About

Turn a video idea into a thumbnail people can understand at a glance. Tell HowWorks what the video is about, who it is for and which moment or contrast should draw attention. Choose one focal subject, a readable silhouette and a background that supports it. Use a reference when the composition or visual style matters. Check the result at the small size viewers will see, then finish any title text in your layout. The image should make a clear promise that the video itself can deliver.

Questions

What makes a useful thumbnail brief?

Name the video topic, the central object or action, and what the viewer should understand at a glance. Describe the composition and where text will go. Avoid asking the image to tell several unrelated stories at once.

What shape does this page start with?

The thumbnail preset uses a landscape 16:9 format. Compose for that frame from the beginning and keep essential details away from the edges.

Can I use different visual styles?

Yes. Ask for a photographic scene, illustration or graphic composition that suits the video. A consistent point of view matters more than applying the same style to every topic.

Will this increase my click-through rate?

A generated thumbnail is a visual concept, not a performance guarantee. Click behavior depends on the audience, topic, title, placement and other factors. Evaluate the final thumbnail with your own publishing data.

How much text should I include?

Keep the message short enough to read at the size it will appear. You can request clear space for type and add the final words separately. Check spelling, contrast and whether the image still communicates when the text is removed.
