Change Your Avatar Size Using PHP

By default, WordPress displays avatar images at a relatively small size, which might not be ideal for every layout or design. It’s a personal choice, so if you’d like to increase the size of the avatar image to better suit your needs, i.e. bigger or smaller, you can use the snippet below. Simply replace the value 500 with the desired pixel size to adjust the avatar dimensions accordingly.

Code Snippet

add_filter( 'pre_get_avatar_data', function( $args ) {
	$args['size'] = '500';
	return $args;
}, 5 );

Where to Add This Code

Here are two easy options:

Option 1: Install WPCode Lite Plugin

This is by far the safest method and is beginner friendly if you’re not used to editing theme files.

1. Search for WPCode Lite plugin in your website dashboard.
2. Install the plugin.
3. Go to Snippets > Add New.
4. Give your snippet a name like “Change Your Avatar Size.”
5. Paste the code above.
6. Choose “Run snippet everywhere”.
7. Choose PHP, not CSS or any other.
8. Save and activate.

✅ Done! Your avatar is now the size you prefer.

Option 2: Functions.php

We don’t advise this option unless you’re a developer or if you feel comfortable editing theme files:

1. Open your functions.php file.
2. Paste the snippet at the bottom.
3. Save and upload if needed.

💡 Tip: Always use a child theme to avoid losing changes when your theme updates.

NOTE: We use WPCode Lite because it’s more flexible than others, there’s no need to upgrade to pro unless you’re a developer, it offers many free snippets, can choose where to run it, won’t publish if the code is wrong so won’t break your site, PHP is included compared to others you have to buy the their pro, and best of all the free version can easily be downloaded from your WordPress Repository.
