I had also planned on a module table, using 30" squares. Three squares wide, and six squares long. But, with the on-set of arthritis, I had to reduce the demensions, to insure I could reach over every inch of the table to game. The squares became 29"x29". My table is made-up of 18 squares measuring total 14'6" x 7' 3". It makes a good size area for movement for my 25mm figures. Also, I can use just half the table, or even just 6 squares for smaller games. Works out very well....Not to mention, I sometimes have two different games going, one at each end.
