Ring Sizing Guide

How to Determine
Your Ring Size

Method 1 — Using a ring you already own

Print this guide with page scaling set to 100%.
Place a ring you already own over the circles on the right.
Match the inside of the ring to the circle nearest in size. Measurements refer to the inside diameter of the ring.
If the ring falls between two sizes, order the larger size.

Please note

Consider band width. The wider the band, the tighter it may feel — you may need to go up by half a size.
This guide serves as a reference. For a more accurate fit, contact us for a complimentary sizing consultation.

Method 2 — String or paper

Wrap a thin strip of paper around your finger at the knuckle.
Mark where the paper overlaps and measure the length in mm.
Divide by 3.14 to get your diameter, then match to the chart.
Measure in the evening when fingers are at their largest.

✦ All Guesthouse pieces can be resized within the first year at no charge, within sizing tolerances for that particular piece. We're happy to help — reach out before you order.
