Ring Sizes

Size guide

Vintage rings were made long before sizes were standardised, so every piece is unique. Use this guide to find your size, then compare it with the size or inner diameter we list for each ring.

Find your size in three steps

01
Take a ring that fits

Ideally one you already wear on the same finger as your new ring.
02
Measure the inside

Lay the ring on a ruler and measure the inner diameter from edge to edge, in millimetres — without the band itself.
03
Look it up

Find the closest diameter in the chart below to see your EU, US and UK size.

No ring at hand? Wrap a thin strip of paper around the base of your finger, mark where it overlaps and measure its length. That is your circumference — compare it with the circumference column.

Good to know

Time of dayFingers are slightly larger at the end of the day and in warm weather — measure in the afternoon for the most reliable result.
In between sizesChoose the larger size, especially for wide bands and statement rings.
Vintage designsMany vintage designer rings are adjustable or worn across several fingers — we always mention this in the description.
