Find My Ring Size
Getting your ring size right matters, especially for a piece that's crafted just for you. This guide gives you three reliable ways to find your size, plus our complete Australian size chart with international conversions.
Three Ways to Find Your Size
1. Measure a ring that already fits
The most accurate at-home method. Take a ring that fits the intended finger well, lay it on a ruler, and measure the inside diameter in millimetres (inner edge to inner edge, across the widest point). Match it against the chart below.
2. Measure your finger
Wrap a strip of paper or a piece of string snugly around the base of your finger, mark where it overlaps, then measure the length in millimetres against a ruler. That's your inside circumference. Find it in the chart below, and measure two or three times for consistency.
3. Let us help: choose "Select Later"
Not sure, or planning a surprise? Choose "Select Later / Help Me Choose" when ordering any ring. We'll personally confirm the size with you before your piece is crafted. No guesswork, no risk. Planning a proposal? Message us and we'll share our favourite tricks for finding her size discreetly.
Tips for an Accurate Fit
- Measure at the end of the day: fingers are smallest in the morning and in the cold. Aim for a normal body temperature.
- Measure the correct hand: your dominant hand usually runs slightly larger.
- Larger knuckles: measure both the base of your finger and your knuckle, and choose a size in between. The ring must pass over the knuckle but not spin freely.
- Between two sizes? Choose the larger one.
- Wide bands (4mm and up) fit more snugly, so consider going up a half size.
- Sanity check: the most common women's sizes fall between K and P. If your measurement lands well outside that range, re-measure with a second method before ordering.

Resizing Down the Track
Most solitaire and plain-band styles can be resized by a jeweller later. Eternity and pavé designs with stones all the way around have limited resizing options. That's one more reason to get the size right the first time, and why our "Select Later" option exists. For resizing details, see our Returns & Exchanges page or contact us before ordering.
