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 = 852 x 480 = 0.41 megapixels
  • Aspect ratio = 1.78
  • Angle of diagonal = 0.513 rad = 29.4°
  • Length of diagonal = 978 pixels
  • Letterboxing

    How does a 1.78 image fit on a screen with a different aspect ratio?
