corners are 5 1/8th and sides are 5 3/4
To get the table to 4.5" pockets means you are going to have to account for a 5/8" gap (5/16" on each side of the pocket). I don't care if you stack facings or use a one piece 5/16" facing, the table is going to play like crap around the pockets. Neoprene is a different material than the cushion so regardless of what duro facing is used to close the gap, it will not play good at all. Rather than waste the time and money on a snake oil fix, it is recommended to do it right or live with the buckets.
