How do I choose a preset or custom print trim with bleed?

Open Change Trim Size and choose one of the common inch or millimeter presets, or select Custom Size. For a custom trim, choose inches or millimeters and enter the final width, height, and bleed requested by your printer.

Bleed is the extra artwork extending beyond the cut edge so trimming does not leave a white line. The editor supports custom inch sizes from 4 to 8.5 inches wide and 7 to 10.1 inches high with up to 0.15 inch bleed, or 102 to 216 mm wide and 178 to 257 mm high with up to 4 mm bleed.
