How to Measure Windows for Blinds & Shade

Blinds and shades are the top choices for window coverings, particularly in North America and Europe. They are favored for their clean look and excellent light control. The popularity of blackout products is also on the rise worldwide.

That’s why it’s crucial to understand how to measure and size your windows accurately, especially when considering custom blinds and shades. 

By following this simple guide, you can ensure that your window treatments fit perfectly ---- adding an elegant and sophisticated touch to your home.

How to Measure Windows for Blinds or Shades Mounted on the Inside

Step 1: Measure the Width

Start your window measurement on the inside frame in three spots: the top, middle, and bottom. Why three? Well, windows aren’t always perfectly symmetrical. Once you have the measurements, pick the narrowest width of the three. This ensures your blinds will fit snugly and look fantastic.

Step 2: Measure the Height

We take measurements on the left, middle, and right sides of the window. In this case, choose the longest length among the three measurements. Why? Your blinds will cover the entire window, creating a sleek and polished look.

Step 3: Check the Depth

Measure how deep the window is to ensure your blinds have enough space to fit comfortably. This way, they won’t interfere with the window’s functionality.

Additional Tips for Inside Mount:

  • Avoid rounding down when measuring. We will make sure your shades fit PERFECTLY, so provide the exact measurements.
  • Confirm if your window has enough depth for an inside mount. If not, no worries! You can switch to an outside mount or explore other suitable products.
  • Examine the window frame or casing to make sure it’s strong enough to drill into directly.
  • For detailed instructions tailored to a specific product, refer to this measuring finder (choose between the inside or outside mount shades first to get started.)

How to Measure Windows for Blinds or Shades Mounted on the Outside

Step 1: Check the Space

Measure the depth of the window trim or the area above the window. Compare it with the specifications provided for the blinds to ensure you have enough room for an outside mount. This way, you can guarantee a secure and proper installation.

Step 2: Measure the Width

Grab your trusty tape measure and measure the desired width of the blinds at three locations: the top, middle, and bottom. Why three? Well, it’s because windows can have variations. Once you have the measurements, choose the widest one as your width. 

Step 3: Measure the Height

Now, let’s measure the desired height of the blinds at three locations: the left, center, and right. Measure from the top to the bottom. Once again, select the tallest measurement among the three. And don’t forget to report it to the nearest ⅛ of an inch.

Additional Tips for Outside Mount:

  • Allow Extra Space: 

When measuring for outside mount roller shades, make sure to account for the headrail and mounting brackets. To ensure optimal light control and privacy, add enough extra width to completely cover the trim. If there is no trim, add a minimum of two inches on each side for a total of four extra inches.

  • Create the Illusion of a Larger Window: 

Extending the blinds outside the window not only provides space for the mounts but also makes the window appear larger than it actually is, adding a sense of grandeur to your space.

  • Check Mounting Space:

Outside mounts require a flat surface of at least 2 inches above the window or frame to accommodate the mounting brackets. Ensure you have enough space available before proceeding with an outside mount.

  • Consider Projection Brackets: 

If your window has frame molding that might obstruct the blinds, projection brackets can help by extending the blinds further away from the window frame, allowing clearance for the molding.

The use of exterior blinds is growing in both residential and commercial buildings. They help regulate room temperature, reducing reliance on air conditioning or heating systems.

Inside Vs. Outside Mount: Which One Should I Choose?

Before you focus on how to measure windows for blinds or shades, you must decide which type of mounting is right for you. There are different benefits and usages for both.

Inside Mount Your Window Treatments When:

  1. You crave that sleek and minimalist vibe for your space.
  2. Your window trim is absolutely stunning, and you want to flaunt it instead of covering it up.
  3. You want your window treatments to blend seamlessly with the wall; no sticking out allowed!
  4. You have windows with sturdy frames that can handle the mounting hardware like a champ.
  5. You live in a swanky, newer house with perfectly shaped rectangular windows.
  6. Your window sill sticks out, making it tricky to go for an outside mount.

Outside Mount Your Window Treatments When:

  1. You’re on a mission to cover up that unsightly window trim and give your windows a fresh new look.
  2. Your window is rebelliously uneven, defying the perfect rectangular shape required for an inside mount.
  3. You desire maximum light-blocking power when those shades are drawn. Total darkness, here we come!
  4. Your window frame is too fragile or shallow to handle the inside mount.
  5. Privacy is a top priority, and you want to keep prying eyes away when your shades are closed.
  6. You’re all about making your windows look taller, bigger, and more impressive.
  7. When it’s rolled up, you want your window treatment to be as invisible as possible.

How to Measure Windows for Blinds

When measuring for blinds, keep these important points in mind:

  1. Make the mounting decision: Decide if you want the blinds inside or outside the window before measuring. If unsure, measure both ways and then pick your preferred style (refer to the section above for a simple decision.)
  2. Trust the steel tape: Use a steel measuring tape for accurate measurements of your window length and width.
  3. Get precise: Measure to the nearest 1/8-inch, no rounding to a half or whole inch.
  4. Watch for mix-ups: Transposing measurements is a no-no. Stay focused and record the right numbers in the right order.
  5. Width goes first: When noting your measurements, always start with the width and end with the height (W x H).
