How to adjust featured image size in post?

Hello altious,

Please keep in mind that the algorithm to cropping of featured images is already defined and if you want to change this structure, please notice that you will damage the theme layout. Notice that each module/block has a special size of featured image as you can see in our documentation here -> https://forum.tagdiv.com/featured-image/ and here -> https://forum.tagdiv.com/theme-thumbs/
If you want to make some changes and adjustments to your theme, please notice that is not a simple task and you should make all of these for the entire website to bring best results. So, if you are not aware of the steps which are needed to take in this regard, please consider hiring a freelancer/developer to help you because we cannot provide custom work at the moment, sorry!

Thanks for your understanding!
