How to Delete Themes in WordPress: A Step-by-Step Guide

Choosing the perfect WordPress theme is a big part of building your website’s look and feel. Over time, you might test several themes or outgrow your current one. But what happens to those inactive themes cluttering your dashboard? Deleting unused WordPress themes is not only tidy but also improves your website’s security and performance. Let’s break down exactly how to delete a WordPress theme, why it matters, and answer the most common questions to help you manage your themes with confidence.

Why Should You Delete Unused WordPress Themes?

Before we dive into the steps, it’s worth understanding why deleting unused themes is a smart move:

Security: Inactive themes can have vulnerabilities. Removing them limits security risks.
Performance: Fewer themes mean less storage and quicker site backups.
Simplicity: Managing only the themes you use makes updates and troubleshooting easier.

It’s important to note that WordPress requires one active theme at all times—so you can’t remove the theme currently running your site.

What to Know Before Deleting a WordPress Theme

Deleting a theme is straightforward, but here are some useful points to consider first:

Back Up Your Website: Always back up your files and database before deleting themes. Most hosting services offer simple backup options.
Child Themes: If the theme you want to remove is a parent theme for an active child theme, don’t delete it. Your site needs the parent theme for the child theme to work.
Custom Code or Settings: Note that any customizations specific to the deleted theme will be lost.

4 Simple Ways to Delete a WordPress Theme

WordPress offers several ways to delete themes. Whether you prefer using the dashboard or a more manual approach, here are clear, step-by-step instructions for each method.

1. Delete a Theme via the WordPress Dashboard (Most Popular)

This is the easiest and safest method, especially for beginners.

Log in to Your WordPress Admin Panel
Use your usual login URL (often yourdomain.com/wp-admin) and enter your credentials.
Navigate to Appearance > Themes
On your sidebar, go to “Appearance”, then click on “Themes”.
Find the Theme to Delete
Identify the theme you want to remove. The currently active theme will be labeled “Active”—you can’t delete this one without switching first.
Click on Theme Details
Hover over the theme and click the “Theme Details” button.
Delete the Theme
In the bottom-right corner of the popup, click the red “Delete” link. Confirm when prompted.

That’s it! The theme is now gone from your WordPress installation.

2. Delete a Theme Using FTP or File Manager

This method is handy if you can’t access your WordPress dashboard.

Connect via FTP or Hosting File Manager
Use an FTP client (like FileZilla) or your host’s File Manager and log in with your credentials.
Browse to the Themes Folder
Go to wp-content/themes/ in your WordPress directory.
You’ll see each theme in its own folder.
Delete the Theme Folder
Right-click the folder of the theme you want to remove and select “Delete”.
Confirm your choice.

Be cautious here. Only delete the folder you’re sure you don’t need.

3. Delete a Theme Using WP-CLI

WP-CLI is for advanced users who are comfortable with the command line.

Open Your Command-Line Interface
Connect to your site’s server via SSH.

List Installed Themes
Run:
wp theme list
Delete the Theme
Run:
wp theme delete themename

Replace “themename” with the actual theme’s folder name.

4. Delete a Theme Through Your Hosting Panel

Some hosting platforms offer theme management tools right in their control panels.

Log in to Your Hosting Dashboard
Find the File Manager or WordPress management area.
Navigate to ‘wp-content/themes/’
Similar to using FTP, locate the folder of the theme you want to delete.
Delete the Theme Folder
Select and remove the unwanted theme.

What Happens When You Delete a WordPress Theme?

All files and assets specific to that theme are permanently removed from your server.
Any customizations made within that theme (not through plugins or child themes) will be lost.
Your content, posts, and plugins are not affected.

Benefits of Deleting Unused Themes

Deleting themes you’re not using comes with key benefits:

Reduced Vulnerability: Fewer points of attack for hackers.
Easier Maintenance: Less to update and manage.
Faster Backups: Smaller site means quicker backups and restores.
Cleaner Dashboard: Less clutter for you and other administrators.

Common Challenges When Removing Themes

You might run into a few issues:

Can’t Delete Active Theme: Switch to a different theme before trying to delete the current one.
Permission Issues: Sometimes file permissions prevent deletion. If so, use FTP or contact your host for help.
Child Theme Dependency: Don’t delete a parent theme if you use its child theme.

Best Practices for Managing WordPress Themes

To keep your site lean, secure, and efficient, follow these best practices:

Keep Only Active and One Default Theme: It’s smart to keep the theme you’re using and maybe one default WordPress theme as a fallback.
Update Frequently: Always keep your active theme updated for new features and security patches.
Regularly Audit Themes: Check which themes are installed and remove those you no longer need.
Back Up Before Changes: Before making changes, always back up your site to avoid accidents.

Cost-Related Tips

Deleting themes doesn’t cost a thing. However, here are a few tips that can save time and money in the long run:

Hosting Space: Fewer files mean you’re less likely to hit storage limits, which keeps hosting costs predictable.
Backup Costs: Smaller installations make for quicker, cheaper backups.
Bandwidth: Leaner sites can improve loading times, potentially reducing bandwidth usage and costs.

Conclusion

Deleting a WordPress theme is a straightforward process—whether you prefer using the dashboard, FTP, command line, or your hosting panel. Regularly removing unused themes secures your website, speeds up management tasks, and keeps things organized. Always back up your website before deleting anything, and only keep themes that are essential for your site to function.

Frequently Asked Questions (FAQs)

1. Will deleting a WordPress theme delete my website content?
No, deleting a theme will not remove your posts, pages, or media. Only the files specific to that theme are deleted.

2. Can I delete the active theme?
You cannot delete the theme that is currently active. First, activate a different theme, then proceed to delete the unwanted one.

3. Should I keep any extra themes installed?
It’s generally wise to keep one default WordPress theme (like Twenty Twenty-Two) in case you need a fallback, but remove all others you’re not using.

4. What happens to theme customizations after deletion?
Any custom code or settings you added directly within a deleted theme will be lost. Customizations made through child themes or plugins are safe as long as their dependencies remain.

5. Is it safe to delete a parent theme if I use a child theme?
No. If your active theme is a child theme, the parent theme must remain installed for your site to work properly. Deleting the parent will break your child theme.

By keeping your themes under control, you’ll enjoy a safer, faster, and more manageable WordPress site. Happy site-building!
