12.5 inches in pixels at every common resolution

The pixel count changes with the resolution you are working to — these are the values you are most likely to need.

How the conversion works

Pixels are found by multiplying the length in inches by the pixel density: pixels = inches × DPI. For 12.5 inches at 300 DPI that is 12.5 × 300 = 3,750.

12.5 inches is a single edge, so the density alone decides the pixel count.

A print at this size is usually seen from half a metre or more, where 150 DPI holds up, which puts it at 3,750 pixels at 300 DPI and 1,875 at 150.

In metric, 12.5 inches is 31.75 cm or 317.5 mm, and in typographic units it is 900 points.

Frequently asked questions

How many pixels is 12.5 inches?

3,750 pixels at 300 DPI, 1,875 at 150 DPI and 1,200 at the 96 PPI screen standard. Multiply the inches by whichever density you are working to.

How many pixels is 12.5 inches at 300 DPI?

3,750 pixels. That is the standard density for photographic and magazine printing.

What is 12.5 inches in centimetres?

31.75 cm, because one inch is exactly 2.54 centimetres.

Does this size really need 300 DPI?

Usually not. Something this size is read from about a metre away, and at that distance 150 to 200 DPI is indistinguishable from 300. That is 1,875 pixels rather than 3,750 — a quarter of the file for no visible loss.

Why does the pixel count change with DPI?

A pixel has no fixed physical size. The DPI value says how many pixels fill one inch, so raising it raises the pixel count needed to cover the same physical space.
