odd image resizing of posts featured images on homepage

Check your Media Settings. My guess is, that the Medium size, which is used for the post list, is not sufficient.

Take https://www.bojansokolovic.com/wp-content/uploads/2014/12/Subotica-Wedding-Photography.jpg for example: It has 300x449px. Your maximum height in the settings seems to be 300px. Thus, the medium image gets resized to 200x300px, which is too small and results in upscaling.

In fact, the width of the image can be as large as 432px in one-column-mode. Applied to that example image, the original file would have to be at least 432x647px, and the medium settings must be equal or larger than both of these values. If you want to use even higher thumbnails, the settings would have to be changed accordingly. Try 432×650 or 432x700px.

Keep in mind that this has impact on loading speed of your website. Lowering the number of posts per page to 8 might help here, if you experience long loading times.

thanks very much!

Sorry, I forgot to mention this: There’s a plugin that might help you after changing the media settings – https://www.ads-software.com/plugins/regenerate-thumbnails/
