How to Measure Your Ring Size at Home

Method 1 — Paper Strip (Most Accurate)

Cut a thin strip of paper

About 1 cm wide and 10 cm long. A piece of string or thread also works perfectly.

Wrap around your ring finger

Wrap snugly around the base of your left ring finger, ensuring it slides over the knuckle comfortably.

Mark the overlap point

Use a pen to mark exactly where the paper meets — this length is your finger circumference in mm.

Measure in millimetres

Lay flat on a ruler. Enter the measurement in mm into the calculator above to find your AU size.

Compare to the chart

If your result is around 47–48 mm, you are likely a size N — the average Australian women's size.

Method 2 — Measure an Existing Ring

Choose a ring that fits your ring finger well

Select one that slides on comfortably and doesn't spin loosely.

Measure the inner diameter

Use a ruler to measure straight across the inside of the ring opening in millimetres.

Match to the chart above

Find your diameter in the Diameter (mm) column — a measurement of 15.1 mm = AU size N.

Tips for Getting the Right Size

🌡️Measure in the afternoon: Fingers swell slightly during the day due to warmth and activity. Measuring in the afternoon gives the most accurate average size.
👈Left vs right hand: Your dominant hand is usually 0.5–1 size larger. If buying for the left ring finger, measure the left hand specifically.
📏Always size up if between sizes: If your measurement sits between two sizes — e.g. 47.2 mm — go up to size N (47.5 mm) for a comfortable fit.
💍Wide bands need a bigger size: If buying a ring with a band wider than 4–5 mm, order one size larger than your normal size for comfort.
❄️Avoid measuring in cold weather: Cold temperatures cause fingers to shrink. Always measure at room temperature or warmer for the most reliable result.
🎁Buying as a surprise gift? Australian size N is the safest guess for most adult women — it covers the most common size and is easy to resize slightly larger or smaller.

Frequently Asked Questions

What is the average women's ring size in Australia? ▼

The average women's ring size in Australia is size N, which corresponds to an inner circumference of 47.5 mm and a diameter of 15.1 mm. This is equivalent to EU size 47.5 and US size 6.5. The typical range for Australian women falls between sizes L and P.

What is size N in mm? ▼

Australian ring size N has an inner circumference of 47.5 mm and a diameter of 15.1 mm. If you measure your finger and get approximately 47–48 mm, size N is your correct Australian ring size.

What is the average women's ring size in US compared to AU? ▼

The average US women's ring size is 6–6.5, which converts directly to Australian size N. Australian sizing uses letters while the US uses numbers, but both systems agree that the average adult woman wears a ring with approximately 47–48 mm inner circumference.

Is Australian ring size the same as UK? ▼

Yes — Australian and UK ring sizes use exactly the same alphabetical system (A through Z+3). Size N in Australia is identical to size N in the United Kingdom. You can use UK ring size charts interchangeably with Australian charts.

What ring size should I buy as a surprise gift for a woman? ▼

If buying a ring as a surprise, Australian size N is the safest choice — it is the most common women's ring size. Most jewellers can also resize a ring up to 2 sizes in either direction, so a size N is a practical starting point if you are unsure.

Does weight or age affect ring size? ▼

Yes — both weight changes and age can affect ring size. Weight gain or loss of as little as 5–7 kg can shift ring size by 1–2 sizes. Fingers also tend to enlarge slightly with age due to joint changes. Always measure your current finger size rather than relying on an old measurement.

What is average ring size for a petite woman? ▼

Petite women with smaller hands typically wear sizes J to L (44–46 mm circumference). While size N is the overall average, women with a finer or smaller build may find sizes K or L a more comfortable fit. Always measure rather than guessing based on body type.
