METHOD & EXAMPLES

Know what goes into the result.

The print-size formula

PPI means pixels per inch of the printed image. Divide pixel dimensions by PPI to get inches; multiply inches by 2.54 for centimeters or 25.4 for millimeters. In the reverse direction, multiply inches by PPI and round up to a whole pixel.

print width in inches = image width in pixels ÷ PPI

Worked exampleA 3000 × 2400 image at 300 PPI measures 10 × 8 inches, or 25.4 × 20.32 cm. An 8 × 10 inch print at 300 PPI requires 2400 × 3000 pixels.

PPI, DPI and the limits of a calculation

PPI describes image pixels at a physical size; DPI describes printer dots. These are different measurements. Changing a density label does not add detail to an image. Print quality also depends on the original photograph, paper, printing process and viewing distance. The presets are starting points; ask your printer for its requirements.

Try this workflow

Start with
A 4 × 6 inch print.
Set up
Choose print-to-pixels and 300 PPI.
What to expect
The required image is 1200 × 1800 pixels. Apply dimensions transfers this result to Resize Image; enlargement still cannot create accurate missing detail.

Check before using the result

  • Confirm the print provider’s PPI and bleed requirements.
  • Match the print proportions to avoid unexpected cropping.

When the result needs work

Printer DPI and image PPI describe different things. Changing a resolution tag alone does not add image pixels.

More help

How large can I print a 3000 × 2400 image at 300 PPI?

At that density, the dimensions are 10 × 8 inches, equal to 25.4 × 20.32 centimeters. This is a dimension calculation, not a guarantee of print quality.

Are PPI and DPI the same?

PPI is the number of image pixels per inch at the print size. DPI describes the printer’s ink or toner dots per inch. A printer can use multiple dots to represent an image pixel.

Does setting 300 PPI improve a low-resolution photo?

No. A density setting changes the relationship between pixels and physical size. It does not create missing detail. The calculator shows how many pixels a proposed print requires.

Why are the required pixel dimensions rounded up?

Images use whole pixels. Rounding up avoids returning fewer pixels than the chosen size and density require.
