I don't wanted to say, that you are not right, but the Textstyle $abc$ and the Displaystyle $$abc$$ have the same size for the "baseline". It's another question in what style super/subscripts, fractions, ... are set. Therefore the mathSTYLES have a corresponding fontSIZE. And for the users, who are not so familiar with latex, it's better to say size than style. anyway, it's not worth it to have a longer thread about this stuff. Herbert -- http://www.lyx.org/help/
