Vertical Blind Measuring - Outside Mount
  • Use a steel measuring tape and measure down to the nearest 1/8".
  • On your notes, clearly indicate which measurement is the width and which is the height. It is very common to transpose measurements. Always indicate the WIDTH measurement first, then the HEIGHT last. (W x H)
  • Remember one very important thing when measuring for an inside mount - Take the ACTUAL WINDOW OPENING SIZE to give to us, our factory will take all the proper allowances for it to fit into that opening.

Be Confident: Inside or Outside Mount-Which To Choose?
  • Decide which you want BEFORE you take any measurements.
  • We usually recommend an inside mount because it provides a cleaner look.
  • However, an outside mount can make a window look larger or hide an unattractive window.
  • If you want an inside mount, make sure the window opening has enough unobstructed depth to allow for mounting.
  • If you want an outside mount, be sure to allow for the height of the product's headrail in your measurement.

Always remember: we will custom make your blinds to the sizes you write on the order. If these sizes are incorrect it is impossible to change the blind, so take your time and double check your measurements.

Specific Measuring Instructions Below:

 Measuring for OUTSIDE MOUNT: 

Measure the opening width. If there is room, add at least 4" on each side of the window opening to ensure minimum light gap. Measure the opening height. Add a minimum of 2 1/2" in height to allow for mounting brackets above the opening and add your desired overlap for the bottom. If your window treatment will hang down to the floor, please allow at least 1/2" clearance on the bottom for proper operation. If you specify an outside mount, we will not take any size deductions - your blind will be made at the exact size you specify.
