1 Inch to Pixels

1 inch is 300 pixels at 300 DPI, 150 pixels at 150 DPI and 96 pixels at the 96 PPI screen standard.

1 inch 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 1 inch at 300 DPI that is 1 × 300 = 300.

1 inch is a single edge, so the density alone decides the pixel count.

A print at this size is held or read close up, where 300 DPI is the density to work to, which puts it at 300 pixels at 300 DPI and 150 at 150.

In metric, 1 inch is 2.54 cm or 25.4 mm, and in typographic units it is 72 points.

Frequently asked questions

How many pixels is 1 inch?

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

How many pixels is 1 inch at 300 DPI?

300 pixels. That is the standard density for photographic and magazine printing.

What is 1 inch in centimetres?

2.54 cm, because one inch is exactly 2.54 centimetres.

Is 300 DPI the right density for this size?

Yes. At this size the finished piece is held or read close up, which is exactly what the 300 DPI standard is for — 300 pixels. Dropping to 150 halves that to 150 and the softening is visible in the hand.

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.
