YouTube Thumbnail Size

The best YouTube thumbnail size is 1280 x 720 pixels. That means 1280 pixels wide and 720 pixels tall. The minimum width of the thumbnail should be 640 pixels. Ideally, you want to choose a thumbnail with a 16:9 aspect ratio.

The thumbnail of your YouTube video absolutely has to be optimized if you want to get more views. In fact, thumbnails are just as important as the title of the video when it comes to grabbing the viewer’s attention.

Importance of Thumbnails

It’s no wonder that many YouTube videos get millions of views just by using ‘clickbait’ titles and thumbnails. How often have you seen a ‘snake vs giraffe’ thumbnail where the actual content does not have a snake fighting a giraffe. Of course, this practice is looked down upon and you never want to attempt to do something similar.

A video’s thumbnail is also displayed in the Google search results, so be sure to choose something that is attention-grabbing, high quality and descriptive. Your video could be competing with Google search results, so be sure to optimize both the title and thumbnail to stand out.

In order to help you make the best YouTube thumbnails, we’ll discuss everything you need to know about them and best practices you can follow to maximize your views. Let’s start.

Here’s a summary of YouTube thumbnail size and requirements:

  • Size: 1280 x 720 pixels
  • Minimum width: 640 pixels
  • Thumbnail file size: 2MB maximum

Understanding YouTube Thumbnail Dimensions

Resolution

The resolution of an image is the number of pixels in the image, the more the better. Google recommends images with a resolution of 1280 x 720 pixels for YouTube thumbnails. If you use lower resolution images, they’ll look pixelated in video previews.

Minimum width

The minimum width of a YouTube thumbnail is 640 pixels. Any lower and YouTube will refuse to use your image as a thumbnail. Ideally, you should aim for images that are 1280 pixels in width.

Thumbnail file size

The image you want to use as the thumbnail should not be greater than 2MB. Any greater and YouTube will reject your upload. You can use a number of free software to decrease the file size of your images. Even MS Paint can do the job if you save image as JPG.

File types

Images file types of JPG, GIF, BMP or PNG are allowed to be used as YouTube thumbnails. If you have an image that is a different file type, you can use an online converter to sort this issue.

Aspect ratio

The aspect ratio is the width of the image relative to its tallness. For YouTube, your image should be 16 units wide and 9 units tall ideally. 16:9 is the most popular format for YouTube videos.

TIP: You can change the thumbnail for a video at any time, no matter when it was uploaded.
