Let be the golden ratio, and let be a face ratio. Then . A natural idea is to have a linear function that maps the difference to [0, 10] such that the difference 0 is mapped to 10. However, one has to select what value is mapped to 0, i.e., which face ratio is absolutely ugly. For example, one can decide that the ratio 3 is absolutely ugly, so is mapped into 0. The function that maps into [10, 0] is , so the measure of beauty for a face ratio is . Good news: for your values, the measures are both around 9.97; this is because they are very far from the ugliness standard.
