How to measure for curtains

Don't order your curtains too narrow! You might think, "I'll measure for height by going from the mount spot to the floor. And I'll measure for width by measuring the window's horizontal opening." But if you do that, you'll be really disappointed.

There's nothing worse than having curtains that barely close in the middle. You want to have a lot of extra width on each side. Plus, the additional width helps the curtains look fuller when closed. They don't look stretched out and flat. I'm not an interior designer, but I'd order each side 50% wider than half the window's width.
