Instructions:

  1. Enter the aspect ratio. This might be listed as two numbers, such as "16:9". In this case, 16 is the aspect width, and 9 is the aspect height. Or, if the aspect ratio is a decimal number, such as 1.77, enter that in the aspect ratio field.

    Also, you can click on one of the blue buttons, which are all common aspect ratios.

  2. Enter the diagonal screen size in inches. The vertical and and horizontal screen size will be displayed.>

    Also, you can click on one of the green buttons, which are all common monitor and TV sizes.

    The height will appear to the left of the green square, and the width will appear above it. Be sure to add about an inch to both of these dimensions to account for the size of the bezel.
