Ring Sizing Guide

Hand-forged vintage pieces often vary from modern standards. We provide measurements using inside diameter and circumference — if you're between sizes, we recommend going with the larger fit.

Measuring at Home

Avoid string or paper — both compress and give inaccurate readings. Use a professional ring sizer or a smartphone app, or measure a ring you already own and wear comfortably using a ruler across the inside diameter.

A few things worth knowing

Wide bands may require a half-size larger than your usual fit — the more surface area against the finger, the snugger the feel.

Measure at the end of the day, when fingers are at their largest. Temperature and time of day both make a difference.

Simple bands are usually straightforward to resize. Full eternity rings and pieces with enamel or continuous settings often are not — check individual product descriptions for guidance before purchasing.

When in doubt, size up — a ring that slides on easily is far better company than one that won't come off.
