Average mail neck width

The average mail neck width can vary depending on the specific type of mail and the region. However, here are some general guidelines:

• For standard letter-sized mail (8.5 x 11 inches), the average neck width is around 1.5 to 2 inches (3.8 to 5.1 cm).
• For larger envelopes or packages, the neck width can be wider, typically ranging from 2 to 3 inches (5.1 to 7.6 cm).
• For smaller envelopes or packages, the neck width can be narrower, typically ranging from 1 to 1.5 inches (2.5 to 3.8 cm).

It's worth noting that the neck width is an important consideration when designing and printing mailpieces, as it affects the overall appearance and functionality of the mailpiece. A well-designed neck width can help ensure that the mailpiece is easy to open and close, and that the contents are protected during transit.
