Accurate measurements are crucial for a perfect fit when it comes to adding blinds to your windows. Whether you’re upgrading your home’s aesthetics or seeking privacy, following a precise measuring process ensures that your blinds not only look great but also function effectively. 

This step-by-step guide will walk you through the process of measuring your windows for blackout blinds, helping you avoid common pitfalls and achieve a professional result.

Step 1: Gather Your Tools

Before you start measuring, gather the necessary tools:

1. A steel tape measure (plastic or cloth measures are not recommended for accuracy)

2. A pencil and paper for notes

3. A step ladder (if needed)

4. A level (optional, but helpful for ensuring accuracy)

Step 2: Decide on Mounting Type

Determine whether you want to mount your blinds inside or outside the window frame:

1. Inside Mount: The blinds will fit within the window frame. This option creates a cleaner look and allows for more space on your windowsills.

2. Outside Mount: The blinds will extend beyond the window frame, covering part of the wall. This option can make your windows appear larger and provide better light coverage.

Step 3: Measure for Inside Mount

Measure the Width:

1. Using your tape measure, measure the width of the window opening in three places: the top, middle, and bottom. This accounts for any variations in window size. Note the narrowest measurement.

2. Measure from the left to the right side of the window frame. Be sure to measure from the wall to the inside edge of the window frame for a precise fit.

Measure the Height:

1. Measure the height of the window opening in three places: the left side, middle, and right side. Note the longest blackout blinds NZ measurement.

2. Measure from the top of the window frame to the bottom. Ensure you include any window trim or moulding in this measurement.

Check for Depth:

1. Measure the depth of the window frame to ensure that the blinds will fit properly. This is particularly important for inside mounts to ensure that the blinds do not protrude out or get stuck.

Step 4: Measure for Outside Mount

Measure the Width:

1. Measure the width of the area where you want to mount the blinds. Extend your measurement beyond the window frame on both sides to ensure full coverage and to block out more light.

2. Add at least 1 to 2 inches on each side of the window frame for a complete cover.

Measure the Height:

1. Measure the height from the top of where you want to mount the blackout blinds to the desired length. You can extend the measurement beyond the window frame on the top and bottom to enhance light coverage and privacy.

2. Consider adding extra length to cover any gaps and to ensure the blinds extend below the window frame sufficiently.

Check for Obstructions:

1. Ensure there are no obstructions such as handles, vents, or other elements that could interfere with the blinds’ operation. Measure around these obstructions to ensure a proper fit.

Step 5: Record and Double-Check Measurements

Accurate measurements are essential, so double-check each measurement to ensure correctness. Record your measurements clearly, noting whether they are for width or height and if they are inside or outside mount. A small error can lead to blinds that don’t fit properly, so taking the time to double-check will save you from potential issues later.

Step 6: Choose Your Blinds

With your measurements in hand, you can now choose the right blinds for your windows. Consider factors such as material, colour, style, and functionality to match your room’s décor and your needs.

Step 7: Order and Installation

Once you’ve selected your blackout blinds NZ, you can place your order with the measurements you’ve taken. Most manufacturers or retailers will ask for precise measurements to ensure a custom fit. Upon receiving your blinds, follow the installation instructions provided or consult a professional installer if needed.

Final Words

Measuring windows for blackout blinds may seem like a daunting task, but with careful attention to detail and following this step-by-step guide, you can achieve a perfect fit and enhance the functionality and appearance of your windows. 

Accurate measurements not only ensure that your blinds fit properly but also contribute to the overall aesthetic and comfort of your home. By taking the time to measure correctly, you’ll be rewarded with a stylish and functional window treatment that complements your space.
