How to Convert Inches to Pixels
A practical guide to converting inches to pixels with worked examples for web, Windows, and print designs.
The Formula
The formula is simple: pixels = inches × DPI. Choose your DPI, multiply by your inch measurement, and you get the pixel count.
Worked Examples
- Web (72 DPI): 4 inches = 4 × 72 = 288 pixels
- Windows/CSS (96 DPI): 4 inches = 4 × 96 = 384 pixels
- Print (300 DPI): 4 inches = 4 × 300 = 1,200 pixels
- US Letter at 300 DPI: 8.5 × 11 inches = 2,550 × 3,300 pixels
Reverse Conversion
To convert pixels back to inches, use inches = pixels ÷ DPI. For example, 1,200 pixels at 300 DPI = 4 inches.
