Enter your finished size and bleed to get the document size, the safe area, and a visual guide — no more white edges after trimming.
Getting bleed right is what stops a printed piece having thin white edges. Bleed is artwork extended beyond the trim line — typically 3 mm on every side — so a slightly off cut still lands on your design. This bleed calculator gives you the exact document size to build (finished size + bleed all round), the safe area to keep text inside, and a visual guide showing the bleed, trim and safe lines.
Build your document at the size-with-bleed, extend backgrounds and images to that edge, and keep all important text and logos inside the safe area. Export a print PDF with crop marks and bleed so the printer knows exactly where to trim. Standard bleed is 3 mm; large format often uses more.
