AF Form 1913: Air Force Invitation Envelopes – If you’re a U.S. Air Force member, Department of the Air Force civilian, or involved in official military social events, AF Form 1913 refers to the standardized envelopes for invitations sized at 4 3/8″ x 5 3/4″. These envelopes support formal invitations, announcements, and social correspondence within Air Force protocol and etiquette guidelines.
This size matches the common A2 invitation envelope standard, widely used for greeting cards, RSVP cards, small invitations, folded notes, and photos in both military and civilian contexts.
What Is AF Form 1913?
AF Form 1913 is listed in official Department of the Air Force guidance as “Envelopes for Invitations”. It appears in DAFMAN 90-161, Publishing Processes and Procedures (18 October 2023, incorporating Change 1, 14 July 2025), under Chapter 10 on Printing Support, Procurement, and Social Protocol Stationery.
These envelopes are part of the Air Force’s approved social protocol stationery items. They ensure consistency in official and semi-official events such as:
- Change of command ceremonies
- Retirement parties
- Promotion celebrations
- Holiday greetings
- Unit social functions
The form number identifies the specific product in the Air Force’s printing and procurement system rather than a fillable document. Physical products like these are typically ordered through authorized channels rather than downloaded as a PDF.

Specifications of AF Form 1913 Envelopes
- Size: 4 3/8 inches x 5 3/4 inches (A2 envelope size)
- Purpose: Designed to hold invitation cards, note cards, RSVP cards, or small announcements without folding
- Typical Features (based on standard A2 envelopes used in similar government and commercial applications):
- Gummed or self-seal flap for secure closure
- Opaque paper stock (often 24 lb. or higher for a professional feel)

This dimension perfectly fits a quarter-folded 8.5″ x 11″ sheet or standard small invitation cards (approximately 4.25″ x 5.5″). It is smaller than A7 (5″ x 7″) or A9 (5 3/4″ x 8 3/4″) envelopes, making it ideal for compact, elegant invitations rather than full-size wedding-style cards.
