But it does mean the Summary will occupy more space.
Square images of all the same size are the best way to go.
Some tips on setting the right sizes.
1. Your single product content width is: 1050px ( minus container padding ).
2. Product Image Area Width is 50%.
3. Max image width required is therefore 525px.
4. If you want the hover zoom / lightbox to show a larger image eg. x2 zoom. Then you could upload your original image as 1050px. And set your Product Image size in Customizer > Woocomerce to 525px.
