Envelope Sizes

About envelope size names...

Some envelope sizes have a name, such as the #10 (read "number ten") envelope. Sometimes the name matches the exact length of the envelope but other times it's just a close approximation used in the industry for quick reference.

If you're not familiar with the size names then be sure to double-check the measurements listed next to the name to ensure you're buying the size you need.
