The art & science of viral thumbnails: A comprehensive guide
September 19, 2024
In 2024, YouTube remains a content behemoth, and one of the most important factors influencing the success of your video isn’t your content—it’s your thumbnail. If viewers don’t click, they don’t watch. It’s that simple. Yet, creating a viral thumbnail is not just about slapping together a flashy image with bold text. It’s a combination of design principles, emotional cues, and emerging trends that collectively determine whether viewers will stop scrolling and engage with your content.
In this comprehensive guide, we’ll break down the art and science behind creating viral YouTube thumbnails in 2024, while also diving deep into data-driven insights on what’s working today. Let’s start with the foundational principles of design and move into the latest trends influencing what gets viewers to click.
Design principles: Mastering the basics for maximum impact
Thumbnails are the first impression of your video, and as such, they need to be visually striking, clear, and emotionally engaging. Let’s break down a few key design principles that can help make your thumbnails pop.
The rule of thirds: Organizing visual elements
The rule of thirds is a timeless design technique, frequently used in photography, and highly applicable to thumbnail design. The principle suggests dividing your thumbnail into nine equal parts with two equally spaced horizontal lines and two vertical lines. The key objects of your thumbnail should be placed along these lines or their intersections. This composition technique naturally draws the viewer’s eye, creating balance and focus in your design.
You can see this in the most successful thumbnails of major YouTubers like MrBeast, who often places a shocking or emotional face right along these lines to grab attention. By following this layout rule, you prevent clutter and ensure a natural flow of visual information that quickly communicates the core of your video.
Choosing the right colors: Contrast and consistency
Another crucial aspect is color choice. Many creators default to using overly complicated color palettes, but simplicity is key. The idea is to create contrast—making your thumbnail stand out against the sea of videos on the YouTube homepage.
One effective approach is to choose a primary color and complement it with two or three contrasting colors from the color wheel. For example, MrBeast frequently uses a yellow-blue combination that catches the eye without overwhelming it. Remember, the point is to draw attention, not to overload the viewer’s senses.
However, a lesser-known trick is consistency. If you want your channel to be recognizable, stick to a consistent color palette. But here’s the catch: change one highlight color from time to time to keep things fresh while maintaining your brand identity.
Typography and visual effects: Keep it clear
Font choice is another design element often overlooked. Your text needs to be clear, bold, and easily readable, even on small mobile screens. Stick with basic, recognizable fonts that aren’t overused but still provide clarity. The general rule is to use fewer than four words per thumbnail, allowing the image to do the heavy lifting.
Visual effects like drop shadows, outer glows, and embossing can give your text dimension, helping it stand out from the background without making the thumbnail too busy. Simplicity is key here—don’t let effects clutter the image.
Thumbnail types that work in 2024: Data-driven insights
While design principles are important, you also need to consider current trends. Nate, from @ThatNateBlack reviewed in his video thousands of thumbnails to discover the categories that are consistently performing well on YouTube today. Understanding these types and when to use them can significantly boost your video's click-through rate (CTR). Let’s break down these top-performing thumbnail types:
1. Collage thumbnails (29.4%)
Collage thumbnails are a powerful way to visually convey multiple ideas or elements at once. In this type of thumbnail, different objects or scenes are combined to create an impactful visual narrative. A perfect example comes from channels like @Mrwhosetheboss, who uses this style to showcase tech gadgets or comparisons.
This category allows for flexibility, especially for creators looking to fit several focal points into one image. It’s an effective style when you want to showcase a variety of features or tell a more complex story that requires more than one visual cue.
2. Showcase thumbnails (25.4%)
As the name suggests, showcase thumbnails focus on a primary object or person. Whether it’s a close-up of a product, a person’s face, or a specific event, this thumbnail type thrives on simplicity and focus. This works especially well for food channels or tech reviews, where one central object (like a delicious meal or a gadget) takes center stage.
For example, in food channels like @PickUpLimes, the food itself is showcased with bright, vibrant colors to entice the viewer. These thumbnails often use minimal text to let the image speak for itself, making them easy to understand even at a glance.
3. Split Frame thumbnails (11.2%)
Split frame thumbnails are especially useful when you want to show a before-and-after scenario or compare two things. These are very popular in the tech and beauty niches, where you might showcase a product on one side and its result or performance on the other.
For example, @AliAbdaal frequently uses this type of thumbnail for productivity videos, showcasing a “before” state of disorganization and an “after” state of clarity or success. This taps into the viewer’s curiosity and promises a transformation, making it highly clickable.
4. Reaction thumbnails (23.9%)
Reaction thumbnails focus on facial expressions, which are among the most effective ways to convey emotion quickly. Studies show that humans are drawn to faces, and this is why reaction thumbnails—where creators display exaggerated emotions—tend to work so well. These thumbnails capitalize on the emotional connection between the viewer and the creator, making them especially effective for entertainment or commentary videos.
Think of popular YouTubers like @DoctorMike or @StevenHe, whose reaction thumbnails communicate excitement, shock, or disgust. These emotions pull viewers in, wanting to know what caused such a strong reaction.
5. Single action or movement thumbnails (10.4%)
Thumbnails showing a clear action or movement are particularly engaging because they hint at what will happen in the video. These thumbnails often capture a dynamic moment—like a person performing a task or an object mid-transformation—which makes the viewer curious to see the action unfold.
Channels like @Donut frequently use this type of thumbnail for car tests, where something is happening in real time (like a crash test or a tire burnout). This gives the viewer a sense of immediacy and action, making it hard to resist clicking.
Emotional appeal: The secret to engagement
One of the key findings from the analysis of thumbnails is the role of emotions. Happy and excited expressions accounted for 25.3% of the most successful thumbnails, while neutral expressions came in a close second at 25.1%. These emotions are critical in building a connection with the audience and hinting at the mood of the video.
Interestingly, the least-used emotion was sadness, appearing in just 1.8% of thumbnails. This is not surprising, as most viewers turn to YouTube for uplifting or educational content. Using emotions strategically in your thumbnails—whether it’s excitement, surprise, or even fear—can significantly boost CTR.
Additionally, remember that showing faces in your thumbnails (75.57% of successful thumbnails) can dramatically increase emotional engagement. Faces are instantly recognizable, and they help viewers form a quick emotional connection.
Getting inspiration: Where to find ideas for fresh thumbnails
As a creator, finding inspiration for your next thumbnail is key to keeping your designs fresh and engaging. Sticking to the same formula will eventually fatigue your audience, so mixing things up is essential for long-term success.
Look outside your niche
One of the best ways to find new thumbnail ideas is to explore channels outside your niche. If you’re creating tech reviews, browse travel or cooking channels for inspiration. This approach ensures that your content stands out within your niche while borrowing innovative ideas from other fields.
Use tools to discover what works
Another way to stay on top of trends is to use powerful tools like glowAI’s outlier search tool. This tool helps you identify unique and trending thumbnails that are performing well across YouTube. It can analyze visual trends and give you inspiration from top-performing videos that might not be on your radar. Using this tool allows you to keep your thumbnails fresh and stand out from the competition.
Testing and iterating: The path to perfection
Creating the perfect thumbnail isn’t just about theory; it’s also about practice. One of the best ways to ensure your thumbnail will perform well is to test it. You can use tools like ThumbsUp.tv to simulate how your thumbnail will look on YouTube's homepage and test its visibility among other videos.
Experiment with different styles, emotions, and color schemes, and don’t hesitate to pivot if something isn’t performing as expected. Top creators like @veritasium constantly test and refine their thumbnails to discover the most effective designs. The images below show the initial thumbnail (left) and the final, optimized version (right) that resonated better with his audience. While the first thumbnail was already visually appealing, it didn’t perform as well as the optimized version. This highlights the importance of experimenting with multiple concepts, as it’s often difficult to predict which one will succeed.
