well I have a gam mil myself but you asked about table size - really honestly it is very rare to have a quilt that you would deed a 4 foot table for I can do a king size on my 12 easily you also have to think about how much space you have you need 13 feet long and about 6 ft wide the more the better but you need 2 feet behind the table to get behind it if you are quilting form the front and you will need good space in the front....
