Are all greetings cards considered small royal mail

In the UK, Royal Mail has a specific classification system for mail items, including greetings cards. While most greetings cards are considered small items, not all of them are classified as "Small Royal Mail" (SRM).

Here's a breakdown of the Royal Mail size and weight categories:

  1. Small Royal Mail (SRM): These are items that weigh up to 100g and measure up to 24cm x 16.5cm x 0.5cm (9.4in x 6.5in x 0.2in). SRM items are typically charged at a flat rate, regardless of their size or weight.
  2. Large Letter: These are items that weigh up to 100g and measure between 24cm x 16.5cm x 0.5cm (9.4in x 6.5in x 0.2in) and 35.3cm x 25cm x 2.5cm (13.9in x 9.8in x 1in). Large Letters are charged based on their weight.
  3. Packet: These are items that weigh more than 100g or measure larger than the Large Letter size. Packets are charged based on their weight and size.

Most greetings cards, being small and lightweight, are typically classified as Small Royal Mail (SRM) items. However, if your card is larger or heavier than the SRM size and weight limits, it may be classified as a Large Letter or Packet, which would incur a higher postage cost.

To determine the correct postage for your greetings card, you can use Royal Mail's online postage calculator or consult with a post office staff member.
