If you can’t add custom thumbnails, it means your channel has not yet been verified. So, first, check whether it’s verified.

Not sure how to verify the YouTube account, then read the detailed article below:

Ok, now let’s get into the main topic.

When you’re trying to upload a custom thumbnail, the image should satisfy some of the limitations that YouTube recommends.

YouTube Thumbnail Size & Requirements:

  • Size: The size of the thumbnail image should be under 2 MB
  • Format: Image file formats must be any one of PNG, JPG, or GIF
  • Ratio: The ratio of the image could be 16:9
  • Pixels: 640 pixels

By default, YouTube suggests the three thumbnail options from the video frames. If you think those are more relevant to the video, you can select those, too.

Add thumbnail to YouTube Video

Generally, the trouble for creators when choosing the thumbnail is which one will work and get us more views.

It’s possible when you analyze your thumbnail with the help of specific AI tools.

Let me explain below how you can find the best thumbnail that will work out for your video.

Thumbnail Performance

First, use your favorite software, such as Canva or any other, to create a combination of at least three thumbnails for one video.

We created three thumbnails for a single video because we will now test and analyze which one best fits your video,making your content more engaging and appealing.

The question here is, how can I analyze and find the best thumbnail out of the three?

Well, the answer is that you need a thumbnail analyzer tool called TubeBuddy. It helps you test and find high-CTR conversion thumbnails.

Once you install TubeBuddy and click the Thumbnail analyzer button, you can add the list of thumbnails you want to test. Finally, the best one will look like the above image. The higher the percentage, the higher the ranking chance.

After all the analysis, once you’ve uploaded the custom thumbnail, it looks like this (see the image below).

  1. Hi,

    On my brand channel, when I change the thumbnail for a playlist, the thumbnail on the playlist does change, but the change is not reflected on the playlist on my channel home page.

    I can’t seem to find anything that will remedy the situation, and hope you can point me in the right direction.
