I'm looking to install a pool table but I'm not sure if it is possible in the space I have.
The area is 8.5' by 17'.
Would this be enough room to play any sized table without play being hindered?
A standard pool table is 5 feet by 10 feet, leaving 1.5 feet at each side of it, if installed in your room.
The average person would struggle to walk around your table, let alone play on it.
There are smaller sizes of table, but given the standard cue of 4 to 5 feet and the need for at least half that distance in making a stroke from the cushion, you would barely get 1 foot of playing surface across. Suffice it to say, you do not have enough space for playing pool.
TL;DR: Your room is too small to allow you to easily play pool.
The minimum for the short side of the room is around 13".
The basic rule is that you need 4.5" all around the table to allow a player to "enter" the cue.
