Frequently asked questions

Is this the official Indonesian ("Nomor") sizing chart?

No — these figures are reproduced from a third-party source, not sourced or verified directly from the manufacturer or an official standards body. Always confirm with the manufacturer or retailer before purchasing.

Why isn't this data verified like the rest of your site?

Every other page here traces its sizing figures back to one dataset we maintain and test ourselves. This page instead mirrors numbers published by a third party, at face value, so you can compare it alongside our own verified US/UK/EU/Germany/Japan chart and calculator.
