China Ring Size Chart
China doesn't use US, UK, or EU numbering — it shares the same numeric sizing scale documented for Japan, South Korea, Hong Kong, and Singapore.
China shares the same scale as Japan
Both sources behind our Japan data independently name China as using the identical numeric scale.
We haven't found a China-specific ring sizing convention that differs from the East-Asia numeric scale already documented on our full ring size chart (labeled "Japan" there). Rather than duplicate that data under a new name, this page shows the exact same verified numbers, relabeled for anyone searching specifically for a China ring size chart.
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?
China doesn't use the US, UK, or EU numbering — it shares the same numeric scale documented for Japan in our full chart (sometimes called the "Asian" ring size system). Both of the independent sources behind our Japan column state this same scale is also used in China, South Korea, Hong Kong, and Singapore.
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 exact same verified values already in this site's Japan column (see /ring-size-chart), not a separate or newly invented dataset — we haven't found a China-specific numeric scale that differs from the shared East-Asia system described above.
