This is a new home and we are deciding on window sizes and heights. We want casements and know they sort of sell larger casement windows than they should (as in, yes we can get large windows but know the hardware will not operate smoothly) because of this we are limiting ourselves to something like 30" wide x 54" tall, 30" wide x 60" tall, or 36" wide x 48" tall. We are afraid anything taller than 4' on the 3' wide casement will be asking for trouble. Overall we are wondering what size to use for the bedrooms, so totally 6 windows.

We are also wondering if it's okay to have the top of the window be higher than the top of a door for example. We prefer to have furniture under the windows for the bedrooms, and if we match the door, that would be 16" from our 8' ceiling, making a 4' window be only 32" from the floor, and a 4' 6" window be 26" from the floor. We think putting the windows below the 8" header would work best interior, but maybe not look as nice outside? Any input from those who have 8' ceilings and used casement windows? It seems double-hung are more popular but that isn't what we are using.
