Measuring at Home
String Method
Wrap a thin string around the widest part of your finger. Mark where the string overlaps and measure this length in millimetres. Compare the measurement to the size table below. For best results, measure in the evening when fingers are at their largest.
Paper Strip Method
Cut a 5mm strip of paper and wrap it around the base of your finger. Mark where the edge meets the beginning and measure this length in millimetres. Find your corresponding ring size in the international size table below.
Existing Ring Method
Measure the internal diameter of a well-fitting ring using a ruler or callipers. Record this measurement in millimetres and find your size in the table below. This method works well if you already have a comfortable ring.
Professional Sizing
Visit a jeweller for the most accurate measurement. Their specialised tools provide precise sizing, particularly important for engagement rings and wider bands.
Sizing Tips
- Measure in the evening when fingers are naturally larger. Daytime measurements may result in a ring that feels tight later.
- Ensure your hands are warm. Cold fingers temporarily shrink, leading to inaccurate sizing.
- Consider seasonal changes. Fingers are typically larger in summer and smaller in winter.
- Take multiple measurements on different days for consistency. One measurement may not be reliable.
- Wider bands (over 3mm) often require a half size larger than narrow bands for comfort.
- If you have prominent knuckles, choose a size that balances daily comfort with ease of removal.
- Your dominant hand is typically larger. Note which finger on which hand you're measuring.
