How do you determine if a wall is plumb?
To check for accurate plumb vials, rest your level against a wall and note the location of the bubble between the lines. Then rotate the level 180 degrees, edge to edge, keeping the same end facing up. The bubble should be in the same spot. If not, your plumb vial is off.How much is a brick wall out of plumb?

Foundations walls should be level within 1/4 inch in 10 feet, while the entire foundation should be level within 1/2 inch. The Handbook states that there is no single accepted tolerance for rough framing, although a tolerance of 1/4 inch in 10 feet is frequently used and is acceptable.
Whats the difference between plumb and level?A vertical framing piece, such as a post or stud, is “plumb” when it’s perfectly straight, and when a horizontal member has no tilt, it is “level.” The tools that carpenters and homeowners use to determine plumb and level all rely in some way on gravity.

Under 1/8″ is typical (even on much larger buildings), but it’s just a shed, so @batsplatsterson has an answer I’d agree with. If using sheet goods (plywood, OSB) for roof and floor you’ll have some extra waste to trim due to the out-of-square condition. Effect on the walls should be minimal.
