    For example if an uploaded image is 1000 x 500 pixels.

    And the customer chooses a print width of 10 inches, could the height field be auto calculated at 5 inches?

    Thanks

    It is possible to achieve that using conditional logic to update a form field value.

    Or you can set condition like this if you want that height is always half less then width.
