Formula breakdown
Formula
bleed size = trim size + 2 × bleed per edge= 216
Note
Simplified model: these are standard prepress and typographic relationships computed on nominal values. Real press bulk, paper caliper and shrinkage, ink limits for a given profile, font metrics and binding allowances vary by supplier and by job, so confirm with your printer and a proof before going to press.

What's the difference between bleed size, trim size, and safe area?+
Trim size is the final, cut dimension of the printed piece. Bleed size is larger than trim (typically by 0.125 inch / 3mm per side) and includes extra background that gets cut off, preventing white edges from slight cutting misalignment. The safe area sits inside the trim line, keeping important text and logos away from the cut edge.
Why do I need bleed if my printer cuts precisely?+
Even precise cutters have a small margin of mechanical tolerance, and print jobs are often stacked and cut in batches, increasing drift. Without bleed, any tiny shift reveals an unprinted white sliver along the edge instead of your intended color or image.
How much bleed should I add?+
0.125 inch (3mm) per edge is the print industry standard for most jobs like business cards, flyers, and brochures; large-format work like banners sometimes uses more. Always check your specific printer's requirements since some vary.
Do I need to add bleed on every side of my document?+
Only on edges where your design's background or imagery extends to the edge of the page. An edge with a white background and no bleed-sensitive content technically doesn't need bleed, but adding it uniformly is simpler and safer.
My design got cut off after adding bleed — what went wrong?+
Important content was likely placed too close to the trim line rather than inside the safe area. Bleed protects the background from showing white gaps, but it doesn't protect your text or logo from being clipped if it sits right at the edge.
