Start the document at the finished size—210 × 297 mm—and add the bleed your printer specifies outside that edge. A common 3 mm bleed produces a 216 × 303 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 2,481 × 3,507 pixels. Changing that number in an export dialog without resampling does not add image detail—it only changes the declared physical scale.
A4 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.
