Smithton sits in northwest Tasmania with a cool, temperate and often rainy climate. Cold weather can cause fingers to contract slightly โ always measure indoors at a comfortable room temperature for accuracy.
Tasmanian winters can bring cold temperatures that temporarily shrink fingers. Never measure immediately after coming in from the cold โ allow 10โ15 minutes for your fingers to return to their normal indoor temperature.
Fingers are naturally at their largest in the early evening after a full day of activity. Measuring at this time gives the most comfortable all-day fit for any ring worn daily.
The dominant hand's fingers are typically about half an AU letter size larger due to greater muscle use and blood flow. Always measure the specific hand and finger the ring will be worn on.
A change in body weight of 5โ10 kg can shift ring size by 1 full AU letter in either direction. Re-measure if there has been a significant recent change in weight before ordering a new ring.
Wide bands over 6 mm sit higher on the finger and feel considerably tighter than narrow bands of the same size. When ordering a wide wedding band, go up half an AU letter from your normal measured ring size.
Cut a strip about 1 cm wide and 10 cm long. Non-stretch string, dental floss, or a thin fabric strip all work equally well as a substitute.
Wrap snugly around the base of the finger on the hand you'll wear the ring on. Ensure the strip still passes comfortably over your knuckle before marking.
Use a pen to mark exactly where the strip meets itself. The length from the cut end to this mark is your finger's inner circumference in mm.
Lay the strip flat against a ruler and read the length in mm. Enter this into the AU ring size calculator above to instantly find your AU letter size.
Locate the closest value in the Circumference (mm) column of the chart above and read across to confirm your AU letter, US number, and EU size.
Pick a ring that currently fits comfortably on the exact finger you are sizing โ it should feel snug but slide off without difficulty.
Use a ruler or digital calipers to measure straight across the inside opening of the ring in millimetres. Calipers give the most precise reading.
Locate the matching diameter in the chart above and read across to find your AU letter, US number, and EU size equivalents all at once.
