Social graphics compete inside a 3-centimetre rectangle against a hundred others. Everything must read in under one second at thumbnail size.

  • Three elements maximum: subject, three to five words of text, one accent.
  • Faces and eyes outperform objects — emotion drives clicks.
  • Extreme contrast: bright subject on dark background, or the inverse.
  • Text must be legible at 20% zoom. Test by shrinking it.
  • Consistent template = channel recognition in the feed.
