Find your ring size in Bundaberg, Queensland โ full AU/UK letter chart with US, EU conversions, inside diameter, circumference in mm, and a free size calculator
Bundaberg uses the standard Australian ring sizing system โ the same letter system used across all of Queensland and Australia. The most common women's ring size is AU/UK size MโN (US 6.25โ6.75, EU 52.5โ54, diameter 16.7โ17.1 mm). For men the most common size is AU/UK size RโT (US 8.75โ9.75, EU 59โ61.5). If buying a surprise gift, start with AU size N for women and AU size S for men โ both can be resized at any Bundaberg jeweller.
Thumbs are the widest finger. Thumb rings must pass over the knuckle for a comfortable fit.
Slightly larger than the ring finger. Usually requires going up half a letter size for comfort.
The largest of the three centre fingers. Typically similar in size to the index finger.
The primary sizing finger. Average AU N (US 6.75). Most engagement and wedding rings are worn here.
The smallest finger. Pinky rings are petite and may require specialist sizing for very small AU sizes.
Highlighted rows represent the most commonly purchased ring sizes in Queensland. AU ring sizes use the same letter system as UK sizes โ a UK N is identical to an AU N with no conversion needed.

Bundaberg's warm subtropical climate means fingers can swell noticeably in summer. A ring measured in January heat may feel uncomfortably tight on cooler winter days.
High humidity typical of Queensland summers can cause temporary finger swelling. Avoid sizing immediately after outdoor activity or time spent in water or sun.
Fingers are at their largest in the evening. Measure at the end of the day for the most accurate all-day comfortable fit โ not first thing in the morning.
Your dominant hand's fingers are typically half a letter size larger. Always measure the exact finger on the exact hand the ring will be worn on for accuracy.
Wide wedding bands over 6mm feel significantly tighter than narrow rings. If ordering a wide band, go up half an AU letter size from your normal measured size.
Ring size changes with significant weight gain or loss, pregnancy, and ageing. Re-measure if more than 2 years have passed since your last professional sizing.
Cut a thin strip about 1 cm wide and 10 cm long. A length of non-stretch thread or dental floss also works perfectly well.
Wrap snugly around the base of the finger you will wear the ring on. Ensure the strip can still slide past your knuckle โ if not, measure at the knuckle and round up half a size.
Mark the overlap point with a pen. The length from the end of the strip to that mark is your finger circumference in mm.
Lay the marked strip flat against a mm ruler. Note the measurement and enter it into the calculator above for your instant AU ring size result.
Find your circumference in the full AU size chart above and read across for the matching US, EU, and Japan equivalent sizes.
Pick a ring that fits comfortably on the same finger and same hand the new ring will be worn on. Do not use a ring from the other hand.
Use a mm ruler to measure straight across the inside of the ring opening in millimetres. This gives you the inner diameter.
Find the matching diameter in the full AU size chart above and read across for your AU/UK letter, US size, and EU size equivalent.
Most incorrectly sized rings in Bundaberg result from one of these avoidable mistakes. Each one can cause your ring to be the wrong size โ even when you believe you've measured correctly.
Fingers are at their narrowest after a night's sleep. Morning measurements often produce a size that is too small, resulting in a ring that feels tight by evening.
Bundaberg's summer heat can swell fingers temporarily. Measuring during the hottest part of the day may produce a size that is too large for comfortable all-day wear.
The dominant hand's fingers are typically half a size larger. Always measure the hand and finger the ring will actually be worn on โ not a different hand as a shortcut.
Some UK jewellers list half-letter sizes (Nยฝ). AU sizes are whole letters only. Confirm whether your retailer uses half sizes when ordering from UK-based online stores.
Elastic or cloth tape measures give inaccurate readings as they compress the finger unevenly. Always use a non-stretch paper strip and a rigid millimetre ruler for reliable results.
US, EU, Japanese and Indian sizes use entirely different scales from AU letters. Always confirm which sizing system a retailer uses before ordering any ring online from overseas.
