What to write

  • Say what matters in the picture: who’s in it, what they’re doing, where it is.
  • Copy out any words in the picture, like a sign or a menu.
  • With several photos, describe each one briefly, in order.

You have up to 1,000 characters. A counter shows up when you get close.

Good to know

  • Screen readers like VoiceOver and TalkBack read it out when someone reaches your photo. Nobody else sees it.
  • You can’t add or change alt text once the post is shared, so add it before you tap Share post.
