RING SIZING GUIDE

How to Find Your Ring Size

The most accurate way is a quick in-person sizing. Here's how to get it right, plus what to do if you need a resize.

The most accurate ways to size

Visit a local jeweler

Any jeweler can size you on a ring stick, usually for free.

Measure a borrowed ring

Use a ring they wear on the left ring finger and have it measured on a ring stick at a jeweler.

Sizing tips

Snug, not tight

It should slide over your knuckle with a little resistance.

Measure at the end of the day

Fingers are slightly larger when warm and later in the day.

Mind your knuckle

If your knuckle is larger than the base of your finger, size for the knuckle.

Measure more than once

Size 2 to 3 times on different days to confirm.

Planning a surprise?

Our Ready to Ship rings come in size 6, the most common women's size, and your first resize is free. We can also resize after the proposal.
