Is there a standard featured image size that Wordpress works best with? Or is the featured image sizing based on theme settings or requirements?
WordPress has a few default sizes:
- Thumbnail ( Defaults to 150x150 )
- Medium ( Defaults to 300x300 )
- Large ( Defaults to 1024x1024 )
- Full ( Defaults to Original Image Size )
Of course, these can all be changed by visiting the
Settings -> Media page in the Admin Panel of your installation. That being said, most the time Themes have their own sizes set for things such as Featured Images. You may want to either contact the theme author via the WordPress support forums, which each theme has their own set of forums, or if it's a premium theme you should contact their support.
If none of these works just upload a featured image and copy the size that the theme generates, that will always give you your width and height needed.
The default Feature image size in wordpress is 768px width (is a hiden image size that use to be use by themes)
The limitations of the image size are your theme (you must not have a different image size as the frame of your image in the post).
But if you are a developer and you would like to modify the image size. Those are the recomendations in articles if you would like to be featured in google.
- non-AMP webpages: google require a minimum of 696px wide
- AMP webpages: 1200px wide.
