The default excerpt length of WordPress is 55 words. Some one like me may want to change the excerpt length.

I like the have a smaller excerpt length for the homepage. WordPress provides a interface for changing the default excerpt length. The method is very simple and easy.

Put these codes into the function.php file in the theme directory. I prefer 35 in my blog. It can be changed to any number you like. Or this value can be stored in the options table.

The code:

// excerpt length
function option_excerpt_length($text){
  return 35;
}

add_filter('excerpt_length', 'option_excerpt_length');
