The billiard equipment used in
pool tournaments has to meet the standards set by the World
Pool-Billiards Assassination (WPA). Of course, these
standards do not apply on home billiard games, but a pool
tournament can be ruled if the billiard equipment used in it did not
meet the standards detailed here. The WPA equipment
specifications refer to billiard tables, balls and cue
sticks.
For example, the bed of the billiard table has to be at
least 29.25 inches high but not higher than 31 inches. In
order to avoid injuries, the billiard table cannot have
sharp edges or any other materials that can even damage the
players' clothes.
The slates in a standardized billiard table must be a least
1-inch thick. In pool tournaments, the tables are required
to have a set of slates with three equal sized pieces with a
wooden frame, which must be at least 0.75 inch.
Billiard tables can come in different sizes, but the playing
surface of the table has to be rectangular. In 9 foot
billiard tables, the playing surface should be 100 X 50
inches, without the cushions; in 8 foot table the playing
surface is limited to the sizes of 92 X 46 inches.
The rail of the billiard table has to be at least 4 inches
wide but cannot be wider than 7.5 inches; the rubber
cushions are included. The rubber cushions have to be in a
shape of a triangular and to be located about 2 inches from
the outer edge of the feather strip.
The pocket jaws must be made of rubber facings at least as
thick as 1/16 inches but no more than 1/14 inches. According
to the WPA recommendations, the rubber facings should be as
thick and as hard as possible.
The sizes of the pocket openings in billiard tables also
known as the mouth, also have standardized measurements: the
corner pocket mouth is required to size between 4.25 inches
to 4.625 inches and the size of the side pocket mouth can
ranger from 5 to 5.125 inches.
The pocket liners and boots should be covered by either
plastic, rubber or leather as long as the material won't
stain neither the billiard balls nor the cue sticks. In any
case, the upper part of the inner wall must to be designed
in such a manner that when a ball hits the pocket liner
wall, the ball will be directed downwards.
The cloth that covers the billiard table has to contain at
least 85% of wool fabric and no more than 15% nylon and it
cannot pill or fluff. The World Pool-Billiard Assassination
permits only billiard table clothes in the colors of
yellow-green, blue-green or electric blue.
The WPA billiard equipemnt rules requires that the set of standardized billiard balls have to be made of cast phenolic
resin plastic. They should be measured 2.25 inches and weigh
between 5.5 and 6 oz. Polishing and waxing the billiard
balls is not allowed; the balls can be cleaned only with a
towel or a clean cloth.
A set of billiard balls has to consist of one cue ball,
colored white and a group of fifteen colored object balls
numbered 1 through 15. The numbers have to be visible, so
they must be printed twice and black on a white background.
According to the official billiard equipment rules, the cue sticks used in pool
tournaments must be at least 40 inches long and to weigh no
more than 25 oz. The cue tip cannot be wider than 14 mm.
Additionally, the cue tip must be made of an especially
suitable leather or any other material, which would
naturally fit in with the line of the shaft end and will not
be able to damage the billiard balls.
