A5 is A0 halved five times, just under half an A4. The sizes hub walks through the whole series.
What A5 is good for
A5 is half of A4: greetings-card territory, not wall territory. It’s too small to carry a room on its own, which is exactly why it works folded and handed to someone. If you want the same image on a wall as well, print it at A3 or larger and keep A5 for the card.
How the A series reaches A5
Fold an A4 sheet in half across its long side and you have A5: 148 × 210 mm. Every A size keeps the same 1:√2 shape, so artwork that fits A5 scales up to A4 or A3 without a new crop. The hub has the full series and the arithmetic.
Will your file carry A5?
The same division applies: pixels over dpi gives inches. A5 at 300 dpi wants 1748 × 2480 pixels, around 4.3 megapixels, which is a low bar by any modern standard. At 150 dpi it is 874 × 1240.
The catch at this size isn’t resolution but crop. An image that reads well on a wall often has space around the subject that simply disappears when the whole thing is the size of a postcard, and fine detail that was the point of the picture can end up too small to find. Choose an image that works close-cropped, or accept that the card is showing a fragment of the piece, not all of it. miniature photography guide is the place to start if the photograph itself is still to be taken.
A5 for cards, zines and reference sheets
A5 is the size of a folded greetings card, a paperback notebook and most small-press zines, which is why it turns up in so much hobby work. Painters print an A5 card of a finished figure to prop beside it at a show, roleplayers print character sheets and handouts at A5 so they sit on a crowded table, and illustrators test a print run at A5 before paying for anything bigger. At 300 dpi it needs a file of 1748 × 2480 pixels, which most phone photos clear easily.

Divide pixels by dpi and you have the size in inches. Three hundred dpi is a convention for things held close, not a rule; a print read from across a room is untroubled at 150. Every size above is worked from the ISO 216 definition: A0 is 841 × 1189 mm and each size halves the longer side, rounded down to whole millimetres.
