Convert pixels to inches and centimeters according to the entered DPI (72, 96, 150, 300 and 600). The conversion depends on the resolution (DPI).
Conversion between pixels and inches depends on image resolution, measured in DPI (dots per inch) or PPI (pixels per inch). A pixel has no fixed physical size — it only gains a real dimension when associated with a resolution. That is why 600 pixels equal 2 inches at 300 DPI, but 6.25 inches at 96 DPI. The basic formula is: inches = pixels ÷ DPI; and pixels = inches × DPI. For centimeters, 1 inch = 2.54 cm, so centimeters = inches × 2.54 = pixels ÷ DPI × 2.54. This converter offers the most common DPIs: 72 (old screens), 96 (web/CSS standard), 150 (draft printing), 300 (photo-quality printing), and 600 (high-resolution printing). It is essential to understand that the conversion depends on the entered DPI — that is why units are separated by resolution. Select the same resolution in the source and target units to get the correct result. It is useful for designers, photographers, printing and graphic arts professionals, and anyone who needs to size images between digital and physical media.
Divide pixels by DPI. E.g., 600 px at 300 DPI = 600 ÷ 300 = 2 inches.
1 inch at 96 DPI = 96 pixels (web/CSS standard).
DPI (dots per inch) refers to print dots; PPI (pixels per inch) refers to screen pixels. In practice, the conversion values are the same.
Because a pixel has no fixed physical size. The real dimension only appears when pixels are associated with a resolution (DPI/PPI).
