What size letterbox number should I choose?

We generally recommend a minimum of 75mm height for a letterbox number - anything smaller can be difficult to read from the street. The 50mm size suits situations where the number is viewed up close, such as apartment doors or letterbox banks.

A handy tip before ordering: print your numbers on paper at actual size, tape them to your letterbox, and check how easily you can read them from the street.

If your letterbox sits well back from the street, consider a larger number from our custom numbers and letters range instead.
