Question

I need help finding where and how to change the size and crop of a featured image within a post. I’ve looked in functions.php and init.php, but with no success. I’m using a child theme of the inLine theme.

The current height is set for 130px.

I’ve tried changing the css, but that only stretches the image.

Answer 1

In your functions.php, paste one of these and adjust pixel width and height to your liking:

set_post_thumbnail_size( 100, 100 ); // 100 pixels wide by 100 pixels tall, box resize mode

OR:

set_post_thumbnail_size( 100, 100, true ); // 100 pixels wide by 100 pixels tall, hard crop mode
