Selecting the right ring size is a crucial step in ensuring that a piece of jewelry not only looks stunning but also fits comfortably on the wearer's finger. Whether you're planning a surprise proposal or treating yourself to a new ring, understanding how to measure your finger accurately is key. This guide will walk you through the steps to properly size a ring for a perfect fit.
Why Ring Size Matters:
Wearing a ring that fits well is not only aesthetically pleasing but also essential for comfort. A ring that is too tight can be uncomfortable, while one that is too loose may risk slipping off or spinning around the finger. Achieving the correct ring size ensures both the visual appeal and the wearer's ease.

International Ring Finger Sizes Diameter = Internal diameter in millimeters. Circumference = Internal circumference in millimeters.
Ring sizes below cover the standard wearable range (US 3 to US 13) using the AU/UK Wheatsheaf gauge — the same scale Natalia uses on her workshop mandrels. Use the circumference column as the source of truth — measure around your finger with a strip of paper and match the millimetres. Whole AU letters pair to whole US sizes (L = US 6, P = US 8, T = US 10, and so on); Natalia also makes some half-letter sizes on request.
