Frequently Asked Questions About Envelopes
A #10 envelope measures 4-1/8" x 9-1/2" and is the standard choice for business letters, invoices and statements. A #9 envelope is slightly smaller at 3-7/8" x 8-7/8" and is commonly used as a return envelope inside a #10 mailing.
Catalog envelopes open on the short side, while booklet envelopes open on the long side. Both are good choices for mailing larger documents, reports and printed materials without folding.
Security envelopes have a printed interior that helps prevent contents from being seen through the paper. They're commonly used for checks, financial statements, invoices and other confidential business mail.

Gummed envelopes require moisture to seal. Self-seal envelopes typically use two adhesive strips that stick together when pressed. Peel-and-seal envelopes have an adhesive strip covered by a removable liner. For frequent mailing, peel-and-seal is a convenient option.
