DPI / Pixel Size Calculator
Convert between pixel dimensions, physical size (inches or centimeters) and DPI using the standard print formula: pixels = inches × DPI.
Edit any field, pixels = inches × DPI, the other three update automatically.
1200 px at 300 DPI ≈ 4 in (10.16 cm)
Frequently asked questions
What DPI should I use for printing?
300 DPI is the standard for high-quality print (photos, brochures, business cards). 150 DPI is acceptable for large-format prints viewed from a distance, like posters. Anything below 150 DPI tends to look visibly pixelated up close.
What DPI should I use for screens?
Screens are typically measured in pixels, not DPI, but 72-96 DPI is the traditional web/screen reference resolution used for things like converting a print layout size to on-screen pixels.
How do I find out what size I can print an image at?
Enter the image's pixel dimensions and your target DPI (300 for quality print), the tool calculates the resulting physical size in inches and centimeters, so you know the largest size you can print without losing sharpness.
