Ring Sizing

There are many ways to work out your ring size; here are a few options you can try:

Option 1: Measure a Ring You Already Own (AU Sizes)

Best for: If you already have a ring that fits the intended finger.

  1. Choose a ring that fits well
    Use a ring that fits the correct finger on the correct hand (remember, your dominant hand may be slightly larger).
  2. Measure the internal diameter
    Lay the ring flat and measure straight across the inside of the ring (not including the band) using a ruler or caliper. Note the measurement in millimetres (mm).

  3. Match it to an AU size chart
    Use the diameter to find your corresponding Australian ring size. Here’s a quick reference:

Internal Diameter (mm) AU Ring Size
15.7 mm J
16.1 mm K
16.5 mm L
16.9 mm M
17.3 mm N
17.7 mm O
18.1 mm P
18.5 mm Q
18.9 mm R
19.2 mm S
19.6 mm T
20.0 mm U
20.4 mm V

 

Option 2: Get Professionally Measured

Best for: 100% accuracy, especially for engagement or wedding rings.

Visit a local jeweler and ask them to measure your finger. It’s fast, free, and ensures peace of mind—especially if you’re planning something special.

 

Option 3: Use a Plastic Ring Sizer Tool

Best for: The most accurate home method.

  1. Order a reusable plastic ring sizer online or from our shop.

  2. Slip the tool onto your finger and adjust until it feels comfortably snug.

  3. Read the size indicated on the tool.
