Inside vs. Outside mount - What's the Right Answer?

When it comes to installing window blinds or shades, one of the most important decisions you'll make is whether to choose an inside mount or an outside mount. Both methods have their own set of advantages and disadvantages, and the best choice depends on your specific needs and the characteristics of your windows. In this article, we'll explore the pros and cons of each installation method to help you make an informed decision.

Inside Mount


  1. Clean and Neat Appearance: Inside mount installations offer a sleek and streamlined look. The blinds or shades fit neatly within the window frame, providing a more integrated and modern appearance.
  2. Space-Saving: Since the blinds or shades are installed inside the window frame, they don't protrude into the room. This is especially beneficial for smaller rooms where space is at a premium.
  3. Enhanced Architectural Features: If your windows have beautiful trim or molding, inside mounts allow these features to remain visible, adding to the overall aesthetic appeal of the room.


    1. Limited Light Control: Inside mounts can sometimes allow light to seep in around the edges, especially if the window frame is not perfectly square. This can be a drawback if you need total darkness, such as in a bedroom or media room.
    2. Fit Restrictions: Inside mounts require precise measurements to ensure a proper fit. If the window frame is not deep enough, or if there are obstructions like window cranks or handles, an inside mount may not be feasible.
    3. Installation Challenges: Installing inside mounts can be more challenging, as it requires careful measurement and alignment. Any miscalculations can result in a poor fit or the need for adjustments.

      Outside Mount


      1. Better Light Control: Outside mounts cover the entire window and frame, offering better light control and privacy. This is ideal for rooms where you need to block out as much light as possible.
      2. Easier Installation: Outside mounts are generally easier to install because they don't require as precise measurements. They can also cover any imperfections or gaps around the window frame.
      3. Versatile Fit: Outside mounts can be used on virtually any window, regardless of size or shape. They are also suitable for windows with shallow frames or obstructions that would prevent an inside mount.


        1. Bulkier Look: Outside mounts tend to be more noticeable and can create a bulkier appearance. They extend beyond the window frame and may cover up decorative trim or molding.
        2. Space Considerations: Since outside mounts protrude into the room, they can take up more space and may interfere with furniture or decor placed near the window.
        3. Potential for Damage: Installing outside mounts can sometimes damage the wall or trim, especially if the mounting hardware is not properly secured.


            Making the Right Choice

            When deciding between inside and outside mounts, consider the following factors:

            • Window Depth: Measure the depth of your window frame. If it's less than the recommended depth for an inside mount, you may need to opt for an outside mount.
            • Light Control Needs: If blocking out light is a priority, an outside mount may be the better choice. For a cleaner look with less concern about light seepage, an inside mount is ideal.
            • Aesthetic Preferences: Consider the overall look you want to achieve. Inside mounts offer a more integrated look, while outside mounts provide a more substantial, framed appearance.
            • Installation Skills: If you're a DIY enthusiast, inside mounts require more precision and careful measurement. Outside mounts are generally easier to install and adjust.

              Ultimately, the decision between inside and outside mounts comes down to your specific needs and preferences. Both methods have their own unique benefits and can enhance the look and functionality of your windows.


              Choosing the right mount for your window blinds or shades is a crucial step in creating the perfect look for your home. By weighing the pros and cons of inside and outside mounts, you can make an informed decision that meets your practical needs and aesthetic goals. Whether you prefer the sleek, unobtrusive look of an inside mount or the superior light control and versatility of an outside mount, both options can provide a stylish and functional solution for your windows.
