A Series



Belonging to the ISO 216 series, A7 is a distinctive paper size that holds its own unique place in the world of print and design. With dimensions measuring 74mm by 105mm, or approximately 2.9 inches by 4.1 inches, A7 strikes a balance between compactness and usability.

As part of the A series in the ISO standard, A7's area is exactly one-sixteenth of an A4 sheet - a fact that underscores its efficiency and practicality for specific applications. This size is particularly favored for pocket notebooks, small leaflets, and various other compact printed materials where space optimization is key.

A noteworthy aspect of the A7 paper size lies in its aspect ratio. Maintaining a consistent ratio of √2:1 across all 'A' sizes allows for seamless scaling without distortion - an attribute that designers greatly appreciate when working on projects requiring different scales.

In comparison to ANSI standards predominantly used in North America, there isn't a direct equivalent to A7. However, it closely aligns with the U.S.'s statement size (5.5" x 8.5") when folded twice.

Understanding these nuances about the A7 paper size can empower you to make informed decisions when planning your next print project or designing your next product line-up.
