Cm to Pixels FAQ
Everything you need to know about converting physical measurements to digital pixels, understanding resolution, and mastering the math behind DPI and PPI.
To convert centimeters to pixels, you first convert centimeters to inches by dividing by 2.54, and then multiply by the resolution (DPI/PPI). The formula is: Pixels = (cm / 2.54) × DPI.
DPI stands for Dots Per Inch, and PPI stands for Pixels Per Inch. They both refer to the resolution or density of pixels/dots in a given physical space. Higher values mean more pixels are packed into an inch, resulting in sharper, more detailed images.
The standard resolution for screens and web design has traditionally been 96 DPI (or PPI). However, with the rise of high-density ‘Retina’ displays, modern screens often have physical pixel densities of 150 to 300+ PPI, though CSS pixels still generally map to the 96 DPI standard.
For high-quality photo printing, a resolution of 300 DPI is the industry standard. This ensures the printed image is sharp and free of pixelation. For large format prints like banners, 150 DPI or lower is often acceptable since they are viewed from a distance.
At 96 DPI, there are approximately 37.8 pixels in a centimeter. This is calculated by dividing 96 by 2.54 (the number of centimeters in an inch).
While often used interchangeably, they are technically different. PPI (Pixels Per Inch) refers to the pixel density of digital screens and image files. DPI (Dots Per Inch) refers to the physical dot density of printed materials. However, in digital design software, the terms are frequently used to mean the same thing.
