Why and When Should You Delete WordPress Themes?

What are WordPress Themes?

Basics of WordPress Themes


WordPress themes are akin to the skins or designs that dictate how your website appears to the visitor. They encompass the website’s layout, colour schemes, font styles, and even some functionalities.

At its core, a theme is a collection of files that work in unison to produce a graphical interface. These files determine the presentation and design of content on a website. By changing themes, users can swiftly alter the look and feel of their site without modifying the underlying content.


The difference between active and inactive themes:

Only one theme can be active on a WordPress site at any given time. This active theme is what visitors see when they browse the site. Inactive themes, on the other hand, are installed on the platform but not currently in use. They sit idly in your dashboard and, while they don’t affect the site’s appearance, they can still pose certain risks.


How Do Themes Impact Your WordPress Site?

Themes play a pivotal role in shaping the user experience on any WordPress site.

  • Speed and performance implications: A well-coded theme can boost your site’s loading speed, enhancing user experience. Conversely, a poorly designed or excessively inactive theme can lead to slow site speeds, adversely affecting SEO rankings and user engagement.
  • Security vulnerabilities with outdated themes: Themes, like any software, can have vulnerabilities. If they aren’t regularly updated, these vulnerabilities can be exploited by malicious actors, putting your site at risk.
  • User experience and design consistency: A good theme provides a consistent design across different pages, leading to better navigation and user engagement. A sporadically updated or mismatched theme might disrupt this consistency, leading to a disjointed user experience.

Enhancing Website Performance

Unused themes, though inactive, occupy valuable server space.

  • How excess themes can bloat your website: Each theme, active or not, stores files on your server. Over time, as these pile-up, they can consume valuable resources, leading to a slower website.
  • Speed optimization benefits of theme decluttering: By removing unnecessary themes, you free up server space, potentially boosting the site’s speed and overall performance.


Reducing Security Risk

Every theme is a potential doorway for hackers if not properly maintained.

  • Themes that are no longer supported by their developers don’t receive security patches. This makes them prime targets for hackers.
  • Even if a theme isn’t active, a hacker can exploit its vulnerabilities to gain unauthorized access to a website.


Maintaining a Cleaner WordPress Dashboard

A streamlined dashboard can enhance productivity and reduce errors.

  • With fewer themes to sift through, navigating the dashboard becomes simpler, making site management more efficient.
  • A cluttered dashboard can be overwhelming for newcomers. By keeping it clean, you ensure smoother onboarding and fewer errors in website management.



Unused themes can become outdated and may not receive updates, leaving them vulnerable to security exploits. Hackers can target these themes to gain access to your website.


Updates and Maintenance

Each theme installed on your WordPress site requires regular updates. Having multiple unused themes means more maintenance work, which can be time-consuming and potentially problematic if an update causes issues.


Disk Space

Themes, especially those with high-end graphics and functionalities, take up valuable disk space. Removing unused themes frees up space, ensuring your hosting resources are used efficiently.

  • Simplification: A more simplified WordPress dashboard makes managing your website easier. With fewer themes, you can avoid confusion and focus on the themes you actually use.
  • Avoid Conflicts: Sometimes, themes can conflict with each other or with certain plugins. By eliminating unused themes, you reduce the risk of such conflicts.
  • Focus on Quality: By keeping only the themes you use, you can focus your attention on keeping these themes up-to-date and optimized, ensuring a better quality for your website.


When Should You Consider Deleting a WordPress Theme?

After Switching to a New Theme

Transitioning to a new theme is common, but it’s vital to manage the aftermath properly.

Once you’ve ensured that the new theme is working seamlessly, it’s a good practice to remove the old theme to avoid unnecessary clutter.

Keeping a backup or default theme: While decluttering is essential, it’s prudent to keep a backup, like the default WordPress theme, in case of emergencies.


When the Theme is No Longer Updated

Outdated themes are potential liabilities.

  • Risks of using outdated themes: Using themes that aren’t regularly updated can expose your site to security vulnerabilities and compatibility issues with newer WordPress versions.
  • Finding out if a theme is no longer supported: Check the theme’s update history, and if there’s been a prolonged period without any updates or support from the developer, consider it a red flag.
  • Accumulated Multiple Unused Themes Over Time: It’s easy to amass themes, but regular audits are necessary.
  • Periodic audits for theme decluttering: Schedule regular checks of your theme library, removing any that you no longer use or require.
  • Signs that it’s time for a clean-up: If you find that you’re scrolling through numerous themes to find the one you need or your site’s speed is lagging, it might be time for a clean-up.

Q: What happens to my content if I delete a theme?

Your content remains safe. Themes only dictate how content is displayed, not the content itself. Deleting a theme won’t erase posts, pages, or media.


Q: Can I reinstall a deleted theme later?

Yes, unless it’s a premium theme that you no longer have a license for, you can reinstall any theme from the WordPress theme repository.


Q: How often should I review and clean up my themes?

It’s advisable to review your themes at least once every quarter. Regular audits ensure your site remains secure and performs at its best.


Q: Is it okay to keep one backup theme? Why or why not?

Yes, it’s a good practice to keep a well-coded backup theme (like a default WordPress theme). It acts as a safety net in case your active theme runs into issues.


Q: How do I know if my theme is a security risk?

Regularly check for theme updates. If a theme hasn’t been updated in a long time or has poor reviews regarding security, it may be a risk. Tools like WPScan can also help identify vulnerable themes.
