The size of room will dictate to the vast majority of perspective pool table owners as to what will fit. Certainly the floor space is crucial, but also heed to the organization of the room. Having glass windows on the racking side of the pool table is just asking for trouble. Also, having a flat screen tv on the wall next to the pool table may look great (and terrific on game day), until you send a cue ball or stick into it. Graph paper works great, layout the room with the dimensions in our room size chart. The time will be well spent.
