Determine where you want your curtains to fall

Curtains & Drapes Length Options

1. Just below the ledge. This works well for smaller windows, perhanps above the kitchen sink or in the bathroom.

2. Right at the floor. Perhaps the most common curtain placement.

3. Beyond the floor. Creates a puddling effect and is used for more formal luxe looks.

Step 3: Measure For The Curtain Rod Placement

You may have the curtains or draperies of your dreams, but window hardware is an important consideration, too. Your curtain rods need to be the right length and hung in the perfect place to achieve your desired effect. Follow our measurement tricks to get the designer look you want. 

Measure window width

Show a little more window

To get the correct length curtain rod, measure the width of the window, then choose a rod 10-12" longer. 

This will allow for 5-6" rod overhang on each side, so opens curtains frame the window instead of partially cover them. 

How to measure window length

Create an optical illusion 

Make your ceilings appear taller by mounting the rod 4-8" higher than the top of the window casting.

Optimal placement is in the center between the top of the casing and the ceiling trim- not to exceed 8".

So much of the decision in choosing the right drapes and curtains depends on the style of your room and personal preferences-especially when it comes to the fabric, color and pattern choices. That's the fun part! There are so many options, it's a great idea to look at magazines and note the styles that appeal to you.
