Pixels to Inches Converter
Convert pixels to inches, centimeters, or millimeters at any DPI/PPI — for print, design, and screen sizing.
Frequently Asked Questions
How many pixels are in an inch?
There is no single fixed answer — it depends entirely on the resolution (DPI/PPI) of the screen or printer. At the common web standard of 96 DPI, 1 inch = 96 pixels. At 300 DPI (standard print resolution), 1 inch = 300 pixels. At Retina/HiDPI screen densities (220–326 PPI), 1 inch can be 220–326 pixels. Always check the DPI you need before converting.
What DPI should I use for print vs. screen design?
For print, use 300 DPI for sharp, professional results (some fine-detail print jobs use 600 DPI). For standard web/screen design, 96 DPI is the long-standing CSS reference resolution. For HiDPI/Retina displays, designers often work at 144 or 192 DPI (2x or interpolated scaling) so images stay crisp on high-density screens.
What is the difference between DPI and PPI?
PPI (pixels per inch) describes the pixel density of a digital screen or image. DPI (dots per inch) technically refers to printed dots from a printer. In casual and design usage the two terms are often used interchangeably, since both measure how many units pack into one inch — but PPI is the more technically correct term for screens and digital images.
How do I convert a pixel dimension to inches for printing?
Divide the pixel dimension by your target print DPI. Example: a 1500 × 1200 px image printed at 300 DPI yields 1500 ÷ 300 = 5 inches by 1200 ÷ 300 = 4 inches. If you print the same image at 150 DPI, it would be twice as large physically (10 × 8 inches) but with half the sharpness.
Why does the same pixel value look different sizes on different screens?
Because screens pack different numbers of physical pixels into each inch. A 1920px-wide image fills the entire width of a 96 PPI monitor at 20 inches, but only a fraction of the width of a 326 PPI smartphone screen, where it would render at roughly 5.9 inches wide. This is why "pixels" alone never describe a physical size — the DPI/PPI is required.
