How to Measure Curtains for Double Windows

Measuring curtains for double windows might seem daunting at first, but with the right steps and a little patience, you can achieve a perfect fit. Double windows, also known as French doors or patio doors, have two panes of glass, often with a small gap in between. To ensure your curtains hang beautifully and function correctly, accurate measurements are crucial. Let's dive into the process, step by step.

Before you start, gather your tools: a measuring tape, a pen, and a notepad. Also, have your curtain rod and curtain header (the top part of your curtain) ready. This guide assumes you'll be using a standard curtain rod with a header that can be adjusted to fit your window width.

Measuring the Width

The width of your curtains should be determined by the size of your window and the look you want to achieve. For double windows, you have two main options: one curtain for both panes or two separate curtains.

One curtain for both panes is simpler and can create a cohesive look, especially if your windows are the same size. To measure, you'll need the width of both panes combined. Use your measuring tape to find the width of each pane, then add them together. Don't forget to account for any overlap you want between the two curtains. For example, if each pane is 24 inches wide, and you want a 4-inch overlap, your total width would be 52 inches.

Measuring for One Curtain

If you choose one curtain for both panes, follow these steps:

• Measure the width of the first pane.
• Measure the width of the second pane.
• Add the two widths together and add any desired overlap (e.g., 4 inches).

Measuring for Two Curtains

If you prefer two separate curtains, measure each pane individually. This can create a more tailored look, especially if your panes are different sizes. Just ensure your curtain rod is long enough to accommodate both curtains.

Once you have your width measurement, add 4 to 6 inches to each side to account for the curtain header and any pleating or gathering you want. This will give you the total width you need to order or make your curtains.

Measuring the Drop

The drop, or length, of your curtains is just as important as the width. It determines how much of your window and wall the curtains will cover. Standard curtain lengths are 63, 84, or 96 inches, but you can also order custom lengths.

For double windows, you typically want the curtains to cover the entire window, including the top and bottom, and extend a few inches on either side. This can help insulate your room and create a more polished look.

Measuring for Inside Mount

If your curtain rod will be mounted inside the window frame (an inside mount), measure from the top of the window frame to the floor. This will give you the exact length you need for your curtains. Don't forget to subtract the length of your curtain header from this measurement to ensure your curtains touch the floor.

Measuring for Outside Mount

If your curtain rod will be mounted outside the window frame (an outside mount), you'll need to measure from the top of the curtain rod to the floor. This will give you the length of your curtains, including the header. If you want your curtains to touch the floor, subtract the length of your curtain header from this measurement.

Remember, if you want your curtains to puddle on the floor (a popular look for formal or elegant rooms), you'll need to add several inches to your measurement. A common rule of thumb is to add 2 to 4 inches for a slight puddle, 6 to 8 inches for a moderate puddle, and 10 to 12 inches for a dramatic puddle.

With these measurements, you're ready to order or make your curtains. Don't forget to double-check your measurements before you start, as incorrect measurements can lead to curtains that are too small, too large, or the wrong shape. With a little care and attention, you can create beautiful, functional curtains that enhance your double windows and your entire room.
