Design Tips
- →Design at 300 DPI (7016 × 9933 px) for commercial print output — at A1 scale, 150 DPI shows grain on photographic content viewed close-up.
- →Headline type should be at least 60 pt to read from 5 metres. Body copy below 24 pt becomes unreadable at typical poster viewing distance.
- →For outdoor use, specify weatherproof lamination (gloss or matt) in the print brief — standard paper-based A1 warps in humidity.
- →Keep critical content within 20 mm of the trim edge as a safe zone; use 5 mm bleed for all edge-to-edge artwork.

What is A1 paper size in inches?+
A1 is 23.39 × 33.11 inches. This makes it comparable to the US 24×36 inch large-format poster (the US equivalent for outdoor and lobby signage). A1 is 0.61 inches narrower and 0.89 inches shorter than the US 24×36.
Is A1 a standard poster size?+
Yes. A1 (594 × 841 mm) is the international standard for large indoor event posters, window displays, and lobby graphics. In the US, the closest equivalent is the 24×36 inch poster. Both are suited for viewing from 3–5 metres.
How many A4 sheets fit in A1?+
Eight. A1 is 594 × 841 mm; folding it in half gives A2, again gives A3, and again gives A4. Each halving doubles the count, so one A1 sheet equals 2 × A2, 4 × A3, or 8 × A4 sheets by area.
