When to use it
Start with the result you need
This calculator is most useful when one part of the print specification is known and another needs to be checked.
Check a printer template
Compare the supplied trim and bleed specification with your document dimensions before export.
Protect text and logos
Use the safe-area result to keep important content away from the cutting tolerance.
The calculation
How it works
Add bleed twice to each trim dimension: document width = trim width + (2 × bleed). Use the same calculation for height because bleed extends beyond both opposite edges.
Safe margin works in the opposite direction. Subtract it twice from the trim dimensions to find the internal area for critical content.
Quick reference
Example document sizes with bleed
These examples illustrate the calculation only. Use the exact bleed specified for your job.
| Final trim | Bleed per side | Full document | At 300 PPI |
|---|---|---|---|
| 4 × 6 in | 0.125 in | 4.25 × 6.25 in | 1275 × 1875 px |
| 8 × 10 in | 0.125 in | 8.25 × 10.25 in | 2475 × 3075 px |
| A5 | 3 mm | 154 × 216 mm | 1819 × 2551 px |
| A4 | 3 mm | 216 × 303 mm | 2551 × 3579 px |
| A3 | 3 mm | 303 × 426 mm | 3579 × 5031 px |
The full document is larger than the finished trim on every edge.
Check the numbers
A4 with 3 mm bleed
A 210 × 297 mm trim becomes a 216 × 303 mm document because 3 mm is added to both sides of each dimension.
8 × 10 in with 0.125 in bleed
The working document is 8.25 × 10.25 inches, while the final cut remains exactly 8 × 10 inches.
Safe margin of 5 mm on A4
The central safe content area is 200 × 287 mm after subtracting 5 mm from all four edges.
Before you export
Common mistakes to avoid
Adding bleed only once
A per-side value must be added to both opposite edges, so each full dimension increases by twice the bleed.
Putting white space in the bleed
Bleed must continue the edge artwork; an empty border cannot prevent white slivers after cutting.
Treating safe margin as bleed
Bleed is outside trim and safe margin is inside it. They protect against different production risks.
Add bleed without changing the final trim size. FAQ
How much bleed should I use?
Use the printer’s specification. Values such as 3 mm and 0.125 inch are common, but they are not universal.
Does bleed change the finished size?
No. Bleed makes the working document larger. The trim line still defines the final finished dimensions.
Should photos extend into bleed?
Yes, when they touch a finished edge. Extend the image through the full bleed area rather than adding a separate border.
