Reading Time WP let’s you easily add an estimated reading time to your WordPress posts. Activating the plugin will automatically add the reading time to the beginning of your post’s content. This can be deactivated in the Reading Time settings which can be accessed from your Dashboard’s Settings menu. You can also edit the label and postfix from this menu.
If you’d prefer more control over where you add your reading time you can use the [rt_reading_time] shortcode to insert the time into a post. This shortcode also excepts values for label and postfix. These are optional. Ex. [rt_reading_time label="Reading Time:" postfix="minutes"] .
The reading time is based on 300 words per minute which is the average adult reading speed based on this Forbes article from 2012. If you would like to change to a different value you may do so from the Reading Time settings menu in the Dashboard’s Settings menu. The plugin automatically rounds up to the nearest minute.
You can also use WordPress’ do_shortcode function within your theme template.
