How to Change the Gravatar Image Size in WordPress

There are two ways to change the Gravatar image size in WordPress:

Using the WordPress Customizer

1. Go to Appearance > Customize.
2. In the left sidebar, select Comment.
3. In the right sidebar, under Gravatars, you will see a field for Image Size. Enter the desired size in pixels.
4. Click Publish to save your changes.

Using FTP

1. Connect to your WordPress site using FTP.
2. Navigate to the following directory:
   • wp-content/themes/[your-theme-name]/
3. Open the comments.php file in a text editor.
4. Find the following line of code:

PHP

$avatar_size = 96;

Use code with caution. 

5. Change the value of 96 to the desired size in pixels.
6. Save the comments.php file and upload it back to your WordPress site.

The new Gravatar image size will now be used for all comments on your site.

Note: The maximum Gravatar image size is 512px by 512px. If you set the image size to a larger value, the Gravatar may appear blurry.

Additional tips:

• You can also change the Gravatar image size for specific user roles. To do this, you will need to edit the user-role.php file in your theme.
• If you are using a child theme, you can create a custom comments.php file and override the default settings.
• You can also use a WordPress plugin to change the Gravatar image size. There are many plugins available, so you can choose one that best suits your needs.
