179mm x 128mm postage royal mail

A specific question!

According to the Royal Mail's size and weight guidelines, a parcel with dimensions of 179mm x 128mm would fall into the following categories:

• Length: 179mm (which is within the maximum length of 240mm)
• Width: 128mm (which is within the maximum width of 380mm)
• Height: Not applicable, as this is a 2D item (not a 3D parcel)

As a result, this item would be classified as a "Large Letter" or "Large Parcel" by Royal Mail, depending on its weight.

Here are the Royal Mail's size and weight guidelines for Large Letters and Large Parcels:

• Large Letters: Up to 240mm long, 380mm wide, and 5mm thick. Weight limit: 100g.
• Large Parcels: Up to 610mm long, 460mm wide, and 305mm high. Weight limit: 2kg.

If your item weighs more than 100g, it would be classified as a Large Parcel and would require a parcel stamp. If it weighs 100g or less, it would be classified as a Large Letter and would require a large letter stamp.

Please note that these are general guidelines, and specific rules may apply depending on the type of item, its contents, and the destination. It's always a good idea to check with Royal Mail or a post office for the most up-to-date information and to ensure compliance with their regulations.
