How to Measure Window Blinds Like a Pro: A Comprehensive Guide Measuring for new window blinds might seem daunting, but with a little guidance, it's a straightforward process you can master. Getting accurate measurements is key to ensuring your new window treatments fit perfectly, look great, and function flawlessly. At Blinds Concept, we believe in empowering our customers with the knowledge they need to make informed decisions.
This comprehensive guide will walk you through everything, from gathering your tools to understanding crucial mounting options, so you can confidently measure your windows for blinds. Why Accurate Measurements Matter Imagine ordering beautiful custom blinds only to find they don't quite fit – too wide, too narrow, or too short. It's frustrating and can delay your enjoyment of your new window treatments. Precise measurements prevent these issues, ensuring a snug, professional look, optimal light control, and privacy.
Whether you're aiming for a sleek contemporary look or classic elegance, the right fit is fundamental. Tools You'll Need Before you begin, gather these essential tools: Steel Measuring Tape: A metal tape measure is crucial. Cloth or plastic tapes can stretch and give inaccurate readings. Ensure it's long enough for your largest windows. Pen or Pencil: To jot down your measurements. Paper or Notebook: Keep a dedicated sheet for each window, clearly labelling height and width. Step Ladder (if necessary): For high windows, safety first! The Crucial Decision: Inside Mount vs.
Outside Mount This is perhaps the most important decision you'll make before measuring, as it dictates how you take your measurements. Each option offers a different aesthetic and functional benefit. Inside Mount Blinds What it is: The blinds fit inside the window frame, flush with the casing. They sit within the window opening, offering a clean, built-in look. Pros: Sleek, integrated appearance. Highlights attractive window casings. Doesn't interfere with mouldings or trims around the window. Less light leakage at the sides if precisely measured.
Cons: Requires a minimum depth inside the window frame for mounting hardware. Check product specifications for this requirement. Slightly smaller light obstruction area compared to outside mount. If your window isn't perfectly square, you might notice small gaps. When to choose: You want a clean, minimalist look. You have beautiful window mouldings you wish to showcase. Your windows are perfectly square. You have sufficient depth within the window frame. Outside Mount Blinds What it is: The blinds are mounted outside the window frame, extending beyond the window opening.
They are mounted on the wall or trim surrounding the window. Pros: Excellent for blocking light and enhancing privacy, as they overlap the window opening. Can make a small window appear larger. Ideal for windows with shallow depths or obstructions within the frame. Can hide uneven window frames. Offers more flexibility in design and layering with drapes. Cons: Covers some of the window trim. Can protrude further into the room. When to choose: You need maximum light blockage and privacy. Your window frame depth is insufficient for inside mount.
You want to conceal an uneven or unattractive window frame. You want to make a window appear larger. You plan to layer your window treatments with curtains or drapes. Step-by-Step Measuring for Inside Mount Blinds Important Note: Always take all measurements in millimetres (mm) or fractions of an inch, and measure to the nearest 1/8th of an inch (or 1mm). Never round up or down. Always measure three times to be sure! Measuring Width: Measure the exact width of the window opening at the top, middle, and bottom. Record the smallest of these three measurements. This is your ordering width.
Blinds Concept will automatically make the necessary deductions for a perfect fit. Do NOT make your own deductions. Measuring Height: Measure the exact height of the window opening at the left, centre, and right. Record the tallest of these three measurements. This is your ordering height. Double Check for Depth and Obstructions: Measure the depth of your window frame. Ensure it meets the minimum depth requirement for your chosen blind type (this information is on the product page).
Check for any obstructions like cranks, handles, or alarm sensors that might interfere with the blind's operation when mounted inside the frame. If obstructions exist, you may need to consider an outside mount or specialty brackets. Step-by-Step Measuring for Outside Mount Blinds Important Note: When measuring for outside mount, you'll need to decide how much overlap you want around the window opening. We generally recommend an overlap of at least 2-3 inches (5-8 cm) on each side and above/below to maximize light control and privacy.
Measuring Width: Measure the exact width of the window opening, including any trim or casing you wish to cover. Add your desired overlap to this measurement. For example, if your window opening is 30 inches wide and you want a 2-inch overlap on each side, your total width would be 30 + 2 + 2 = 34 inches. Record this final measurement as your ordering width. Do NOT make any further deductions. Measuring Height: Measure the exact height of the window opening, including any trim or casing you wish to cover. Add your desired overlap to this measurement.
For example, if your window opening is 40 inches high and you want a 3-inch overlap above and below, your total height would be 40 + 3 + 3 = 46 inches. Record this final measurement as your ordering height. Do NOT make any further deductions. Pro Tip: For outside mount, decide where you want your headrail to start (e.g., 2-3 inches above the window frame) and where you want the blind to end (e.g., at the sill, or below the sill for full coverage). Measure from your chosen start point to your chosen end point.
Common Measuring Mistakes to Avoid Using a Cloth Tape Measure: These stretch and lead to inaccurate results. Always use a steel tape measure. Rounding Off: Always measure to the nearest 1/8th of an inch or 1mm. Precision is paramount. Forgetting to Measure Three Times: Always measure the width (top, middle, bottom) and height (left, centre, right) at three points. Not Specifying Inside vs. Outside Mount: This is the most crucial piece of information. Clearly indicate your mounting preference.
Assuming All Windows Are Identical: Even windows that appear to be the same size can have slight variations. Measure every window individually. Confusing Width and Height: Always double-check which measurement corresponds to width and which to height before ordering. Width is always the horizontal dimension, height is always the vertical. Making Your Own Deductions for Inside Mount: For inside mount, provide the exact window opening dimensions. We will handle the necessary deductions the blinds clear the opening.
Not Considering Obstructions: Check for window cranks, handles, or frame irregularities that might impact installation or operation. Frequently Asked Questions (FAQs) 1. How do I measure my windows for blinds correctly? To measure correctly, first decide on an inside or outside mount. For inside mount, measure the width at three points (top, middle, bottom) and take the smallest; measure the height at three points (left, centre, right) and take the tallest.
For outside mount, measure the window opening's width and height, then add your desired overlap (typically 2-3 inches on each side and above/below). Always use a steel tape measure, measure to the nearest 1/8th inch (or 1mm), and measure every window individually. 2. Should I measure in inches or millimetres? While Blinds Concept can accommodate both, we generally recommend using millimetres for greater precision, or fractions of an inch (to the nearest 1/8th). Consistency is key – stick to one unit of measurement throughout your project. 3. What if my window isn't perfectly square?
This is common! For inside mount, taking the smallest width and tallest height measurements helps ensure the blind will fit within the opening. For outside mount, an overlap of the casing can easily hide imperfections in the window frame, making it a great option for uneven windows. 4. What is the minimum depth required for inside mount blinds? The minimum depth required varies by blind type and hardware. This information is typically found on the product specifications page.
Always check this before deciding on an inside mount, as insufficient depth may necessitate an outside mount or the use of extension brackets. 5. Can I install the blinds myself after measuring? Absolutely! Most of our blinds come with detailed installation instructions, and with accurate measurements, you'll be well on your way. If you prefer professional help, Blinds Concept offers expert installation services. You can find more information on measuring and installation on our Measure & Install Guide page.
