Build high-contrast thumbnail concepts with a clear subject, focal point and readable composition.
1. Define the promise of the video
Write the one idea the thumbnail should communicate before generating anything.
2. Keep the composition simple
Use one main subject, strong separation from the background and room for short text if you plan to add it.
3. Generate visual options
Try different crops, expressions and background directions rather than changing every element at once.
4. Check at small size
A thumbnail that looks good at full resolution can fail in a feed. Preview it small and verify that the focal point remains obvious.
