Understanding PX to CM Conversion
How Does the Conversion Work?
The conversion from pixels to centimeters depends on the DPI (dots per inch) or PPI (pixels per inch) setting. Here's the formula:
Centimeters = (Pixels ÷ DPI) × 2.54
The factor 2.54 comes from the conversion: 1 inch = 2.54 centimeters.
Common DPI Standards
- 72 DPI: Old web standard (macOS default before Retina). Rarely used today.
- 96 DPI: Modern web standard (Windows default). Most common for digital displays.
- 150 DPI: Low-quality print. Acceptable for draft prints or large-format posters viewed from distance.
- 300 DPI: Standard print quality. Professional photos, magazines, brochures.
- 600 DPI: High-quality print. Fine art prints, detailed graphics, text-heavy documents.
Why Does DPI Matter?
A 1920px image will be 50.8 cm wide at 96 DPI (web), but only 16.3 cm wide at 300 DPI (print). The physical size changes dramatically based on DPI.
Real-World Examples
- Web Design: A 1200px wide website at 96 DPI = 31.75 cm (roughly A4 width). Use 96 DPI for web conversions.
- Print Design: An A4 page (21 cm wide) at 300 DPI = 2480 pixels. Always work at 300 DPI for print.
- Social Media: Instagram feed post (1080px) at 96 DPI = 28.58 cm. Physical print would be much smaller at 300 DPI (9.14 cm).
- Business Cards: Standard 8.5×5.5 cm card at 300 DPI = 1004×650 pixels.
When to Use This Converter
