Letter size and weight guidelines

We classify a letter as an item that:

  • weighs less than 500g
  • is no thicker than 20mm
  • contains flexible items**
  • has a rectangular shape
  • is no bigger than a B4 envelope (260mm x 360mm x 20mm)

If your item doesn't fit this criteria, we'd classify it as a parcel. View domestic parcel services.
