Area and aspect ratio
A5 has an area of 0.03125 square meters, exactly one thirty-second of a square meter and half the area of A4. It shares the same 1:√2 aspect ratio as every other size in the A-series, so two A5 sheets side by side match one A4 sheet, and folding an A5 sheet in half produces two A6 sheets.
The ISO 216 A-series system
| Size | Millimeters | Inches |
|---|---|---|
| A4 | 210 x 297 | 8.27 x 11.69 |
| A5 | 148 x 210 | 5.83 x 8.27 |
| A6 | 105 x 148 | 4.13 x 5.83 |
| A7 | 74 x 105 | 2.91 x 4.13 |
A5 sits directly in the middle of the commonly used A-sizes. It is small enough to carry easily but large enough to write full sentences and paragraphs without feeling cramped, which is part of why it is a popular notebook size.
A5 vs half-Letter (5.5 x 8.5 inches)
| Size | Width (in) | Height (in) | Width (mm) | Height (mm) |

| Half Letter | 5.5 | 8.5 | 140 | 216 |
Half Letter, sometimes called Statement size, is the closest US equivalent to A5. A5 is slightly wider but shorter than Half Letter. Notebooks and planners sold as “A5 size” in the US market are usually true to the 148 x 210 mm measurement rather than Half Letter, since A5 has become a recognized standard size for stationery even in Letter-using countries.
Common uses
A5 is the standard size for many notebooks, journals, and diaries, since it fits comfortably in a bag or large pocket while still offering enough writing space. It is also used for flyers, event programs, recipe cards, small booklets, and some paperback books. Greeting cards are often sized as A5 folded in half, which produces an A6-sized card that fits a C6 envelope.
Practical tips for working with A5
If you are designing a flyer or booklet, remember that two A5 pages fit on one A4 sheet, so a print shop can often print A5 materials more cheaply by laying out two per A4 page and cutting them down. When buying an A5 notebook or planner, check the exact millimeter dimensions if precision matters, since some brands market close-but-not-exact sizes as “A5” for stationery lines.
