Pixels ↔ cm/inches Converter (by DPI)
Convert pixels to physical size for a given DPI — for print layout, photo sizing and CSS.
Pixels have no physical size until you pick a DPI — the same 1080px is 9.1 cm at 300 DPI (print) but 28.6 cm at 96 DPI (old web standard). For sharp prints, photo labs want 300 DPI, so a 1080px image prints crisply only up to ~9 cm wide. CSS pixels are a different beast (device-independent), which is why web design uses 96 as the nominal reference.
