US Envelope Series



Belonging to the ISO 216 standard, A-8 paper size is a unique and often overlooked member of the A-series. This series, recognized globally except in North America where the ANSI series is prevalent, follows an aspect ratio of √2:1. The dimensions of an A-8 sheet are 52 x 74 millimeters or approximately 2.05 x 2.91 inches.

What sets the A-series apart is its logical and user-friendly system based on folding sheets in half. An A0 sheet has an area of one square meter, and each subsequent number in the series represents a halving of the preceding sheet along its larger dimension. Thus, an A-8 sheet is precisely half the size of an A-7 sheet and a quarter of an A-6.
