How to Find Your Ring Size at Home

Since every ring at Swan Jewellry is handcrafted specifically for you, getting the right size matters before you choose from our rings. Here are three simple ways to find your ring size from home before you order.

Method 1: Measure an Existing Ring

Take a ring that already fits the intended finger well and measure the inside diameter in millimeters using a ruler. Compare that measurement against our ring size guide to find your closest US size. This is usually the most accurate at-home method.

Method 2: String or Paper Strip

Wrap a thin strip of paper or a piece of string snugly around the base of your finger, mark where it overlaps, and measure the length in millimeters. Compare that circumference to the ring size guide to find your size.

Method 3: Printable Ring Sizer

Many printable ring sizing guides are available online, print one at 100% scale (not "fit to page"), cut it out, and follow the instructions to find your size.

A Few Tips for Accuracy

Measure your finger at the end of the day when it's slightly larger, avoid measuring when your hands are cold, and if you're between two sizes, it's generally better to size up slightly for comfort.

Still Not Sure?

If you're ordering as a gift and can't ask the recipient directly, borrowing a ring they already wear on the intended finger and measuring it is usually your best bet. Our gifts for her and gifts for him pages list pieces by recipient. If you have any questions about sizing before you order, reach out, we're happy to help you get it right the first time.
