When to use it
Build the complete specification before export
Use the full calculator when trim size, resolution and finishing margins need to agree in one document.
Check an existing image
Enter its pixel dimensions to calculate the effective resolution at your chosen physical print size.
Protect important content
Calculate the internal safe area so text, logos and key details do not sit too close to the intended cut.
Three checks, one answer
What this calculator works out
Pixels from print size
Physical width and height are converted to inches, then multiplied by the selected DPI.
Bleed and safe area
Bleed expands every edge of the document. Safe margin keeps important content away from the trim line.
Image resolution
Effective DPI compares your image pixels with the intended physical print dimensions.

Trim size, bleed and pixels at 300 PPI
These examples use common planning bleed values. Production requirements vary, so replace them with the exact specification supplied by the printer.
| Final trim | Bleed per side | Full document | Pixels 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 |
| A4 | 3 mm | 216 × 303 mm | 2551 × 3579 px |
| A3 | 3 mm | 303 × 426 mm | 3579 × 5031 px |
Pixel values are rounded to the nearest whole pixel. Bleed adds twice the per-side amount to both the width and height.

Common print setup mistakes
Making the trim size larger
Bleed expands the working document, not the finished product. The trim size remains the final cut dimensions.
Using bleed as a safe margin
Bleed sits outside trim; the safe area sits inside it. They solve different production risks and should be calculated separately.
Trusting a DPI label alone
Effective resolution comes from pixels divided by final inches. Changing metadata without adding real detail does not improve it.
Print size calculator FAQ
Does adding bleed change the trim size?
No. The trim size is the final finished size. Bleed adds extra artwork beyond every trim edge, making the working document larger.
Is 300 DPI always required?
No. It is a common target for close-viewed quality printing, but large posters viewed from farther away can often use a lower effective resolution. Follow your printer's specification.
Are my images uploaded?
No. You enter only the pixel dimensions. All calculations happen in your browser and no design file is uploaded.
How much bleed should I add?
Use the exact value supplied by the printer or publisher. Values such as 3 mm or 0.125 inch are common, but they are not universal.
Does the pixel result include bleed?
The main required pixel size describes the final trim. The document-with-bleed result shows the larger working dimensions; convert that full size when creating a raster document.
