How to Measure for Window Blinds: A Guide

Welcome to our article on how to measure for window blinds! Whether you’re a homeowner, a designer or someone who is looking to switch up their window coverings, having the right measurements is crucial for ensuring a proper fit. In this article, we’ll go through 12 steps that will help you measure your windows accurately, as well as share some additional tips and tricks to make the process easier.

Steps to Measuring for Window Blinds

Step 1: Choose Your Mounting Type

Before you start measuring, you’ll need to decide whether you want to mount your blinds inside the window frame or outside of it. Measuring for inside mounts will require precise measurements, while outside mounts will require more space and a wider panel. Measure the depth of your window frame to determine which mounting type works best.

Step 2: Measure Your Window Width

Take the inside measurement of your window frame in three locations – the top, middle and bottom of the window. Record the narrowest measurement as your window width. If you’re using an outside mount, measure the width of the area you want your blinds to cover.

Step 3: Measure Your Window Height

Take the inside measurement of your window frame from the top to bottom of the window. If you’re using an outside mount, measure the height of the area you want your blinds to cover.

Step 4: Measure for Window Depth

Measure the depth of your window frame to ensure that your blinds will fit flush against the wall. If you’re using an outside mount, add 2-3 inches to the depth measurement for extra clearance.

Step 5: Decide on Your Bracket Placement

Inside mounts require brackets to be installed inside the window frame. Measure the distance from the top of your window frame to the top of the bracket location and record it. For outside mounts, measure the distance from the top of the window frame to where you want the top of the bracket to be.

Step 6: Adjust for Obstructions

If you have obstructions like handles or cranks on your window frames, measure their depth and add it to the necessary measurements. Make sure to take into account any uneven surfaces, such as moulding or trim.

Step 7: Consider Light Gaps

Light gaps can be caused by the type of mounting or track system you use. To prevent this, measure the space between your window frame and the wall and add it to the width measurement. For outside mounts, add the gap measurement to the width and height measurements.

Step 8: Decide on Your Panel Overlap

If you want your blinds to overlap in the middle, you’ll need to decide on the desired overlap measurement. Usually, 1-2 inches is sufficient, but it depends on your personal preference.

Step 9: Verify Your Measurements

Double-check all your measurements to make sure they are accurate and match the mounting type you’ve chosen. It’s always better to take time to remeasure than to end up with blinds that don’t fit properly.

Step 10: Decide on Control Placement

Blinds can be controlled from either side, so decide where you want your controls to be. Measure the distance from the top of the window frame to the location of your control, and record it.

Step 11: Review Your Order

Before placing your order, read through the manufacturer instructions carefully to ensure that you’ve provided all the necessary measurements. Double-check that you’ve chosen the right mounting type and made note of any special instructions.

Step 12: Install Your Blinds

Once your window blinds have arrived, it’s time to install them! Follow the manufacturer’s instructions carefully, and make any necessary adjustments to achieve a perfect fit.

Tips and Tricks

Tip 1: Use a Steel Tape Measure

When measuring for window blinds, it’s important to use a steel tape measure, which is more sturdy and accurate than a cloth tape measure.

Tip 2: Measure Twice, Cut Once

Take your time and measure each step twice to ensure that you have accurate numbers.

Tip 3: Order Samples

If you’re unsure about the color or material of your window blinds, order samples before making a final purchase.

Tip 4: Check for Warranty

Make sure you understand the manufacturer warranty before making a purchase. It’s better to be informed of any repairs or replacements before you need them.

Tip 5: Don’t Forget to Account for Light Gaps

Light gaps can ruin the look and functionality of your window blinds, so be sure to measure the gap between your window frame and the wall.

Tip 6: Be Mindful of Your Mounting Type

Inside mounts require precise measurements and outside mounts will require more space. Consider which mounting type works best before measuring.

Tip 7: Think About Panel Overlapping

Decide on how much overlap you want between your window blinds and measure accordingly.

Tip 8: Measure for Obstructions

Don’t forget to take into account any obstructions, such as handles or cranks on your window frames.

Tip 9: Verify Your Order

Before ordering your window blinds, double-check all of your measurements and make sure you’ve selected the right mounting type.

Tip 10: Follow Manufacturer Instructions

When installing your window blinds, follow the manufacturer’s instructions carefully to ensure they’re properly installed.

We hope this article has helped you to measure for window blinds accurately. Remember to take your time, double-check your measurements, and follow the manufacturer’s instructions for a perfect fit.
