What you need to know
A0 is the base of the entire ISO 216 A-series paper system. It has an area of exactly 1 square meter (841×1189mm), and every other A-series size is derived by halving it: A1 is half of A0, A2 is a quarter, A3 is an eighth, and so on down to A10. This mathematical relationship makes the system elegant for scaling between sizes.
A0 is primarily used in professional settings: architectural and engineering drawings (blueprints), large-format scientific posters for conferences, retail window displays, and exhibition graphics. It requires wide-format printers — no standard office printer can handle this size.
At 300 DPI, an A0 image is nearly 10,000×14,000 pixels — a massive file. For most A0 applications (posters, plans viewed from arm's length), 150 DPI (4967×7022 pixels) is sufficient and produces a much more manageable file size. Only use 300 DPI for A0 if the print will be viewed up close.
