A file has no physical size until a resolution is chosen. The same 3,000 pixels prints at 10.00 inches at 300 DPI and 41.67 inches at 72: nothing about the file changes, only the decision about how densely to place the pixels.

How the Pixels to Inches Calculator works

The same pixel count prints at completely different sizes depending on the resolution chosen. Nothing about the file changes, only the decision about how densely to place the pixels on paper.

Frequently asked questions

How do I convert pixels to inches?

Divide the pixel count by the resolution in DPI. Three thousand pixels at 300 DPI is 10 inches; the same file at 150 DPI is 20 inches.

What resolution should I assume?

None, until you know the output. For print, 300 or 150 depending on viewing distance; for screen, the concept does not really apply because displays vary.

How do I convert to centimetres?

Inches times 2.54. Most European print specifications are given in millimetres, so inches times 25.4 is often more directly useful.

Does the DPI stored in the file matter?

Only as a default suggestion to software. The pixels are the file; the DPI tag is metadata that any application can override.
