I have an 8' x 3' workbench in the garage that feels plenty of big for anything I did on it that I had to cut down to 6' x 3' yesterday because navigating it with the boat in was very difficult. Pretty sure I won't be going anything under 8' x 3' for the main work area as the 6' x 3' seems tiny now! Maybe I can go smaller if I do two designated work areas. One for jigs and another for plastics.
