WordPress is a popular website platform. It uses Gravatar for profile pictures. Gravatar stands for “Globally Recognized Avatar”. When you comment on a blog, it shows your Gravatar. Sometimes, you may want to change the Gravatar image size. This guide will help you do that easily.
What is a Gravatar?
A Gravatar is a small image. It represents you online. It appears next to your name on blogs, forums, and other sites. WordPress uses Gravatars by default. If you have a WordPress site, you might want to change the Gravatar size. This can make your site look better.
Default Gravatar Image Size in WordPress
The default Gravatar size in WordPress is 96 pixels. This size works for most websites. But, you might want a different size. Maybe a smaller or larger Gravatar. Changing the size is simple. You just need to follow a few steps.
Steps to Change the Default Gravatar Image Size
Changing the Gravatar image size is easy. Follow these steps:
1. Access Your WordPress Dashboard
First, log in to your WordPress site. Go to your dashboard. This is where you manage your site.
2. Go To The Theme Editor
In the dashboard, find the “Appearance” menu. Click on it. Then, click on “Theme Editor”. This will take you to the code editor.
3. Find The Functions File
In the Theme Editor, find the “functions.php” file. This file contains important code. It controls many features of your site.

function custom_gravatar_size($avatar, $id_or_email, $size, $default, $alt) {
$custom_size = 150; // Change this number to your desired size
$avatar = get_avatar($id_or_email, $custom_size, $default, $alt);
return $avatar;
}
add_filter('get_avatar', 'custom_gravatar_size', 10, 5);
