Understanding the WordPress Template Hierarchy: A Guide for Designers

Hey there, fellow designers! Welcome to my blog, where we dive deep into the world of WordPress and explore all its hidden gems. In today’s post, we’re going to unravel the mysteries of the WordPress Template Hierarchy. If you’ve ever found yourself scratching your head trying to understand how WordPress decides which template to use for a specific page, then this guide is for you. So grab a cup of coffee, sit back, and let’s embark on this enlightening journey together.

What is the WordPress Template Hierarchy?

Before we delve into the nitty-gritty details, let’s first understand the concept of the WordPress Template Hierarchy. Simply put, it’s a system that WordPress follows to determine which template file to load for a particular page on your website. This hierarchy is based on the type of content being displayed and the way WordPress organizes its template files.

The Core Template Files

To comprehend the WordPress Template Hierarchy, we must familiarize ourselves with the core template files that serve as the foundation for your website’s design. Here’s a list of the most essential template files you’ll encounter:

  1. index.php: This is the most generic template file in the hierarchy. It serves as a fallback for any page that doesn’t have a specific template file associated with it.
  2. style.css: Although not a template file per se, the style.css file is crucial for defining the overall look and feel of your website. It contains the CSS code that controls the visual aspects of your site.
  3. header.php: As the name suggests, this file is responsible for rendering the header section of your website, which typically includes the logo, navigation menu, and other elements that appear at the top of each page.
  4. footer.php: Similarly, the footer.php file handles the rendering of the footer section, which usually contains copyright information, social media links, and other elements displayed at the bottom of each page.
  5. sidebar.php: If you want to include a sidebar on your website, the sidebar.php file comes into play. It contains the code for the sidebar, where you can place widgets, advertisements, or any other additional content.
  6. single.php: This template file is utilized when displaying a single blog post or a single custom post type. It allows you to customize the layout and design of individual posts.
  7. page.php: When a user visits a static page on your site, the page.php file is used to render the content. This template file gives you control over the appearance of static pages, such as your About page or Contact page.

Understanding the Hierarchy

Now that we have a basic understanding of the core template files, let’s dig deeper into the WordPress Template Hierarchy. The hierarchy consists of a series of template files, each with a specific naming convention, which WordPress searches for in a specific order. It starts with the most specific template file and falls back to more generic ones if a specific file is not found.

To make things easier to grasp, here’s a simplified version of the WordPress Template Hierarchy:

  1. single-{post_type}-{slug}.php: This template is used for displaying a specific post or custom post type, identified by its slug. If you have a post with the slug "hello-world," the template file would be single-post-hello-world.php.
  2. single-{post_type}.php: If a specific slug-based template is not found, WordPress looks for a template file named single-{post_type}.php. This template is used for displaying posts of a particular post type.
  3. single.php: If there is no specific post type template, WordPress falls back to the single.php file. This template is used to display individual posts in a generic manner.
  4. page-{slug}.php: When a static page is being requested, WordPress searches for a template file with the page’s slug. For example, if you have a page with the slug "about-us," the template file would be page-about-us.php.
  5. page-{id}.php: If a slug-specific template is not found, WordPress looks for a template file named page-{id}.php. This template is used for displaying a specific page, identified by its unique ID.
  6. page.php: If no specific page template is available, WordPress falls back to the page.php file. This template is used to display static pages in a generic manner.
  7. index.php: Finally, if no other template file is found, WordPress resorts to the index.php file, which serves as the ultimate fallback template for all pages on your website.

Customizing the Template Hierarchy

While WordPress provides a default template hierarchy that covers most scenarios, there are instances when you might want to customize it further. Fortunately, WordPress offers several techniques to modify the template hierarchy according to your specific needs. Let’s explore a few popular methods:

  1. Template Files within Theme: One straightforward approach is to create custom template files within your theme. By following the naming conventions mentioned earlier, you can create specific template files for different post types or pages. WordPress will automatically prioritize these custom templates over the default ones.
  2. Template Partials: Another way to enhance the template hierarchy is by utilizing template partials. These are smaller template files that can be included within other templates using the get_template_part() function. This method allows you to reuse code across multiple templates, maintaining consistency throughout your website.
  3. Template Hierarchy Filters: For more advanced customization, WordPress provides a range of filters that allow you to manipulate the template hierarchy. By utilizing filters such as template_include and single_template, you can dynamically assign template files based on specific conditions or criteria.
  4. Child Themes: If you want to make comprehensive changes to the template hierarchy, creating a child theme is a recommended approach. A child theme inherits the functionality and styling of its parent theme while allowing you to override specific template files without modifying the original theme. This method ensures that your changes won’t be lost when the parent theme is updated.


  1. Q: Can I have multiple template files for a single post type?
    A: Absolutely! WordPress allows you to create multiple template files for a single post type by utilizing the naming conventions mentioned earlier. This flexibility enables you to have different layouts and designs for specific posts or groups of posts within the same post type.

  2. Q: What happens if I don’t have a specific template file for a page?
    A: In such cases, WordPress will fall back to the next available template file in the hierarchy. If no specific or fallback template is found, it will finally resort to the index.php file. However, it’s always recommended to create custom templates for specific pages to have better control over their appearance.

  3. Q: Can I override template files from plugins?
    A: Yes, you can override plugin template files by creating a custom version of the file within your theme. Simply recreate the folder structure within your theme, place the modified template file there, and WordPress will prioritize it over the plugin’s default template.
