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 = 10380 x 7816 = 81,130,080 pixels
  • Pixel count = 81.13MP pixels
  • Resolution = 81.13MP pixels
  • A full frame sensor would be 31.9 x 24 mm (1.33)
  • Pixel density would be 288 pixels/mm or 7320 pixels/inch (dpi)
  • Pixel pitch: 3.5 micron (exceptionally fine)

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.
