There are two ways you can modify the size of a frame:
Sizing the frame directly, using the mouse
Click in a frame to make it active - so that the frame edges are visible.
Click anywhere on the border of the frame so that the eight resize boxes appear.
Click on any resize box and drag the frame to the new shape.
Sizing a frame using the frame dialog
More control is available in the frames dialog, where you can set the height and width exactly or set them to be automatic.
Click in a frame to make it active.
Right-click and select the Frames command from the shortcut menu (or select the Frames and Callouts command from the Format menu).
Width - since the Width Type is set at Exactly, set the width you want in the Width box.
Height - choose from:
Auto. The frame will grow and shrink vertically to match the amount of text within the frame. With this setting the dimension in the Height box is ignored.
At Least. The frame will grow vertically to match the amount of text but will not shrink if the text is reduced. You can optionally enter a value in the Height box - note this cannot be set to less than the current value.
Exactly. The height is fixed at the dimension you enter in the Height box.
