Does anyone know the regulation height of a pool table? USPBA?

Question

I'm looking for the distance from the floor to the top of the cushion.

Answer 1

According to the World Pool-Billiard Association, which provides the equipment specifications for many sanctioned events in the industry, the table bed (that is the playing surface, not the rails of the table):

Shall be between 29 ¼ inches [74.295 cm] and 31 inches [78.74 cm].

Of course, commercial manufacturers do not have to comply with WPA standards, but what the governing body of international play says is pretty authoritative on the subject.
