In WordPress you can set individual templates for pages, which allows you to easily include additional functionality. Unfortunately this feature is not available for posts. Here is where this plugin comes.
After installtion you will be able to choose a template for each post the same way you do with pages.
You can find <a href="https://codex.wordpress.org/Pages#Creating_Your_Own_Page_Templates" rel="nofollow ugc">how to your own templates</a> in the Codex.

The same as page templates, but for posts.

WoWPth lets you create your theme and customize its structure in an easy and interactive way. It allows you to define your own layout.
You can customize width and height of the layout using sliders and add and delete partitions of divisions up to a level. 
Areas can also be resized in width and height by dragging the handles that separate the boxes; each area is widget enabled.
It is also maintained the possibility to access the version 1.0 of the plugin in case you prefer a more traditional layout.
The generated themes also allow to edit the image header and the background of the theme and support WordPress widgets and custom menus.
WoWPth has been developed with WordPress version 3.3.0 and has been tested up to version 3.3.1 and backward
WoWPth has been verified fully functional with: 
* Internet Explorer: 7, 8. 
* Firefox: 3.6. 
* Chrome: 6, 7. 
* Safari: 5. 
* Opera: 10.
