What is a WordPress Theme and What Is It Used For

Are you wondering what is a WordPress theme? Then, we’ll answer your question here.

Simply, a theme is an outer layout that determines how your website looks. Here, we’re addressing the themes that are used particularly in WordPress, one of the best website building platforms

Similar to its general use, the theme in WordPress refers to a design layout that defines the overall appearance of a WordPress site. It controls how your site content appears online and also provides various functionalities to the site.

In this blog post, we’ve explained what a WordPress theme is, why it’s used, its importance, and everything you should know about themes. Let’s begin.

1. What is a WordPress Theme? (Definition)

A WordPress theme is an entire design frame that indicates how your WordPress site appears to the visitors. In other words, it’s the collection of style sheets that gives your website a shape, look, and feel.

A theme consists of the layouts, colors, font styling, position and size of elements, animations, transitions, and other styling details. And, all these entities of the theme can be customized according to the need.

Speaking of WordPress, it’s the most popular Content Management System (CMS) available on the market. CMS refers to a type of software or tool which lets you create, manage, and publish content online, easily without coding.

In simple terms, we can define WordPress as a user-friendly website creation software. It allows you to easily start a blog, a business site, an online store, or any other type of site.

Getting back to the WordPress theme, it’s something like skin and skeleton of a WordPress-based website that defines how content appears to the viewers.

It controls almost every aspect of a site’s visual presentation. That includes colors, fonts, header and footer options, navigation menu styles, and styling of every page on your site.

WordPress Themes vs WordPress Templates

When talking about themes, you may also see the word ‘templates’ being used frequently. Or you may find ‘theme’ and ‘template’ used interchangeably for one another. 

On the web, people generally use ‘template’ and ‘theme’ as synonyms. But in WordPress terminology, they’re slightly different. A template denotes a page layout i.e. the positioning of elements on a page. Whereas a theme is a collection of these layouts with styling and some minimum functionality for a website.  

Technically, a template is an actual PHP file inside a theme. Whereas a theme is a complete structure designed for an entire website. 

2. Why You Need a WordPress Theme?

Every WordPress site requires a theme to display content online. Without a theme, you cannot show anything on your site; your site will appear as a blank page. A theme in WordPress has this important function of presenting the content stored in the database to the web.  

Due to this, a default WordPress theme will be automatically installed when you first install WordPress. Usually, the 3 latest default themes are pre-installed and the most recent one is activated.

It’s easy to recognize the default themes as they’re uniquely named after the year they’re released, like Twenty Twenty, Twenty Nineteen, etc. since the Twenty Ten theme in 2010. Explore all default themes.

You can easily change the default theme with any other theme and give a style to your site. And, there are thousands of free and paid themes to choose from. We’ll explain where you can find them in the sections below.

If you use a theme from the official repository, then you’ll get free support via the theme’s support forum page on Also, you’ll get free updates of the theme. Just an important thing is that, use the theme which is regularly updated and developed from the trusted authors. 


  • Since free themes cost you no money, it saves a big chunk of your budget.
  • Free themes are comparatively easy to use as they offer minimal features and have a clean code. 
  • You don’t have to worry about the theme malfunction if you’ve downloaded one from the official theme directory. That’s because they’re taken through a strict review process. And, most of the themes are compatible even with all the plugins.

  • Since the themes are free, they’re also more primitive in comparison to premium themes. 
  • They lack detailed customization options and have little or no live support included.

However, if you’ve just started, then a free theme might be the right option for you as it has just enough features to learn and build a basic website. Some of the best free themes you can try out: Astra, OceanWP, Zakra, Neve, and Ashe.

ii) Premium WordPress Themes

Premium themes require you to pay for them to use which generally has a reasonable price. These paid themes are usually more feature-rich and offer advanced customization options than free themes. And, that’s what you pay them for.

There are tons of marketplaces where you can find stunning premium WordPress themes. The biggest theme marketplace is ThemeForest, run by Envato Market. It features over 11,000 premium themes including the widely used themes like Avada, The7, Newspaper, etc.

  • Premium themes are usually loaded with tons of features, making it complex for beginners. Beginners may feel overwhelmed while using some premium themes.
  • The web page loading speed may decline with the lots of features used. 
  • Some premium themes may lack SEO features due to their complex structure. 
  • Some features provided by the theme may be irrelevant and thus, useless to your website.

The Freemium model of theme business is mostly common among theme developers who submit themes at the theme directory. You can see that most of the popular free themes listed there have paid versions on their company sites.

4. From Other WordPress Theme Developers

If you have other ideas for themes, you can also hire developers to make a theme for you according to your specifications. You can go for freelance developers or a WordPress-based web development company to make a suitable theme for you.

On the other hand, if you are a developer yourself, having coding knowledge of HTML, CSS, JavaScript, and PHP, then you can create and use your own theme on your site.

7. WordPress Themes vs. Plugins

A Plugin is a software that can be installed on your WordPress site to add new features and extend functionalities to it. Every plugin comes with its own special capabilities that could range from a small adjustment to a huge transformation.

Similar to free themes, there are thousands of free plugins available at Precisely, a lot more than themes, 57,000+ free plugins are available at the official WordPress plugin repository.

And, you can find tons of more plugins at other third party sites and marketplaces. is the larget plugin marketplace where you can find thousands of paid plugins.

The differences between WordPress themes and plugins are pretty clear. The theme is the main website layout that defines how your site appears on the web. Whereas plugins are for adding features to your site so that your site is capable of carrying out more functions.

Another difference is that you can use only one theme per WordPress installation but you can have several plugins at once as per the features you want on your website. 

Actually, a theme is mandatory for every WordPress site to show content online. But you can run a site even without a single plugin installed. 

However, there are some overlaps between those 2 terms. Sometimes, we come across themes that provide unique features as plugins do and removal of the theme also removes the features. On the other hand, some plugins can also facilitate managing the layout of the website.

But, their sole purposes are pretty obvious. Plugins are for adding features to the site whereas; themes are focused on how the sight appears.
