Broome has a tropical climate with very hot, humid wet seasons (up to 40°C). Fingers can swell a full AU letter size in this heat. Always measure in air-conditioned comfort for an accurate result.
Fingers are naturally larger in the evening after a day of activity and fluid retention. Evening measurements give the most comfortable all-day fit for Broome's active outdoor lifestyle.
Your dominant hand's fingers are typically half an AU letter size larger. Most Australians wear engagement and wedding rings on the left hand — always size that specific hand and finger.
Hormonal changes and fluid retention during pregnancy can increase ring size by 1–2 AU letters. Size may return to normal after delivery — plan for a future resize rather than sizing up permanently.
Broome's beaches and water activities cause fingers to swell from sun exposure and salt water. Avoid measuring after a day at Cable Beach or a swim — measure indoors instead.
Wide bands and Broome pearl ring settings feel tighter than slim bands. Go up half an AU letter size when ordering a wide-band style or a pearl solitaire ring from a Broome boutique.
Cut a thin strip of paper about 1 cm wide and 10 cm long. Non-stretch thread or dental floss works just as well and conforms better to your finger shape.
Wrap snugly around the base of your left ring finger indoors in air conditioning. Make sure it also slides over your knuckle — the ring must pass over comfortably.
Mark where the strip overlaps with a pen. The length from the end to your mark is your finger circumference in mm.
Lay the strip against a ruler and read in mm. Enter the value into the calculator above to instantly find your AU letter size.
Find the closest circumference in the Australian Ring Size Chart above and read across for your full AU, US, UK, and EU size equivalents.
Pick a ring that fits comfortably on your left ring finger. Only use a ring worn on that exact finger — different fingers give different AU sizes.
Use a ruler to measure straight across the inside opening in millimetres. Measure at least twice and use the average for accuracy.
Find the matching diameter in the chart above and read across for your AU letter size, US, UK, and EU equivalents.
