How to Set oEmbed Max Width in WordPress 3.5 with $content_width

function.php file :

add_filter(‘embed_defaults’,’yourthemename_embed_defaults’);
function yourthemename_embed_defaults($defaults) {
$defaults[‘width’]=600; // or whatever you want
$defaults[‘height’]=360; // or whatever you want
return $defaults;
}

Thanks for writing.

I’m not sure of what’s the intention of that tutorial. I can tell that the $content_width variable is already defined in the theme (includes/options.php)

Also, the dimensions of the embed are usually set within the embed code. However, for example, for our theme’s blog posts embed code, the video is stretched to take the full width of its section.

Best,
Juan.
