New door not square

I am helping install a new 32 in an exterior door. Before I unpacked the door I measured the angles meaning top left to bottom right. The difference between the two measurements is 3/8 on an in. I feel the door is not square, to begin with, and wonder if we should send it back? Any ideas?

If it really is out of square by that much, I would send it back,

Is this a prehung or slab?

Prehung doors are pretty loose, unless there was visable damage it has just shifted out of square during shipping.

A slab door, that would be a manufacturing issue and would be surprised it ever made it out of the plant!

If the slab is square there is no problem. Don't worry about the jamb being out of square. It will be squared to the slab during install.

I find it hard to believe that it could be 3/8" out of square when the slab itself should be perfectly square when you measure the diagonals. (Diagonals, not angles.) I would assume your measurements are wrong, maybe you didn't hook or hold the tape measure the same exact way both times. At any rate, as others have said, when you install it, you square it up. You should have a nice, even 1/8" gap (or so) between the entire perimeter of the door and the jamb. One way to do this is to insert 1/8" shims all around the door perimeter (between door and jamb) and keep the door closed while you plumb, level, shim it and secure it within the rough opening.

Sometimes the jambs on prehung doors are not the same length left and right. Measure the length of the jambs and report back your results.

The door is pre-hung. The jambs are the same. I called HD and they ordered a new one.
