Inches.
The united-inches (UI) measurement of a window, or a window opening, is simply the sum of the greatest width and greatest height of the rectangle.

Windows companies each have their own charts from which they can look up materials quantities and costs and your estimated price for a window of a particular UI measure. Your windows provider will want to do their own final measures, to protect you and them from error, and so they can take into consideration any unique factors.
