In choosing the width of your exterior shutters, you should take into consideration the width of the window
and the distance the windows are spaced apart. It is generally best to find a single width that works for all of
your windows. The width that usually works best is between 25% and 33% of the total width of your window
including the window trim. Refer to the chart at the right.
When using vinyl shutters on windows that are wider than 50 inches, we recommend using double wide vinyl
shutters. However, if you prefer not to use the bi-fold shutter style, you can use 18" wide shutters and it will
still look reasonably well.
If you prefer to make your outside shutters look like they will close over the windows, find a width that is
close to 50% of the size of the glass and window frame only, excluding the window trim. Since vinyl shutters
don't have that much flexibility in terms of shutter width, it is best to err on the side of the exterior shutters
being narrower than 50% of the window width.
