Troubleshoot YouTube Showing Large or Zoomed-in Thumbnails on Subscription Page Error

We’ll walk you through the troubleshooting steps in this manual to resolve the issue where YouTube displays oversized or zoomed-in thumbnails on the subscription page.

Clear Browser Cache and Cookies

Frequently, display issues on YouTube can be fixed by clearing the cache and cookies in your web browser. Your browser’s cache and cookies may become corrupted or out-of-date over time, which may have an impact on how webpages show.

Take the following actions to erase the cache and cookies:

  • Launch a web browser.
  • Visit your browser’s options or preferences page.
  • Look for a button to delete browsing history.
  • Choose the option to clear cookies and cache.
  • Restart your browser and see if the thumbnails have reverted to their original sizes on the subscription page.

Use YouTube’s Old Design

Try going back to YouTube’s original design if clearing the cache and cookies doesn’t fix the problem. The issue might be resolved by using the old design, which might display thumbnails in a different size.

Take these actions to access the previous design:

  • Write down the URL of the YouTube page you’re now on.
  • After the YouTube URL, add the URL parameter “&disable_polymer=true”.
  • For instance, substitute “” for “”.
  • The YouTube page will load using the previous layout, and the thumbnails might show up in their full size.

Verify that the old look of the subscription page is still correctly displaying the thumbnails.

Try a Different Browser When Launching YouTube

It may be worthwhile to try using a different web browser to visit YouTube if the problem continues. A different browser might occasionally help to overcome display issues that are sometimes browser-specific.

Install a different browser, such as Microsoft Edge, Mozilla Firefox, or Google Chrome, and check to see if the thumbnails on the subscription page display in the proper proportion.

Install Userstyle or Extension

Using userstyles or browser add-ons, some users have had success changing the YouTube thumbnail size. The issue of thumbnail size is explicitly addressed by userstyles or extensions that are available.

One illustration given is the userstyle “berny23-s-youtube-enhancements.” Installing userstyles or browser extensions that are specifically designed to change YouTube thumbnail size is possible.

These userstyles or extensions can offer options to personalize the thumbnail display, allowing you to adjust them to the size you desire.

Provide Feedback to YouTube

If none of the aforementioned fixes work, it’s critical to inform YouTube about the problem. User feedback is something that YouTube values and takes into account when making platform improvements.

To report a problem and share your experience, go to the YouTube Help Center or the Community forums. By offering feedback, you help in the continual improvement and growth of YouTube, and your suggestions might aid in resolving the thumbnail display problem.

It’s important to note that YouTube experiments and rolls out updates to its platform from time to time, including new thumbnail styles. As a result, thumbnail appearance may change depending on YouTube’s continuous testing.

It’s a good idea to regularly check YouTube’s official announcements and release notes to learn about any updates or changes.
