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 = 206400 x 15520 = 3,203,328,000 pixels
  • Pixel count = 3.2 billion pixels
  • Resolution = 3.2 giga pixels
  • A full frame sensor would be 319.2 x 24 mm (13.3)
  • Pixel density would be 5733 pixels/mm or 145630 pixels/inch (dpi)
  • Pixel pitch: 0.2 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.
