How to Convert PX to CM

One inch is 2.54 cm, so:
cm = px × 2.54 ÷ DPI

At 96 DPI that is cm = px × 0.026458: 60 px × 2.54 ÷ 96 = 1.588 cm. At 300 DPI, 60 px is only 0.508 cm.

Which DPI Should You Use?

  • 96 DPI — websites and CSS. Browsers treat 1 inch as 96 CSS pixels on every device, so this gives the size in your stylesheet.
  • 150 DPI — drafts and office printing. Fine for documents that are read rather than inspected closely.
  • 300 DPI — print quality. The standard for photos, ID pictures, posters and anything printed professionally.

The centimeter on paper never changes — only how many pixels you need to fill it. More DPI means more pixels for the same physical size, and a sharper print.
