Jewellery Sizing Guide: Choose the Right Ring Size & Chain Length. The right size decides whether a piece is worn or set aside. This guide covers it all: finding your ring size and choosing the right chain length.

Find your ring size

Ring size equals the inside circumference in millimetres. Measure the inside of a ring that fits (diameter × 3.14 = circumference) or use our ring size calculator.

Choose your chain length

Length decides where a chain sits. Classic is 40–45 cm; a long necklace reaches 60 cm and beyond.
