Belonging to the ISO 216 standard, DIN A6 is a paper size that holds its own unique significance. This format, measuring 105 x 148 millimeters or 4.13 x 5.83 inches, is precisely half the size of its predecessor in the series, DIN A5.

As part of the A-series in ISO 216, DIN A6 shares a distinctive characteristic with other members of this family: an aspect ratio of √2:1. This intriguing mathematical property ensures that when you cut a sheet from this series parallel to its shorter side into two equal pieces, each piece retains the original aspect ratio.

DIN A6's compact dimensions make it an ideal choice for various applications where space efficiency and portability are paramount. From postcards and flyers to pocket notebooks and personal organizers - this versatile paper size has carved out a niche for itself in both professional and personal settings.

While not directly equivalent to any ANSI standard sizes used predominantly in North America, DIN A6 closely approximates the U.S. 'quarter letter' size (4.25" x 5.5").

DIN A6 stands as a testament to thoughtful design principles that prioritize functionality and adaptability while adhering strictly to international standards.
