Gather Your Measuring Essentials

Before you dive into the measuring process, let’s make sure you have the right tools on hand:

• Metal tape measure
• Pencil
• Notepad
• Level (Optional)

Having these simple tools readily available will streamline the measuring process and set you up for success in achieving a perfect fit for your new blinds.

Inside Mount vs. Outside Mount

Choosing the right mount for your blinds is crucial for aesthetics and functionality. Let’s explore the two primary options:

Inside Mount

Inside mount blinds are installed within the window frame, offering a sleek and streamlined appearance. They create a clean, minimalist look that blends seamlessly with your window, making them a popular choice for modern and contemporary interiors.

Outside Mount

Outside mount blinds are installed on the wall or ceiling above the window frame, extending beyond the window opening on all sides.

This type of mount offers several advantages:

• Covers window trim
• Maximizes light blockage
• Creates the illusion of larger windows

Factors to Consider

When deciding between inside and outside mount, keep these factors in mind:

• Window depth: The inside mount requires sufficient depth within the window frame to accommodate the blinds’ headrail and mechanisms.
• Desired look: Choose an inside mount for a sleek, integrated look or an outside mount for a dramatic effect.
• Light control and privacy: Opt for an outside mount if you need maximum light blockage and privacy.
• Window style: Some window styles, like bay windows or those with protruding handles, may be better suited for outside mount.

Ultimately, the best mount for your blinds depends on your personal preferences and the specific characteristics of your windows. Consider the factors above and consult a window treatment expert if you need further guidance.

How to Measure Windows for Blinds: Inside Mount

Here’s how to measure for inside mount blinds:

Step-by-Step Instructions

1. Measure width:
   • Using your metal tape measure, measure the window opening width at the top, middle, and bottom.
   • Record all three measurements on your notepad.
   • The smallest of these three measurements will be your final width for the blinds.
2. Measure height:
   • Measure the window opening height at the left, middle, and right sides.
   • Record all three measurements on your notepad.
   • The smallest of these three measurements will be your final height for the blinds.
3. Deduct for a snug fit:
   • Subtract 1/4 inch from both your final width and height measurements. This ensures a snug fit within the window frame and prevents the blinds from rubbing or binding.

Tips for Accuracy

1. Use a metal tape measure: Metal tape measures offer greater precision than cloth or plastic ones, which can stretch and lead to inaccurate measurements.
2. Measure to the nearest 1/8th of an inch: Blinds are manufactured precisely, so accuracy is key. Measuring the nearest 1/8th of an inch will ensure the best fit.
3. Keep the tape measure level: Hold the tape measure horizontally and vertically to avoid skewed measurements.
4. Double-check: It’s always a good idea to double-check your measurements to ensure accuracy.

Measuring for Outside Mount Blinds

If you’ve opted for outside mount blinds, here’s how to measure accurately.

Step-by-Step Instructions

1. Decide on Overlap:
   • Determine how much you want the blinds to extend beyond the window frame on each side. A typical overlap is 2-3 inches, but you can adjust this based on your preferences and the look you’re aiming for.
2. Measure Width:
   • Measure the width of the area you want the blinds to cover. This includes the window frame itself plus the desired overlap on both sides.
   • Record this measurement as your final width for the blinds.
3. Measure Height:
   • Determine the height you want the blinds to reach, including the window frame and any additional coverage you’d like above and below.
   • Record this measurement as your final height for the blinds.

Additional Tips

1. Mind the obstructions: Note any obstructions around the window, such as handles, cranks, or light fixtures. Make sure your blinds won’t interfere with their operation.
2. Window operation: Ensure the blinds won’t obstruct the window’s opening and closing. For casement windows, consider the direction they open and how the blinds will be positioned.

Special Considerations

While measuring standard windows is relatively straightforward, some window types require special considerations.

Bay or Corner Windows

These unique window configurations often involve multiple angles and frames. To ensure a perfect fit, you’ll need to take separate measurements for each window section. It’s highly recommended that you consult a professional window treatment specialist for accurate measurements and installation guidance.

French Doors

French doors typically combine a door panel with a window section. When measuring for blinds, treat each section separately. Measure the door panel as you would a standard door, and measure the window section as you would a standard window, considering whether you prefer an inside or outside mount.

Skylights

Due to their unique placement and accessibility challenges, skylights require precise measurements and specialized installation techniques. To ensure a safe and secure installation, it’s best to leave this task to the professionals.
