Print Resolution
Find the pixel dimensions needed for a given print size and DPI.
About Print Resolution
Each inch of the print needs a fixed number of pixels set by the DPI, so width and height multiply to the total pixel count. Knowing the pixel requirement tells you whether your file can survive a specific print size before you pay for enlargements.
Formula
Print Resolution
Pixels = print size (in) x DPI
- DPI
- Dots per inch, a measure of print sharpness
Worked example
With the default values below, Print Resolution returns Width of 3,000. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
