Crop thumbnail to exact dimensions on Wordpress for medium size

Question

In Wordpress Media Settings the Thumbnail size we can crop thumbnail to exact dimensions.

But for the Medium size no option to get exact dimensions. There have a way to force exact dimensions for medium size?

If yes, how to implement to the functions.php

Answer 1

Add this to your functions.php:

add_action( 'init', create_function( '', 'add_image_size( "cropped_medium", 300, 150, true );' ) );

The arguments are size name, width, height, and whether to force a crop.

Answer 2

If you want medium images to be cropped instead of scaled, like you can choose for the thumbnail size in the options page (but not for medium or large sizes), you can set the medium_crop option to true in your functions.php:

if(false === get_option("medium_crop")) {
    add_option("medium_crop", "1");
} else {
    update_option("medium_crop", "1");
}
