NTSC TV: 0.35 megapixel

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 = 720 x 486 = 349,920 pixels
  • Pixel count = 349.92KP pixels
  • Resolution = 349.92KP pixels
  • A full frame sensor would be 35.5 x 24 mm (1.48)
  • Pixel density would be 20 pixels/mm or 510 pixels/inch (dpi)
  • Pixel pitch: 50 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.
