The official dimensions of a table tennis table, as specified by the International Table Tennis Federation (ITTF), are as follows:
- **Length**: 2.74 meters (9 feet)
- **Width**: 1.525 meters (5 feet)
- **Height**: 0.76 meters (2 feet 6 inches) from the floor to the top of the playing surface
The playing surface must be rectangular and made of any material that yields a uniform bounce of about 23 centimeters (9 inches) when a standard ball is dropped from a height of 30 centimeters (11.8 inches).
The table is divided into two equal halves by a vertical net running parallel to the end lines. The net assembly, including the net, its suspension, and the supporting posts, should be 15.25 centimeters (6 inches) high. The net should extend 15.25 centimeters (6 inches) beyond the side lines of the table.
The surface of the table, known as the playing surface, should be uniformly dark-colored and matte, with a white line 2 centimeters (0.75 inches) wide along each edge. The longer lines are called side lines, and the shorter lines are called end lines. Additionally, a white center line, 3 millimeters (0.12 inches) wide, runs parallel to the side lines, dividing each half of the table into two equal courts for doubles play.
These dimensions and specifications ensure consistency and fairness in the sport, allowing players to compete under standardized conditions worldwide.
