Although users can change the font size of a web page through standard browser settings,
few people knows or remembers how to do it.

WP-chgFontSize is a WordPress plugin that allows users to change dynamically the font size by adding
a text or image selection on your blog. It also stores the user selection on a user’s browser cookie.

It can be used as a widget or directly as a PHP call in the theme.


  • Font Size Options Panel
  • Widget activation


  1. Download WP-chgFontSize.
  2. Decompress and upload the contents of the archive into /wp-content/plugins/.
  3. Activate the plugin on your WP Admin > Plugins page by clicking ‘Activate’ at the end of the ‘WP-chgFontSize’ row.
  4. Configure the plugin on your WP Admin > Options > Font Size page.
  5. To use it, there are two possibilities:

* If your theme supports widgets, and you have installed the widget plugin or you are using WordPress 2.2 or higher, add the ‘WP-chgFontSize’ widget on your WP Admin > Presentation > Widgets page.
* Add <?php chgfontsize_display_options(); ?> at the place in the theme’s file where you want the font size selection appear.
