Choosing the right blinds for your home often starts with a key decision: should you go with inside mounted (installed within the window frame) or outside mounted (installed on the wall or trim above the window)? This choice impacts everything from the look and feel of your space to how well your blinds control light and provide privacy.
At International Upright Services (IUS) Shades, serving Boston, Cape Cod, Newport, Mashpee, and beyond, we help homeowners make this decision every day. Below, we break down the pros and cons of each option to help you find the best fit for your New England home.
What are Inside Mount Blinds?
Inside mounting means the blind is fastened inside the window opening, secured to the jamb or frame. This method gives a clean, tailored look. Because the blind sits within the window’s depth, it often feels integrated and minimalist.
Inside mounting is ideal when your window frame has enough depth to accommodate the blind without interference. It also lets you showcase decorative trim or molding—because the blind doesn’t cover it.
However, if the window frame is shallow or there’s molding, cranks, sensors, or hardware protruding, inside mounting may not be practical.
Pros:
- Sleek Appearance: Maintains the integrity of window trim and molding.
- Space-Saving: Keeps the window area unobstructed, allowing for full use of window sills.
- Minimalist Design: Provides a modern, unobtrusive aesthetic.
Cons:
- Depth Requirements: Requires a window frame depth of at least ¾ inch to accommodate the mounting hardware.
- Light Gaps: May allow light to seep in around the edges, especially if the fit isn’t precise.
- Obstructions: Window cranks, handles, or sensors can interfere with operation.
What are Outside Mount Blinds?
Outside mounting involves installing the blind to the wall or molding above (or around) the window opening. It overlaps the window edges and can extend beyond the frame.
This method is especially useful when the interior window depth is limited or when obstructions prevent inside mount installation. Outside mount also helps mask flaws in the window trim and provides better edge coverage, reducing light leakage.
You can even place the blind slightly above the opening to visually elevate the window—a common stylistic trick in New England homes with shorter windows.
Pros:
- Enhanced Light Control: Overlaps the window frame, reducing light gaps and improving privacy.
- Versatility: Suitable for windows with shallow frames or obstructions.
- Aesthetic Flexibility: Can make windows appear larger or taller, especially when mounted higher on the wall.
Cons:
- Coverage of Trim: Conceals window trim and molding.
- Space Considerations: Requires additional space around the window for installation.
- Visual Impact: May appear bulkier compared to inside mount options.

FAQs About Inside Mount vs Outside Mount Blinds
Q1. Which mount style gives better light control and privacy?
Outside mounted blinds generally block more light because they overlap the window edges, minimizing leaks along the sides. Inside mounts can allow fine slivers of light to pass along the edges, unless paired with side channels or complementary treatments. For strong privacy or room-darkening needs, outside mount often has the advantage.
Q2. What if my window frame is too shallow for inside mounting?
In that case, an outside mount is almost always the practical solution. Outside mounting requires little or no depth in the cavity. It also avoids interference from hardware or moldings inside the frame, providing flexibility even in tight interior spaces.
Q3. Can I mix mounting styles in different rooms?
Absolutely. Many homeowners use inside mounts in living rooms or spaces with architectural trim they wish to highlight, and outside mounts in bedrooms or media rooms for better light control. You don’t have to commit to one style across your entire house; mix them based on each window’s characteristics and function.
Choose the Right Mount With Confidence
Your choice of inside mount vs. outside mount blinds will influence both how your windows look and how well your blinds perform. Use your frame’s depth, the room’s needs, and your visual goals as your guide.
