The ideal ceiling height to accommodate a pool table in a room is 7 feet 6 inches. The ceiling height recommendation accommodates a standard 57-inch pool cue.
The standard pool table sizes are 7 feet, 8 feet and 9 feet long, reports ISZY Billiards. In addition, pool cue sizes are 48 inches, 52 inches and 57 inches. While the width and length of a room depends on the size of the pool table, the ceiling height depends on the pool cue length. In order for the pool cue to avoid hitting the ceiling, the ceiling height must accommodate a person using a 57-inch pool cue and performing a 6-inch draw.
