How to Choose Between Inside Mount vs. Outside Mount Roman Shades: What to Consider

Roman shades are a versatile and stylish window treatment option, but when it comes to installation, one key decision can make all the difference: inside mount versus outside mount. Whether you're looking for a sleek, minimalist look or need to accommodate unique window shapes, both options offer distinct advantages. In this post, we'll guide you through the factors to consider when deciding which mounting option is best for your windows and home design.


When Should You Choose Inside Mount Roman Shades?

Inside mounted Roman shades are installed within the window frame, offering a streamlined, built-in appearance. Here are some scenarios where inside mounts are ideal:

  • Showcasing Decorative Window Trim: If you have beautiful, decorative molding or window casings that you don’t want to hide, inside mounts are the perfect solution. The shades sit within the window frame, highlighting your window's design rather than covering it.
  • Maximizing Window Design: For rooms where the window itself is a design feature—whether it’s a painted frame or unique wallpaper—inside-mounted shades can help separate the fabric of the Roman shade from the walls and frame, enhancing the overall aesthetic.
  • Limited Space Above the Window: Inside mounts are ideal for windows with little space above, as they don't require the extra 4 inches of wall space needed for outside mounts.
  • Small Windows: Inside mounts are a great choice for smaller windows as they don't take up additional visual space, making the room feel more open and uncluttered.

However, inside mounts come with some restrictions:

  • Depth of the Window Frame: Inside mounts require at least 1.5” of flat surface on the window frame for proper installation. If your window frame is too shallow or irregular, inside mounts may not be possible.
  • Light Gaps: If your window is not perfectly square, you may notice light gaps between the shade and the window frame. This could be problematic if you need complete blackout conditions in rooms like bedrooms or media rooms.

When Should You Choose Outside Mount Roman Shades?

Outside mounted Roman shades are installed on the wall or trim outside the window frame. This mounting option offers several unique benefits and is ideal in the following scenarios:

  • Shallow or Irregular Window Frames: If your windows have shallow or uneven frames, outside mount Roman shades can help cover imperfections and offer a cleaner, more polished look.
  • Maximizing Light and Height: Mounting Roman shades a few inches above the window frame creates the illusion of taller windows and allows more natural light to enter when the shades are fully raised. This is especially useful for shorter windows or spaces where you want to let in as much sunlight as possible.
  • Showcasing Fabrics and Prints: If you’re using a fabric with a bold or beautiful pattern, an outside mount can showcase more of the design. By mounting the shades higher, you can display more of the fabric while making the windows feel taller.
  • Windows with No Trim: For windows that don't have any decorative trim or casing, outside mounts can provide a more structured and complete look, as they don’t rely on the window frame to create a clean appearance.

However, outside mounts also have considerations:

  • Visible Hardware: The mounting brackets and hardware are visible, which may not be ideal if you prefer a completely clean look.
  • Blocking Window Trim: If you have intricate or expensive window trim, outside mounts may obscure the design, which could be a downside if you want to highlight the architectural details.

How to Determine Which Mounting Option Is Best for You

When choosing between inside and outside mount Roman shades, there are several factors to consider:

  • Window Depth: Measure the depth of your window frame. If it’s at least 1.5” deep, inside mounts are a viable option. Shallow or uneven frames are better suited for outside mounts.
  • Aesthetic Preferences: Inside mounts work well if you want a sleek, minimalistic look that doesn’t interfere with window trim or molding. Outside mounts are perfect if you want to showcase your window treatment fabric or create the illusion of taller windows.
  • Lighting Needs: If you require more light control, outside mounts can be adjusted to cover more of the window and block out light. Inside mounts may leave light gaps, especially if your window isn’t perfectly square.
  • Space Above the Window: If you have at least 4 inches of space above your window, outside mounts are a good option. If not, inside mounts will work better, especially in smaller spaces.


Conclusion: Making the Right Choice for Your Home

Both inside and outside mount Roman shades offer unique benefits, and the best choice depends on your window's characteristics, your design preferences, and your functional needs. Whether you’re trying to showcase beautiful trim, maximize light, or create a sleek, minimalist look, there’s a Roman shade mounting style that fits your space perfectly.

Frequently Asked Questions (FAQ):

What’s the difference between Inside Mount and Outside Mount Roman Shades?
Inside Mount Roman Shades are installed inside the window frame, offering a clean, built-in look. This style is ideal for showcasing decorative trim or when you want a minimalistic design. Outside Mount Roman Shades are installed on the wall or trim outside the window frame, making them perfect for hiding imperfections, creating the illusion of taller windows, or when the window frame isn’t deep enough for an inside mount.

Are Inside Mount Roman Shades suitable for all windows?
Inside Mount requires the window frame to have enough depth—typically at least 1.5 inches. If the frame is too shallow or irregular, Inside Mount may not be a good option, and Outside Mount would be more appropriate.

Will Outside Mount Roman Shades cover my window trim?
Yes, Outside Mount Roman Shades will cover the window trim and decorative casing. This can be beneficial for hiding imperfect window frames or creating a balanced look, especially in older homes. However, if you want to highlight your window trim, Inside Mount may be a better choice.
