A 4 x 8 (1.2 x 2.4 m) slate pool table weighs between 950 and 1,100 lbs (430 kg and 498 kg), depending on the structure of the table and thickness of the slate. While the industry standard for the thickness of a single slate table is one inch (2.54 cm), some manufacturers make their products slightly thicker or less thick. Also, when purchasing a pool table, take into account the table structure and weight of added materials.
