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 = 2481 x 3507 = 8,700,867 pixels
  • Pixel count = 8.7 million pixels
  • Resolution = 8.7 mega pixels
  • A full frame sensor would be 17 x 24 mm (0.71)
  • Pixel density would be 69 pixels/mm or 1750 pixels/inch (dpi)
  • Pixel pitch: 14.5 micron (rather large)

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.
