Short version: How much does/should exterior trim overlap window casing?
Long version: I'm trying to figure out how to position a rectangular window for a spot near the peak of the house. I want to make sure that the exterior trim doesn't collide with the soffits (and leaves an aesthetic spacing). The problem I have is that I don't know how much to plan on the trim overlapping the window.
Hypothetical Numbers: Suppose the window I want to position has a rough-in size of 30" wide by 36" high. The trim I'm using is 5" wide. What will be the final exterior width and height of the trimmed window?
