YouTube is undeniably the most widely-used video sharing platform. It’s free, simple, and offers an exciting platform to upload your local videos. However, research has it that the average YouTube viewer will, first of all, look at the video thumbnail before opening it. Therefore, getting an engaging YouTube banner is the way to go. But do you know the perfect YouTube thumbnail size? If you don’t, fret not because this article will give you a detailed explanation of how to create the perfect YouTube video thumbnail size to attract more views.

Part 1. What is the Perfect Size of a YouTube Thumbnail

A video thumbnail image is like a book cover. It is what viewers will look at first before opening a YouTube video. So, if you want your YouTube video to stand out from the crowd, the YouTube video thumbnail size is just as important as the image quality. However, most people get it all wrong when it comes to the thumbnail size. In an ideal world, a thumbnail should be at least 1280 (w) x 720 (h) pixels.

Surprisingly, the image won’t be displayed at 1280 x 720 pixels because it will be larger than this. The larger size will give your image more flexibility and quality when it’s embedded on external sites or blogs. In short, a thumbnail with a lower pixel might be blurry on some displays. Also, the 1280 x 720 pixels is perfect for YouTube’s 720p videos, which is the minimum threshold for HD videos.

Part 2. The Maximum and Minimum size for YouTube Thumbnail

Usually, YouTube supports up to 4K video quality with 3840 x 2160 pixels. It also supports 2K videos with 2560 x 1440 pixels. As for 1080p HD videos, the maximum pixels are 1920 x 1080, whereas the typical 720p videos have 1280 x 720 pixels. The minimum width dimension for any YouTube thumbnail should be 640 pixels. You can even upload up to 144 pixels, but that’s not recommended because the image will be of low quality. So, it’s best to stick to the average 1280 x 720 pixels range.

Note: To avoid having black bars on either side of your image, the recommended aspect ratio for your thumbnail is 16:9. Also, the maximum image size is 2MB. If it surpasses that, you’ll receive a “File is bigger than 2MB” message.
