Ring Size Guide
Not sure about your ring size? All ring sizes on our site are US sizes. You can measure easily at home with one of the two methods below and compare with the table.
Method 1: Use a ring you already own
Take a ring that fits the finger you want, place it on a ruler and measure the inner diameter in millimetres (inside edge to inside edge). Find the number in the diameter column of the table.
Method 2: String or a strip of paper
Wrap a string or a thin strip of paper around the base of your finger, snug but not tight. Mark where it meets, measure the length in millimetres – this is the circumference – and find the closest number in the circumference column.

Tips for an accurate measurement
- Measure at the end of the day, when your fingers are at their largest.
- Avoid measuring when your hands are very cold.
- If you are between two sizes, choose the larger one.
- For wide bands (over 6 mm), go up half a size.
- Make sure the ring can pass over your knuckle without too much effort.
