Outside vs. Inside Mount Window Coverings: Which Is Right for Your Home?
When it comes to choosing new window coverings, one of the first decisions you’ll need to make is how they will be mounted: on the inside of the window frame or the outside of it. This choice not only affects how your coverings look but also how they function in your space. Both options have their own benefits, and the right one depends on your windows, your style, and your goals.
Let’s break down the differences so you can make the best choice for your home.
Inside Mount Window Coverings
What they are: Inside mount coverings are installed neatly within the window frame, sitting with a small space between the window treatment and the glass. NOTE: you MUST have this space to allow for air flow. Black mold is our enemy! If there is not enough air flow, condensation occurs and cannot dry out – black mold can then spread faster than covid at a concert 🤪
Why homeowners love them:
- Clean, tailored look – Perfect if you love a minimalist or modern design.
- Show off trim & molding – Keeps the beautiful details of your window visible.
- Space-saving – A great option for smaller rooms where you want to avoid anything protruding too far into the space.
Things to consider:
- Your windows need to have enough depth to fit the product properly.
- If your window frames aren’t square or have obstructions, gaps can occur, lending to very obvious uneven bands of light coming from the sides.
- Operating system can also affect the size of the light gaps on the side of the blind. This affects different types of window coverings more than others. Example: Roller blinds have an end mount bracket system so the gaps are bigger.
Outside Mount Window Coverings
What they are: Outside mount coverings are installed above the window frame or on the wall, extending beyond the glass and frame. NOTE: you must open your window coverings daily. This limits even more air flow than inside mounted blinds/shades.
Why homeowners love them:
- Enhanced light control – Excellent for bedrooms and media rooms where blocking out light is a must.
- Creates the illusion of larger windows – Mounting higher and wider can make windows (and ceilings) appear bigger.
- Hides imperfections – Ideal if your window frames are shallow, uneven, or not square.
- Flexibility – Works for almost any window type, including patio doors and specialty shapes.
Things to consider:
- Since they extend beyond the frame, they may not offer the same “built-in” look as an inside mount.
- They require a little more wall space around the window for proper installation.
- Tends to be the preferred choice of Interior Designers for certain window treatments, for example Roman Blinds
Which One Should You Choose?
The decision really comes down to your priorities:
- If you want a sleek, minimal look that highlights your window trim → go with inside mount.
- If you need maximum light control, coverage, or flexibility → outside mount may be the better option.
- Many homeowners even mix both styles throughout their homes depending on the room and purpose.
Why Professional Guidance Matters
While you can measure and order on your own, the truth is that fit is everything when it comes to window coverings. A mis-measurement of even a quarter inch can mean the difference between a flawless installation and a frustrating redo.
That’s why working with a professional is your best investment. We’ll help you decide whether inside or outside mount works best for each window, ensure accurate measurements, and recommend the right products to suit your space and lifestyle.
Final Word
Choosing between inside and outside mount window coverings may seem like a small detail, but it has a big impact on the style and function of your space. The good news? There’s no wrong choice—only the right choice for you and your home.
