Reply To: Pasting .txt lists into Indesign pages

ID does not have a feature that sizes text to frames, but there is a feature in the Text Frame Options dialog box that lets you size frames to the text.

I strongly recommend learning a bit more about how text flows into InDesign master page text frames. It doesn’t have to go margin to margin. You can place a frame on a master page and then use File > Place to put the text into it and have it flow automatically.

Search the site here for placing text or flowing text. There are a lot of videos about this at lynda.com also (including my own Essential Training title).
