In Short: I can change the math font, but it is not working for numbers.

My document has a few formulae but only basic alphanumeric characters with very limited symbols (square root being the only particular character outside of the most common)

I have looked at the following questions:

And have gotten this far using the mathastext package (I'm on v1.3w):

enter image description here

I have made sure to load mathastext after fontspec.

But, while letters show as expected, numbers still have serifs.


  • I am compiling with LuaLatex due to other packages in the mix


    \center{Body Text}

You have to load fontspec with the no-math option.

%    Path=fonts/,
%    Extension=.ttf
\setmainfont{Impact} % a random distinctive font on my system



\begin{center}Body Text\end{center}


By the way, the command \center exists but

  • it has no argument
  • it should only be used implicitly via the center environment

enter image description here

  • Thank you, this worked perfectly. The \center was just to create the sample image, I should have removed it from my MWE, apologies for any confusion it may have caused.

You could also load


And set the fonts to something like (if you’ve added a Rubik.fontspec file to your project directory):

\defaultfontfeatures{ Scale=MatchUppercase, Ligatures=TeX }
\setmathfont{Fira Math}

You can add to this any other characters the Rubik font contains, either with a hex code like "FF, a macro name, or a backtick literal. You can also do ranges, so if the font supports all of Latin-1, you could write range={up,"20-"FF}.

If the font you select does not have Greek letters, use instead:

  • I have seen "fone" into your answer and after I have understood that the word is font 😄

  • Nice, if I understand correctly, this would give me total granularity to have a specific character or set of characters in a specific font for formulae ? (That's much more than I need for this specific case but a nice tool to keep in the bag for later. - Thanks!)

  • @agryson Yes. You can also apply any other transformation from fontspec, such as changing their color.
