> -Measuring For Shutters
Correct Measuring Is Your Most Important Job
Carefully record your measurements for each window using a good steel tape measure and following the guidelines below.
Measure all widths and heights to the 1/8th of an inch.

Accurate measurements are essential for a proper installation. Shutters are custom made to your specifications and are not returnable due to mistakes in measurements.

Shutters can also be installed on French Doors, Bay and Bow Windows, and on Patio Doors. Click on the link below to measure for doors.

Inside Mount or Outside Mount?
Mounting shutters recessed within the window opening is known as an "Inside Mount". When mounted outside the window opening on the trim (if any) or directly on the wall, this is an "Outside Mount". Usually, if you have enough clearance, inside mounts are preferred. See Clearance Charts to determine the proper mount.


Inside Mount with Z Frame, Trim Frame, or Deluxe Trim Frame (drywall openings),
and L Frames, Mounting Strips, or No Frame (windows with existing trim).

Measuring for Shutters
  • Measure for Clearance See Clearance Charts
  • Measure inside width in 3 places – top, middle, bottom.
  • Measure inside height in 3 places – left, middle, right.
  • Use the smallest actual opening measurements. Factory will take standard deductions for inside mounts to allow for squaring. If making your own allowances, please specify that no deductions should be taken (not recommended).
  • Check for squareness by measuring on diagonal – A & B.
  • Z Frame or Trim Frame units will accommodate most out-of-squareness in drywall openings. If considering Mounting Strips or hinges only, an inside mount is not feasible if diagonal measurements are not within 1/8th inch. Rather, select the L Frame or go to an outside mount.
