Pixels to Inches Calculator

You divide the pixel count by the PPI, so inches = pixels ÷ PPI. The catch is that a pixel has no fixed physical size, which is why the PPI matters so much. The same 1000 pixels are 10.42 inches on a 96 PPI monitor but only 3.33 inches when printed at 300 DPI. That's why this calculator asks for the PPI up front instead of pretending one magic number covers every screen and printer.

Use 300 DPI for photos, cards, and anything viewed at arm's length, since that's the standard where individual pixels stop being visible. You can drop to 150 DPI for large posters and banners because they're viewed from farther away, and the softness isn't noticeable at that distance. Anything below 150 DPI starts to look pixelated up close, and 72 or 96 DPI is really a screen setting, not a print one.

Strictly no, but in practice they're used interchangeably. PPI means pixels per inch and describes digital image density, while DPI means dots per inch and describes the ink dots a printer lays down. When a print lab asks for a 300 DPI file, they mean 300 PPI, and this calculator treats the two the same way. The distinction only matters deep inside printer specs, where one pixel is built from many ink dots.

A 12 MP photo is about 4000 x 3000 pixels, which prints at 13.3 x 10 inches at 300 DPI, so a sharp 11 x 14 is comfortably within reach. If it'll hang on a wall and be viewed from a few feet away, 150 DPI is fine and the same file stretches to 26.7 x 20 inches. Enter your exact pixel dimensions in the print size mode above and you'll see both figures instantly.

Screens only pack around 96 to 110 pixels into each inch, while a good print needs about 300. An image that fills your monitor edge to edge might be 1920 x 1080, which is just 6.4 x 3.6 inches at print quality. Blown up to an 8 x 10, those pixels get stretched to roughly 2.5 times their intended size, and that's the blur you're seeing. The screen was hiding it because it never asked for that density.

Multiply each side by the DPI: at 300 DPI you need 2400 x 3000 pixels, which is 7.2 megapixels. At 150 DPI for a more casual print, 1200 x 1500 pixels will do. Any modern phone clears the 300 DPI bar for an 8 x 10 easily, but heavy cropping eats pixels fast, so check the dimensions of the cropped file, not the original, before you send it off.

Only if resampling is on. With resampling off, changing 72 DPI to 300 DPI just rewrites a metadata tag that tells printers how large to output the file; every pixel stays untouched and nothing is gained or lost. With resampling on, the editor invents new pixels or throws pixels away to hit the new size, and invented pixels never add real detail. If a lab asks for 300 DPI, resize without resampling first and see what print size that gives you.
