A Series Notebook Sizes Chart

The A Series paper size is known as the ‘International’ paper size to those within the United States. The A-series paper size can be confusing because we often think of the U.S. Legal Letter Size when we think of paper. However, if you look at the below chart, you will see that legal sized paper isn’t standard at all!

Interestingly, even in the U.S. one of the most common notebook sizes is the A5. You can find notebooks of this size in all stores across the world. Approximately ‘half-letter’ sized, it is the perfect size for easy carrying, While still allowing lots of room to write.

As you can see from the chart above, all A-Series paper sizes are derived by folding a single (but huge!) A0 sized paper in half multiple times (to a standard maximum of A10, that is 10 folds total!).

B Series Notebook Sizes Chart

B Series paper sizing was developed in order to provide common/standard paper sizes that were not available within the A Series’ framework.
