Measuring for AESTHETIC MOUNTED Shutters

To determine shutter width, measure the closed shutter pocket width and divide by two. This number will determine the width of each shutter for that window. For Bahama styles, shutter width is equal the actual shutter pocket width less 1⁄2".

The shutter height is equal to the closed shutter pocket height.

Shutter Width (Round to nearest 1⁄8" ) = Closed Shutter Pocket Width ÷ 2

Shutter Height (Round down to nearest 1⁄8") = Closed Shutter Pocket Height

Arched Windows (High and low height measurements required.)

Measuring for FUNCTIONAL Shutters

• Shutters closing INSIDE a brick or trim pocket

The following are suggested formulas based on the proper use of exterior shutter hardware and standard installation methods.

Identify the closed shutter pocket. Measure across the closed shutter pocket at the top and bottom of the opting and use the smallest measurement. For Bahama style shutters, see instructions below.

TRADITIONAL SHUTTER MOUNT

Shutter Width (Round down to nearest 1⁄8".) = Closed Shutter Pocket measurement less 1⁄2" clearance ÷ 2

Shutter Height (Round down to nearest 1⁄8") = Closed Shutter Pocket Height less 1⁄2" clearance

Arched Windows (High and low height measurements required.)

BAHAMA SHUTTER MOUNT

Shutter Width (Round down to nearest 1⁄8") = Closed shutter Pocket measurement less 1⁄2"

Shutter Height (Round to nearest 1⁄8") = Closed Shutter Pocket Height less 1⁄2"

• Shutters closing OUTSIDE a brick or trim pocket.

To determine shutter width, measure the window opting pocket width and divide by two. This number will determine the width of each shutter for that window. (For Bahama styles, shutter width is equal to the actual window opening pocket width plus 3"; shutter height is equal to opening pocket height less 1⁄2")

Shutter Width (Round to nearest 1⁄8" inch.) = Window Opening Pocket Measurement ÷ 2

Shutter Height (Round to nearest 1⁄8" inch.) = Window Opening Pocket Height less 1⁄2" for clearance

Arched Windows (High and low height measurements required.)
