The Main Title Size indicator governs the size of all graph titles, not just the main title. As a result, you can set this indicator even if the Main title option has been turned off.
The effectiveness of the Main Title Size indicator depends in part on the length of the text strings to be printed. If the total text string (main and sub-titles) is too long, you may not be able to enlarge the print, even if you set the value to Large.
It is also possible, if the title text is too long, that the Main Title Size indicator works only when the Main title option is turned off. This is because when you turn the option off, you reduce the displayable title to a sub-title only. This shortened string can then be made larger or smaller at will.
