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.
