apply_filters( 'admin_post_thumbnail_size', string|array $size, int $thumbnail_id, WP_Post $post )

Filters the size used to display the post thumbnail image in the ‘Featured Image’ meta box.


Description

Note: When a theme adds ‘post-thumbnail’ support, a special ‘post-thumbnail’ image size is registered, which differs from the ‘thumbnail’ image size managed via the Settings > Media screen. See the $size parameter description for more information on default values.


Parameters

$size

Post thumbnail image size to display in the meta box. Accepts any valid image size, or an array of width and height values in pixels (in that order). If the 'post-thumbnail' size is set, default is 'post-thumbnail'. Otherwise, default is an array with 266 as both the height and width values.

$thumbnail_id

Post thumbnail attachment ID.

$post

The post object associated with the thumbnail.
