Cut a narrow strip of non-stretch paper (~1 cm wide, 10 cm long). Wrap it snugly around your ring finger โ it should feel like a comfortable ring, not tight. Mark the overlap with a fine pen while still on your finger, then measure from the edge to the mark in mm. Match to the Circumference column above.
Place an existing silver ring that fits on a flat ruler. Measure the inner diameter in mm (straight across the inside). Match to the Diameter column in the chart. This is the most accurate method if you already own a ring that fits the same finger perfectly.
Digital calipers (available from Bunnings or hardware stores for $10โ$20) give the most precise inner diameter measurement. Open the jaws, place inside your existing ring, and read the diameter in mm to 0.1 mm accuracy. Enter this into the calculator below for an instant AU size.
Any Australian jeweller will measure your finger for free using a professional ring sizer mandrel or plastic ring gauge set. Most major jewellers including Michael Hill, Shiels, and independent stores offer this as a complimentary walk-in service โ no appointment needed.
