Question: what is the standard size of a double window?
Answer: Double-hung windows, where both sashes move up and down, are one of the most common window types. These windows start at 24 inches and go up to 28, 32 and 40 inches. Their heights vary from 36 to 72, with heights of 44, 52, 54 and 62. Remember to take 1/2 inch off of each measurement for the correct window size.
