playing Area Used in Tournaments
These dimensions are the minimum; in most cases, organizers use bigger rooms. For world championship events and the Olympics, the minimum space is 14m x 7m (46 feet x 23 feet). Space for table tennis in national tournaments is a bit smaller at 12m x 6m (equal to 40 feet x 20 feet).
The dimensions for national league games are 10m x 5m (or 33 feet x 16 feet 6 inches). The same table tennis room size is used in representative matches.
In local tournaments and leagues, the average size is 9m x 5m (30 feet x 16 feet 6 inches). For leisure play, the minimum size is 8.5m x 4.12m (28 feet x 13 feet 6 inches).
Without adequate lighting, the quality of game play will deteriorate. General lighting is usually not good enough. The light to be used for the game should account for the entire playing surface. This is usually gauged at the table surface height. In recreational play, the light should be 300 lux (10 ft / 3m above the floor).
If the table tennis room size is designed for local tourneys, the light has to be 500 lux (10 ft / 3m above the floor). For the representative and national league games, it is also 500 lux.
In some national tournaments, the lux is 750 to 1,000. This is also true for international tournaments. This can be 10 ft /3 m or 13 ft / 4 m above the floor. For the Olympics, it is 1,000 lux at 16 ft 6 in (5 m) above the floor.
The Floor or Floor Covering
The best floor type is wooden semi-sprung. The floor covering should fit and match the table tennis room size, but other factors need to be considered too. The floor has to be non-slip. The surface must be level.
The floor must be able to support the weight of the players and table. The surface cannot be reflective as it can distract the players and fans. Flooring with a reddish hue is most often used. Carpeted and concrete floors should never be used when playing the game.
Other Factors to Consider
Most players like to play in temperatures of 15-20 degrees C although some prefer higher temperatures. Whatever the room dimensions, ventilation should be a priority. Condensation will lead to slippery surfaces. It will also cause the ball to slide from the racket. Be certain the air conditioning doesn’t have air currents that affect the trajectory of the ball.
The table tennis room size needed by casual players is not that much. As long as you have the proper flooring, setting up the table and equipment will be easy.
