1263 mm and the vertical offset is 81 mm.

All measurements are approximate and may vary from the actual sizes.
BenQ recommends that if you intend to permanently install the projector, you should physically test the
projection size and distance using the actual projector in situ before you permanently install it, so as to make
allowance for this projector's optical characteristics. This will help you determine the exact mounting position
so that it best suits your installation location.
