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 = 792 x 1224 = 0.97 megapixels
  • Aspect ratio = 0.65
  • Angle of diagonal = 0.996 rad = 57.1°
  • Length of diagonal = 1458 pixels
  • Letterboxing

    How does a 0.65 image fit on a screen with a different aspect ratio?
