  • Use a steel measuring tape. Be sure and include the size of your measuring tape in your measurement if used as part of the measuring.
  • Round down to the nearest eighth of an inch.
  • 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.

Before taking any measurements, step back from your window and decide if you want to mount the window treatment inside the window recess, or outside on the wall or molding. We usually recommend an inside mount when possible because it provides a cleaner look. However, an outside mount can make a window appear larger or hide an unattractive window. For an inside mount, the window opening must have enough unobstructed depth to allow mounting. When measuring for an outside mount, be sure to allow for the height of the product's headrail in your measurements.

Some products are available with multiple blinds on one headrail. In order to save money and minimize the risk of shipping damage, consider ordering these as separate blinds/shades and install side by side. On those products that have a valance, be sure to request a common valance and specify the size of valance you want."

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:
For an inside mount: 

Measure the opening width at the top, center and bottom, recording the narrowest width. Always round down to the nearest 1/8", and be sure to use a steel tape measure. See tip below.

Measure the height left, right and center, recording the tallest height.

When you specify inside mount,the factory will make your blind slightly narrower than you specified to allow for operating clearance. They will deduct between 1/16" and 3/8" from the width on each side. The deductions are made so that the blind will not rub or scratch your window frame. So do not take the deduction yourself. Provide the exact window opening width.

For a flush inside mount (the blind completely recessed so that the top of the blind does not project out of the opening) check that you have enough depth.

*When measuring for Skylights - record the narrowest widths and shortest height.



For an outside mount: 

Measure the opening width. If there is room, add at least 3" to each side of the window opening for minimum light gap coverage and maximum privacy.

Measure the opening height. Add a minimum of 2 1/2" in height (3" for 2" horizontal blinds) to allow space for mounting brackets above the opening plus enough overlap for the bottom. If you specify an outside mount, we will not take any size deductions - your blind will be made at the exact size you specify (+/- 1/8"). After determining the measurements that you want the blind to be, hold the tape measure up to your window and visualize what the overall size will look like on that window before proceeding.



Tip: When measuring, don't be surprised if your windows aren't square - many aren't. If they're a little out of square, it probably won't be noticeable. If your window is significantly of square, you might want to consider an Outside Mount to hide the window.
