1. How to Measure and Determine the Correct Size?

Properly sized Trapezoid Cellular Shades not only provide effective light control but also enhance the overall ambiance and aesthetic of your space. The following instructions will guide you through the measurement process, along with some helpful tips to ensure you determine the correct dimensions before placing your order.

1.1 Helpful Tips Before You Begin Measuring for Trapezoid Windows:
  • For the most accurate measurements, only use a steel tape measure.
  • Be sure not to mix up the measurement results. Always follow the base-height-hypotenuse format and label them accordingly.
  • Measure to the nearest 1/8 inch. Never round up or down to the nearest half or whole inch.
  • If you are measuring for more than one window, measure each one individually – never assume that your windows are the same size, even if they may look alike.
  • Trapezoid Cellular Shades are intended solely for inside mount installation, where the shades are fitted and positioned within the window recess, creating a clean and seamless appearance.
  • Measure the width from left to right at the top, middle, and bottom of the rectangular portion of your window opening.
1.2 What You Will Need

Tools selection:

  • Steel Tape Measure
  • Step Ladder (if necessary)

1.3 How to Measure for Trapezoid Windows
Measure Window Depth
Check Window Depth

Check to see if your trapezoid windows have enough depth for mounting. Trapezoid window coverings typically need a minimum depth of 2 1/4” (5.7 cm) to install brackets and mount the product.

Base Height Hypotenuse
Measure Base, Height, and Hypotenuse
  • Base: Measure the horizontal edge of the window sill from one side to the other within the window opening.
  • Height: Measure the longest vertical edge of the jamb from one side to the other within the window opening.
  • Hypotenuse: Measure the sloped edge of the rake from one side to the other within the window opening.
Important Notes
  • All bottom corners of the window must be 90 degrees.
  • Order your product at the narrowest width and the shortest height. Use the exact measurements, taking no deductions.
  • The factory will apply a small deduction of approximately 3/16 inches (5 mm) during production to ensure a safe and proper installation.

2. Choosing Fabric, Motors & Power Options

To determine which customization options best meet your needs, start by asking yourself the following questions:

2.1 What Level of Light Control Do You Need? What’s Your Interior Design Style?

If you’re looking to gently filter sunlight while maintaining a comfortable level of privacy, light-filtering fabric is a great choice. It allows soft, natural light to enter the room while reducing glare and enhancing privacy. If you prefer a darker environment or need complete privacy—such as in bedrooms or media rooms—blackout fabric effectively blocks incoming light and offers full privacy.

When selecting fabric colors, consider your interior style. Light-colored fabrics complement classic cottage or modern minimalist designs, while darker tones pair beautifully with more traditional or vintage interiors.

2.2 How Do You Want to Control Your Shades? Which Smart Platform Do You Use?
  • Standard Motor:

    • If you prefer everyday control via remote, this motor is the ideal choice. You can freely pair multiple shades with different channels on the remote, while Channel 0 allows you to control all paired shades simultaneously.

  • Smart Motor:

    • We offer a variety of Smart Motors designed to integrate seamlessly with different smart home systems. Choosing the right motor depends on the platform you plan to connect with, and it’s essential to use a compatible hub for successful integration. Visit our “How to Choose Smart Motors” page for an overview of each motor type and their supported platforms.

Motor Type Description
Matter Over Thread Motor Powered by the Matter over Thread protocol, this motor is compatible with any Matter-enabled ecosystem, such as Apple HomeKit, Google Home, Amazon Alexa, or other third-party Matter platforms.
HomeKit Over Thread This motor connects directly to Apple HomeKit, making setup quick and simple.

Compatible devices that can serve as HomeKit hubs include: HomePod mini, HomePod (2nd generation), Apple TV 4K (3rd generation, 128GB), Apple TV 4K (2nd generation).
Zigbee/Alexa Motor This motor runs on the Zigbee protocol and requires a Zigbee hub. It is compatible with Alexa, Google Home, SmartThings, Home Assistant, Hubitat, and Homey.
Z-Wave Motor This motor uses the Z-Wave 800 series chip for stronger connectivity, faster communication, and lower power use. It works with major Z-Wave platforms like SmartThings, Home Assistant, and Hubitat.
2.3 What Power Option Works Best for You?
  • Battery-Powered:

    • Our battery motors are rechargeable via the included Type-C cable. A full charge typically takes 6–7 hours and can last up to six months, depending on usage.

  • Optional Solar Panel:

    • If your window receives ample direct sunlight, especially if it’s hard to reach or lacks an overhang, a solar panel is a convenient add-on. It continuously recharges the battery, reduces the need for manual charging, and minimizes maintenance.

3. What to Know Before Installation?

3.1 Installation Tips

  • Inside Mount Only

    Trapezoid Cellular Shades are designed exclusively for inside mount installation.

  • Mark Bracket Locations Before Drilling

    Before securing the brackets, use a pencil or marker to mark the exact bracket placement on the window frame. This ensures accurate positioning and simplifies the installation process.

  • Installing the Light Blocking Panel

    Each Trapezoid Cellular Shade comes with a compatible Light Blocking Panel. Before installing the panel, attach the mounting brackets to the grooves on the back of the panel. Be sure to insert the clip end of the bracket into the designated slot for a secure fit.

    Note: If your windows are located high up or if installation proves challenging, we partner with Nationwide Blind Installation, Inc. (NBI) to offer professional assistance. You can learn more about these services on our website under the Measuring & Installation Services section. Let our trusted professionals help ensure a smooth, hassle-free installation experience.
