Understanding Postal

There are some other nuances to the new requirements. If you use polywrap or envelopes to mail your catalogs, look at the actual requirements.

Fonts and Spacing Rules
New requirements for delivery address font sizes and character/line spacing specify that unless the catalog is mailed at automation postage rates, a minimum font size of 8 point type (each character has to be at least 0.080 inches high) must be used for the delivery address. For catalogs mailed at automation rates, a minimum font size of 6 point type (each character must be at least 0.065 inches high) can be used, but the address must be printed in all capital letters.
