Ring Sizing Guide
Finding the right ring size is easy! Follow the steps below to measure your finger at home and shop with confidence. Remember, our Arc ring is resizable — perfect if you're between sizes.
How to Measure Your Ring Size
Method 1: String or Paper Strip
- Cut a thin strip of paper or use a piece of string.
- Wrap it snugly around the base of the finger you want to wear the ring on.
- Mark where the paper or string overlaps.
- Measure the length in millimetres — this is your circumference.
- Use the chart below to find your size.
Method 2: Measure an Existing Ring
- Place a ring that fits you well on a flat surface.
- Measure the inner diameter in millimetres.
- Match the diameter to the chart below.
💡 Tips for an Accurate Measurement
- Measure at the end of the day — fingers are slightly larger in the evening.
- Measure when your hands are warm, not cold.
- If your knuckle is larger than the base of your finger, measure both and choose a size in between.
- Measure 2–3 times for accuracy.
