Understanding Ring Sizes
Ring sizes vary across different countries and systems. Here’s a quick overview:
- US/Canada: Sizes range from 3 to 13, including half sizes.
- UK/Australia: Sizes typically range from F to Z.
- EU: Sizes range from 41 to 76.
Our calculator provides conversions between these systems for your convenience.
Tips for Accurate Measurement
- Measure your finger at the end of the day when it’s at its largest.
- Avoid measuring when your hands are cold, as fingers tend to shrink.
- If your knuckle is significantly larger than your finger base, measure both and choose a size in between.
- For wide bands, go up a half size for comfort.
Factors Affecting Ring Size
Several factors can influence your ring size:
- Temperature: Fingers expand in warm weather and shrink in cold.
- Weight fluctuations: Significant weight changes can affect finger size.
- Pregnancy: Hormonal changes can cause fingers to swell.
- Age: Knuckles may enlarge over time, affecting ring fit.

Frequently Asked Questions
How accurate is an online ring size calculator?
While online calculators provide a good estimate, for the most accurate sizing, visit a local jeweler for professional measurement.
Can I measure my ring size at home?
Yes, you can use our calculator with a simple string or paper strip measurement. However, for important purchases like engagement rings, professional sizing is recommended.
How do I measure my partner’s ring size secretly?
Borrow a ring they currently wear on the intended finger and use our calculator. Alternatively, trace the inner circle of the ring on paper and measure the diameter.
What if I’m between sizes?
