Readable at 100px width (mobile preview) 2. Face takes 40-60% of frame 3. Maximum 5 words of text 4. High contrast between elements 5. Consistent brand style ### CTR Optimization 1. Test multiple versions 2. Study competitor thumbnails 3. Match thumbnail to title 4. Create curiosity gap 5. Use proven color combinations ### Common Mistakes to Avoid 1. Too much text 2. Low contrast colors 3. Busy backgrounds 4. Small faces 5. Misleading imagery --- ## Reference Materials For detailed code examples and implementation patterns, see [references/examples.md](references/examples.md).
