How to Measure for Shades
Your measuring is about to get a whole lot easier at DWCN. Use our handy Measurement Tool to get the right sizing at your fingertips. Or simply follow our easy measuring guide below for a perfect shade fit.
For Inside Mount
Choose an Inside Mount for Your Window Treatments When
- There is enough depth within your window frame to accommodate the mounting hardware.
- You are aiming for a sleek, minimalist aesthetic for your space.
- The window trim is attractive and you wish to showcase it rather than hide it.
- You prefer the window treatment to sit flush with the wall, without protruding into the room.
- Your window frames are sturdy and capable of supporting the necessary hardware.
- The house is relatively new and features standard, uniformly shaped rectangular windows.
- There is an extended window sill that would make an outside mount difficult or impractical.
How to Measure for an Inside Mount
- Measuring the Width
1. Measure the internal width of your window frame in three separate places: at the top, in the middle, and at the bottom sill.
2. Use the smallest of these three measurements as your starting point.
3. From this smallest measurement, subtract 3/8 of an inch. The result is the final width you should order.
Important Note on Light Gaps: An inside mount will typically leave a small gap of about 1/4 inch on each side between the roller shade and the window frame, which can let some light in. If you are concerned about light leakage, an outside mount is recommended. You can add extra width to an outside-mounted shade to ensure complete coverage.
- Measuring the Height (Length)
1. Measure the internal height of your window frame from the top down to the sill. Take this measurement at three points: on the left, in the center, and on the right.
2. Use the longest of these three measurements as the final height you should order.
For Outside Mount
Choose an Outside Mount for Your Window Treatments When
- The window frame is too shallow, irregularly shaped, or otherwise unsuitable for an inside mount.
- You want to conceal unattractive or outdated window trim to refresh the window's appearance.
- You need to maximize light blockage and prevent light leakage around the edges of the shade.
- The window frame is too delicate or weak to support the hardware of an inside mount.
- Complete privacy is your top priority, requiring the shades to fully cover the window and block any view from the outside.
- You want to create the illusion that the windows are taller or wider than they are.
- You want to maximize your view when the shade is open by having it clear the entire window glass when rolled up.
How to Measure for an Outside Mount
- Measuring the Width
Measure the full width of your window frame or trim from the outermost edge to the other. Take this measurement in three locations: the top, middle, and bottom.
Use the widest of these three measurements as your starting point.
For optimal privacy and light control, add 1 to 3 inches to this widest measurement. The final number will be your order width.

- Measuring the Height (Length)
Determine the desired mounting position for the top of the shade. We highly recommend mounting the headrail 4 to 6 inches above the top of the window frame. This allows the shade to clear the glass when fully rolled up, maximizing your view.
Measure from your chosen mounting point down to the desired bottom edge of the shade (this is typically just below the window sill). This measurement is your order height.
*Note on Mounting: To ensure the rolled-up shade does not obstruct the window, always mount the headrail at least 4 inches above the window frame. This provides the necessary space for the headrail and the rolled-up fabric.
