How to Remove Themes from WordPress: Step-by-Step Guide
If you’ve been experimenting with different WordPress themes for your website, you might find your dashboard cluttered with old or unused themes. Removing these unused themes isn’t just about tidiness—it helps improve your site’s security, makes managing updates easier, and can even speed up your WordPress admin area. In this comprehensive guide, you’ll learn exactly how to delete WordPress themes safely, efficiently, and without worry.
Why Remove Unused WordPress Themes?
Before jumping into the steps, it’s helpful to understand why deleting unused WordPress themes is important:
- Security: Outdated themes can be vulnerable to security exploits, even if they’re inactive.
- Performance: Extra files mean more backend clutter, potentially slowing down backups and increasing server load.
- Management: Fewer themes lead to less confusion, especially when updating or troubleshooting your site.
What You Should Do Before Deleting a Theme
Before you permanently remove a theme, take these important precautions:
1. Make a Complete Backup
Always back up your WordPress site (files and database). This way, if something goes wrong, you can quickly restore it.
2. Check If the Theme Is Active
You cannot delete a theme that’s currently active. Make sure you have switched to another theme.
3. Consider Child Themes and Customizations
If you’ve made custom modifications or have child themes based on the one you wish to delete, double-check which files are in use.
Methods to Remove a WordPress Theme
There are several ways to delete a WordPress theme. Here are the most common and user-friendly methods:
Method 1: Deleting a Theme via the WordPress Dashboard
This is the most recommended and easiest way for most users:

Go to Themes Page
In the left-hand menu, click onAppearance>Themes. -
Select the Theme to Delete
Hover your mouse over the theme you want to remove. Ensure it’s NOT the active theme (the currently used theme says “Active”). -
Click on Theme Details
Click the theme’s thumbnail or theTheme Detailsbutton. -
Delete the Theme
In the lower-right corner of the pop-up window, you’ll find a redDeletebutton. Click it. -
Confirm Deletion
When prompted, clickOKto confirm. The theme will be removed from your WordPress installation.
Benefits of This Method
- No technical skills required
- Safe and suitable for beginners
- No access to FTP or hosting panels needed
Method 2: Deleting a Theme via FTP or File Manager
If you can’t access your WordPress dashboard, you can delete a theme using FTP (File Transfer Protocol) or your web hosting’s File Manager:
- Connect to Your Website via FTP
Use an FTP client (like FileZilla) or log into your hosting’s file manager tool.
-
Navigate to Themes Directory
Go towp-content/themes. -
Find the Theme Folder
Each theme is in its folder named after the theme (e.g., “twentytwentyone”). -
Delete the Theme Folder
Right-click and delete the folder of the theme you wish to remove. -
Check Your Website
Visit your site to ensure everything works as expected.
When to Use This Method
- You’re locked out of your dashboard
- The dashboard method isn’t working
- You prefer direct file management
Method 3: Deleting a Theme via WP-CLI
WP-CLI is a command-line tool for WordPress power users. If you have SSH access:
- Connect via SSH
- Navigate to the Site’s Directory
-
List Installed Themes
Run:
wp theme list -
Delete the Theme
Run:
wp theme delete themename -
Confirm Deletion
Why Use WP-CLI?

- Avoids the dashboard entirely
Best Practices When Removing WordPress Themes
-
Keep One Default Theme
It’s smart to keep a default WordPress theme (like Twenty Twenty-One) as a fallback in case your active theme fails. -
Update or Remove Outdated Themes
Don’t let old, insecure themes linger on your server. -
Test Your Site After Deletion
Browse your website and key pages to ensure nothing is broken. -
Remove Associated Theme Plugins and Widgets
Some themes come with plugins or widgets that should also be deleted if no longer needed.
Potential Challenges and How to Overcome Them
-
Can’t Delete the Active Theme
You must activate a different theme first. -
Accidental Deletion of Active Theme
If you use FTP or WP-CLI, double-check the active theme. Deleting it could break your site’s appearance. -
Customizations Get Lost
If you’ve made customizations directly in the theme files (without using a child theme), back up those files or take note of changes before deletion. -
Database Orphans
Deleting a theme doesn’t always remove related options or data from the database. Consider using a database cleanup plugin if you’re concerned about leftover clutter.
Tips for Efficient Theme Management
-
Regular Check-ups
Periodically review installed themes and plugins to keep your site lean and secure. -
Use a Staging Environment
If you have access, test removals in a staging site before changing your live site. -
Document Changes
Keep a record of the themes you use and modify. This makes upgrades and troubleshooting much simpler. -
Avoid Downloading Themes from Unreliable Sources
Only install themes from reputable sources to avoid malicious code and compatibility issues.
Cost Considerations
Deleting themes from your WordPress site is completely free and does not affect your hosting or your subscription costs. However, be cautious if you have purchased a premium theme; deleting it does not cancel your license or subscription with the theme provider. Make sure you manage those costs directly with the provider if needed.
Conclusion
Removing unused themes from your WordPress site keeps it secure, efficient, and easy to manage. Whether you use the dashboard, FTP, or WP-CLI, the process is straightforward as long as you make the proper preparations. Remember to always have a recent backup before making changes, keep at least one default theme available, and test your site afterward. A tidy WordPress installation means better performance, reduced security risks, and a smoother admin experience.
Frequently Asked Questions (FAQs)
1. Can I delete the active WordPress theme?
No, WordPress will not allow you to delete the currently active theme through the admin dashboard. You need to activate a different theme first before you can remove the one in use.
2. Will deleting a theme delete my content or posts?
No, deleting a theme does not affect your site’s posts, pages, or media. However, any theme-specific customizations, widgets, or settings will be lost if they’re not compatible with your new theme.
3. Should I keep all my downloaded themes for backup?
It’s best to keep one default theme (like Twenty Twenty-One) as a safety net, but you do not need to keep multiple inactive themes. Unused themes can be a security risk and clutter your site.
4. How can I tell which theme is active?
Go to Appearance > Themes in your WordPress dashboard. The active theme is labeled “Active” at the top. Make sure not to delete this one unless you first activate a different theme.
5. What happens if I delete a theme by accident?
If you’ve made a backup, you can restore your site easily. Otherwise, you can always reinstall the theme via the WordPress theme repository or by uploading a theme ZIP file—though customizations made directly to the theme files may be permanently lost.
Cleaning up your WordPress themes is good housekeeping for your website. By following these straightforward steps, you’re laying the groundwork for a faster, more secure, and easily manageable WordPress site. Happy tidying!
