The best way to level a projector is not with a level, as a mm off can produce an inch or more off when projecting.
Realistically, the projector itself has very specific offset for the screen size you have purchased, and you should realistically be able to mount your screen at the proper height, and hit it perfectly if all the measurements are correct. That is, if the projector lens should be 7" above the screen, and on center to the screen, then by measuring everything out, that's what it will be.
But, if you want to hang it properly and check, then you should hang the projector, then project onto a wall. Measure the left side and right side of the projected image. If they are the same size, then the projector is square to the wall left/right. Measure the top and bottom width of the image. If they are the same size, then the projector is square to the wall up/down. Once everything is exactly the same size, you have a projector that is square to the wall and as level as it is going to be.
