Quick Reference

Common pixel-to-inch conversions at different DPIs

Pixels (px) @ 72 DPI @ 96 DPI @ 300 DPI
300 px 4.17 in 3.13 in 1.00 in
600 px 8.33 in 6.25 in 2.00 in
1200 px 16.67 in 12.50 in 4.00 in
1920 px 26.67 in 20.00 in 6.40 in
3840 px 53.33 in 40.00 in 12.80 in

Understanding PX to Inches Conversion

The Simple Formula

Inches = Pixels ÷ DPI

For example: 1920 pixels ÷ 96 DPI = 20 inches

Why DPI Changes Everything

The same 1920px image will be:

  • 26.67 inches at 72 DPI (old Mac standard)
  • 20 inches at 96 DPI (Windows/web standard)
  • 6.4 inches at 300 DPI (print standard)

Common Use Cases

  • Monitor Sizes: A 24" monitor with 1920×1080 resolution = 92 PPI. Each pixel is about 0.011 inches.
  • Print Photos: Standard 4×6" photo at 300 DPI = 1200×1800 pixels.
  • Business Cards: 3.5×2" card at 300 DPI = 1050×600 pixels.
  • Posters: 18×24" poster at 150 DPI = 2700×3600 pixels.

Screen vs. Print

Web/Screen: Use 72-96 DPI. Physical size matters less since viewers adjust screen distance.

Print: Use 300 DPI minimum. Physical size is critical — a 4×6" print must be exactly 4×6 inches.

Pro Tips

  • Retina/High-DPI displays: Modern screens (iPhone, MacBook) have 200-400+ PPI. Design at 2× or 3× size for sharp rendering.
  • Aspect ratio matters: 1920×1080 (16:9) at 96 DPI = 20×11.25 inches. Width and height convert independently.
  • Viewing distance: Billboards use 10-50 DPI because they're viewed from far away. Closer viewing = higher DPI needed.
