Ring Size Guide

Choosing a ring is a beautiful moment—finding the right size makes it even more special. To help you shop with confidence, we’ve put together a simple guide with practical ways to measure at home or with professional tools.

Things to Know Before Measuring

1. Band Width Matters

Narrow bands (1–2mm) often feel looser, while wider bands or ring guards feel snugger. If you’re choosing a wider style, consider going up by ¼–½ size.

2.Not Every Ring Can Be Resized

Eternity bands and intricate designs usually can’t be resized without affecting their structure. Choose carefully if you prefer these styles.

3.Comfort Over Perfection

Your fingers may swell slightly in the afternoon or in warmer weather. It’s best to measure at different times of day for a more accurate fit.

How to Measure Your Ring Size ？

1. Use a Ring That Fits You Well

Already have a perfectly fitting ring? Simply place a ruler across the top or bottom to measure the inner diameter and band width. Send us photos and your height/weight, and we’ll help you find the right size.

Measure your ring’s inner diameter and band width according to the image guide.

  • Inner Diameter

  • Band Width

2. Plastic Ring Sizer

Lightweight and easy to use — simply slide it onto your finger, ensuring it fits snugly yet allows for smooth rotation without gaps.

3. Ring Size Gauge

A metal ring gauge provides the most accurate measurement at home. It closely mimics the feel of an actual ring.

4. Visit a Jeweler

For the most reliable result, have your finger measured by a professional jeweler. Don’t forget to ask about the band width they use, since it can affect how the ring feels.

5. String or Paper Method

Wrap a strip of paper or string around your finger, mark where it overlaps, then measure the length. This method is less precise, so use it only as a general reference.
