An adhesive layer within the blade may be reinforced with fibrous material such as carbon fiber, glass fiber, or compressed paper but shall not be thicker than 7.5% of the total thickness or 0.35 mm, whichever is the smaller.Ĥ.3 A side of the blade used for striking the ball shall be covered with either ordinary pimpled rubber with pimples outward having a total thickness including adhesive of not more than 2 mm. The ball shall weigh 2.7 gm.ģ.2 The ball shall be made of celluloid or similar plastic material and shall be white or orange and matte.Ĥ.1 The racquet may be of any size, shape, or weight but the blade shall be flat and rigid.Ĥ.2 At least 85% of the blade by thickness shall be of natural wood. 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.ģ.1 The ball shall be spherical, with a diameter of 40 mm. outside the side lines.Ģ.4 The net, with its suspension, along its whole length, shall be 15.25 cm.

Permanent marking of the center line shall not invalidate the table for singles play. (1/8 in.) wide, running parallel with the side lines, termed the center line. (9 ft.) edges or sides shall be termed side lines.ġ.4 For doubles, the playing surface shall be divided into halves by a white line 3 mm. (5 ft.) edges or ends shall be termed end lines, and they shall be regarded as extending indefinitely in both directions.ġ.3.2 The lines along the 274 cm. (3/4 inch) wide along each edge.ġ.3.1 The lines along the 152.5 cm. (12 in.) above the surface.ġ.3 The playing surface shall be dark colored and matt, with a white line 2 cm.

It shall be supported so that its upper surface, termed the playing surface, shall lie in a horizontal plane 76 cm.
