If you use text boxes as a design element in your documents, you may want a way to create a text box that is a particular width but has no set height. This would allow the height of the text box to expand, based on the amount of text you place in it, without adjusting the width and messing up your page layout.
There are a couple of things you can try. First, you should try formatting the text box so it can expand. Follow these general steps.

Figure 1. The Text Box options of the Format Shape pane.
When performing these steps, make sure you set the width of the text box (step 2) separate from specifying the "resize" setting (step 5). You'll note that the Size tab of the Format Text Box dialog box allows you to set the width of the text box. If you set the width and the check box at the same time, then some versions of Word take that as an indication that it is OK to resize the width of the text box as necessary. (Go figure—sounds goofy, but it seems to work.)
