How to Measure for Blinds & Shades
Whether you're a passionate perfectionist or seeking a stress-free solution, we've got the tips you need to measure your windows correctly.
Ready for a surprisingly painless method of getting your windows measured correctly?
Follow these 4 Easy Steps below to get started with the perfect measurements:
Step #1: Always use a steel measuring tape to record your window sizes. They're more accurate and easier to control.
Step #2: Choose an Inside Mount or Outside Mount window treatment.
Inside Mounts fit inside your window frame and look sleek and clean.
Outside Mounts are installed above and around your window frame,
which can make your windows look bigger.
Step #3: To measure the width of each window, measure in three places: across the top, middle, and bottom. Use the lowest measurement, to the nearest 1/8" inch, as the size for the width of your window.
Step #4: To measure the height of each window, measure in three places: left, middle, and right. Use the shortest measurement, to the nearest 1/8" inch, as the size for the height of your window.
Remember: All Shades will be made to your exact measurement!
