I am using the Beamer metropolis theme, and I would like to change the math font to the default sans-serif font in Beamer presentations, while keeping the text font to be Fira Sans. Is there a simple way to do so (preferably in PDFLaTeX over XeLaTeX)?

I have tried similar approaches as here and here, but neither seems to work for me...

  • Maybe you could also try this one : here.

  • Welcome to TeX.SE! It would be helpful if you provided some code to show explicitly what you've tried so far.

For the use with pdflatex:


\usetheme{moloch}% modern fork of the metropolis theme




x^2 abc



enter image description here

(I don't recommend mixing font families like this)

  • Thanks! It seems that the bold-face Fira fonts (e.g., in the frame titles) are not rendered correctly in pdfLaTeX (seems double-thick...)? Is there a way around this?
