Can I send letters of any size?

Your letter or card can have any shape or size, but if it's not the standardised dimension then you will have to pay a surcharge.

A standardised letter or card is always rectangular with the following characteristics:

  • Minimum 90 x 140 mm
  • Maximum 125 x 235 mm
  • Maximum 50 g
  • Maximum 5 mm thick
