Sizing Guide

Two at-home ring-measuring methods, plus bracelet sizing.

US sizing only for now — see the module doc for the open regional-conversion question.

At home

Find your ring size

Fingers change slightly with temperature and time of day — measure in the evening, when a finger is at its largest, for the most consistent result.

Using a ring you already own

1.Pick a ring that fits the intended finger and sits comfortably, not too loose or tight over the knuckle.
2.Measure the inside diameter in millimeters with a ruler, edge to edge across the widest point.
3.Match that measurement against the reference chart below.

Using string or a strip of paper

1.Wrap a piece of string or paper snugly around the base of the finger, then mark where it overlaps.
2.Measure the length from the start to the mark in millimeters — that is the circumference.
3.Match that measurement against the circumference column in the chart below.

Ordering from outside the US?

We currently size every piece to the US system shown above — we don't yet offer a UK or EU size conversion on the site itself. If you know your size in another system, contact the atelier before ordering and we'll confirm the equivalent US size with you directly.

At home

Find your bracelet size

Wrap a soft tape measure (or a string, then measure the string) around your wrist just below the wrist bone. Add 1–1.5cm of ease for a comfortable fit, or less for a snug one — the exact ease is a matter of preference, not a fixed rule.

Still not sure, or ordering a gift and don't want to guess? The atelier is glad to help you get it right before it's cast.
