Frequently Asked Questions (FAQ)

How do I find my ring size?

Measure your finger circumference in millimeters and enter it. The chart converts it to US, UK and international ring sizes.

How should I measure my finger?

Wrap a flexible tape or strip of paper around the base of your finger, snug but not tight. Measure at the end of the day when fingers are largest.

Does finger size change?

Yes. Fingers swell in heat and shrink in cold, and size can vary between your dominant and non-dominant hand. Measure the exact finger the ring is for.

What if I am between sizes?

Size up. A slightly loose ring is more comfortable than one that pinches, and jewelers can resize most rings.

Is the ring size chart free?

Yes. It is free to use with no signup and no limits.
