A pool table varies in many different sizes and can come with different sized balls such as American pool balls which are 60mm and BlackBall pool balls which are 55mm. A
billiard table or
billiards table is a bounded
table on which billiards-type games (
cue sports) are played. In the modern era, all billiards tables (whether for
carom billiards,
pool or
snooker) provide a flat surface usually made of quarried
slate, that is covered with cloth and surrounded by vulcanized rubber cushions, with the whole elevated above the floor. An obsolete term is
billiard board, used in the 16th and 17th centuries.
