Change Vimeo/Youtube default size in Wordpress

Question

How to change Vimeo/Youtube embed sizes?

Currently the default embed is very small 300x150, i need 540px minimum :(

Using snippet to filter in functions.php, the code no works.

function rezzz_embed_defaults($defaults) {
    $defaults['width'] = 350;
    $defaults['height'] = 200;

    return $defaults;
}

add_filter('embed_defaults','rezzz_embed_defaults');

Please see screenshot -> https://i.sstatic.net/gweev.png

Please see your code carefully. I have used your code but changed width and height.

function rezzz_embed_defaults($defaults) {
    $defaults['width'] = 540;
    $defaults['height'] = 304;

    return $defaults;
}

add_filter('embed_defaults','rezzz_embed_defaults');

You need to provide width and height in proper ratio to use video from youtube, vimeo and other source.

You can see working demo of above code here
