Ring Size by Circumference
Wrap paper, string, floss, or a soft tape around the finger, mark the overlap, then measure the length in millimeters.
Do not pull too tight
The strip should sit comfortably around the finger and slide over the knuckle.
Measure at room temperature
Finger size can change with temperature, activity, and time of day.
This tool provides an estimated ring size only. Double-check before buying, especially for expensive, custom, or engagement rings.
FAQ
Common questions
How accurate is this ring size tool?
It provides an estimated ring size. Screen calibration, browser zoom, ring alignment, and measuring method can all affect the result.
Can I measure ring size on my phone?
Yes. A phone is often easier because you can place a ring directly on the screen after calibration.
What if I am between two sizes?
Check the fit with another method. Wider bands can feel tighter, so many buyers choose the larger nearby size for wide rings.
Should I use this for an engagement ring?
Use it as a starting point only. For expensive, custom, or engagement rings, confirm with a professional jeweler.
