The only programming language I know of that has a facility like this
(using the language proper, i.e. not asking the operating systems using
some function of the operating system's API or some such)
is PostScript, which has builtin operators for text strings and
bounding box heights of characters and fonts.

Again, where does your text live? Is it a string "in Windows"?
Use a call to the appropriate operating system's library function to find
its dimensions. This is the same in any language.
Are you dealing with a typwriter like printer?
In that case the number of characters should give enough hints.
Do you have to ask a Java Virtual Machine for the dimensions
of specific characters in specific fonts? Etc.
