THE LAWS OF TABLE TENNIS

The Table

1.         The upper surface of the table, known as the playing surface, shall be rectangular, 2.74m long and 1.525m wide, and shall lie in a horizontal plane 76cm above the floor.

2.         The playing surface shall not include the vertical sides of the tabletop.

3.         The playing surface may be of any material and shall yield a uniform bounce of about 23cm when a standard ball is dropped on to it from a height of 30cm.

4.         The playing surface shall be uniformly  dark coloured and  matt, but  with a
white side line, 2cm wide, along each 2.74m edge and a white end line, 2cm wide, along each 1.525m edge.

5.         The playing  surface shall be divided  into  2 equal courts by a  vertical net
running parallel with the end lines, and shall be continuous over the whole
area of each court.

6.         For doubles, each court shall be divided into 2 equal half-courts by a white
centre line, 3mm wide, running parallel with the side lines; the centre line shall be regarded as part of each right half-court.

The Net Assembly

1.         The net assembly shall consist of the net, its suspension and the supporting posts, including the clamps attaching them to the table.

2.         The net shall be suspended by a cord attached at each end to an upright post 15.25cm high, the outside limits of the post being 15.25cm outside the side line.

3.         The top of the net, along its whole length, shall be 15.25cm above the playing surface.

4.         The bottom of the net, along its whole length, shall be as close as possible to the playing surface and the ends of the net shall be as close as possible to the supporting posts.

The Ball

1.         The ball shall be spherical, with a diameter of 40mm.

2.         The ball shall weigh 2.7g.

3.         The ball shall be made of celluloid or similar plastics material and shall be
white or orange, and matt.

The Racket

1.         The racket may be of any size, shape or weight but the blade shall be flat and rigid.

2.         At least 85% of the blade by thickness shall be of natural wood; an adhesive layer within the blade may be reinforced with fibrous material such as carbon fibre, glass fibre or compressed paper, but shall not be thicker than 7.5% of the total thickness or 0.35mm, whichever is the smaller.

3.         A  side of  the blade used for  striking  the ball shall be covered  with either
ordinary  pimpled  rubber, with pimples outwards  having a total  thickness
including adhesive of not more than 2.0mm, or sandwich rubber, with pimples inwards or outwards, having a total thickness including adhesive of not more than 4.0mm.

4.         Ordinary pimpled rubber is a single layer  of non-cellular rubber, natural or
synthetic,  with pimples evenly  distributed over  its  surface at a density of
not less than 10 per cm² and not more than 30 per cm².

5.         Sandwich rubber is a  single  layer of cellular rubber  covered with a single
outer layer of ordinary pimpled rubber, the thickness of the pimpled rubber
not being more than 2.0mm.

6.         The covering  material shall  extend up to but not  beyond  the limits of the
blade, except that the part nearest the handle and gripped by the fingers may be left uncovered or covered with any material.

7.         The blade, any layer within the blade and any layer of covering material or
adhesive on a side used for striking the ball shall be continuous and of even thickness.

8.         The  surface of the covering  material on a side of the blade, or of a side of
the blade if it is left uncovered, shall be matt, bright red on one side and black on the other.

9.         The racket covering shall be used  without  any physical, chemical or other
treatment.

10.       Slight  deviations from continuity of surface or  uniformity  of colour due to
accidental  damage  or  wear  may  be  allowed  provided  that they do not
significantly change the characteristics of the surface.

11.       Before the start of a match and  whenever he changes his racket  during a
match a player shall show his opponent and the umpire the racket he is about to use and shall allow them to examine it.

Definitions

1.         A rally is the period during which the ball is in play.

2.         The ball is in play from the last moment at which it is stationary on the palm of the free hand before being intentionally projected in service until the rally is decided as a let or a point.

3.         A let is a rally of which the result is not scored.

4.         A point is a rally of which the result is scored.

5.         The racket hand is the hand carrying the racket.

6.         The free hand is the hand not carrying the racket; the free arm is the arm of the free hand.

7.         A player strikes the ball if he touches it in play with his racket, held in the
hand, or with his racket hand below the wrist.

8.         A player obstructs the ball if he, or anything he wears or carries, touches it in play when it is above or traveling towards the playing surface, not having touched his court since last being struck by his opponent.

9.         The server is the player due to strike the ball first in a rally.

10.       The receiver is the player due to strike the ball second in a rally.

11.       The umpire is the person appointed to control a match.

12.       The assistant umpire is the person appointed to assist the umpire with certain decisions.

13.       Anything that a player wears or carries includes anything that he was wearing or carrying, other than the ball, at the start of the rally.

14.       The ball shall be regarded as passing over or around the net assembly if it
passes anywhere other than between the net and the net post or between the net and the playing surface.

15.       The end line shall be regarded as extending indefinitely in both directions.

The Service

1.         Service shall start with the ball resting freely on the open palm of the server's stationary free hand.

2.         The  server  shall  then  project the  ball  near  vertically  upwards,  without
imparting spin, so that  it rises at  least 16cm  after leaving the palm of the free hand and then falls without touching anything before being struck.

3.         As the ball is falling the server shall strike it so that it touches first his court
and then, after passing over or around the net assembly, touches directly the receiver's court; in doubles, the ball shall touch successively the right half court of server and receiver.

4.         From the  start of  service until it is struck, the ball shall be above  the level
of the playing surface and behind the server's end line, and it shall not be hidden from the receiver by the server or his doubles partner or by anything they wear or carry.

5.         As soon as the ball has been projected, the server’s free arm and hand shall be removed from the space between the ball and the net. The space between the ball and the net is defined by the ball, the net and its indefinite upward extension.

6.         It is the responsibility of the player to serve so that the umpire or the assistant umpire can be satisfied that he complies with the requirements of the Laws, and either may decide that a service is incorrect.

7.         If either the umpire or the assistant umpire is not sure about the legality of
a service he may, on the first occasion in a match, interrupt play and warn
the  server; but  any  subsequent  service  by  that  player  or  his  doubles
partner which is not clearly legal shall be considered incorrect.

8.         Exceptionally, the umpire may relax the requirements for a correct service
where he is satisfied that compliance is prevented by physical disability.

The Return

The ball, having been served or returned, shall be struck so that it passes over or around the net assembly and touches the opponent's court, either directly or after touching the net assembly.

The Order of Play

1.         In singles, the server shall first make a service, the receiver shall then make a return and thereafter server and receiver alternately shall each make a return.

2.         In doubles, the server shall first make a service, the receiver shall then make a return, the partner of the server shall then make a return, the partner of the receiver shall then make a return and thereafter each player in turn in that sequence shall make a return.

3.         When two players who are in wheelchairs due to a physical disability are a
pair playing doubles, the server shall first make a service, the receiver shall then make a return but thereafter either player of the disabled pair may make returns. However, no part of a player’s wheelchair shall protrude beyond the imaginary extension of the centre line of the table. If it does, the umpire shall award the point to the opposing pair.

A Let

1.         The rally shall be a let :

a.         if in service the ball, in passing over or around the net  assembly, touches
it, provided the service is otherwise correct or the ball is obstructed by the
receiver or his partner;

provided  that  neither  the  receiver  nor his partner  attempts  to strike the

c.         if  failure  to make a service or a  return  or otherwise  to  comply  with  the
Laws is due to a disturbance outside the control of the player;

d.         if play is interrupted by the umpire or assistant umpire;

c.         in  singles  leaves the  receiver’s  court  after  touching  it  by  either  of  its
sidelines.

A Match

A match shall consist of the best of any odd number of games.

The order of Serving, Receiving and Ends

Out of order of Serving, Receiving or Ends

1.         If a player serves or receives out of turn, play shall be interrupted by the umpire as
            soon as the error is discovered and shall resume with those players serving and 
            receiving who should be server and receiver respectively at the score that
            has been reached, according to the sequence established at the beginning of the
            match and, in doubles, to the order of serving chosen by the pair having the right to serve
            first in the game during which the error is discovered.

2.         If the players have not changed ends when they should have done so, play shall be interrupted by the umpire as soon as the error is discovered and shall resume with the players at the ends at which they should be at the score that has been reached, according to the sequence established at the beginning of the match.

3.         In any circumstances, all points scored before the discovery of an error shall be reckoned.
