Any ideas on how to get this size quicker? Is there any way that has escaped my attention that can return the biggest font size such that the particular string does not exceed a given bounding rectangle? Or should I just fall back to binary search of a certain interval of font sizes? Maybe caching the the size of a representative character in every size and getting a very good first guess for the required font size (particularly if the font is fixed width)? Any ideas or suggestions?

You should be able to do better than binary search with linear extrapolation.
