Size does matter…. ;-) Bigger the table, lower I would make it. I made the 7' one much lower, figured I would be working on bigger airplanes on it. One of the other ones, I put higher because I knew I would never sit at that bench and wanted the storage underneath for my radial arm saw and other tools I rarely use. My shop is almost done, once it was functional, kind of gave up on some of the final touches.
