How to Measure

Our step-by-step instructions make it easy to take accurate measurements and get the right fit.

How to Measure


 
 
 
Measure For Inside Mounting
Measure For Inside Mounting

Mounting Shutters Inside a Window Opening (With or Without Molding)

  1. 1. Measure the inside of the window opening, not the glass.
  2. 2. Measure window width in 3 places. Record the narrowest measurement and round down to the nearest 1⁄8 in.
  3. 3. Measure window height in 3 places. Record the shortest measurement and round down to the nearest 1⁄8 in.
  4. 4. Do not make any deductions, allowances or additions.
  5. 5. Check for squareness by measuring on diagonals
 

Note: If diagonals are not the same, (less than 1⁄2 in. difference) and the window does not have a molding, a trim frame, décor trim frame, or bullnose frame are suggested to allow for easier installation. If diagonal measurement differs by more than 1⁄2 in., choose outside mount.

 

Measure For Outside Mounting

Mounting Shutters Outside a Window Opening (Window Without Molding - (For Casing Frame and L Frames Only)

  1. 1. Measure the inside of the window opening, not the glass
  2. 2. Measure the window width in 3 places. Record the widest measurement. Round up to the nearest 1⁄8 in.
  3. 3. Measure the window height in 3 places. Record the longest measurement. Round up to the nearest 1⁄8 in.
  4. 4. It is necessary to have 1 5⁄8 in. additional space on all sides of the opening to mount frames.
 

Note: We will add necessary adjustments to your window measurements so that shutter will mount directly around window. If you desire your shutter to be a specific width or height, order as exact outside mount finished size.

 
 
Measure For Outside Mounting

Mounting Shutters Outside a Window Opening (On Existing Molding - For Casing Frame and L Frames Only)

  1. 1. Measure the width to the outer edges of the molding in three places (your molding is part of the measurement). Record the widest measurement rounding up to the nearest 1⁄8 in.
  2. 2. Measure the height to the outer edges of the molding in 3 places (your molding is part of the measurement). If you have a sill, measure from the top of the sill to the top of the molding. Record the longest measurement rounding up to the nearest 1⁄8 in.
  3. 3. Do not take any deductions, allowances or additions.
 

Special "MUST" Requirements:

  • Molding must be at least 1 1⁄4 in. wide, and have at least 3⁄4 in. flat surface. The minimum width of trim required for Casing Frame is 2 5⁄8”, L-Frame is 1 3⁄8”.
  • If your molding does not meet the above specifications, you must hang your shutters onto the wall, beyond and around the molding.

 
 
 

Measuring for Depth Clearance

Depth clearance is the minimum window depth required for shutters to operate without interfering with window parts.

Measure from the front of any obstruction to the front edge of the window frame to determine depth.

 
Minimum Depth Clearance by Frame (inches)
Inside Mount (IM) - with frame or panel with front of window
Frame Type 2 1⁄2 in. Louver Tilt Bar, Gear
Closure System or Motorization
3 1⁄2 in. Louver Tilt Bar, Gear
Closure System or Motorization
4 1⁄2 in. Louver Tilt Bar, Gear
Closure System or Motorization
Mounting Strip 2 1/8" 2 3/8" 2 7/8"
L Frame 2 1/8" 2 3/8" 3"
Z Frame 1 1/4" 1 5/8" 2 1/8"
Bullnose Frame 1 3/8" 1 5/8" 2 1/8"
Trim Frame 1 1/8" 1 1/2" 2"
Décor Trim Frame 1 1/8" 1 1/2" 2"
Outside Mount (OM)
L Frame 0" 1/2" 7/8"
Casing Frame 0" 0" 5/8"

NOTE: If your window does not meet minimum depth for outside mount, then frame extensions are available. Each frame extension will increase clearance by 1⁄2 in. The Gear system has the same depth clearance as the Tilt Bar application.

 

Locating Divider Rails

Divider rails separate the top louvers from the bottom louvers. This allows the bottom half of shutters to be fully closed for privacy, while allowing the upper half to be open.

A divider rail is required for any shutter panel over 66-inches in height. Two divider rails are required for shutters over 90-inches in height. There is no extra charge for divider rails.

You can request the approximate height of the divider rail placement at time of order.

Simply provide the measurements from the bottom of shutter to the center of the divider rail location.

Note: If there are two divider rails along with motorized tilt, the mid-section of louvers will operate simultaneously with either the top section of louvers or the bottom section of louvers. Preferred configuration must be selected at time of order.

Note: The divider rail location may vary up or down by 1 1⁄2 in. from the height requested.

 

Achieving Panel Consistency

All shutters must be ordered the same height to achieve a uniform appearance and equal number of louvers. If the height measurements differ, apply one of the options below:

  • For inside mount mounting strip or L frame you may reduce taller shutters up to 1⁄8 in maximum.
  • For inside mount with Z frame, Bullnose, Trim frame or Décor Trim Frame you may reduce taller shutters up to 1⁄2 inches maximum.
  • For height adjustments of more than 1⁄2 inches, we recommend an outside mount.

Note: Panel consistency is easier to attain with framed shutters, Height adjustments to achieve consistency are not recommended for mounting strip applications.

 

French Door with Cutout

Outside mount - 4-sided frame on top or around the molding

Measure Width

  • 4-sided L frame is used for French Door application.
  • Depth clearance and obstructions can prevent louvers from operating properly. In order to overcome these obstacles, we will add the necessary number of L frame extensions.
  • Up to (3) 1⁄2 in. extensions can be added to the L Frame.

Measure Outside Width (A)

  • If mounting on top of molding, then measure outside edge of molding to outside edge of molding in three places (top, middle, and bottom). Molding should be a minimum of 1 3⁄8 in. so that it is wider than the shutter frame. Record the largest measurements to 1⁄8 in. — not for use on a curved profile molding.
  • If mounting around the molding, then measure the outside width of the molding. Round to the nearest 1⁄8 in.

Measure Outside Height (B)

  • If mounting on top of molding, then measure outside of molding to outside of molding in three places (top, middle, and bottom). Molding should be a minimum of 1 3⁄8 in. so that it is wider than the shutter frame. Record the largest measurements to 1⁄8 in.
  • If mounting around the molding, then measure the outside width of the molding. Round to the nearest 1⁄8 in.

Measure Depth of Molding

  • Measure the depth or projection of the molding that protrudes from the door, and note on the order form.

Cutout Height (C or D)

  • Measure from the bottom of the molding to the middle of the desired cutout location.
  • The cutout can be centered on the door handle ("C") or centered between the door handle and the deadbolt ("D").
  • An optional divider rail may be ordered. The divider rail will be positioned on center of the cutout
Measure For Outside Mounting
 

Note: Shutter height may be ordered longer than molding to molding measurements. This allows the shutter to be moved up or down in order to center the cutout as needed.

  • 4-sided L frame only.
  • Cutout size is always 15 inches.
  • Minimum cutout height location is measured from bottom of shutter frame.
Panel Configurations

By-Pass

  • Inside mount must have a minimum jamb depth of 2 in.
  • Outside mount standard by-pass will project 6 5⁄8 in. from the wall.

Shutter louvers cannot open when panels are stacked in front of one another.

Panel Configurations

Mounting inside a window opening

  • Measure inside the window opening in 3 places for A & B. Record the smallest measurement and round down to the nearest 1⁄8 in.
  • Do not make any deductions, allowances, or additions.
  • Check for squareness by measuring diagonals.

Squareness Check

  • Measure diagonals — If not the same then inside mount is not recommended.

Mounting outside a window opening

  • Measure outside the window opening in 3 places for A & B and record the largest measurement.
  • You will need 2 1⁄4 in. above the window and on each side to mount the frame.
  • To cover an area larger than the window opening simply provide the desired finished width (up to 180 in.) and height (up to 120 in.).

Only if divider rail is being used

  • The measurement recorded is determined from the bottom of the floor or sill to the middle of where the divider rail is to be located.
  • One divider rail is required for panels over 66 in. with a maximum 50 in. between the middle of the divider rail and either top or bottom rail.
  • Two divider rails are required for panels over 90-inches in height with a maximum 50 in. between any two rails.
