Inside Mount vs. Outside Mount Blinds in Indiana

Should You Choose Inside Mount or Outside Mount Blinds?

One of the first decisions homeowners face when selecting custom window treatments isn’t choosing a color, fabric, or style—it’s deciding whether the blinds or shades should be installed inside the window frame or outside of it.

While this may seem like a small detail, the mounting style can significantly impact how your window treatments look, function, and perform.

For homeowners throughout Westfield, Carmel, Fishers, Noblesville, and surrounding Central Indiana communities, understanding the difference between inside mount and outside mount blinds can help ensure the finished result complements both the window and the room.

At In Style Blinds, this is one of the most common questions we answer during consultations. The good news is that neither option is inherently better—the right choice depends on your windows, your goals, and your design preferences.

If you’re trying to decide between inside mount and outside mount window treatments, here’s what you need to know.

What Is an Inside Mount Blind?

An inside mount blind or shade is installed inside the window frame itself.

The brackets and hardware are secured within the window opening, allowing the treatment to sit neatly inside the frame.

This installation style creates a clean, tailored appearance that many homeowners associate with custom window treatments.

Inside mounts are commonly used with:

• Custom blinds
• Roller shades
• Cellular shades
• Zebra blinds
• Roman shades
• Plantation shutters

Because the treatment sits within the frame, the window trim remains visible and becomes part of the overall design.

What Is an Outside Mount Blind?

An outside mount blind or shade is installed on the wall, trim, or molding surrounding the window rather than inside the opening.

The treatment extends beyond the dimensions of the window frame, covering a larger area around the glass.

Outside mounts are often selected when homeowners want:

• More privacy
• Better light control
• Larger visual impact
• Solutions for shallow window frames
• Coverage for specialty windows

Because the treatment extends beyond the glass, outside mounts can create the illusion of larger windows and taller ceilings.

Which Option Looks More Custom?

Many homeowners assume inside mounts automatically look more custom, but both installation methods can create beautiful results when designed correctly.

Inside mounts often create:

• Clean architectural lines
• A streamlined appearance
• A built-in look
• Greater visibility of window trim

Outside mounts often create:

• More visual drama
• Larger-looking windows
• Better fabric presence
• Enhanced design impact

For newer homes in Westfield and Carmel with decorative trim, inside mounts are often preferred because they showcase the window’s architectural details.

For rooms where maximizing coverage is important, outside mounts can create a more substantial designer look.

Which Option Provides Better Light Control?

Outside mounts typically provide better light control.

Because the treatment extends beyond the edges of the window, there are fewer gaps where sunlight can enter.

This can be especially beneficial for:

• Bedrooms
• Nurseries
• Media rooms
• Shift-worker sleep spaces
• Rooms with strong morning sunlight

Inside mounts often leave small light gaps around the edges of the treatment because the shade or blind must operate within the frame.

For homeowners seeking maximum room darkening, outside mounts are often the preferred choice.

Which Mounting Style Provides More Privacy?

Similar to light control, outside mounts generally offer more privacy.

Because the treatment covers a larger area than the glass itself, visibility around the edges is reduced.

This can be beneficial for:

• Street-facing windows
• Ground-floor rooms
• Bathrooms
• Bedrooms
• Homes with nearby neighbors

Inside mounts still provide excellent privacy, but outside mounts often create a more complete barrier.

Are All Windows Suitable for Inside Mount Blinds?

Not always.

One of the biggest factors in determining whether an inside mount is possible is window depth.

The window frame must have enough depth to accommodate the brackets and operating mechanisms required for the product.

Some older homes or specialty windows may have:

• Shallow window frames
• Crank handles
• Decorative hardware
• Structural obstructions

In these situations, an outside mount may be the better solution.

This is one reason professional measuring is so important before selecting window treatments.

Which Window Treatments Work Best With Inside Mount Installation?

Inside mounts are especially popular for:

Roller Shades

Their streamlined profile creates a clean, modern appearance.

Cellular Shades

The compact design works beautifully inside most window openings.

Zebra Blinds

The layered fabric aligns neatly within the frame.

Plantation Shutters

Custom shutters are often built directly into the opening for a seamless look.

Motorized Shades

Many motorized systems work exceptionally well with inside mounts.

For homeowners seeking a clean, architectural aesthetic, inside mounts are often the preferred choice.

Which Window Treatments Work Best With Outside Mount Installation?

Outside mounts can be ideal for:

Roman Shades

The additional fabric presence creates a dramatic, designer-inspired look.

Woven Wood Shades

Outside mounts showcase natural textures beautifully.

Blackout Shades

Improved coverage helps reduce incoming light.

Layered Window Treatments

Outside-mounted shades paired with drapery create a luxurious appearance.

Specialty Windows

Outside mounts often provide flexibility when unusual shapes or configurations are involved.

How Does Professional Measuring Help You Choose?

Choosing between inside and outside mount installation involves more than personal preference.

Professional measuring helps determine:

• Available window depth
• Mounting clearances
• Light control goals
• Privacy needs
• Window trim considerations
• Design preferences
• Product compatibility

At In Style Blinds, we evaluate each window individually to determine the best solution based on how your home functions and how you want the finished space to feel.
