Table tennis can be played in a variety of spaces but ideal facilities include a dedicated room between 8.5m x 4.12m for recreational play and 14m x 7m for international competitions. Proper lighting between 300-1000 lux, a non-slip floor, appropriate temperature and ventilation are also important for playing conditions. The space should allow for singles play or multiple side-by-side tables with barriers between courts.

2. is, and can be, played in a
wide variety of environments which is an
advantage because it is easily set up but also a
disadvantage as it is easily packed away
therefore becoming invisible.
Often the sport is made to put up with sub-
standard facilities such as poor lighting,
unsuitable floor covering or inappropriate wall
colouring.

3. Compared to most other sports, the
size requirements for table tennis are
relatively small. Therefore you can play
the game almost anywhere.
Ideally, table tennis should be played
in a dedicated space with appropriate
facilities permanently available, however,
that's not always possible.
The main factor in determining what
table tennis room size you'll need is the
standard / level of competition being
played.
So let's take a look at the various
room sizes required for different
standards / levels of competition.

4. These are the minimum size dimensions you'll need for the playing
area, based on the standard of 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)

5. 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.

6. Uniform lighting over the whole of the playing area is essential.
The minimum light intensity over the whole of the playing surface (measured at
the table surface height) and the clear height from the floor to the light should
be as follows:
 World Championships & Olympic Games
1,000 lux
5m (16 feet 6 inches) above the floor
 Other International and National tournaments
750 - 1,000 lux
4m (13 feet) above the floor
 National league / Representative matches
500 lux
3m (10 feet) above the floor
 Local league / Local tournaments
500 lux
3m (10 feet) above the floor
 Recreational play and coaching
300 lux
3m (10 feet) above the floor

7.  paramount importance
 #1 priority
 non-slip
 smooth and level
 able to support the weight of the table tennis table and the players
 good contrast between the table top surface and the surrounding
areas, both for the benefit of the players and the spectators; non-
reflective
Wooden semi-sprung floors provide the best surface while solid
concrete and carpeted floors are totally unsuitable.
All the top international table tennis tournaments now use specialist
sports flooring such as Taraflex® made by French company Gerflor.
The reddish color of this flooring, together with blue tables,
provides a fantastic setting for table tennis.

8.  The ideal room temperature is 15-20°C with a
relative humidity of 40-50%.
 adequate ventilation; any condensation will make
the floor slippery and will cause the ball to slide
off the racket if you're using reverse rubber.
 If there are any air conditioning units, you'll also
need to ensure that they don't cause any air
currents which will deflect the flight of the ball.
 Spectators' comfort
 playing conditions take priority

9.  Important because the players need a good
contrast between the floor, table and wall colors.
 non-reflective and painted with a dark color up
to a height of at least 2.5m (8 feet).
 walls should be painted a lighter color above
2.5m
 covered up windows or other external light
sources

10.  If you're using a table tennis room size that
can accommodate multiple tables, they should
be arranged side by side rather than long
ways.
 you should also leave a gangway between the
playing areas. This will give you access to each
court without the need to disturb the other
courts.

11.  Barriers
◦ useful to stop the ball from straying too far
and minimize interruptions from other tables.
◦ must be collapsible rather than solid, so that
they won't harm any player who runs into
them
◦ 1.5m (5 feet) long and 75cm (2 feet 6 inches)
high and should completely enclose the
playing area
