Set up A8 artwork without guessing

Start the document at the finished size—52 × 74 mm—and add the bleed your printer specifies outside that edge. A common 3 mm bleed produces a 58 × 80 mm artwork canvas. Keep type, logos, folds, and other critical details inside the trim line; a safety margin is not the same thing as bleed.

Pixel dimensions only become meaningful when paired with a resolution. At 300 DPI, this format is 615 × 873 pixels. Changing that number in an export dialog without resampling does not add image detail—it only changes the declared physical scale.

A8 belongs to ISO A Series. Its proportion is 1:1.414 (√2); the √2 family is designed so a half-sheet keeps the same shape, which makes layouts easier to scale between related formats.
