Ring size guide
Measure Ring Size With String
String is useful when you do not have an existing ring, but it needs careful handling to avoid stretching or tightening errors.
Wrap and mark
Wrap the string around the finger base, mark the overlap, then lay it flat against a ruler.
Repeat the measurement
Take two or three readings and use the average if they are close.
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.
