Why are YouTube thumbnails important?
A YouTube thumbnail is important if you want your YouTube channel to be a success; let’s look at some reasons why you should take creating good thumbnails seriously:
- A good YouTube thumbnail is an excellent way to increase rankings on YouTube‘s SEO. It influences how videos are found and preferentially recommended, besides making the audience’s mind positive towards the video.
- The thumbnail is a glimpse of the video’s content that represents what viewers can expect from the video.
- Ultimately, it increases the customer base of the channel. If the video and thumbnail are together, an attractive thumbnail is the deciding factor in attracting viewers.
Furthermore, it adds an extra edge to your YouTube channel promotion, as a well-designed thumbnail shows the professionalism of the content.
Best practices for creating a great YouTube thumbnail
A thumbnail should match the content of the video well, which should be unique, bold, attention-grabbing, attractive, on-brand, and of high quality. It determines the click rate of the video, so creators have to try to make the best impression the first time they are viewed.

Here are some key points that can make a great YouTube thumbnail:
#1. Size of image
YouTube thumbnails start with the size of the featured image, which should be of appropriate size and dimensions. According to YouTube guidelines, the thumbnail image should be 1280 x 720 pixels with a width of 640 pixels.
The 16:9 ratio is a perfect match for pitching audiences, as it is most commonly used in previews. The thumbnail size may be, at most, the YouTube instructions. The larger size image may move down instead of the smaller size. It ensures that the highest image quality is maintained. A JPG, GIF, BMP, or PNG format of less than 2 MB is required.
#2. Thumbnail background
The strong visuals of thumbnails attract viewers to watch the video. The background that includes the context of the video provides an opportunity to become familiar with the video at first glance. The image must match the main content.
#3. Title text in thumbnail
The text added on the thumbnail gives detailed context about the featured image. The effectiveness of thumbnails becomes more affected because the text communicates with the audience on behalf of the image.
#4. Fonts practice
The essential factor to keeping the audience engaged is introducing them to the content. It is believed that having the same font style and color for each thumbnail deeply impacts people, which is why branding should be consistent. The font should be clear and easy to read so that the audience sees it the first time they see it. Bold and heavy fonts are also a good choice, but avoid scripted fonts. Furthermore, if you do not have a brand kit already, consider creating a brand kit!

#5. Branded thumbnail template
Branded YouTube thumbnails mean consistency of the same template across all videos. The template reflects the business, whether it is a prominent brand image or a fit for the niche. The presented template attracts the audience and impacts the audience’s mind for future traffic.
#6. Thumbnail as teaser
Audience trust and reliance on video is the future potential for brand advocacy and growth. Using the right thumbnail per the video content makes them trust the creator. Keep the best part of the video as a thumbnail or set a short teaser without highlighting the best part. These methods create excitement in the viewers’ minds to click on the video.
However, misrepresenting videos on thumbnails is considered clickbait, which reduces brand value. Clickbait can lead to loss of traffic to the video or even the channel getting affected. Thus, it is important to employ the right marketing strategy.
