Pixels to Inches Converter

Why this conversion needs a DPI value

A pixel has no fixed physical size — it only becomes a measurable length once you know the resolution (dots per inch, DPI) it's being rendered or printed at. The formula here is inches = pixels / DPI. That's why this tool asks for a DPI figure alongside the pixel count, defaulting to 96, the standard baseline resolution most web browsers use for CSS pixel-to-inch assumptions.

Worked example

A 960px-wide image at the default 96 DPI converts to 960 / 96 = 10.000 inches wide. The same 960 pixels at 300 DPI (a common print resolution) converts to 960 / 300 = 3.200 inches — less than a third the size, because a higher DPI packs more pixels into each inch.

Which DPI to use

96 DPI is the long-standing web/CSS reference resolution. Most home inkjet/laser printing targets 300 DPI for photo-quality output. Professional print (magazines, books) often specifies 300–600 DPI. If you're sizing an image for print rather than screen display, swap the default 96 for the actual print DPI your project requires — using the web default for a print job will make your inch estimate roughly 3x too large.

Where this comes up

Checking whether a screenshot or exported graphic will print at the physical size you expect, converting a designer's pixel-based spec into a print dimension, or verifying that an image has enough resolution (pixels) to reach a target physical size at print DPI without appearing blurry.
