China Ring Size Chart

A shared East-Asia size reference for comparing China labels with US, UK, and EU measurements. Confirm your retailer's guide before ordering.

A shared East-Asia reference, not a retailer guarantee

The sources behind our Japan data also name China, but no extractable China-specific retailer table was available in this audit.

Our sources describe China alongside the East-Asia numeric scale documented on our full ring size chart (labeled "Japan" there). This page presents the same moderate-confidence values for China searches, but it is not evidence that every China retailer uses one identical table.

We treat this scale as moderate confidence: our two corroborating sources agree closely at small/mid sizes but drift by 1-2 sizes at the largest sizes in this range. Treat results as a close estimate and confirm with your specific retailer before ordering.

Frequently asked questions

Does China have its own ring sizing system?

Our sources describe China alongside the numeric scale documented for Japan in our full chart. They also name South Korea, Hong Kong, and Singapore. Treat it as a shared East-Asia reference, not a guarantee that every retailer follows one identical table.

How accurate is the China size column?

We treat this as moderate confidence, the same rating we give the Japan column it's derived from — the two sources we cross-checked agree closely at small/mid sizes but drift by 1-2 sizes at the largest sizes. Treat it as a close estimate, and confirm with the specific retailer before ordering.

Where do these numbers come from?

They're the same documented values already in this site's Japan column (see /ring-size-chart), not a separate or newly invented dataset. We did not find an extractable China-specific retailer chart to independently confirm every label in this audit.
