Is there some kind of standard symbol size in LaTeX? I am looking to design an icon in the Latex font based on how certain operations or symbols look like in latex. For example the square operation with a "placeholder" (that should be the standard symbol size of latex) as the base and 2 as the exponent.
I know that sizes in Latex are dynamic most of the time but I was still wondering if there maybe is something like this.
I appreciate every answer.
