How To Measure 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

Note: Inside mount shutters will have a small deduction automatically applied by the manufacturer, to ensure proper fit.

Width

• Measure at the depth within the frame where you’ll install your brackets
• 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

• Measure height at the left, center and right, from top edge to bottom edge
• Record the largest measurement of the three to the closest 1/8”

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 shutter 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 below the window opening to your desired length
• Record your measurement
