Image size depends on pixels and DPI (dots per inch).
The formula:
- Size in inches = Pixels / DPI
- Size in cm = Pixels / DPI × 2.54
- Pixels needed = Size in inches × DPI
Common DPI values:
- 72 DPI — Screen/web display (standard monitor)
- 150 DPI — Draft quality print
- 300 DPI — High quality print (photos, brochures)
- 600 DPI — Professional/fine art print
Example (1920 px wide image):
- At 72 DPI: 26.67 inches (67.7 cm) — great for web
- At 150 DPI: 12.8 inches (32.5 cm) — decent print
- At 300 DPI: 6.4 inches (16.3 cm) — high quality print
Standard print sizes:
- 4×6 in (10×15 cm) at 300 DPI needs: 1200×1800 px
- 8×10 in (20×25 cm) at 300 DPI needs: 2400×3000 px
- A4 (21×29.7 cm) at 300 DPI needs: 2480×3508 px
