If you want to specify both the height and the width without one changing the other, click the small link icon to the left of the Width and Height blanks to unlink the two measurements.Unless you change the default settings, typing a new dimension for Width will automatically update the Height measurement to keep the proportions correct. Type the new dimensions into the Width and Height boxes.
