How To Install Blinds in a Window
Installing window blinds seems straightforward until you start measuring and realize that even the smallest details matter. The difference between a clean, professional look and a crooked, gapped mess often comes down to preparation and technique.

At Read Design Window Fashions, our experts help homeowners throughout Texas understand what goes into proper blind installation, so you go into the task well prepared.
How Do You Install Window Blinds the Right Way?
The installation process begins long before you pick up a drill. Accurate measurements determine everything, and even a quarter-inch error can leave you with blinds that fit poorly or operate incorrectly.
Start by accurately measuring the width at the top, middle, and bottom of your window’s opening, then use the smallest of those measurements. Then, you take the height measurements on the left, center, and right sides.
Once you have your correct measurements, it’s time to gather your tools. You’ll typically want a pencil, level, drill, screwdriver, and measuring tape. The mounting brackets that come with your blinds will include hardware, though you may want to upgrade to stronger anchors if you’re mounting into drywall rather than wood framing.
Mark your bracket positions carefully using the level to keep everything straight.
Inside Mount Gives You a Streamlined Look
Inside mount blinds sit within the window frame, creating a clean, built-in appearance. This option works well when your window frame has enough depth to accommodate the blind headrail and when you want to showcase attractive window trim.
The finished result appears streamlined and intentional, with the blinds tucked neatly into the opening.
How To Measure Blinds for an Inside Mount
Measuring for an inside mount requires precision. Take width measurements at three points and use the narrowest of the three. Height measurements follow the same principle.
When you work with a dedicated window treatment store, like Read Design Window Fashions, we’ll use your dimensions to ensure the blinds fit flawlessly.
Outside Mount Works for Trickier Windows
Outside-mount blinds attach to the wall or to molding above and around the window frame. This approach works better for shallow window frames or when you want to make windows appear larger.
Outside mounts also help cover imperfections in the window frame or uneven openings that would be visible with an inside mount.
How To Measure Blinds for an Outside Mount
Your measurements for outside mount should include the overlap you want on each side of the window. Adding a few inches to the width and height improves light control and gives the window a grander appearance.
Mark your bracket positions at equal heights on each side of the window, using a level to verify alignment before drilling.
