A Series



Belonging to the ISO 216 series, A0 is a paper size that stands out due to its unique dimensions and widespread usage. The A0 size, measuring 841mm by 1189mm, is the largest in this series and serves as the defining metric for all other sizes within the range.

One intriguing aspect of A0 paper is its area of one square meter. This characteristic makes it an ideal choice for large-scale printing needs such as architectural plans or advertising posters. Its aspect ratio, which remains constant throughout the ISO series at approximately 1:√2, ensures that two pages of a smaller size can be combined to form one page of a larger size without any distortion or loss in content.
