Every Rain and Rivers ring is made to measure. Glass is organic, and fingers grow and shrink by up to two sizes with heat and time of day, so each size covers a small range rather than a single number. Here is how to find yours.
Quickest way: use our online ring sizer. Place a ring you already own on your screen and it tells you your size.
How to measure at home
- Use a ring that already fits. Measure the inside diameter in millimetres, edge to edge, and find it in the chart below.
- Or measure your finger. Wrap a strip of paper around the base of your finger, mark where it overlaps and measure the length in millimetres. That number is your circumference; find the size whose range includes it.
- Measure at the end of the day, when fingers are slightly larger, and check that the ring will pass over your knuckle.
