Question 2

Why do different countries use different ring sizes?

Accepted Answer

Different regions developed unique sizing systems based on their measurement traditions. The US uses a numeric scale, the UK uses letters, EU measures inner circumference in mm, and Japan has its own numeric system. These evolved independently before global commerce standardized other measurements.

Question 3

How can I find my ring size at home?

Accepted Answer

You can measure your ring size by wrapping a strip of paper around your finger, marking where it overlaps, then measuring the length in millimeters. This gives you the circumference, which you can convert to any sizing system using our tool.

Question 4

Do ring sizes vary between brands?

Accepted Answer

Most jewelers follow standard sizing charts, but there can be slight variations. For expensive purchases, it's best to get professionally sized or order a ring sizer. Our conversions use internationally recognized standards.

Question 5

What is the difference between inner diameter and circumference?

Accepted Answer

Inner diameter is the distance across the inside of the ring. Circumference (used by EU sizing) is the distance around the inside. To convert: Circumference = Diameter × π (3.14159). Our converter handles this automatically.
