To fit a dimension within the text box, right-click the note and open the Autofit drop-down menu. Choose one of the following options:

Do not autofit: The text box adjusts to the size of the text and grows as you type. There is no blank space around the note and making the text larger or smaller adjusts the box accordingly.
Resize text height on overflow: The text always fits the width of the box. If you make the box wider, text from the second line will move up to the first line.
Shrink text on overflow: The text adjusts uniformly (width and height) and scales to fit in the text box.
Shrink text horizontally on overflow: The width of the text changes but the height remains the same.
