Indonesian retailer sizes can vary
Indonesia does not have one independently verified national number-to-measurement scale. Current first-party guides from Indonesian jewelers use different number labels for some comparable measurements. Use this table only when buying from Frank & co.; for another retailer, confirm its own size guide or compare the inside diameter in millimeters.
Converting to US, UK, EU, Germany, or Japan sizes
This page shows Frank & co.'s retailer numbering only. To convert a diameter or circumference measurement (in mm, cm, or inches) into US/Canada, UK/Australia, EU, Germany, or Japan sizes using our core conversion data, use the ring size calculator instead.
Frequently asked questions
Is this Indonesia’s official national ring size scale?
No single universal Indonesian scale could be verified. This page mirrors Frank & co.’s own published guide (sizes 7–24, with millimeter diameter and circumference), which is authoritative for that retailer but not necessarily for every Indonesian jeweler.
How do Frank & co. sizes convert to US or UK sizes?
Use the diameter or circumference in millimeters from the table and convert with the ring size calculator, which maps millimeters into US/Canada, UK/Australia, EU, Germany, and Japan sizes. The retailer numbers themselves only have meaning inside Frank & co.’s guide.
Why show both millimeters and centimeters?
Because the source publishes both, and Indonesian shoppers commonly measure in either unit. The two columns describe the same physical sizes — centimeters are simply millimeters divided by ten.
I’m buying from a different Indonesian jeweler — can I use this chart?
Only as orientation. Ask that jeweler which scale their chart follows or what millimeter size they recommend; if they publish inside-diameter figures, convert those directly instead of translating through Frank & co. numbers.
