Otherwise, you risk ending up with treatments that are either too small or too large for your windows. Measuring for blinds or other window treatments is relatively easy and only requires a few simple tools. First, you’ll need a steel tape measure in order to obtain the width and height of your window. Second, you’ll need a level in order to ensure that your treatment will hang straight.

Finally, you may also want to use a pencil or a piece of chalk in order to mark some of your measurements. With these simple tools, you’ll be well on your way to choosing the perfect blinds or window treatments for your home.

Inside mount vs outside mount

When measuring for window treatments, it’s important to know whether you need an inside mount or an outside mount. An inside mount means the treatment will be mounted on the inside of the window frame, while an outside mount means it will be mounted on the wall above the window.

The type of mount you need will depend on the squareness of your window opening, the depth of your window, and the type of window treatment you want. For example, if you have a shallow window frame, you may need an outside mount to ensure that the treatment doesn’t interfere with the opening and closing of the window. Conversely, if you want a treatment that hangs down from the top of the window opening, you’ll need an inside mount.

This one is simple, just measure up to the edge of the flat area of the architrave for both the width and the drop.
 
As always, measure in 3 places for both and use the smallest measurement. Do not add anything to your measurements.
