A full-size table tennis table is 2.74 metres long, or 9 feet, measured along its playing surface.
The International Table Tennis Federation specifies a rectangular playing surface 2.74 metres long and 1.525 metres wide. The tabletop must stand 76 centimetres above the floor, creating the familiar proportions used in international competition.
The length is sometimes confused with the table’s width, which is 1.525 metres. Another common mix-up is confusing the playing surface with the table’s supporting frame or legs; the official measurement concerns the marked playing surface itself.
These dimensions apply to singles and doubles alike. Unlike some sports, table tennis does not use a narrower competition table for singles matches. The same full-size table is used, with singles players simply occupying different areas of the surface.
