15 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 15 inches at 300 DPI that is 15 × 300 = 4,500.

15 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 4,500 pixels at 300 DPI and 2,250 at 150.

In metric, 15 inches is 38.1 cm or 381 mm, and in typographic units it is 1,080 points.

Frequently asked questions

How many pixels is 15 inches?

4,500 pixels at 300 DPI, 2,250 at 150 DPI and 1,440 at the 96 PPI screen standard. Multiply the inches by whichever density you are working to.

How many pixels is 15 inches at 300 DPI?

4,500 pixels. That is the standard density for photographic and magazine printing.

What is 15 inches in centimetres?

38.1 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 2,250 pixels rather than 4,500 — 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.
