What is the official width of a full-size table tennis table?

The official width of a full-size table tennis table is 1.525 metres.

International regulations specify a playing surface measuring 2.74 metres long and 1.525 metres wide. The tabletop is 76 centimetres above the floor, while a net divides it into two equal courts. These dimensions apply to standard competition tables used under International Table Tennis Federation rules.

The width is often remembered incorrectly because many recreational tables are smaller or fold into compact formats. A full-size table is wide enough to support the angles and side-to-side movement required in singles and doubles play.

The table’s length, width, and height are separate measurements. The 1.525-metre figure identifies the playing surface from one long side to the other; it is not the net length or the table’s overall folded footprint.
