Understanding the Centimeters (CM)
- Centimeters (96 PPI): This column shows the centimeter equivalent for a standard PPI of 96, common in web design.
- Centimeters (300 PPI): This column shows the centimeter equivalent for a PPI of 300, common for high-quality printing.
The Role of PPI (Pixels Per Inches)
The conversion isn’t a direct 1:1 relationship. Here’s why:
- PPI (Pixels Per Inches): PPI indicates the pixel density of a screen or image. A higher PPI means more pixels in the same physical space, resulting in a sharper image.
- To convert pixels to centimeters, you MUST know the PPI of the image or the intended display device.
Conversion Formula
The basic formula for the conversion is:
Size (cm) = Size (px) / PPI * 2.54
Where:
- 2.54 is the conversion factor between inches and centimeters.
