What Is Bleed in Printing? (With Correct Sizes for SA Templates)
What Is Bleed in Printing? (With Correct Sizes for SA Templates)
Bleed is extra background that extends 2 to 3mm past the edge of your design, so that when the
printed sheet is trimmed to size, color runs cleanly to the edge with no white slivers. If your design
has any color, image or pattern touching the edge, it needs bleed. If everything sits on a white
background well inside the edges, it technically does not — but set it up anyway, because habits beat
exceptions.
Why do printers insist on bleed?
Because trimming is a mechanical process with real-world tolerance. Guillotines cut through stacks of
hundreds of sheets, and the blade can land a fraction of a millimeter either side of the intended line.
Without bleed, a cut that drifts 0.5mm outward exposes a hair-thin white line along one edge — and
once you have seen it, you cannot unsee it. With bleed, the same drift just trims off a sliver of extra
background and nobody ever knows.
Bleed is not the printer being fussy. It is the difference between a professional-looking edge and a job
that looks like it was cut at home.
What are the correct bleed sizes for South African print jobs?
The standard here is 2mm bleed on small items and 3mm on larger ones. Your document size with
bleed included:
• Business card (90 x 50mm): design at 94 x 54mm
• A6 flyer (105 x 148mm): design at 109 x 152mm
• A5 flyer (148 x 210mm): design at 152 x 214mm
• A4 flyer or poster (210 x 297mm): design at 216 x 303mm
• DL (99 x 210mm): design at 103 x 214mm
What is the safe zone, and how is it different from bleed?
Bleed protects the outside edge; the safe zone protects your content. Keep all text, logos and
anything you cannot afford to lose at least 3mm inside the trim line. The same cutting tolerance that
can expose white edges can also shave off content sitting flush against the edge.
So, a design really has three boxes: the bleed box (biggest), the trim line (final size), and the safe
zone (smallest). Background fills the bleed box; content stays inside the safe zone; nothing important
lives between them.
How do I add bleed in Canva, Word or InDesign?
Canva: File → Settings → Show print bleed, then tick "Crop marks and bleed" when downloading the
PDF. Also drag any edge-touching backgrounds out to the bleed line — Canva shows it as a dotted
border.
InDesign or Illustrator: Set bleed in Document Setup (2 or 3mm all round) and include it when
exporting the PDF, along with crop marks.
Word: Word has no real bleed support. It works for internal documents, but for anything
professionally printed, use Canva or proper design software — or design your page slightly oversized
and let us advise.
FAQ
My design has a white background. Do I still need bleed?
Strictly, no — white paper trimmed to white background shows nothing. But send the file at the
correct final size with no stray marks near the edges, and consider setting up bleed anyway so the
habit is there when you design something with color.
What happens if I send a file without bleed?
We flag it and it comes back to you, which costs a day or two. In some cases, we can slightly enlarge
the artwork to create artificial bleed, but that shifts your safe zone and can crop content — a fix of last
resort, not a plan.
Is bleed the same as a border?
No, and borders deserve their own warning: a thin border close to the trim edge is the hardest design
to cut perfectly, because any drift makes the border visibly uneven. If you want a border, make it
generous — 5mm or more from the edge.
Do I need crop marks?
Include them if your software offers it. They show exactly where the trim line sits. Bleed without crop
marks is workable; crop marks without bleed are not.
