Should Blinds Rest On Window Sill

A window sill is the flat, shelf-like portion of the window trim located at the base of the window. It is one of the most known components of typical, traditional windows.

Window sills are a vital part of the appearance and functionality of the window. You can find them on both the interior and exterior of a window - they are suitable for housing plants or as a shelf for your decor.


Window blinds provide privacy and shade to a room. To know how far the blinds should be from your windowsill, you must first determine whether they are hung inside or outside the recess.

Aside from looking a bit odd, if the blinds are higher, even slightly above the window sill, they will allow light to enter and affect their insulating ability. However, this only works for blinds that are hung within the recess. Most blind types hung inside a recess are Venetian, vertical, or roller blinds.

Blinds that are outside the recess should ideally be longer. It would be best to have your window blinds about 10 cm longer than the distance between the headrail and the windowsill. This way, you can reduce the amount of light entering through the bottom of the blind, especially when you want it closed.

What Is A Standard Blind Size?

The length of a standard window can be between 36 and 72 inches, and the width can be between 24 and 60 inches. However, in older homes or those with custom windows, the sizes and shapes of windows can vary greatly.

If you accidentally buy very long blinds, there are methods you can execute to cut them instead of spending a lot of money on new ones.

How Long Should Blinds Be?

If you want to control the light and ensure privacy, then the length of the blinds matters. Fortunately, you can make careful measurements seamlessly by following some steps.

Measuring For Inside-Mounted Blinds

If you have an inside-mounted blind, follow these simple ways to measure them correctly.

  1. First, measure the width, which extends from the casing's inside edge to the other edge. Do this at the top, middle, and bottom spots. However, if the measurements are not equal, you need to take the smallest dimensions to guarantee that the blinds can operate freely and without interference after installation.
  2. Measure the height of the window next. The height is the distance from the sill down to the bottom edge of the upper casing. Take dimensions from three places, but retain the longest measurement this time. It is better to have longer blinds than blinds so short that they welcome unwanted lights.
  3. Lastly, measure the depth of the window. To do this, focus on the upper casing of your window. There is a flat area that looks down at the sill on its bottom side. How far down does that flat area go? That measurement can be crucial for inside-mounted blinds because many designs have a minimum depth requirement.

Consider installing outside-mounted blinds if there isn't a flat surface where you can fasten the headrail for your blinds.

Measuring For Outside-Mounted Blinds

One benefit of outside-mounted blinds is that you can install them despite difficulties in the window opening.

  1. Start by taking the width measurement of the left-to-right area of the window. Please note that you don't need to measure the whole window. Instead, measure only the parts that you want your blinds to cover. If you're into privacy and controlling light, you need to stretch up to three inches on either side of the window.
  2. Measure the length where you want to position the headrail next. Start the measurement from the headrail down to the bottom of the sill. But if you want it to hang below the sill, add a few inches.

If you're unsure about the length, always opt for a longer measurement since it will be easier to adjust longer blinds.
