PX to CM Converter

Pixels (px)cm (96 PPI)cm (300 PPI)

Understanding the Table

  • px: This column represents the number of pixels you want to convert.
  • cm (96 PPI): This column shows the centimeter equivalent for a standard PPI of 96, common in web design.
  • cm (300 PPI): This column shows the centimeter equivalent for a PPI of 300, common for high-quality printing.

Pixels to Centimeters

  • Pixels (px) are the smallest units of a digital image or display. They don’t have an inherent physical size; their real-world dimensions depend on screen resolution.
  • Centimeters (cm): A standard unit of length in the metric system (1 centimeter = 0.01 meters).

Why Convert?

Converting pixels to centimeters is essential when you need to determine the physical size of an image for:

  • Printing: Make sure your digital image translates correctly to the desired print size.
  • Web Design: Ensuring elements display as intended across devices with varying screen resolutions.

The Role of PPI (Pixels Per Inch)

The conversion isn’t a direct 1:1 relationship. Here’s why:

  • PPI (Pixels Per Inch): 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


  • 2.54 is the conversion factor between inches and centimeters.


Let’s say you have an image that is 1000 pixels wide, and you want to print it at 300 PPI:

  1. Calculation: 1000 pixels / 300 PPI * 2.54 = 8.47 cm
  2. Result: The image will be approximately 8.47 cm wide when printed.
