How many square feet is a 10×12 shed? Of course 120 sq ft should be the obvious answer, but you could be wrong! Depending on which shed plans you use, In some cases, the real inside dimensions of a 10×12 shed can be 107 sq ft or less. That’s because some shed plans (or shed companies, if you buy a shed) use “nominal size” when advertising their building dimensions. Nominal size measurements are taken from roof-edge to roof-edge instead of from the building corners. This means a shed with 5 inches of eave overhangs could be advertised as 10’ wide while only having a real corner-to-corner measurement of 9’2”. Make sure to ask your shed company how their buildings are measured!
The other thing to remember is that outside-to-outside corner measurements are not taking into account the space lost from the thickness of the walls. If your outside corner-to-corner dimensions are a true 10×12, you still need to do a little math to figure out how much inside storage space you have to work with. If your shed is framed with 2x4s, you’ll lose about ¾” from the plywood/siding and another 3½” from the studs. That’s over a 4” difference from outside to inside on each wall, meaning your shed’s interior measurements are about 9’4” x 11’4”. In the end, the actual storage space inside a 10×12 shed with 2×4 walls is often closer to 107 sq ft. This might not matter for your application, but it might matter a great deal. Just be sure to know this before you build or buy.
