How to Measure

These measuring tips will guarantee your shades are a perfect fit!

Start From Square One Decide Where to Mount the Shade

Before you pick up your measuring tape, decide whether you want to install your shade inside the window frame or on the outside, either on the frame or the wall. An inside mount is usually the best choice since it looks cleaner, but outside mounts are useful if there is not enough depth to mount inside the frame or you wish to block more light...or hide an unpleasant window frame.

See the sections below for full details on each application!

Inside Mount

You're an Insider! This means your shade will be installed on the inside of the window frame, as depicted in the image below.

1

Measure the inside width at 3 locations - the top, middle and bottom. Record the smallest of the 3 measurements. This is your ordering width. Please provide the actual window opening size when you place your order. We will make the necessary deductions.

2

Measure the height at 3 locations - the left side, middle and right side. Record the largest of the 3 measurements. This is your ordering height.

For inside mounts:
Measure the inside of the window frame in 3 places for width and height.

Depth Requirements for Inside Mount

Inside Mounts are the most common application, but they can only be done if you have enough depth from the front of the inside of the window frame to the window itself. There can be no obstructions like crank handles, mullions, and hinges, which can disrupt the operation of the shade.

There are two different types of Inside Mounts: Shallow and Flush.

A shallow mount means that there is enough space to mount the shade inside the frame, but the front portion of the shade will protrude past the window frame because there is not enough depth to mount it fully recessed. If you were to run your hand along the wall or window frame, it would bump into the shade.

A flush mount means that there is enough space to mount the shade all the way inside the frame. The shade is either in line with the frame or even further back, so there is depth from the front of the shade to the front of the frame. If you were to run your hand along the wall or window frame, your hand would not bump into the shade - it would glide over it!

Please refer to the chart below to learn how much depth is required for each lift option and each Inside Mount application:

Minimum Shade Mounting RequirementsStandard & Top Down Bottom Up (with strings)Smoothy Cord Loop, Cordless & Motorized*
Shallow Inside Mount 3/4" 1/2"
Flush Inside Mount 2" 2 1/4"
Shallow Inside Mount with Energy Saving Sidetracks 1 1/2" 1 5/8"
Minimum Flush Inside Mount with Energy Saving Sidetracks 2" 2 1/4"

Measuring for an Inside Mount

  • Use a steel measuring tape
  • Be sure to clearly indicate which measurement is width and which is height. Please mark the width first, then the height.
  • Width - Measure the top, middle, and bottom of the inside of the frame. Write down all three measurements and circle the narrowest width.
  • Height - Measure the left, middle, and right of in inside of the frame from the top of the inside of the frame, all the way down to the sill. Write down each measurement. If you are not getting sidetracks, circle the longest length. If you are getting sidetracks, circle the shortest length.
  • Production takes a slight deduction from the width of the fabric. Please provide the actual window opening size when you place your order. Our Production team will take the proper deduction to ensure the shade doesn't bang against the window frame or other shades.
  • Measure to the nearest eighth inch. If necessary, round down for width, round up for length if you aren't getting sidetracks, but round down if you are getting sidetracks (so the sidetracks aren't made too long!).
  • Always double check your measurements! You know what they say - better safe than sorry!

Outside Mount

You're someone who thinks outside the box, aren't you! This means your shade will be installed on the wall or on the outside of the window frame, like in the image below.

1

Measure the Width (side to side) between the two outermost points of the window frame, or the area which is to be covered. Factory makes no deduction from your shade width dimensions.

2

Measure the height (top to bottom) of the outermost point of the frame to the window sill of the bottom of the frame, or from where ever you want your shade to begin to where you want it to end.

For outside mounts:
Measure the outside of the window frame in 3 places for width and height.

Depth Requirements for Outside Mount

Outside mounts may not be your first choice, but they still do an extraordinary job insulating while providing a nice, finished look. Outside mounts are commonly seen on doors, or if there just isn't enough depth to do an inside mount. They are beneficial if you want to make a window look larger. They also blanket out more light.

So, is there enough room around your window for an outside mount? The chart below describes how much room you need either on the outside of the window frame or on the wall over the window to install an outside mounted shade.

Measuring for an Outside Mount

The key thing here is to measure exactly to where you want the shade and headrail to cover.

  • Use a steel measuring tape
  • Be sure to clearly indicate which measurement is width and which is height. Please mark the width first, then the height.
  • You may want to pencil a mark where you want the headrail to rest at the top of the frame to guide your measurements.
  • Width - Measure the top, middle, and bottom of the outside of the frame. You may want to add a few inches the sides for maximum light coverage. Write down all three measurements and circle the narrowest width.
  • Height - Measure the left, middle, and right of the outside of the frame from the top of the frame, all the way down to the sill. Write down each measurement and circle the longest length. If there is no window sill, measure at least 1 1/2" longer than the bottom of the window.
  • Production does not take deductions from outside mounted shades.
  • Measure to the nearest eighth inch.
  • Always double check your measurements. Production makes every shade exactly to order.
  • Feel free to download our measuring guide. It works like a charm!

Skylight Window Shade (Inside Mount Only)

To ensure a snug fit, make sure that you measure the diagonal measurements of your skylight (top right corner to bottom left corner and top left corner to bottom right corner). If these measurements differ by more than a ¼” you will have to shim your skylight opening to make room for the shade and retainer track.

1

Width: Measure the exact inside measurement of the window at the Top, Middle and Bottom. Write these measurements down, and then circle the narrowest width measurement.

2

Height: Measure the exact inside distance from top of the window to the sill at the Left, Middle and Right. Write down your measurements and then circle the shortest height measurement.

For skylight window shades:
When measuring for a skylight shade, make sure you measure the diagonal measurements (top right corner to bottom left corner and top left corner to bottom right corner). If those measurements differ by more than ¼” you will need to shim your window to accommodate the track system.

Energy Saving Comfortrack SideTrack System

If you are adding Comfortrack Energy Sidetracks to your window shades, always measure the window’s diagonal measurements. This is the top right corner to the bottom left corner and the top left corner to the bottom right corner. Doing this will help you figure out how square your window is.

If your diagonal measurements are within 1/4" of each other, then your window is square enough for sidetracks! If your diagonal measurements are different by more than 1/4", you will need to shim your window to make it square before you can install the tracks.

1

Width: To measure for width, measure the inside measurement from left to right at the top, middle and bottom. Be sure to write all your measurements down, then circle the narrowest measurement.

2

Height: When measuring for height, measure the entire distance from the top of the window at the still to the bottom at the left, middle and right. Write down all of your measurements and then circle the shortest.

Once you have all your measurements written down, check and see that your three widths are within 1/4" of each other. If the widths are too different, you will want to shim any uneven parts to make them closer in measurmenet. Otherwise, there will be gaps between the fabric and the tracks, and no one wants that!

Always double check, and if you’re still unsure, triple check your measurements!
