A5 Print Guide
Everything you need to print A5 Booklet sharp
A5 is half of A4: the size of a paperback page, a party invitation or a flyer handed out on the street. It is also the standard size for notebooks, planner inserts, zines and booklets.
A5 prints are almost always held in the hand and read up close, so 300 DPI matters here, especially for small text. The good news is that A5 needs only 1748 × 2480 pixels, about 4.3 megapixels, which almost any modern camera or phone photo covers.
Where A5 goes wrong is with images saved from the web. A 1080 × 1350 Instagram image gives about 163 DPI at A5: readable, but visibly soft next to sharp text. Upscaling about 1.8× fixes it.

Tips for printing at A5
- Print two per sheet. Two A5 pages fit exactly on one A4 sheet, so you can print at home and cut it in half.
- Keep text as text. For invitations and flyers, export a PDF with live text rather than a flattened image, so the lettering prints crisp at any DPI.
- Add 3 mm bleed for designs that run to the edge: 154 × 216 mm, or 1819 × 2551 pixels at 300 DPI.
A5 questions
How many pixels is A5 at 300 DPI?
1748 × 2480 pixels. At 150 DPI it is 874 × 1240 pixels.
Can I print A5 on A4 paper?
Yes. Place two A5 designs side by side on an A4 page (landscape) and cut down the middle. Most print dialogs also offer a “2 pages per sheet” option.
Is 150 DPI enough for an A5 flyer?
For photos it can be passable, but text and fine lines will look fuzzy because A5 is read from about 30 cm away. Aim for 300 DPI.

Standard Print Sizes & Pixel Resolution
Reference chart of required pixel dimensions for standard photo, poster, and paper formats.
Pixels = Inches × Target DPI
Example for 8×10" at 300 DPI: (8 × 300) = 2400 px width, (10 × 300) = 3000 px height.
Pixels = (Millimeters ÷ 25.4) × Target DPI
Example for A4 (210×297 mm) at 300 DPI: (210 ÷ 25.4 × 300) = 2480 px, (297 ÷ 25.4 × 300) = 3508 px.
