✂️ Print Bleed Calculator
Enter your finished trim size and the bleed per side to get the full artboard dimensions — set your document to this size so artwork runs cleanly off the edge with no white slivers after cutting.
🧮 Add Bleed to Your Design
What is a Print Bleed Calculator?
It takes the finished trim size of a card, flyer, or poster and adds the bleed margin to every side, giving you the full artboard size to build your file at. Because bleed is added to each edge, the tool doubles it when it grows the width and height — so you don't have to do the arithmetic by hand.
Set your design document to the size it returns, extend any edge-to-edge colour and images into the bleed, and keep text inside the safe area. Always confirm the exact bleed your printer wants before you export.
❓ Frequently Asked Questions
How does the print bleed calculator work?
Bleed is added to every side of a design, so each dimension grows by twice the bleed: total = dimension + 2 × bleed. Enter your finished trim size and the bleed amount and it returns the full artboard size to set your document to — for example a 6×4 card with 0.125 in bleed becomes 6.25 × 4.25.
What is bleed and why do I need it?
Bleed is the extra artwork that extends past the trim line so that when the printer cuts the sheet, any slight movement doesn't leave a thin white strip at the edge. Any design where colour or images run to the edge of the page needs bleed.
How much bleed should I use?
0.125 inch (3 mm) is the most common standard, but it varies by printer and product — some large-format or specialty jobs want 0.25 inch or more. Always check your printer's template or spec sheet and enter their exact figure here.
What's the difference between bleed, trim, and safe area?
Trim is the finished cut size of the piece. Bleed is the extra artwork extending beyond the trim so nothing white shows after cutting. The safe area is an inset inside the trim where you keep important text and logos, so they aren't clipped if the cut drifts. This tool calculates the bleed (outer) size.
