Ring Size Guide

Finding your perfect ring size is the first step to wearing your Somya London piece with confidence. Use our guide below to measure accurately at home.

How to Find Your Ring Size

There are three easy methods to measure your ring size at home:

Method 1: Measure an Existing Ring

Place a ring that fits you well on a flat surface and measure the inside diameter (the distance across the inside of the ring) in millimetres. Match this measurement to the size chart above. If your measurement falls between two sizes, we recommend ordering the larger size for comfort.

Method 2: Use a Strip of Paper

1. Cut a thin strip of paper approximately 1cm wide.
2. Wrap it snugly around the base of the finger you wish to wear the ring on.
3. Mark where the paper overlaps with a pen.
4. Measure the length in millimetres, this is your finger circumference.
5. Match to the size chart above.

Method 3: Order a Free Ring Sizer

Not sure about your size? We offer a free ring sizer so you can measure with confidence before ordering. Simply add it to your cart and we'll post it to you.

Tips for the Best Fit

• Fingers can swell in heat and shrink in cold — measure at room temperature for the most accurate result.
• Measure at the end of the day when fingers are at their largest.
• If you have larger knuckles, measure both the knuckle and the base of your finger and choose a size in between.
• When in doubt, size up — it's easier to resize a ring that's slightly too large.

UK vs International Ring Sizes

Our rings are sized using the UK alphabetical system. Use the chart above to convert to US, EU, or diameter measurements if needed.
