Do My Blinds Have Enough Window Depth?

If you’re planning on buying window blinds Adelaide for your home, you’ll want to make sure that they fit. The good news is that several ways to measure what you need before buying anything. 

In this guide, we’ll go over how to take measurements and what depth of a window is required for different types of blinds.

Window Depth

The window depth is the measurement from the window sill to the window frame. It’s important to know this because it affects how far back your blinds Adelaide can be from a wall or window frame.

The minimum window depth required for blinds is 5″. The maximum is 8″, and most home builders will tell you that they can’t put in windows any larger than that without raising their prices.

The minimum distance between a wall and your blinds should be 1″ so that there’s enough room for installation.

Interior Mounting

To instal an interior mount blind, you need at least 2 inches of depth. If your window falls short of this requirement, you can still use a side or top-mount blind instead.

Here are some questions to ask yourself before choosing an interior mount:

  • Do I have enough space between my window and the wall to accommodate the mounting hardware? If not, do I want to make room by trimming away some wallboard?
  • Will it be easier for me to reach the cords if they’re mounted on either side of my window rather than below it?

 Answering this question requires considering how high or low your windows are placed in relation to their location in the room (e.g., whether there’s furniture blocking access).

Exterior Mounting

If you want your window blinds to be mounted on the exterior of your window, or if you have an exterior-mounting situation, like a slider or bay window, there are two ways this can be done: with brackets or a tilt rod.

Brackets are typically used for larger blinds that require more support and give more coverage. They’re mounted to the sides of the window frame and hold the blinds in place by pushing them into them (hence their name). 

The downside? If you use brackets it’s impossible to open your shades up all the way. And even if they do open as far as possible, they’ll probably hit each other when they get close enough together since they’re mounted out at right angles from each other (as opposed to parallel).

Tilt rods are usually smaller than brackets because they don’t need as much support—and therefore offer less coverage—but allow complete vertical movement so that when fully extended vertically, overhangs will not overlap each other and cause damage.

Will window blinds fit?

If you’re trying to decide whether your window is deep enough for blinds, the first step is to measure the window. There are two measurements you need to know:

  • The width of your window, which will be where you want to install the valance or curtains.
  • The depth of your window, which includes both sides of any trim pieces that extend out from it (such as crown molding).


You can instal blinds Adelaide on almost any window, but there are some important things to consider. The first is whether your window will be too shallow or too deep for blinds. There are also two different types of installation: interior mounting and exterior mounting.
