The working
Pixels are inches multiplied by the resolution, and an inch is 25.4 mm.
- Width: 148 mm ÷ 25.4 = 5.827 in; 5.827 in × 72 = 419.5, which rounds to 420 pixels.
- Height: 210 mm ÷ 25.4 = 8.268 in; 8.268 in × 72 = 595.3, which rounds to 595 pixels.
Bleed is extra image past the trim line, so that a cut that lands slightly off still leaves ink to the edge. Print shops usually ask for 3 mm on every side of an A-series page, which makes the file 437 × 612 pixels.
Is your photo big enough?
To fill A5 at 72 DPI an image needs at least 420 × 595 pixels. Cropped to fill the sheet:
- A 12 megapixel phone photo (4000 × 3000) gives 484 DPI: enough.
- A 24 megapixel camera photo (6000 × 4000) gives 686 DPI: enough.
- A 48 megapixel photo (8000 × 6000) gives 968 DPI: enough.
At 72 DPI the pixels of a print blend together from about 47.7 inches (121 cm) away. 72 DPI is the old screen convention: early Macintosh displays showed 72 pixels to the inch, matching the 72 points in an inch of type. Many image files still carry a 72 DPI tag for that reason.
