Good to know

Print at 100% scale with “fit to page” disabled. Check the calibration reference on your printed page with a ruler. Place a ring you already wear over the circles; its inner edge should align with the outline. If you fall between sizes, we recommend the larger size. Ring width and setting style can affect fit.

02 / Measure at home

How to measure

A quiet moment and a strip of paper are all you need.

01

Wrap

Wrap a narrow strip of paper around the base of the finger. Keep it comfortably snug, not tight.

02

Mark

Mark where the paper meets, then lay it flat and measure the length in millimetres.

03

Compare

Compare your measurement with a trusted UK ring-size chart. Repeat once to confirm your result.

03 / Understand the stone

The considered fit

Your ring, perfectly sized.

A considered fit is part of the pleasure of wearing a ring. Use this guide as a starting point, then let our team help you find the size that feels entirely your own.

Measure with care

Wrap a narrow strip of paper around the base of the finger. Mark where the ends meet, then measure the length in millimetres for circumference.

Measure at the end of the day, when fingers are warm, and ensure the ring can pass comfortably over the knuckle. For the most precise fit, we recommend a professional sizing.
