Imperial pool tables, Hamilton with black wood and felt.

What size is this structure? I want to put a pool table in my garage but doubt there is room.

Clearance depends on the table size and what is around the perimeter of the room.
A 4 1/2 x 9 foot table = 14 1/2 x 19 feet of floor space or more
A 4 x 8 or "bar" table = 14 x 18 feet of floor space
A 3 1/2 x 7 foot table = 13 1/2 x 17 feet of floor space

Ozone Billiards has a similar style pool table http://www.ozonebilliards.com/modern-pool-tables.html
