How to Measure for your Shutters
You can gather your measurements from inside your house by opening the window. It will help to record your findings as you measure, or even draw a simple diagram of your window with the measurements labeled. Measure the height and width of your window opening where the shutters would rest in a closed position. Since windows aren’t always perfectly square, taking two measurements – one on each side of the window height, and the top and bottom widths – is important.
Arch Top Window
Gather the windows rectangular measurements as mentioned above – leaving the arch section out of the measurement at first. Then measure the height from the bottom of the window to the highest point of the arch top (usually up the very center of the window). This will be your largest measurement.
