How to Measure for Shutters
Tips Before You Get Started
- Use a steel tape measure for the most accurate measurements
- If you’re considering an Inside Mount, make sure your window has enough depth to accommodate it
- Always measure width (left to right) first and height (top to bottom) second
- Record all measurements to the closest 1/8”, making sure to clearly identify which is your height and which is your width—it is very common to get them mixed up
Determine Inside Mount or Outside Mount
- Inside mount shutters available with Z-Frame or L-Frame options (requires more depth)
- Finished, framed look
- Least energy-efficient mount for shutters
- Outside mount shutters cover beyond your window opening in width and height, L-Frame only
- Mounts on trim or wall surface
- Most energy-efficient mount for shutters
Measuring for Inside Mount
Note: Inside mount shutters will have a small deduction automatically applied by the manufacturer, to ensure proper fit
Width
- Start measurement at 1 ½” deep inside the window opening
- Measure width at the top, center and bottom of your window opening, from edge to edge
- Record the smallest measurement of the three to the closest 1/8”
Height
- Start measurement at 1 ½” deep inside the window opening
- Measure height at the left, center and right, from top edge to bottom edge
- Record the shortest measurement of the three to the closest 1/8”
Measuring for Outside Mount
Note: Outside mount shutters will have no deductions taken at the factory. They will be made according to your exact measurements.
Width
- Measure the area you want to cover (how far you want the shutters to overlap the window opening); we recommend 1 ½” on both sides
- Record your measurement
Height
- Determine where you want the top of your shutter frame to be and mark the spot
- Measure the height from the spot you marked to the top of the window sill. If there is no sill, measure down the window to your desired length
- Record your measurement
