Create an a7 →Design tips
A7 paper is 74×105mm (2.91×4.13 inches). At 300 DPI, that's 874×1240 pixels. A7 is the size of most mini notebooks, small greeting cards, and pocket reference cards. An A7 envelope (C7) fits an A7 card perfectly, making it popular for invitation RSVP cards and thank-you notes.
- •A7 is roughly playing-card size. Use 8pt+ body text minimum — it's too small for fine print.
- •Don't confuse ISO A7 (74×105mm) with the US "A7 envelope" (5.25×7.25") — they're different.
- •A7 cards fit C7 envelopes (81×114mm). Great for RSVP cards, thank-you notes, and mini flyers.
What you need to know
A7 is half of A6 and roughly the size of a playing card. It's commonly used for mini greeting cards, RSVP cards, pocket notebooks, small flyers, and price tags. The A7 envelope (C7, 81×114mm) is a standard product at most stationery suppliers.
In the US, "A7" also refers to a popular envelope size (5.25×7.25 inches) which is completely different from ISO A7 paper. This naming collision causes frequent confusion. When someone says "A7 envelope" in the US, they almost certainly mean the American A7 envelope, not the ISO C7 envelope that fits ISO A7 paper.
At this small size, design simplicity is essential. Body text should be 8pt minimum, and layouts should have generous margins relative to the paper size. A7 is too small for detailed documents — think of it as a card format (invitation, thank-you, mini flyer) rather than a document format.
