Aspect Ratio Calculator

Aspect Ratio is the ratio of the width against the height of a rectangle.

This is expressed as either the simplest values (e.g. 4:3) or as the width value against 1 (e.g. 1.33:1)

Television and computer screens are also described by the diagonal size of the screen

This calculator includes all these dimensions.

Calculations can be saved to a table by clicking the "Add to table" button

(The table appears the first time the button is clicked)

There is also the option to create a PDF document
