What is the difference between a recess and exact fitting?

A blind that is fitted within the window recess will be about the same size as the window, and it will fill the window area. A blind that is fitted outside of the recess is normally referred to as an exact fitting, and is attached to the wall above the window, covering both the window and part of the wall on either side of the recess. Choosing which fitting to go with can depend on a number of factors but usually comes down to aesthetics; which look do you prefer?
