Envelopes 101

This happens all too often: a project is conceived, designed, and printed before any thought goes into how it will be mailed. When this happens, you may find yourself scrambling to find envelopes that fit your print piece properly.

Planning Ahead for Mailing

Before you finalize your print project, consider these key questions:

  • What size envelope will you need?
  • Will the piece need to be folded to fit?
  • Are there postal regulations that affect your design?
  • Will you need window envelopes for address visibility?

Standard Envelope Sizes

The most common business envelope is the #10, measuring 4-1/8" x 9-1/2". This size comfortably accommodates a standard letter-sized document folded in thirds. Other popular sizes include:

  • #9 Envelope: Slightly smaller, often used for reply envelopes
  • #6-3/4 Envelope: Perfect for statements and invoices
  • A7 Envelope: Ideal for 5x7 invitations and announcements
