Thumbnail Best Practices

  • Text readability: Use large, bold text (3-5 words max). It must be legible at 168x94px — the size shown in suggestions on mobile.
  • Mobile preview: 70% of YouTube views are on mobile. Check your thumbnail at small sizes before uploading.
  • High contrast: Bright backgrounds with dark text (or vice versa) stand out in feeds.
  • Faces and emotion: Thumbnails with expressive faces consistently get higher CTR.
  • Avoid clutter: One focal point, one emotion, minimal text. The title handles context.
  • Don't duplicate the title: Your thumbnail and title should complement, not repeat each other.
