Share
Ring sizing is the most common anxiety about buying rings online. What if it doesn't fit? The good news: there are reliable methods for measuring at home, and the full size conversion table below covers every system you might encounter.
And if the thought of measuring is still daunting some of Clarabelle rings are adjustable. No measurement needed.
Method 1 — Measure a Ring You Already Own
This is the most accurate method if you already have a ring that fits the finger you want to wear a new ring on.
Place the ring flat on a piece of paper. Use a ruler to measure the inner diameter of the ring the distance across the inside of the ring — in millimetres. Use the conversion table below to find your size.
Method 2 — Measure Your Finger
Wrap a thin strip of paper or string around the base of the finger you want to size. Mark where the paper or string meets, then measure the length in millimetres. This is your finger circumference. Use the table below to find your size.
Tip: measure in the evening when fingers are slightly larger fingers swell slightly during the day and in warm weather. A ring sized on a cold morning may feel tight by evening.
Method 3 — Adjustable Rings
Some of Clarabelle rings are adjustable, fitting approximately sizes 5–8 US (49–57 EU). The ring shapes gently to your finger without tools or effort. If you are between sizes or simply do not want to measure, this is the easiest solution.
