How to calculate aspect ratio? Take your original height. In our example, it will be 1200 pixs. Take your original width. Divide the height by the width, e.g. 1200 / 1600 = 0.75. Multiply the quotient by the preferred width, e.g. 0.75 * 300 = 225. The resulting figure is your new height given in pixels.
