Understanding Centimeters vs Pixels

While digital images are measured in pixels, printed images are measured in physical units like centimeters or inches. The connection between these measurements is DPI (dots per inch) or PPI (pixels per inch). For example, a 10cm x 10cm image at 300 DPI equals approximately 1181 x 1181 pixels.

Common DPI Settings

  • 72 DPI: Standard for web and screen display
  • 150 DPI: Minimum for acceptable print quality
  • 300 DPI: Professional printing standard (recommended)
  • 600 DPI: High-quality professional printing and art reproduction

Frequently Asked Questions

How do centimeters relate to pixels?

The relationship depends on DPI (dots per inch). To convert: pixels = (cm × DPI) / 2.54. For example, 10cm at 300 DPI = (10 × 300) / 2.54 ≈ 1181 pixels. Our tool handles this conversion automatically, so you only need to enter your desired centimeter dimensions and DPI.

What DPI should I use for printing?

For professional printing, use 300 DPI. This is the industry standard and ensures sharp, high-quality prints. For draft prints or large posters viewed from a distance, 150 DPI may be acceptable. Never use less than 150 DPI for prints, as they'll appear pixelated. For web use only, 72 DPI is sufficient.
