Screen Size Doesn’t Change

Q: Why doesn’t the terminal screen size change when I make HTPE full screen?
A: The HTPE terminal screen size is determined by the size of the font you are using. It will size itself to display 24 lines of 80 (or 132)
characters of whatever font you’ve selected. If you want a larger terminal screen select a larger font. If you want a smaller terminal screen, select a smaller font size.

You may need to experiment with font selection and size to determine the best choice for readability.
