Featured image alignment

Hi there,

Featured images on all blog post pages are aligning to left. Just wondering if there is a way to align them with heading.

Here is the link for screenshot :- https://drive.google.com/file/d/1muODUHuolefwn1QHqgmRnGIpMOQYiYcl/view?usp=sharing

Would prefer if I can set the size/pixels for all featured images on posts’ pages.

Thanks
