Adobe InDesign CS6 allows you to have text frames auto-size to fit the text you’re typing or placing into them. This can be a real time-saver, and it’s easy to set.
To turn Auto-Size on, right + click on a text frame and select Text Frame Options, or simply hit Command + B. In the dialog window, click the Auto-Size tab at the top right and choose your settings.
In the Auto-Size tab, you can set your text frames to automatically grow in specified directions, and by minimum amounts if you choose.
If you’re placing a long text document, the frame will grow to the bottom of the pasteboard.
