Measuring Basics

    • Use a tape measure in good working condition, with no damage to the "hook".
    • Measurements should be made for each individual window. Do not assume similar-looking windows are the exact same size.
    • Measurements are normally stated in "Width" and then "Height".
    • Measurements should be made to the nearest 1/16".
    • The Screen Rough Opening (SRO) refers to the exposed edge of the window frame that will support the screen.
