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.
