Pixels to Inches Converter
Convert pixels to inches, centimeters, or millimeters at any DPI/PPI — for print, design, and screen sizing.
Everyday Uses
Print-ready images
Will a 3,000×2,000 px photo print sharply at 8×10"? Convert at 300 DPI and know before wasting paper.
Ordering photo prints
Check whether phone photos have enough pixels for large canvas prints before ordering.
Design for screens vs print
Designers moving between web (72–96 PPI) and print (300 DPI) can convert dimensions without rule-of-thumb errors.
Document scanning
Scanning at 600 DPI? Convert to see the pixel dimensions and file size implications first.
Print sizing
Convert pixel dimensions to physical size at a given DPI to check an image will print sharply rather than pixelated.
Screen design
Work out how large a UI element will appear physically on displays of different pixel densities.

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.
