ISO 216 Standards: An Overview

The A, B, and C series established by the ISO 216 standard are commonly used to determine the size of a sheet of paper across the globe.

While this system is widely embraced in many parts of the world, it is not as familiar to those in North America and Latin America, where letter-size and legal-size sheets are the norm.

The A-series of paper sizes has eight sizes from A0 to A7. The sizes get smaller as you go from A0 to A7, which is indicated by the number that follows the letter getting lower.

The A-series provides a systematic approach to paper sizing, and a handy trick to remember when comparing different paper sizes in the series is that each subsequent number’s dimensions are half the size of the previous one.

For instance, an A1 sheet of paper with dimensions of 594 × 841 millimeters is exactly half the size of an A0 sheet, which measures 841 × 1189 millimeters.

The table below provides a visual representation of the relationship between each number in the A-series, giving a clearer idea of how each size relates to the others in terms of its dimensions.
