I agree that even at 12x12, things'll be "cozy" inside. That's OK. Keep in mind that this will be a general purpose hobby shed, not just a wood working shed. Even 12x8 would be plenty big enough for building 1 meter wingspan bungee launched RC gliders. And for the electronics projects I do, I only need enough workbench space to do some soldering with a 3rd hand (for electric guitar pedals). If I need more room than the shed offers for wood working projects, I'll just roll the table saw down a ramp and do my cutting outside in the sun.

The original design had a height of 35-1/8". Their two-layer top was 1-1/2" thick, so their legs were 33-5/8" long. I want a height of 35", but I'm using a top that's 3" thick. My basement floor is anything but level, so I'm using levelers that are adjustable from 3/4" to 1-1/2". In other words, I want legs that are around 31-3/4" long. (If you're not using levelers, your legs need precise lengths. The levelers give about 3/4" of adjustment, so precision is less necessary.
