Measure Windows for Exterior Vinyl Shutters

  1. Width:

    Vinyl shutter width depends on the space available around a window, as well as desired appearance. For an appearance of functioning shutters, panel width should be about half the width of the window, although not required for non-functional decorative exterior vinyl shutters.

  2. Height: 

    Measure the height of each window or door (sash) and order the vinyl shutters the same heights. Shutter height is the distance from the lowest to the highest part of the panel.Measure for louvered vinyl window shutters.

Arched Top: Use the same instruction to measure outdoor vinyl arch top shutter width as for rectangular panels. The shutter height ordered is the full height of the exterior shutter including the arch.

A springline dimension is required to order arch top shutters. Ascertain the springline by measuring from the top of the window down to the start of the arch. Many arch tops have a 1-to-1 (1:1 drop) where the springline equals the shutter width.

Guidelines: To achieve the appearance of functioning shutters, panel widths should be about half the width of the window. However, non-functional vinyl exterior shutters will never be closed over windows and are installed only as decorative accents to improve the appearance of the home or building.

It is acceptable to install stationary shutters the full height of the window trim, which in some cases appears more symmetrical.

Large or bay windows are often too wide to use panels that appear to be functional, so often a smaller panel is appropriate.
