What is the size limit for sending a registered mail?

Hongkong Post has specific size and weight limits for sending registered mail. The maximum weight for registered mail is usually capped at 2 kilograms for local items. For international registered mail, the weight limit can vary based on the destination country, so it is wise to check the details for specific destinations on the Hongkong Post website, as these can change. Regarding size, the dimensions of registered mail must typically not exceed 60 centimeters in length, and the combined length and girth should not exceed 90 centimeters. Additionally, there are requirements for the mailpiece to be adequately packed to prevent damage during transit. For the most current and specific information, including any potential updates to these limits or regulations, it is advisable to refer to the official Hongkong Post website.
