Getting the right fit for window blinds starts with accurate measurements. Whether you’re going for an inside or outside mount, measuring properly ensures your blinds look great and function perfectly. However, it’s not always that easy to do, especially if it’s your first time. To save yourself time and money, it’s important to get this right the first time, and that’s why we’ve created this guide.
Step 1: Gather Your Tools
Before you start, make sure you have:
- A metal measuring tape (for accuracy)
- A notepad or device to record measurements
- A step stool or ladder if measuring tall windows
Metal measuring tapes are more rigid and provide more precise measurements than fabric ones. Note down all your measurements to avoid confusion later.
Step 2: Decide Between Inside or Outside Mount
The choice between an inside or outside mount affects how you measure your windows. Here’s a quick breakdown of the two options:
Inside Mount
Blinds are mounted inside the frame, giving a streamlined look and showing off the trim. This is a good option if you want a clean, minimal appearance.
Outside Mount
Blinds are mounted outside the frame, covering the entire window and often overlapping the trim. This setup provides more light control and can make windows appear larger.
Once you’ve chosen your mount style, you’re ready to start measuring.
Measuring for an Inside Mount
Measure Width
Measure the width of the window in three places: the top, middle, and bottom. Most aren’t perfectly square, especially modern tilt and turn windows, so taking three measurements ensures you catch any variations. Record the narrowest width measurement; this will be the width for your blinds, allowing them to fit inside the frame without being too tight.
Measure Height
Similarly, measure the height in three places: the left, center, and right sides. Record the longest measurement for the height, as this ensures the blinds cover the entire height.
Measure Depth
Depth is essential for inside mounts to ensure the blinds fit without protruding. Measure from the front of the frame to the back. Most Edmonton window experts provide minimum depth requirements for their selections, so confirm that your window meets those requirements.
Note
Always round your measurements down to the nearest 1/8 inch, as most manufacturers will ask for precise numbers and prefer a slightly smaller measurement for a perfect fit.
Measuring for an Outside Mount
Measure Width
For an outside mount, measure the width of the area you want the blinds to cover. Typically, this is wider than the window itself, extending a few inches beyond both sides for extra light control and privacy. A good rule of thumb is to add 2-3 inches on each side, depending on how much coverage you want.
Measure Height
Measure from the top of where you want the blinds to start (usually a few inches above the frame) to the bottom or further down if you want full coverage. Again, adding a few inches at the top and bottom provides better light control.
Note
When measuring for an outside mount, round up to the nearest 1/8 inch. For outside-mounted blinds, a slightly larger size helps to ensure full coverage of the window.
Step 3: Double-Check Your Measurements
After measuring, double-check your measurements to ensure accuracy. Blinds typically come in custom sizes, and even a small measurement error can lead to a poor fit.
Step 4: Place Your Order
When ordering, follow the manufacturer’s instructions for entering measurements, especially if they ask for specific adjustments (such as rounding up or down). For inside mounts, most manufacturers will deduct a small amount from the width you provide to ensure the blinds fit properly, so don’t add any extra space.
Tips for Accurate Measuring
- Measure each window individually: Even if frames appear the same size, small variations can occur.
- Take your time: Accurate measurements are crucial, so go slowly and double-check.
- Check for obstructions: For inside mounts, look for any obstacles inside the frame, such as handles or locks, which might interfere with the blinds.
Modern Tilt and Turn Windows Need Modern Blinds
Measuring windows for blinds might seem like a straightforward task, but attention to detail is essential. Following these steps can help you achieve a precise fit, giving your space a polished look and ensuring the coverings function smoothly. With accurate measurements and the right choice of mount, your new blinds will fit perfectly and enhance your space beautifully.
