   I already display a number of posts on the homepage that is different from that chosen under settings >> reading.

   I was wondering if it's possible to display a number of comments on a particular custom page template that is different than the number chosen under settings >> discussion.

   This is what I use for the posts:

   <?php query_posts($query_string . '&showposts=28'); ?>

   What would be the equivalent of this for comments?

   Sure, it's in the Docs (top right), but to save you the clicks..
   http://codex.wordpress.org/Template_Tags/wp_list_comments

   comments.php of your theme, add the per_page parameter to ..
   

   wp_list_comments();

   If that function has parameters inside it already, then consult the page above on stringing parameters together.. (just see the examples basically).

   You'd proberly need some conditional tags around it if you want to do it on a per page basis...
   http://codex.wordpress.org/Conditional_Tags

   A very basic example could be..
   

   if(is_page('somepagenameORid')) {
   wp_list_comments( 'per_page=5' );
   }
   else {
   wp_list_comments( 'per_page=10' );
   }

   or (posts equivalent /ie. not a page)
   

   if(is_single('somepostnameORid')) {
   wp_list_comments( 'per_page=5' );
   }
   else {
   wp_list_comments( 'per_page=10' );
   }

   All I had to do was add the per_page=5 parameter within list comments and it worked. I didn't even know that could be done. I didn't have to use any conditional comments since I already use a separate comments.php file for that page anyway (it's kinda necessary for other reasons) Thanks a bunch t31os_ you saved the day once again!

   I think I celebrated a little too soon. Apparently using the per_page parameter introduces a little problem. After the comment is made instead of refreshing and showing the latest comments - no comments display at all. One has to manually press the refresh button to see the new and other comments. I tried it in the default theme and in different browsers and the same problem.

   the code:

   <?php wp_list_comments('per_page=30'); ?>

   Could the parameter be depreciated with the latest WP version?

   Just tested it, works here...

   I use a custom callback, so ignore the additional code in there, but this is my test code from that line..
   

   <?php wp_list_comments('callback=whatsaid&type=comment&per_page=1'); ?>

   Viewed a post that has 5 comments (it's my test install), and i see 1 comment, and 4 more pages, which i can then click through.. (1 per page as my code above).

   Posted a new comment, and it sticks me back onto page 1 but i can see the comment straight away, no refreshing required..

   NOTE: Also tested with it set to 3, just to try an alternate value, results are as expected.

   If you can suggest something to replicate the problem i'll happily try it, but at this point it works as i'd expect it to...

   No, it still doesn't work for me. My usual theme (red carpet) also uses a custom callback. Before I was using this:

   <?php wp_list_comments('per_page=5&callback=custom_comments&type=comment'); ?>

   and like I said, no comments showed after submission.

   I then changed the per_page to the end like your code:

   <?php wp_list_comments('callback=custom_comments&type=comment&per_page=5'); ?>

   and this time comments did display but instead of being shown the last comment I am taken to page 2. How weird is that??? It doesn't matter how much I change the per_page value to - it always takes me to page 2.

   The problem can't be in my comments.php file since I also tried it in an untouched default theme. So it's most likely due to a plugin conflict. The only comments related plugin I use is wp-commentnavi and deactivating that doesn't make a difference. I'm not going to deactivate all my plugins since that will erase the settings of a lot of them (and I need each and everyone of those anyway).

   I will try to troubleshoot some more, if I can get it to work I'll post it here, otherwise I'll just have to do without I suppose.

   Thanks for trying t.

   Ok, to make some comparisons, how do you have your comment options set? Maybe the problem is related to the chosen settings (just an idea).

   Admin > Settings > Discussion.

   Maybe worth playing around with the settings and see if the problem remains.
