Gravatar Size Via Theme Functions?

Question

Currently, to call comments I am simply using:

<?php wp_list_comments(); ?>

in comments.php. This is calling up gravatars, which I would like to be able to set the size of. How can I set the size of gravatars in my comments.

Answer 1

Quite simple, actually:

wp_list_comments( 'avatar_size=80' );

Just change avatar_size=80 to whatever is appropriate.

Here's a bit more information on customizing Gravatars in WordPress.
