I'm inserting an image in my theme as follows:

the_post_thumbnail('large');

Which results in the following HTML:

<img class="wp-post-image" width="660" height="440" sizes="(max-width: 660px) 100vw, 660px" srcset="/uploads/IMG-1024x683.jpg 1024w, /uploads/IMG-300x200.jpg 300w, /uploads/IMG-768x512.jpg 768w, /uploads/IMG-254x169.jpg 254w, /uploads/IMG-578x385.jpg 578w, /uploads/IMG-665x443.jpg 665w, /uploads/IMG-1600x1067.jpg 1600w" src="/uploads/IMG-1024x683.jpg">

Notice width="660" height="440" and sizes="(max-width: 660px) 100vw, 660px" which doesn't correlate with the size defined for large in Media Settings > Image sizes which is supposed to be 1024 x 1024.

What am I doing wrong?

WordPress uses min( intval($content_width), $max_width ) inside image_constrain_size_for_editor for large image size.

As I can see your $content_width is set to 660. So, change the $content_width in your functions.php file to the 1024 or whatever you need. For full-width layout, it's better to remove it.

Example: $GLOBALS['content_width'] = 1600. That's it.

If you don't know what content_width is, see Content Width for more info.

You're doing right. Just miss one step. I guess you upload image before change the size of large in setting. Final step is Regenerated thumbnail. Just install the plugin with same name, go to Tool > Regenerate thumbnail and click. ;)

  • I did not change the setting for 'large' at all. 1024 is the default for 'large'.

  • If it's not work. Scan your code for the function that adjusted thumbnail size. Like: add_image_size or set_post_thumbnail_size

try this way 

$image = wp_get_attachment_image_src(get_post_thumbnail_id(get_the_ID()), 'large', false);


<img src="<?php echo esc_url($image[0]);?>" alt="">
