Checking to make sure your shed floor framing is square.
by: John the shedmaster

Hi Shane, I am sorry to be late in getting to your shed floor question.

The best way to check squareness for your shed floor is to take diagonal measurements of each of the opposing corners. If you checked squareness using for example a framing square in each of the corners, that won't be accurate!

In the picture example, this shed floor is 12' wide by 16' long. Measuring the diagonal of this floor, if it is perfectly square will be 20'. This would be the measurement for each of the diagonals in order to insure that the floor is perfectly square.

If you wanted to find out what your diagonal measurement should be for your floor, you can use a mathematical equation to determine what the length would be for your floor.

That equation is A(squared)+ B(squared) = C (squared). So for the 12'x16' floor I used as an example in the picture, plugging in the numbers, we would get 144 + 256 = C (squared). Or 400 = C (squared). So then taking the square root of 400 would give us our diagonal measurement of 20'.

I hope this helps answer your question. If your floor remains out of square what you can do, if it's not anchored down and the floor sheeting is not on it is take a sledge hammer and beat on the corners slightly from corner to corner until you get equal measurements for each of the diagonals.
