Frequently Asked Questions About Ring Size Chart
1. What is the most accurate way to measure ring size?
The most accurate method is to measure the inside diameter of a ring you already wear, in millimeters (mm), and then compare it with our Ring Size Chart. This chart converts your mm measurement into exact sizes for the US, UK, EU, Japan, Switzerland, Italy, and India. Measuring in mm avoids guesswork and ensures reliable international conversions.
2. Do Indian ring sizes match US ring sizes?
No, Indian ring sizes do not directly match US ring sizes. That’s why our Ring Size Chart for India is included. By checking your mm measurement against the chart, you can see the exact Indian size along with its equivalent in the US, UK, EU, and other systems. This makes it easy to buy rings internationally without worrying about mismatched sizes.
3. What if I’m between two sizes?
If your finger measurement falls between two sizes on the Ring Size Chart, it’s usually best to choose the slightly larger size. Fingers can swell with heat or activity, and a ring that is too tight can be uncomfortable. Our chart helps you see the closest international conversions, so even if you’re between sizes, you can select the most comfortable fit.
4. Why should I trust this Ring Size Chart?
Our Ring Size Chart is based on widely accepted international standards for US, UK, EU, Japan, Switzerland, Italy, and India.
