A7 notebooks are super tiny, coming in at roughly 3 x 4 inches (74 x 105 mm) and are the size of 1/8 of an A4 sheet of paper (or half of an A6 notebook).
What do all these letters and numbers mean? Notebook sizes typically fall into two global systems: the ISO 216 A-series (A4, A5, A6, A10, etc) and the Japanese JIS B-series (B6, B7, B4, etc). There are some outliers such as traveler's size, passport, and pocket. Plus some makers simply create their own size based on their country's standard or available materials/printing process.
We have categorized our journals and notebooks into standard sizes, when possible, but it is important to know that there are slight differences in "standard" sizing, based on materials, style, and the country where the item is produced. Individual product descriptions will have specific details about size.
