Hi Susan
We don't provide the ability to change the title font height. You can change the appearance of the title and subtitle, such as whether they have a background, and you can also change the font family that is used, via the Settings > Apppearance dialog. But we keep the font size fixed to give all Cascades a uniform look and feel. We also scale that font size based on the display that is being used. Is your title simply too long to fit? If so, we'd recommend using a shorter title. Or if something else is going on, could you paste a screenshot graphic here for us to see?
