How to calculate aspect ratio?

  1. Take your original height. In our example, it will be 1200 pixs.
  2. Take your original width.
  3. Divide the height by the width, e.g. 1200 / 1600 = 0.75.
  4. Multiply the quotient by the preferred width, e.g. 0.75 * 300 = 225.
  5. The resulting figure is your new height given in pixels.
