business card envelope

Common sizes cover small mailing envelopes, standard business/long envelopes, and invitation sizes. Examples in listings include about 3.5 x 6.5 in (small), 4 x 9.5 in and roughly 4.13 x 9.5 in (standard business/long), and about 5.25 x 7.25 in (A7 invitation size).

Most envelopes are made from paper stock. Several listings note heavier, sturdier stocks — for example, some envelopes use about 120 gsm for a thicker or vintage-style feel.

Product details and reviewer comments indicate good printer compatibility for many listings: some envelopes run smoothly through home printers with minimal jamming and are described as compatible with both inkjet and laser printers. Check individual product notes for any printer-specific guidance.

A #10 or business-size envelope is shown at about 4.125–4.13 inches wide by approximately 9.5 inches long (listed as roughly 4-1/8 x 9-1/2 in).

A7 envelopes are about 5.25 x 7.25 inches and are commonly used for 5x7 photo prints, wedding invitations, bridal or greeting cards, and other similarly sized stationery.
