TL;DR this is a guide to measuring windows for window film. This is the first step to take when ordering window film from Concord Window Film.
We can all agree that windows are an essential and desirable architectural element in homes. They let the outdoors in and provide natural light which is prized in homes for ambiance and health. But sometimes, your windows can turn into a problem when they let in too much of the sun’s energy.
If you’ve been considering solar control window film to keep your home or office cool, comfortable, and energy-efficient, you’re already on the right track. But before you can enjoy the benefits of our top-quality Concord Window Film, there’s one crucial step: measuring windows for window film accurately. Don’t worry—it’s easier than you think! In this guide, we’ll walk you through the process of measuring windows for window film so you can get it right the first time.
Solar control film is a game-changer—it blocks harmful UV rays, reduces glare, and helps lower your energy bills by keeping indoor temperatures stable. Even the U.S. Department of Energy classifies solar control window film as an energy efficient window covering! But to get that perfect fit and seamless installation, good measurements are key. Too small, and you’ll have gaps; too large, and you’re wasting material.
At Concord Window Film, we want your experience to be as smooth as possible, so we have a foolproof method of measuring your windows for a professional finish. So, grab a tape measure, a notepad, and let’s get started!
Here’s how to measure your windows like a pro:
You don’t need anything fancy—just a tape measure a pen or pencil, and paper to jot down your numbers. A step ladder might come in handy for taller windows, too.
Start by measuring the width of the glass pane—not the frame. Place your tape measure from the left edge of the glass to the right edge. For the most accurate fit, measure in three spots: near the top, middle, and bottom. Windows aren’t always perfectly square, so record the largest of these measurements to ensure your film fits perfectly. Write it down in inches.
Next, measure the height of the glass from top to bottom. Again, take three measurements: one on the left, one in the center, and one on the right. Use the largest number to account for any slight variations in the window’s shape.
Before you move on, double-check your measurements. It’s a simple step that can save you a headache later. If you’re measuring multiple windows, label each set of dimensions (e.g., “Living Room East,” “Office North”) to keep everything organized.
Next you should take your dimensions and add an extra inch to both the width and height.
This is how pros install film to ensure a nice tight fit. Not all windows are perfectly plumb and it is easier to make sure the piece of film is the right size by fitting it while it is on the window. You don’t want to end up with a gap between the film and the window frame that will let in light.
Our Concord Window Film is easy to work with, so even first-timers can achieve a professional look.
For angled windows the process is slightly different. Measure the width at its longest point (typically the base or top, depending on the angle) and the height at its longest point (usually the tallest vertical edge).
We only cut and ship film in rectangles – so we need the longest dimensions to ensure your film fits.
To help you with measuring windows for window film, we’ve put together a Window Film Calculator. We use this when quoting jobs for customers to help organize your measurements and calculate the sizes that will work for you. Simply enter your measurements into the white cells on the sheet and the calculator will determine the piece of film you need for each window.
You can download the spreadsheet here. Once completed, feel free to send your measurements to us at support@windowfilm.com – and we can provide a quote with all of your options for purchasing film with us.
