Header tips

  • Keep text and logos near the center: the edges are cut differently on phones and computers.
  • Leave the bottom-left area empty; the profile picture sits on top of it.
  • Use the same visual style as your profile picture so the profile looks like one brand.

Count your post with the X character counter, check an account's real creation date with the X account age checker, or see aged X accounts.
