A5 is 148 × 210 mm — half an A4, and the standard for flyers, handouts and booklet pages. Here it is in pixels at every common DPI.
A5 paper is 148 × 210 mm (5.83 × 8.27 in). Because it is small and usually read in the hand, the DPI you choose matters more here than it does on a wall poster. These are the pixel dimensions at each common resolution:
| DPI | Pixels (px) |
|---|---|
| 72 | 420 × 595 px |
| 96 | 559 × 794 px |
| 150 | 874 × 1240 px |
| 300 | 1748 × 2480 px |
| 600 | 3496 × 4961 px |
For comparison at 300 DPI: A4 (210 × 297 mm) is 2480 × 3508 px, A6 (105 × 148 mm) is 1240 × 1748 px, and a standard postcard (100 × 148 mm) is 1181 × 1748 px.

Select A5 from the paper size preset, then set your DPI. The mm, cm, inch and pixel fields are linked, so the pixel size updates the moment you change resolution. Where that DPI figure comes from, and why a file tagged 72 is not automatically a problem, is covered in our guide to 300 DPI.
Landscape A5 is 210 × 148 mm, the shape you get from folding an A4 in half the short way — useful for menus, invitations and tent cards.
Small formats are unforgiving about trimming. Enter bleed and safe margin in mm to see the trim size, the size with bleed and the safe area at once, so nothing important sits near the cut.
Swap the preset to A6 or the postcard size to see how much smaller they run, which helps when you are deciding between a flyer and a mailer. A6 is another halving of A5; a postcard is 100 × 148 mm and does not belong to the A series at all.
A5 is small, held close, and almost always produced in multiples — folded, imposed or stitched. That combination makes it the one paper size where a slightly wrong pixel figure shows up on the finished piece.
Design at 1748 × 2480 px for 300 DPI. Add the standard 3 mm bleed and the sheet becomes 154 × 216 mm — 1819 × 2551 px, or 71 px more on each axis. The thing to notice is proportion: 6 mm of total bleed is about 4 % of an A5 width against 2.8 % of an A4, so the same trimming tolerance eats a bigger share of a small sheet. Hold type 5 mm (59 px) clear of the trim line, and use the mm to px converter for any bleed value your printer quotes differently.
Here is the trap. Folding a 210 × 297 mm A4 sheet across its long side gives two pages of 148.5 × 210 mm, but ISO 216 rounds the A5 short edge down to a whole 148 mm. At 300 DPI that half-millimetre is 1754 px against A5’s 1748 px — six pixels of drift that only appear when you build the page from a folded A4 rather than the A5 preset. Saddle-stitching adds a second rule: each A4 sheet carries four A5 pages, so the page count has to be a multiple of four. Our A4 page has the parent sheet’s figures.
Two A5 pages side by side make 296 × 210 mm, which is 3496 × 2480 px at 300 DPI. Set the canvas up as one spread whenever an image or a rule runs over the gutter, and add bleed on the three outside edges only — the fold is not a cut. On a thicker saddle-stitched booklet, the inner pages push out and get trimmed a little more than the outer ones, so keep anything critical at least 5 mm from the fore-edge. To check how large an existing image will land on that spread, the px to mm converter converts the other way.
A full-bleed A5 needs at least 1819 × 2551 px at 300 DPI, bleed included. A 12-megapixel phone photo at 4000 × 3000 px clears that comfortably; a 1200 px wide web image stretched across 148 mm lands at roughly 206 DPI and looks visibly soft in the hand, which it would not on a wall poster at the same figure. Resampling upward adds pixels without adding detail, and a DPI tag on its own changes nothing about the sheet — the DPI changer explains exactly what that tag does and does not do.
Reading distance is what decides this, and A5 is read at about 30 cm. That is close enough for the eye to resolve individual pixel edges on type, so the usable range starts higher here than it does on a poster.
| DPI | A5 in pixels | Sensible for | The catch |
|---|---|---|---|
| 72 | 420 × 595 px | Point-based files and the page box a PDF reports for A5. | A unit of measurement rather than a resolution. Printed, an A5 at this setting shows stepped edges on every letterform. |
| 96 | 559 × 794 px | Email attachments, social previews and web versions of a printed flyer. | Fine on a screen. On a small sheet held at arm’s length there is nowhere for the softness to hide. |
| 150 | 874 × 1240 px | Office-laser proofs and internal mock-ups you will not hand out. | A quarter of the pixels of the print file. Acceptable on a poster viewed from a distance, visibly rough on a hand-held A5. |
| 300 | 1748 × 2480 px | Flyers, invitations, booklet pages, menus — anything read in the hand. | The size to design at, and comfortably light at about 4.3 megapixels. On a format this small there is little reason to go lower. |
| 600 | 3496 × 4961 px | Foil, letterpress and engraved detail, or scans of small type. | About 17.3 megapixels — nearly as many as an A3 page at 300 DPI, for a sheet an eighth of the area. Rarely justified on a flyer. |
Figures are rounded to the nearest whole pixel from 148 × 210 mm, the official ISO 216 dimensions — not from the 148.5 mm you get by halving an A4 exactly.
At 300 DPI, A5 is 1748 × 2480 px portrait. Because flyers get read at arm’s length, this is one format where the full print resolution is genuinely worth it — text and fine rules show their edges much more than they would on a poster.
Two, side by side. A5 is exactly half of A4, so print shops often impose two A5 pages onto a single A4 sheet and cut them apart afterwards. If you supply the pages separately at 148 × 210 mm, the printer handles that arrangement for you.
No — A5 is noticeably bigger. A5 is 148 × 210 mm (1748 × 2480 px at 300 DPI), while a standard postcard is 100 × 148 mm (1181 × 1748 px). The postcard is closer to A6, which is 105 × 148 mm.
A spread is two A5 pages side by side, so 296 × 210 mm — 3496 × 2480 px at 300 DPI. Design the spread as one canvas when artwork crosses the fold, and export single pages if your printer asks for them that way.
Yes, and the proportions match exactly, so nothing gets cropped. Just remember that type scales down with everything else: 10 pt body text on the A4 version ends up around 7 pt on the A5, which is below comfortable reading size for most print work.
A5 at 72 DPI is 420 × 595 px. It is a small file, fine for a web preview or an email attachment, but far too coarse to send to a printer — at that resolution a printed A5 would show visible pixel edges on any text.
Because ISO 216 rounds every dimension down to a whole millimetre. Halving A4’s 297 mm long side gives exactly 148.5 mm, but the published A5 width is 148 mm. At 300 DPI the difference is 1754 px against 1748 px — six pixels, invisible on a single flyer and quite visible as a repeating misalignment once you impose several pages onto one sheet. Build from the A5 preset rather than from a folded A4 and it never comes up.
Because the pages are not printed one at a time. Each A4 sheet carries two A5 pages per side, so folding and stitching it produces four pages at once. A 14-page A5 booklet has to become 16, with two blanks, or lose two pages. Plan the running order in fours from the start — it is much cheaper than discovering it at imposition.
3 mm on all four sides is standard, which makes the sheet 154 × 216 mm — 1819 × 2551 px at 300 DPI, or 71 px more on each axis than the trimmed page. Convert the bleed-inclusive size in one step rather than adding a converted 3 mm twice: 3 mm rounds to 35 px, and 1748 + 35 + 35 comes to 1818 px, one pixel short.
At least 1748 × 2480 px for the trimmed page, or 1819 × 2551 px if it bleeds off the edge. Below that you are enlarging: a 1200 px wide image spread over the 148 mm width comes out at roughly 206 DPI, which reads as soft on a sheet held at arm’s length even though the same figure would be fine on a wall poster.
A5 at 150 DPI is 874 × 1240 px. It is enough for an office-laser proof, and not enough for a delivered flyer — A5 gets read at about 30 cm, close enough that 150 DPI type shows soft edges and thin rules break up. Use it to check the layout, then export the real file at 300 DPI.
