Bay windows are an architectural gem that adds a sense of space, elegance, and charm to any room. These unique windows not only offer panoramic views but also allow an abundance of natural light to flood in. However, their multi-angled design makes finding the right blinds and shades more challenging compared to standard windows. Accurate measurements are crucial to ensure a perfect fit for blinds and shades, allowing you to enjoy privacy, light control, and an aesthetically pleasing design.
In this comprehensive guide, we will cover the following:

1. Understanding Bay Windows and Their Challenges
Before we dive into the measuring process, it’s essential to understand why bay windows are unique. A bay window consists of three or more windows that angle out beyond the exterior wall of the home. These windows are typically set at 30°, 45°, or 90° angles, forming a bay or alcove. The central window is often the largest, flanked by two or more smaller windows. This design makes the room feel more expansive, inviting more light into the space.
Challenges When Measuring Bay Windows:
- Irregular Angles: Bay windows have angles that differ from traditional flat windows, which adds complexity to measuring accurately.
- Multiple Surfaces: You’re working with three or more panes of glass, each needing its own treatment and careful attention.
- Precise Fitting: Getting the blinds or shades to fit neatly into each section without gaps or overlapping can be tricky.
- Aesthetic Harmony: Ensuring the treatments for each section of the bay window align harmoniously for a clean, cohesive look.
To address these challenges, taking precise measurements is critical. Let’s look at the tools you need to get started.
2. Tools You Will Need
Accurate measuring is the foundation of any successful window treatment installation. Gather the following tools:
- Steel Measuring Tape: A reliable steel tape measure (preferably in inches and centimeters) is essential for precise measurements.
- Step Ladder: For easy access to higher sections of the window.
- Pencil and Paper: To write down each measurement carefully. Consider using a measuring sheet to keep the measurements organized.
- Level: A spirit level can help ensure your measurements are accurate, especially for larger windows.
- Angle Finder: Optional, but useful for measuring the angles of your bay windows to ensure accurate blinds and shades placement.
Once you have your tools, decide whether you want an inside mount or an outside mount for your blinds or shades.
3. Steps for Measuring Inside-Mounted Blinds
An inside mount is when the blinds or shades are installed within the window frame, creating a clean, streamlined look. This option is ideal for bay windows if you want to highlight the window’s architectural details. Follow these steps to measure for inside-mounted blinds:
Step 1: Measure the Width of Each Window Pane
- Start with the left windowpane. Measure the inside width at three points: the top, middle, and bottom of the window frame.
- Write down the smallest measurement. This ensures the blind fits inside the narrowest part of the window.
- Repeat this for the center and right windowpanes.
Step 2: Measure the Height of Each Window Pane
- For each windowpane (left, center, and right), measure the height from the top inside edge to the bottom inside edge.
- Measure in three places: the left side, center, and right side of each windowpane.
- Record the longest measurement for each pane to ensure full coverage.
Step 3: Measure the Depth
- Measure the inside depth of the window frame. This is especially important for inside mounts, as blinds and shades require a certain amount of space to operate correctly.
- Most blinds require at least 1 to 2 inches of depth for an inside mount.
Step 4: Account for the Window Angles
- Using your angle finder (or even a protractor), measure the angle between the panes. This will help ensure that the blinds don’t overlap awkwardly or leave gaps.
4. Steps for Measuring Outside-Mounted Blinds
An outside mount is when the blinds or shades are mounted on the wall or molding outside the window frame. This option is better for those who want to create the illusion of larger windows or need full coverage for better light control.
Step 1: Measure the Width of Each Window Section
- Measure the width from one edge of the trim to the opposite edge (or wall, if there’s no trim). Measure the left window, center window, and right window separately.
- Add at least 2-3 inches to your measurement on each side for overlap. This ensures complete coverage and better light control.
Step 2: Measure the Height
- Measure from the top of the window frame (or desired starting point on the wall) down to where you want the blinds or shades to end. This is typically just below the window sill or down to the floor for longer shades.
- Add 3-5 inches to this measurement for optimal light blocking and privacy.
Step 3: Consider the Projection
- For an outside mount, you’ll need to account for the projection, especially if your window treatments will cover trim or molding. Add the depth of the window frame plus an additional inch or two for clearance.
5. Common Mistakes to Avoid
Here are some common pitfalls when measuring bay windows for blinds and shades:
- Not Measuring at Multiple Points: Bay windows, especially older ones, can be irregular in shape. Always measure the width and height at multiple points and use the smallest (for width) or largest (for height) measurement.
- Forgetting About Obstacles: Look out for window cranks, handles, or other obstacles that could interfere with the operation of the blinds.
- Not Factoring in Depth: If you choose an inside mount, the depth of your window frame is crucial. Blinds need a specific amount of depth to operate smoothly.
- Incorrect Overlap for Outside Mounts: Ensure there’s enough overlap on both sides of the window for outside mounts to prevent light from leaking through the sides.
6. Final Tips for Accurate Measuring
- Double-Check Your Measurements: Always measure twice to ensure accuracy. A small mistake in measurement can lead to ill-fitting blinds or shades.
- Use a Professional: If you’re unsure about any measurements, consider hiring a professional installer. They have the tools and experience to measure for blinds and shades correctly.
- Choose the Right Blinds or Shades: Not all blinds and shades are suitable for bay windows. Some styles, like cellular shades, Roman shades, and wood blinds, work exceptionally well for bay windows because they can be easily customized to fit the unique angles and shapes.
