Key Tips for Mobile Thumbnail Optimization
Optimize thumbnails with these strategies:
1. Use Mobile-Friendly Sizes
Design for 1280x720px (16:9) but ensure key elements are visible in the center 640x360px area, as mobile crops edges. Test with YTDFree.Online’s WebP/HD downloads.
2. Prioritize Readability
Use large, bold fonts (e.g., Inter, 40–60px) with high contrast (e.g., white text on dark backgrounds). Limit text to 4–6 words for clarity.
3. Leverage High-Contrast Colors
Bright colors like red or yellow grab attention on small screens. Use AI tools like Runway to test color effectiveness.
4. Simplify Imagery
Use clear, bold images (e.g., faces or single objects). Avoid cluttered designs that lose impact on mobile.
5. Ensure Accessibility
Add alt text to thumbnails for screen readers (WCAG 2.2, 2025). Use high-contrast colors for colorblind users.
