Most Bendigo jewellers stock a default size of AU size O as their standard off-the-shelf size for women's rings.

Thumbs are the widest finger. Thumb rings need to slide over the knuckle easily โ size slightly larger.
Slightly larger than the ring finger. Fashion rings worn on the index often need to go up half a size.
The largest of the three centre fingers โ usually the same size or half a size larger than the ring finger.
The most commonly measured finger. Default engagement and wedding ring finger. Average AU size is Nยฝ.
The smallest finger. Pinky rings are petite โ very small sizes may require ordering from a specialist jeweller.
Cut a strip of paper approximately 1 cm wide and 10 cm long. Non-stretch thread or dental floss also works perfectly.
Wrap the strip snugly around the base of the finger you want to size. Make sure it can still slide over your knuckle comfortably.
Use a pen to mark exactly where the paper overlaps itself. The length from the end to your mark is your finger circumference in mm.
Lay the strip flat against a ruler and measure the length in mm. Use this number to look up your AU size in the chart above.
Take 3 separate measurements and use the middle or average value for the most accurate and consistent result.
Choose a ring that already fits comfortably on the same finger and same hand you plan to wear the new ring on.
Use a ruler to measure straight across the inside opening of the ring in millimetres โ at the widest point.
Match your diameter measurement to the Diameter (mm) column in the chart above and read across for your AU letter size.
Bendigo's summer temperatures regularly exceed 35ยฐC. Heat causes fingers to swell โ size can increase by up to half a size in summer. Measure at normal room temperature.
In cooler Bendigo winters, fingers can shrink slightly. A ring sized in winter may feel loose in summer. Consider this when buying engagement rings.
Fingers are naturally larger in the evening due to daily activity and fluid retention. Always measure in the afternoon or evening for the most comfortable fit.
Your dominant hand's fingers are typically half a size larger than your non-dominant hand. Always measure the specific hand you'll wear the ring on.
Wide bands (6mm or more) feel tighter than narrow bands. If choosing a wide band โ including most men's wedding rings โ go up half a size from your measured size.
Most Bendigo jewellers can resize plain gold and silver bands by 1โ2 sizes. Intricate or stone-set rings may have resize limitations โ check with your jeweller first.
