Playing area
These are the minimum size dimensions you'll need for the playing area (this
means the area required for one table tennis table), based on the standard
of table tennis competition being played...
International Events, World Championships & Olympic Games
14m x 7m (46 feet x 23 feet)
National tournaments
12m x 6m (40 feet x 20 feet)
National league / Representative matches
10m x 5m (33 feet x 16 feet 6 inches)
Local league / Local tournaments
9m x 5m (30 feet x 16 feet 6 inches)
Recreational play and coaching
8.5m x 4.12m (28 feet x 13 feet 6 inches)
Of course, if you want to play table tennis at home, you could use any space
that will accommodate a table tennis table (9 feet long and 5 feet wide - 2
.74m x 1.525m).
However, any area smaller than the recommended size of 8.5m x 4.12m will
mean that you'll be restricted in either the type of strokes you can use and
/or your style of play.
But remember, the idea is to HAVE FUN.
