Inside vs. Outside Mount Blinds: What’s the Difference?

When you’re selecting new window blinds, one of the first choices you will make is whether to install them as an inside mount or an outside mount. While it may seem like a small detail, the decision between inside versus outside mount blinds can greatly impact both style and function.

Inside mount blinds are installed within the window’s frame. The blinds fit neatly inside the casing, creating a polished look that feels built in.

Some benefits of inside mount window treatments include”

• Enjoying a clean and streamlined appearance that highlights the trim and creates a minimal look.
• Saving on space, as the blinds sit inside the frame without extending into the room.
• Layering other window treatments, such as drapery panels or valances, is easier.
• Reducing side light gaps since the blinds are closer to the glass.

An inside mount requires enough frame depth to hold the headrail and slats. If your window frame is shallow, the blinds may stick out slightly, disrupting the smooth and seamless fit.

Outside mount window treatments are attached to the wall or the molding around the window. Instead of sitting inside the frame, the blinds extend beyond the opening and cover more surface area.

Here are some advantages of having outside mount window treatments:

• Blocking more incoming light from the sun and streetlights while providing more privacy since they cover a larger area.
• Hiding trim imperfections or uneven frames.
• Creating the impression of a taller or broader window when mounting blinds above or wider than the opening.
• Pairing well with a frame depth that’s too shallow for an inside mount.

An outside mount will project slightly farther into the room and may cover the trim. You’ll also need enough space above and beside the window for the brackets and headrail.

When comparing window blinds inside versus outside mount, the choice comes down to your goals.

An inside mount is often the best option if you want a sleek and minimal look that highlights the window frame. If you need maximum privacy, more light control, or have shallow frames, an outside mount may suit your space better.

Either way, custom blinds ensure a precise fit. With professional measuring and installation, your blinds will operate smoothly and look like they belong exactly where they are.
