The minimum area around a table is the playing area plus the length of a cue (58") plus about 6 inches for the backswing, more for comfort. This gives the table:
table playing area room size in meters 8' 44" x 88" 172" x 216" 4.4m x 559m 9' 50" x 100" 178" x 228" 4.5m x 5.8m 12' (snooker) 70" x 140.5" 198" x 268.5" 5.0m x 6.8m
Between two tables you can do with about the length of a cue, the limit is caused not by the cue, but by the player being able to go into his stance between the tables. Deluxe rooms really need more room on all sides to let possible passers-by move without bumping into the players.
