Aspect ratio calculator

Enter width and height

Aspect Ratio (short: A/R) is the width of an image or screen, divided by the height. In landscape orientation, the A/R is > 1, for portrait orientation the A/R is < 1 and for square screens, this is = 1.

Calculation

  • Size = 2400 x 3000 = 7.2 megapixels
  • Aspect ratio = 0.8
  • Angle of diagonal = 0.896 rad = 51.3°
  • Length of diagonal = 3842 pixels
