Where should you hang blinds?
Regarding this, where should blinds be hung?
You can either mount your blinds inside or outside of the casing. Hanging the blinds outside means your window look bigger but when you hang your blinds inside, your window looks slimmer. When you need to mount your blinds outside, measure along the outside edges of the casing that surrounds the window.
Also to know is, do blinds go inside or outside the window?
Inside mounted blinds and shades will give you the cleanest look. That is because they fit inside the window frame, and can be mounted as deep or as shallow as you like. Outside mounted blinds and shades give the flexibility of choosing almost any window covering for any situation.
In most cases blinds look and work the best when they rest on the window sill. No one is ever going to notice extra 1/2" of length and this keeps them from blowing in a slight breeze. If you prefer for the blinds not to touch the windowsill, you should deduct 1/4".
