At Class A Jewellers, all ring sizes are in Australian sizing. Australian sizing uses an alphabetical scale, where each letter corresponds to the ring's inner diameter and circumference.
FINDING YOUR RING SIZE
For an accurate ring size, professional measurement is essential.
Visit our Walkerville showroom and our attentive staff will ensure your finger is measured precisely, no appointment necessary.
MEASURING AT HOME
Start by finding a ring that comfortably fits your intended finger. Using a ruler or tape measure, measure the internal diameter (in millimetres) of the ring, as precisely as possible. Then, refer to our Conversion Chart below for the size recommendation.
COMPLIMENTARY RESIZING
We understand the difficulty of selecting the correct size for your significant other’s engagement ring, which is why we offer complimentary resizing. All Class A rings are entitled to one complimentary resize within the first 12 months of purchase.*
