How to select window size
I'm hoping that someone can help me with selecting the right window size.
We are renovating a kitchen that involves an addition. The design has a window over the sink at 90" wide (finished size). I'm looking at putting in a center picture window with a casement on either side. The RO height is 39 5/8" if that matters.
Is the total RO size an adequate measurement to use to determine a proper fit, and would this take into account the frame around the window? If not, what is the best/safest way to determine the right size?
The windows that I'm considering have separate dimensions for the casements and another for the center picture window. They would be assembled and shipped as one unit.
Any advice is greatly appreciated! Thank you.
