The working
Pixels are inches multiplied by the resolution, and an inch is 25.4 mm.
- Width: 74 mm ÷ 25.4 = 2.913 in; 2.913 in × 600 = 1,748, which rounds to 1748 pixels.
- Height: 105 mm ÷ 25.4 = 4.134 in; 4.134 in × 600 = 2,480.3, which rounds to 2480 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 1890 × 2622 pixels.
Is your photo big enough?
To fill A7 at 600 DPI an image needs at least 1748 × 2480 pixels. Cropped to fill the sheet:
- A 12 megapixel phone photo (4000 × 3000) gives 968 DPI: enough.
- A 24 megapixel camera photo (6000 × 4000) gives 1,373 DPI: enough.
- A 48 megapixel photo (8000 × 6000) gives 1,935 DPI: enough.
At 600 DPI the pixels of a print blend together from about 5.7 inches (15 cm) away. 600 DPI is used for line art, small text and scans that will be enlarged. It is also the native resolution of many office laser printers.
