Inside Mount vs. Outside Mount: Which is the Right Choice for You?

Before measuring your windows for blinds or shades, it's important to first determine the right mounting option for your space. Both inside and outside mounts offer unique advantages and are suited to different needs, so choosing the appropriate style will ensure the best fit and functionality.

When to Opt for an Inside Mount for Your Window Treatments:

Adequate window depth to accommodate an inside mount.

Ideal for achieving a clean, minimalist look in your space.

When the window trim is an attractive feature you want to showcase rather than cover.

Preferred for window treatments that integrate seamlessly with the wall without protruding.

Suitable when the window frames are sturdy enough to support the mounting hardware.

Best suited for newer homes with well-structured, rectangular windows.

An inside mount is ideal if the window sill extends outward, making an outside mount more challenging.

When to Choose an Outside Mount for Your Window Treatments:

The window lacks sufficient depth and has an irregular shape, making it unsuitable for an inside mount.

The goal is to conceal unattractive window trim and refresh the overall appearance of the window.

An outside mount is preferred when maximum light-blocking capability is required.

The window frame is too fragile or shallow to support an inside mount securely.

Privacy is a top priority, and the shades must effectively block the external view when closed.

An outside mount can help create the illusion of taller, larger windows.

The window treatment should be as discreet as possible when rolled up.

Measure the Window for Inside Mount

① Measure the Depth

Measure the depth at the top of the inside window casing to ensure there is sufficient space for a secure inside mount. This measurement is also crucial for determining whether a flush mount—where the window treatment fits entirely within the frame without protruding—is feasible. The required minimum depth varies by shade type, so please refer to the depth requirements listed below for each style, which are essential for achieving a proper inside mount.

② Measure the Width

For shades: Given potential variations in window shapes, it's advisable to take measurements at three points: the top, middle, and bottom. Round each measurement down to the nearest 1/8 inch for accuracy.

③ Measure the Length

When determining the length, measure the window in three locations: along the left, center, and right sides. Round each measurement up to the nearest 1/8 inch, and use the largest measurement as your ordering length.

Note on Deduction

To ensure the shade fits correctly, take the smallest of these measurements and account for any required deductions to obtain the final width measurement.

For Roman Shades and Bamboo Shades, headrail width = ordered width (after deduction 3/8 inch from window frame)
For Roller Shades and Zebra Shades, headrail width = ordered width (after deduction 3/8 inch from window frame)
For Cellular Shades and Venetian Shades, headrail width = ordered width (after deduction 1/4 inch from window frame)

Measure the Window for Outside Mount

① Check the Space

Measure the space above the window to ensure it’s sufficient for secure installation of the brackets and headrail.

② Measure the Width

Measure the width of the window from outer edge to edge. If possible, add 2-4 inches (1-2 inches per side) to minimize light seepage. This adjusted measurement will be your ordering width, representing the total width of the shade.

③ Measure the Length

Measure the height of the window from outer edge to edge. If possible, mount the shade 10-12 inches above the frame to allow for its stack height when rolled up and to maximize window exposure.

Allow Extra Space: When measuring for outside mount shades, account for the headrail and mounting brackets. To achieve optimal light control and privacy, add sufficient width to fully cover the window trim. If there’s no trim, add at least 2 inches on each side, totaling 4 extra inches.

Enhance Visual Appeal: Extending shades beyond the window frame not only accommodates the mounts but also creates the illusion of a larger window, adding an elegant and expansive feel to your space.

Ensure Adequate Mounting Surface: Outside mounts require a flat surface at least 2 inches above the window or frame to securely hold the brackets. Verify that you have enough space before starting the installation.

Use Projection Brackets if Needed: For windows with protruding frame molding, projection brackets can extend the shades outward, ensuring they clear the molding and operate smoothly.
