Inside Mount vs Outside Mount Blinds
Choosing the right blinds can completely change how a room looks and feels. Many homeowners focus on colours, fabrics, and styles, but mounting style often gets overlooked. That decision matters just as much as the design itself.
When considering window blinds, there are typically two installation options available: inside the window recess or outside mounted. Each choice comes with its unique benefits, making the selection process dependent on factors such as your specific space, individual requirements, and personal aesthetic preferences.
This guide breaks down everything you need to know about inside and outside mount blinds. You will gain clarity, avoid costly mistakes, and feel confident about choosing the best mount for window blinds in your home.
What Are Inside Mount Blinds?
Inside mount blinds sit neatly within the window recess. They fit inside the frame and create a clean, streamlined appearance. This option works best when your window has enough depth to accommodate the blind mechanism. It allows the window frame to remain visible, which many people prefer for a neat and modern look. Inside mounts are popular in contemporary homes where minimalism plays a key role. They also pair well with decorative window frames that you may want to highlight rather than cover.
What Are Outside Mount Blinds?
Outside mount blinds are typically installed on the wall or above the window frame. They extend beyond the edges of the window, offering greater coverage. This option is ideal for windows that lack depth or have irregular shapes. It can also make a window appear larger, which is helpful in smaller rooms. Outside mounts provide better light control because they block more gaps around the edges. They also offer enhanced privacy, especially in bedrooms and street-facing rooms.
Inside vs Outside Mount Vertical Blinds: What Sets Them Apart?

When comparing inside vs outside mount vertical blinds, the difference lies in both functionality and appearance. Inside-mounted vertical blinds provide a tidy and contained look. They work well for sliding doors and large windows where space is limited. Outside-mounted vertical blinds offer more coverage. They are often chosen for better light blocking and a more dramatic visual impact. The choice depends on how much light control you need and how you want your space to feel.

Advantages of Inside Mount Blinds
Clean and Minimal Appearance
Inside mount blinds sit flush within the frame. This creates a sleek and uncluttered look that suits modern interiors.
Showcases Window Frames
Decorative frames remain visible. This adds character to your room without competing with the blinds.
Space Efficiency
Blinds do not extend beyond the window. This keeps walls clear and allows furniture placement close to the window.
Layering Options
Inside mounts work well with curtains. You can add soft furnishings without making the space feel crowded.
Advantages of Outside Mount Blinds
Improved Light Blocking
Outside mount blinds cover the entire window area. This reduces light gaps and improves room darkening.
Enhanced Privacy
Extended coverage prevents visibility through the sides of the blinds. This is especially useful in bedrooms.
Flexible Installation
Outside mounts work on shallow windows or uneven frames. They offer more freedom in placement.
Creates an Illusion of Larger Windows
Blinds mounted above and beyond the frame can make windows appear taller and wider.
How to Measure Blinds Correctly?
Accurate measurements for blinds are essential for a perfect fit. Even small errors can disrupt the overall look and function.
How to Measure Inside Mount Blinds?
- Measure the width of the window at three sections: the top, middle, and bottom. Use the smallest measurement tool to ensure the blind fits properly.
- Measure the height on both sides and in the centre. Use the longest measurement to guarantee full coverage.
- Check the depth of the window recess as well. This confirms that the blind mechanism will fit comfortably inside.
How to Measure Outside Mount Blinds?
- Measure the width of the window area you wish to cover. Add extra width on both sides of the blind measurement if you want to block light gaps.
- Measure the height from the top mounting point to where you want the blind to end. Many people choose to extend beyond the window sill for a more balanced look.
- Always double-check your measurements before placing an order.
Installation Considerations
How to Install Outside Mount Blinds with Window Trim?
- Start by marking the mounting points above the window frame. Ensure they are level and evenly spaced.
- Securely attach the brackets to the wall above the window or trim. Use appropriate fixings for your wall type.
- Once the brackets are in place, fit the blind and test its movement. Make adjustments if needed to ensure smooth operation.
- Taking your time during installation helps avoid alignment issues.
How to Install Inside Mount Blinds with Window Trim?

Choosing the Best Option for Your Space
Selecting the right mounting style depends on several factors. Consider your room layout, window structure, and desired level of light control.
Room Type Matters
Bedrooms often benefit from outside mounts due to better light blocking. Living rooms may suit inside mounts for a cleaner appearance.
Window Depth and Structure
Deep window recesses support inside mounts. Shallow frames usually require outside mounting.
Style Preferences
Minimal interiors often favour inside mounts. Bold or dramatic designs may benefit from outside mounts.
Light and Privacy Needs
Outside mounts provide more control over light and privacy. Inside mounts allow more natural light around the edges.
Common Mistakes to Avoid
- Incorrect measurements can lead to poorly-fitting blinds. Always measure carefully and verify your numbers.
- Ignoring window depth can cause installation issues. Check your space before choosing a mount type.
- Choosing style over function may lead to dissatisfaction. Balance aesthetics with practicality.
- Rushing installation can result in uneven blinds. Take your time and follow proper steps.
Enhance Your Space with the Right Blinds
Finding the right blinds involves more than just choosing a colour. Mounting style, measurements, and installation all play a role in the final result. If you want a sleek, tailored finish, inside-mount blinds may be the right choice. If you need better light control and flexibility, outside mount blinds offer strong advantages.

- Consider layering options for added style and functionality.
- Test the blind mechanism after installation to ensure smooth operation.
