🧵 How to Measure Your Ring Size at Home
You can easily find your ring size using one of the following methods:
1. Measure an Existing Ring
- Use a ruler to measure the inside diameter of a ring that fits well.
- Match the measurement to the "Diameter" column in the chart above.
2. Use a String or Paper Strip
- Wrap a thin strip of paper or string around the base of your finger.
- Mark where the ends meet.
- Measure the length with a ruler (in mm) — this is your finger's circumference.
- Match it to the "Circumference" column in the chart.
⚠️ Measure your finger at the end of the day when it’s largest. Avoid measuring when your hands are cold.
📌 Additional Tips
- Rings with wider bands may require a slightly larger size.
- If buying for someone else, try measuring a ring they already wear on the correct finger.
- For bulk orders or custom sizing, contact our support team.
