Description

Filters the default array of embed dimensions.

The width defaults to the content width as specified by the theme. If the theme does not specify a content width, then 500px is used. The default height is 1.5 times the width, or 1000px, whichever is smaller.

The 'embed_defaults' filter can be used to adjust either of these values.

<?php add_filter( 'embed_defaults', 'filter_function_name' ) ?>

Parameters

$width

(int) (required) Width of the embed in pixels.

Default: None

$height

(int) (required) Height of the embed in pixels.

Default: None

$url

(string) (required) The URL that should be embedded.

Default: None

Examples

Added to your child themes functions.php file, you can modify the default embed dimensions.

add_filter( 'embed_defaults', 'modify_embed_defaults' );
function modify_embed_defaults() {
    return array(
        'width'  => 750, 
        'height' => 375
    );
}
