Megapixel calculator

A "megapixel" is one million (1.000.000) pixels. Enter the pixel dimensions of your photo, camera, screen or tv, and calculate how many megapixels that is.

Calculate megapixels

  • Size = 6272 x 3524 = 22,102,528 pixels
  • Pixel count = 22.1MP pixels
  • Resolution = 22.1MP pixels
  • A full frame sensor would be 42.7 x 24 mm (1.78)
  • Pixel density would be 174 pixels/mm or 4430 pixels/inch (dpi)
  • Pixel pitch: 5.7 micron (very fine)

Background

For decades, advances in camera technology have been measured in 'megapixels', although more pixels doesn't always mean better quality. The same metric can also be used to describe the resolution of photos, or digital screens. This megapixel calculator brings it all together. Calculate, compare, visualise and estimate.
