You can create a gap between paragraphs in two ways:

  • Use the Text tool to insert blank lines between paragraphs by pressing Return or Shift+Return.
  • Choose Text > Spacing to open the Spacing palette.

    The Spacing dialog box enables you to dictate the exact size of gap in units of your choice – mm, inch, pt.

There is no gap between any of the paragraphs shown right.

Here the spacing has been changed to 6 points.

Select multiple paragraphs to alter the spacing of them all at once.
