A2 is a sweet spot for medium posters, art prints, and technical drawings. Use the rounded inch conversions and print guidance below to scale from A1 or A0, set bleed and safe zones, and keep artwork sharp.
Dimensions
- Millimeters: 420 mm × 594 mm
- Inches: 16.54 in × 23.39 in
- Area: about 0.25 m² (387.8 in²), half of A1
- Ratio: 1:sqrt(2), tiles cleanly with other A sizes
Print setup tips
Add 3 mm bleed, keep text at least 6 mm inside the trim, and export to PDF or 300 dpi images. Scaling A1 to 70.7 percent or A0 to 50 percent approximates A2 dimensions; ISO whole-mm dimensions and printer margins may require a final adjustment.
Common uses
Posters and signage
Medium posters for retail, events, or wayfinding that stay portable.
Art prints
Fine art or photo prints with room for borders and signatures.
Scaled technical sets
Step-down reductions from A1 or A0 for review sets while keeping proportions.
Print-resolution, bleed and margin examples are starting points, not ISO paper-size requirements. Follow the printer or publisher’s specifications; vector PDF content does not have a single image DPI.
