Bay windows add charm and light to a room, but measuring for blinds can feel tricky. This comprehensive guide simplifies the process, ensuring your new blinds fit perfectly and enhance your beautiful bay window. We'll cover everything you need to know, from identifying your window type to choosing the right blind style.

Understanding Bay Window Types

Before you grab your measuring tape, let's clarify the different types of bay windows:

• Three-sided bay window: The most common type, featuring three windows joined at angles.
• Five-sided bay window: Similar to a three-sided bay, but with two additional smaller windows flanking the main central window.
• Circular bay window: A curved window configuration which presents a unique measuring challenge.

The measuring process will vary slightly depending on your specific bay window type, but the fundamental principles remain the same.

Choosing the Right Blind Style for Your Bay Window

The style of blind you choose greatly influences the measuring process. Some popular options include:

• Cellular Shades: Excellent insulators, offering energy efficiency. Their pleated design can accommodate angled windows.
• Roller Shades: Simple, versatile, and available in various fabrics and opacities. Easy to measure and install.
• Roman Shades: Elegant and stylish, they offer a tailored look. They can be adapted to angled windows.
• Vertical Blinds: Ideal for wide windows, offering excellent light control. Their vertical slats can follow the angle of your bay window.

No matter your chosen style, careful measurement is key to a perfect fit.

How to Measure for Bay Window Blinds: A Step-by-Step Guide

Step 1: Determine Your Window Type and Measure Each Pane Individually

Start by identifying your bay window type (three-sided, five-sided, or circular). Then, measure each individual window pane separately. Record the width and height of each pane. Use a flexible measuring tape to accurately capture the angles.

Step 2: Decide on Inside Mount vs. Outside Mount

• Inside Mount: Blinds are fitted inside the window recess. This is generally more aesthetically pleasing but limits the amount of light blockage. Measure the width and height of the recess for each window pane.
• Outside Mount: Blinds are mounted on the wall or frame outside the window recess. This allows for greater light control but can make the window appear smaller. Measure the width and height of the area where you want the blinds to cover.

Step 3: Account for Angles and Curves

This is where bay windows become unique.

• Three- and Five-Sided Bay Windows: You'll likely need separate blinds for each window pane. Measuring each individually is crucial, paying attention to the angles where the panes meet.

• Circular Bay Windows: These require more careful consideration. Often, bespoke blinds are needed, and professional measurement is highly recommended.

Step 4: Measure the Total Width of the Bay Window

To determine the overall width of your bay window for blinds that cover the entire bay, measure the combined width of all window panes, including any spaces between them. Add a few extra inches for proper overlap or ease of installation.

Step 5: Measure the Height of the Bay Window

Determine the overall height of your bay window. Measure from the top of the window frame to the bottom for an inside mount. Measure from the point where you want the blinds to start to the bottom for an outside mount.

Step 6: Consider Overlap and Installation

For a neat, professional finish, ensure there’s sufficient overlap between blinds. Consider your chosen installation type (inside or outside mount) during measurement. The added inches provide extra room for the installation.

Step 7: Review Your Measurements

Double-check all measurements before ordering to avoid costly mistakes. It’s a good idea to write down your measurements in a clear, organized manner.
