Optimal image size for Posts

Dear support team,

I have been a lot of experiments with images today, but I did not find a satisfying solution for me. I know that wordpress compresses and crops images for different purposes. Regarding shapely posts: Is there something like an optimal file size for the featured post images? Or maybe an optimal width / height ratio?

Best regards and thanks in advance


These are the images sizes we used for shapely.

For full featured image 1110530
For featured image 730
For featured image in grid layout 350*300

I suggest you to upload the good quality image of yours, and allow WordPress to take care of the resizing, it will do its best. But if you still want to upload the right size image, then you can upload like the above sizes.
