The other part of the guess work is that the quilting will take up part of the backing, and THAT depends on how close the quilting is or what the quilting pattern is, and can even seem random. You might add borders that can be sacrificed or left on as the quilting demands. Like others have said, talk to the LA'ern about what you want.
