How Do I Change the Size of a Featured Image in WordPress?

When you publish a post, the featured image is automatically set to the largest size that will fit on your blog post. If you want to change the size of the featured image, you can do so by editing the post’s header and footer. To do so, open the post’s header (found in the left column of your blog’s front-end) and click on the “edit” link next to the featured image. Then, in the “header options” section, change the size of the image by selecting a new size from the drop-down menu.

Finally, click on the “save changes” button to apply them to your post. The same steps can be used to change the size of the footer’s featured image.
