Shed dimensions

So my HOA says I can add a Shed to my property.

The major restriction is 100 sqft
So the question for the day is...

10x10
9x11
8x12.5

I feel like 10x10 would be the best shape for a shop with blast cabinet, storage, press, drill press, maybe a small part paint booth, grinder.

I can see in my head that rectangular might make better use of the space inside by providing a longer wall .

What say you?

4'x25' divide it so clean stuff is in one section & grinding/blasting & such is in the other... Make it 9-10 tall & set it up so the upper area is storage....
