projector screen

[MikeCL]

So I was wondering here.. my projector is being serviced right now so I can't really check with a projected image but I can by measurements. Anyways I was aiming for 109" wide but then I noticed that's the whole face of the wall (7 Ft ceilings) and my speakers would not be in a idea placement. So going down to 90" wide is something like 103" my stand that's going to house the receiver and other equipment is 12 3/8" tall mounting bookshelf speakers I don't think would still have them in the proper position for placement?

maybe I'm really over thinking this? It's confusing since I don't have a picture to go by.. I know the shelf is 12 3/8" tall and the speakers are 14.8" from that point upwards the screen could be a max of 61" tall but with the border and all it might end up looking around 78"
