Steps to Measure and Select a Window Look
Step 1  Measure the Width and Length of your 
Window Opening to get the Exterior 
Window Opening dimensions (fig.1). 
Remember to include the window frame in 
your measurement.
Step 2  Choose Shutter Style: Louver, Raised 
Panel, Louver-Panel, or Board & Batten.
Step 3  Choose Shutter Type: Standard or Custom. 
Note: Not all shutter styles are available 
Standard and Custom. See Pricing Manual.
Step 4  Determine Shutter Width. 
Note: See charts in Pricing Manual for 
available widths of Standard or Custom 
shutters.
Step 5  Determine Shutter Length.* 
Note: This number should be the same 
number as the window length determined 
in Step 1.
Step 6  Choose a “TOP”: Header, Sunburst Kit, 
Sunburst, Elliptical Sunburst, Quarter Round 
Arch Top or Elliptical Arch Top.
*A note about shutter length. 
Shutters are decorative and do not open and close. 
Because they are decorative, they don't have to match 
the window length exactly. They can be up to an inch 
short or long and will still look fine on a window.
Measuring Windows
Header Options
(Note: Header width is measured 
along the base width of the header 
for windows and doors)
Determine the header width 
(2 options)
Option 1
Use window opening width 
measurement from step 1 on page 1.
Option 2
Use window opening width 
measurement from step 1 on page 
1. Take shutter width from step 
4 and double it. Add these two 
measurements together to get 
header width.
Sunburst Options
Note: Use of half round or elliptical 
sunburst in a look is limited by 
the width of window opening and 
shutter width.
Determine Sunburst Size
Use window opening width 
measurement determined in step 1 
on page 1. 
Note: Sunburst should be the same 
width as the window opening width.
Determine Elliptical Sunburst Size
The elliptical sunburst is available in 
73 ⁄" and 65 ⁄" widths only. To see 
if this look will fit on your window, 
take the window width from step 1 
on page 1 and subtract it from the 
sunburst widths. Take that number 
and divide by two. The final number 
would be your shutter width.
Determine Sunburst Kit Size
The Sunburst Kit is available in size 
ranges. The Header part can be cut to 
fit the desired width. Use the window 
width determined in Step 1 on page 
1. Add the shutter width determined 
in step 4 on page 1 two times. Order 
the Sunburst Kit that fits that size.
