Ring Sizing Guide
Our Ring Sizing Guide is a helpful tool for finding your ring size at home. We also strongly recommend getting professionally sized before placing your order — either by booking a no-obligation consultation with us, or visiting a local jeweller if you're unable to visit our South-East London workshop.
We make everything to order, and each ring takes time and care to make by our small team, which is why it's especially important to know your ring size before ordering. If your ring is the wrong size, we will invite you to send your ring back to us for a resize, as we do not have extra sizes available for exchanges.
If you're unsure of the ring size you require, chat to us, and we can help.
Thank you for helping us minimise waste!
How to find your ring size
We find the best way to find your ring size at home is to measure the internal diameter of a ring you already own.
Simply place a ring that already fits on top of a ruler or measuring tape to find your size.
If you come up between two sizes, for example the diameter is 18.2mm, choose the half size, which in this example would be P 1/2.
| Internal Diameter (mm) | UK | US | EU |
| 14.5 | G | 3.75 | 45 |
| 14.8 | H | 4.25 | 46.5 |
| 15.2 | I | 4.5 | 47.5 |
| 15.6 | J | 5 | 48.5 |
| 16 | K | 5.5 | 50 |
| 16.4 | L | 6 | 51 |
| 16.8 | M | 6.5 | 52.5 |
| 17.2 | N | 6.75 | 53.5 |
| 17.4 | O | 7 | 55 |
| 18 | P | 7.5 | 56 |
| 18.4 | Q | 8 | 57.5 |
| 19 | R | 8.5 | 59 |
| 19.2 | S | 9 | 60.25 |
| 19.5 | T | 9.5 | 62.75 |
| 20 | U | 10 | 63 |
| 20.3 | V | 10.5 | 64 |
| 20.7 | W | 11 | 65 |
| 21.1 | X | 11.5 | 66.5 |
| 21.4 | Y | 12 | 67.5 |

Ring Sizing Tips
Measure by circumference
Wrap some string or paper around your finger, and mark where it overlaps to find estimated circumference.
Then, download our ring size conversion guide to find your ring size.
Are you hot or cold?
Your fingers can swell when you're warm, or shrink when you're cold.
Try to avoid measuring when you're too hot or feeling chilly - wait until you're at normal body temperature.
Consider ring thickness
Chunkier and wider ring styles may fit tighter than daintier designs.
If you're choosing a chunky ring, we recommend choosing half a size up from your normal size for comfort.
Need a different size?
Ring Re-sizing
To be as environmentally-friendly as possible, we make everything to order meaning we don't have spare rings to exchange, however we can resize your ring if you need a different size.
Please note, we may may charge a small fee to cover the time and materials it takes to resize your ring. If you need a resize, get in touch.
