Poster Printing FAQs
What size poster should I print?
It depends on viewing distance. For posters viewed from 1-2 meters (office, classroom), A3 (297x420mm) works well. For 2-3 meters (event poster), A2 (420x594mm) is standard. For large spaces or conferences, use A1 (594x841mm) or A0 (841x1189mm).
What resolution do I need for a poster?
For posters viewed up close (under 1 meter), use 300 DPI. For standard poster viewing distances (1-3 meters), 150 DPI is sufficient. For large banners viewed from 5+ meters, even 72 DPI can look fine. Higher resolution is always better if your file size allows it.
