Add Gravatar Support to Your WordPress Comments

Last Updated on by

After a few different people requested Gravatar support in the comments for the popular Choice WordPress theme, I decided to look into it more carefully. I came across this great post by HackWordPress which gives you a small code snippet to add Gravatars to your comments loop. Since then, I’ve been adding Gravatar support to all the themes here, just because it’s so simple to do. In this guide I’ll show you how exactly I integrate Gravatars into themes.

Before you continue, please understand this is guide is written for WordPress 2.5 and above only. The code gone over will not work in previous versions.

The Gravatar Code

Just plopping in the following code in your comments loop will work, but it probably won’t look very good as-is.
<?php if(function_exists('get_avatar')) { echo get_avatar($comment, '50'); } ?>

Basically this code will check to see if you have the get_avatar (native to WordPress 2.5), then display the avatar of the commenter in a 50px square.

Use a Ruler

If you want to make sure your Gravatars are at a suitable size, I recommend the MeasureIt Firefox extension. This will help you measure out an area in your theme to determine a good size for Gravatars.

Where to put the code?

In the Choice theme, I found that 40 was a good size. So where did I put this code exactly?

Choice Gravatar Location

Anywhere within the foreach and endforeach (the comments loop) will work.

Styling your Gravatars

Once you have Gravatars displayed on your comments template, you’ll probably want to style them too. You’ll notice the Gravatar code spits out the “avatar” class on each image. Let’s add a line to the CSS stylesheet to float this to the left, and add a small right margin.

img.avatar {float:left; margin-right:5px;}

There you go, you have nice looking, perfectly sized, styled Gravatars. Of course themes will differ, you can style them however you like.


Remember, this code will only work on WordPress 2.5 and above. The function_exists conditional tag will cause your theme not to break, but nothing will show up in previous versions. More information on other methods of using Gravatars are detailed on the WordPress Codex.

If you just read this whole article and have no clue what a Gravatar is, I suggest you read this one first by Lorelle on WordPress. It goes over the basics of how to get your own Gravatar by signing up at as well as using Gravatars on older versions of WordPress with plugins.

Not only can Gravatars be used for comments, but they can also be added to author’s individual posts as well.

    I’m a huge supporter of Gravatars, so I love seeing more theme designers add built-in Gravatar support.

    Like you said, it really is that easy to do!

    This might be kind of anal, but those who are copying and pasting code that you have posted, could you add the background:#fff; to your within your css? If you try highlighting the code the way that it is now, it’s hard to tell what you’re highlighting because you haven’t declared a background on it. Anyways, it might make things easier for your users…


  • Leland

    @Spencer: You know…that’s actually been bothering me for the longest time and I had no idea what the problem was. I just added the background CSS to the .post class and .head class. Thanks for the tip.

    @eTomyam: Hmm…is this a Gravatar issue or a styling issue?

    Thanks for the comments everyone, glad you all liked the tutorial.

  • Prashant

    Thank for the help. I made some changes to my site the other day, and noticed…where the heck are my gravatars? Had to figure out how to put back on. The best help was including the css info.

    i have installer the gravatar and it is functioning well on my comment page..but how do i show the avatar on my recent comments on the sidebar?

  • Leland

    @testercraft: I found this plugin that may be what you’re looking for: Gravatar Recent Comment

  • Thin king man

    That was super helpful, bro. I’ve spent the last two days trying to figure this out. WordPress couldn’t answer my question; neither could Gravatar. But you did. Thank you.

  • Raymond Burton

    Sweet! I’ve been hacking away at a theme for a long time and this was the finishing touch. Thank you so much!

  • Andrew Miller

    Thanks for the tips. The Gravatar site didn’t explain it clearly enough, but your screenshot made it clear. Cheers.

    The code works to get the avatars in the comments. I’m having trouble with alignment in IE7.

    In IE7, the first avatar aligns correctly, then avatars in subsequent comments are indented to the right by a couple of pixels.

  • TAG

    I am so glad I found your site. Great information on how to get to add a Gravatar to ones site. I wasted hours trying to play with a plugin and it took me just seconds following your examples to get what I wanted for the site.

    Thank you so much! I only wished I had googled you earlier :-)

  • Jenny

    great!! glad i found this. now to find a way to reset my comments so they all have gravatars next to them.

    Thanks a lot! This was easy :)

  • Steve Portigal

    Thanks, I’ve just set it up on my blog, too.

  • Twinkling82

    Oh my god, at last a code, that worked… I couldn’t get the system to load the avatars, that were attached to the author emails… you’rs worked!!

    Many many thanks.

  • Hairtransplantdoc

    My theme doesn’t contain this loop inside comments.php, any ideas?

  • Twinkling82

    Your theme should contain avatar, as it’s quite standard in wordpress. If it doesn’t it’s a craooy theme, and you would be better off finding another theme. ;)

  • Heather

    Thank you so much – worked like a charm!

  • Sandra Hendricks

    It worked like a charm! Thank you soooo much Leland for your post! Your Blog is truly a blessing to all who have WordPress! :)

  • Apostolos

    Thanks for this great how-to mate! Works just fine! Whoop whoop!

  • Sasha

    Thanks, I am having some real issues getting this to work on my blog, but hopefully this will help. I am using a theme that runs on Thematic so I can find the “foreach” you mentioned but not the “endforeach” and when I added the code it didn’t work for me. I guess I will keep at!

  • Bruce

    Wow! That helps. I been fooling around with my non premium theme for hours trying to figure that out. WordPress Codex support doesn’t help much. They don’t explain exactly where to put the code. What a relief that I found this site. Been coding since 2008 and still run into problems.

  • Nico

    Thaaaaaaaaaaaaaank you!!!! :-)
