Shutter Width

Measuring Width for Wooden Decorative Shutters and Wooden Functional Shutters
Enter the desired width of your shutters. The way you measure your windows depends on the type of shutter installation - decorative or fully functional.

Decorative Shutter Installation

Decorative installation means the shutters will not open and close, but will be fixed to the wall in the open position. This is a popular installation choice and avoids the added expense of operable shutter hardware.

For decorative installation, it is typically best to find a single width that works for all of your windows. In general it is best to order exterior shutters that are 25% to 33% of the width of your window (including the window frame) for the best look. We have provided the following chart as a general guideline to assist you with choosing the correct shutter width.

Width of your windows Recommended shutter width
30" or smaller 10"
30" to 36" 11" or 12"
36" to 42" 13" or 14"
42" to 48" 15" or 16"
48" to 54" 17" or 18"
54" to 60" 19" or 20"
60" to 66" 21" or 22"
66" to 72" 23" or 24"
72" to 78" 25" or 26"
78" to 84" 27" or 28"
84" or larger 29" or 30"

That said, if you want to make the decorative shutters look like they could open and close, it is also perfectly acceptable. In this case, please follow the measuring instructions for functioning shutters below. Keep in mind that even for a decorative shutter installation, the width of the shutters should never exceed 50% of the window width measurement.

Functional Shutter Installation

To make your shutters actually function, you will need to be more careful when you take your measurements. Take the time to measure accurately as this will ensure your shutters will function the way you expect. Remember - measure twice, and order once!

Measure the width of your shutters as if they were actually closed. This typically means measuring some part of the window trim in addition to the actual window. On brick this usually means measuring the entire opening where the window recesses into the brick, not the actual window. Keep in mind that window widths may vary even on the same window, so it is best to measure at the top, middle, and bottom of the window to get the most accurate measurement. If the measurements are different you must use the SMALLEST of the 3 measurements.

To get the width of shutter required, divide your smallest window width measurement by 2. For example, if the width of your window opening is 35", you should order shutters that are 17½" in width (35 ÷ 2 = 17.5).

For fully functional shutters, measure your windows at the top, middle, and bottom for the most accurate measurement.
