The typical 7 foot US pool table is also commonly known as the bar box.

Furthermore, on UK pool tables, the rail edges are not straight before going in to the pockets that has a rattling outward effect when comes in contact with the balls. Last but not the least, the UK pool tables has less diamonds in it. Diamonds are used as a guide for alignments when making difficult shots.
