Analogy behind Excerpt Length of Teaser

One thing I like about customizing WordPress, is its filter feature, with which you can override any default function of WordPress. So, analogy behind adjusting excerpt length is too using WordPress filter and overriding it with another filter with new parameters.

Change Excerpt Length in Thesis Theme

To change excerpt length on homepage, add the below code in custom_functions.php in Thesis Theme.

NOTE: Make sure you take full backup of custom_functions.php file using FTP before modifying it or you can also refer to the article about how to safely edit custom_functions.php

// Teaser Length
function teaser_length($length) {
 return 70;
}
add_filter('excerpt_length', 'teaser_length');

Once you have added above code in custom functions, refresh the website homepage and look for the teaser length. If it doesn’t satisfy you, simply adjust value on line number 3 of above code depending on your need.
