Print bleed size calculator

Bleed is artwork you expect to cut off

If a background must reach the paper edge, the artwork needs to extend beyond the final trim line. This calculator adds the bleed to the finished width and height.

Bleed is not a margin

This is the part that often causes confusion: bleed goes outside the trim, while important text and logos should stay safely inside it. They solve opposite problems.

Before you use a familiar 3 mm value

• Check the printer’s actual specification.
• A 3 mm bleed on each side adds 6 mm to the total width and 6 mm to the height.
• Use the printer’s final template when one is provided.

A4 example

A4 is 210 × 297 mm. With 3 mm bleed on all four sides, the full artwork size becomes 216 × 303 mm.
