Ring size guide

Ring size guide

Let's put an end to ring size confusion. Follow these two simple guides below, so you can start shopping the right sizes.

Method 1: Use a ruler to measure the inner diameter in mm of a ring that fits the intended finger.

Method 2: Wrap a thread around your finger, mark the overlap, and measure in mm to find the circumference.

Compare the result with the chart below. If you're in between sizes, we recommend sizing up for comfort.

Tips & Tricks:

  • We only offer full sizes. If you're in between, size up.
  • If your knuckles are wider than your finger base, measure those too.
  • Fingers swell during the day – measure in the evening at room temperature.
  • Buying as a gift? Borrow one of their rings and measure the inside diameter.
