How to Find Your Ring Size

Find Your Ring Size

There are a couple of simple ways to determine your ring size before ordering:

Option 1: Use a Ring Sizer

The easiest way is to order a plastic ring sizer online (Amazon has them for around $5). They work like a little belt that you tighten around your finger until it fits comfortably.

Option 2: The String (or Paper) Method

If you don’t have a sizer handy, you can measure at home with string, floss, or a thin strip of paper.

Prepare the String and Ruler
Get a piece of string, floss, or paper, plus a ruler with millimeter markings.

Wrap the String Around Your Finger
Wrap it around the base of the finger you’ll wear the ring on. Make sure it feels snug but not tight — the ring should be able to slide over your knuckle comfortably.

Mark the Overlap
Use a pen to mark the point where the string overlaps into a complete circle.

Measure the Length
Lay the string flat against your ruler and measure the marked length in millimeters.

✅ Pro Tips

Measure at the end of the day when your fingers are slightly larger.

Avoid measuring when your hands are cold — fingers shrink in cooler temps.

If you’re between two sizes, it’s usually better to go slightly larger.
