Find Your
Rod Size
Three ways to measure your curtain rod in under a minute — no ruler, no measuring tape, no guessing.
The Penny Test
Grab a US penny and hold it flat against the side of your curtain rod. Compare widths.
Your rod is noticeably thinner than a penny. The penny overhangs on both sides.
Shop 1/2" Clips →Your rod is the same width as a penny. They line up flush on both edges — perfect match.
Your rod is wider than a penny. It's close in size to a quarter — both edges of your rod extend past the penny.
Shop 1" Clips →SilkSlide clips fit 1/2", 3/4", and 1" rods only. If your rod is smaller than 1/2" or larger than 1", SilkSlide is not compatible.
String Circumference
Calculator
Wrap a piece of string around your rod, measure the loop, and enter it below. Works with dental floss, a shoelace, or a strip of paper.
Dental floss, thread, or a thin strip of paper all work perfectly.
Pinch the spot where it completes one full loop around the rod.
Then enter that measurement below.
