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 = 22933 x 28863 = 661,915,179 pixels
  • Pixel count = 662 million pixels
  • Resolution = 662 mega pixels
  • A full frame sensor would be 19 x 24 mm (0.79)
  • Pixel density would be 637 pixels/mm or 16180 pixels/inch (dpi)
  • Pixel pitch: 1.6 micron (exceptionally 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.
