What’s the Difference Between Outside Mount and Inside Mount Shades/Blinds?

When choosing custom shades or blinds, you need to decide between inside mount and outside mount installations. Understanding these two options will help you determine the best fit for your window and your desired look.

Inside Mount (Recessed Installation)

What It Is:
Inside mount shades or blinds are installed inside the window frame, sitting flush within the recessed area. This creates a clean, built-in look that blends seamlessly with your window.

Key Features:
✔️ Sleek and minimalistic appearance
✔️ Takes up less space, keeping your window trim visible
✔️ Works well when your window frame is deep enough to accommodate the shade or blind

When to Choose Inside Mount:

  • You prefer a clean, fitted look that integrates with your window
  • Your window has enough depth (typically at least 2.5 to 4 inches) for proper installation
  • You want to layer curtains over your blinds or shades for added style

Important Note:
Since inside mount shades must fit within the window frame, precise measurements are crucial. You'll need to measure the exact inside width and height of your window opening and possibly subtract a small fraction (e.g., ⅜ inch) to ensure a smooth fit.

 

Minimum Depth Requirements for Inside Mount of Different Shade/Blinds Types

Shade Type Depth Requirement

Roman Shades 2 1/2

Bamboo Shades 2 3/4

Roller Shades 4

Zebra Shades 3

Cellular Shades 2 1/2

Venetian Blinds 3

Outside Mount (Frame or Wall Installation)

What It Is:
Outside mount shades or blinds are installed outside the window frame, either on the wall or on the trim surrounding the window. This option allows the covering to extend beyond the window edges, providing extra light control and coverage.

Key Features:
✔️ Makes windows appear larger and creates a dramatic effect
✔️ Offers better light blockage by covering the entire window and reducing gaps
✔️ Ideal for windows with shallow frames or obstructions inside the recess

When to Choose Outside Mount:

  • Your window frame is too shallow for an inside mount
  • You want to maximize light blockage and privacy
  • You prefer a bold, statement-making window treatment

Important Note:
For an outside mount, you'll need to measure beyond the window opening—typically adding 2-6 inches on each side to ensure full coverage.

Which One Should You Choose?

🔹 Go with inside mount if you love a clean, built-in look and have enough window depth.
🔹 Choose outside mount if you want maximum light control, a bold appearance, or have a shallow window frame.

Before You Begin

  • Tools You’ll Need:
    • A sturdy steel tape measure (avoid fabric tapes for more accurate results)
    • A pen and paper (or digital note-taking app) to record measurements
    • A step ladder (if needed, for higher windows)
    • A helper (optional, but useful for ensuring accuracy)
  • Preparation:
    • Ensure the window and surrounding area are clean and free of obstructions.
    • Take your measurements during daylight hours for better visibility.

Step 1: Measuring the Width

For an Exterior Mount (Outside Mount)

  • Measure Across the Entire Window:
    • Include any window mouldings or trim in your measurement.
    • Measure from the left outer edge to the right outer edge of the window.
  • Add Extra for Overlap:
    • To ensure complete coverage and proper operation, add an extra ½ inch to your measurement.
    • Example: If your window’s total width is 50 inches (including mouldings), record 50 inches + ½ inch = 50.5 inches.

Important Tips:

  • Always measure at the top, middle, and bottom of the window. Use the narrowest measurement to ensure a proper fit.
  • Write down your final width measurement clearly.

 

 

Step 2: Measuring the Height

For an Exterior Mount (Outside Mount)

  • Measure the Full Height:
    • Begin at the top of the window frame or moulding.
    • Extend the measurement down to the desired end point (this might be the window sill, just above the floor, or a custom endpoint depending on your preference).
  • Include Additional Length:
    • If you desire a longer shade that pools slightly on the floor or overhangs, add an extra 3 inches.
    • Example: If your window height (from top moulding to the desired bottom edge) is 40 inches, record 40 inches + 3 inches = 43 inches.

Important Tips:

  • Check your measurement at different spots if the window is uneven.
  • Use the longest measurement if you plan for the shade to extend fully for maximum light blockage.

Step 3: Additional Considerations

Depth of Window Frame:

  • For window frame depths less than 2 inches:
    • Measure the width including mouldings and add an extra ½ inch.
    • Measure the height including mouldings and add an extra 3 inches.

General Advice:

  • Double-check your measurements. Accuracy is crucial for a perfect fit.
  • If you’re unsure about any step, consider seeking assistance from our customer service team.

Example Scenario

Let’s say you have a window with the following details:

  • Width: The total width (including mouldings) is 50 inches.
    • Add an extra ½ inch → 50.5 inches.
  • Height: The total height (from top moulding to the desired endpoint) is 40 inches.
    • Add an extra 3 inches → 43 inches.

Your final measurements for your custom exterior shade/blinds would be:

  • Width: 50.5 inches
  • Height: 43 inches

By following these steps, you’ll be able to provide accurate measurements for your custom shades and blinds, ensuring a perfect fit for your exterior window. If you have any questions or need further assistance, please feel free to contact our customer service team.
