Fix Image Elements do not have explicit width and height

Here we are going to fix the image dimension that occurs over different parts of the generatepress theme like in the logo section, in related posts, while setting up widgets in the sidebar, etc.

Image elements do not have explicit width and height

If you are using JPG or PNG logo then you have to set width and height using CSS code in GeneratePress Theme.

Go to Appearance > Customize > Additional CSS and add the following code.

img.header-image.is-logo-image {
	height: 65px;
	width: 160px;

If you are using SVG Logo then you have to specify width and height using Code Snippets i.e. you need to add a code in functions.php.

You can use the Code Snippets plugin or you can directly paste the code into the child theme’s functions.php.

add_filter('generate_logo_attributes', function($output){
	$add_attr = array(
				'width' => '160px',
				'height'   => '65px',
	$new_output = array_merge($output,$add_attr);
	return $new_output;

  2. Hello.

    Thank you very much. Very usefull post. I also use a plugin that add dimensions to all the images.

    By the way, do you know how to fix “Preload Largest Contentful Paint image” problem ? Generate Press is the first WordPress theme that have this problem. Never seen it before with other themes.

  3. Thank You, Dear!! Can you tell me about something “How to Reduce CLS issues, as show in the Page Speed Insights”

  4. Thank you for such an informative article. I am in Astra Free (Child) and Elementor Pro facing the exact issue. WP-Rocket excludes rectifying missing width and height attributes to SVG images. And, I really don’t want to use a plugin. Will the same filter you suggested to add to functions.php work for Astra Theme?

  5. img.header-image.is-logo-image {
    height: 65px;
    width: 160px;

    Is this CSS code applicable for other themes like Asona?
    If I try it once to check whether it’s working or not, will it break the theme?

    • Hi Subodh,
      It may not work since the CSS classes is/may be different, Use Inspect Elements feature available in your browser and fix it.

  6. Hi,
    even after adding your code for my svg logo, lighthouse (mobile) is still saying there is no W & H. any idea? thanks

    • Hi Manish,
      I think you are using wrong code or settings in the code may be different than desired one.
      Please check it and try again.
