Ask HN: What font-size do you prefer on mobile devices?

Do you prefer something like https://agilewombat.com/2016/02/01/scala-vs-kotlin/ or https://sakibsaikia.github.io/2016/12/26/Screen-Space-Reflection-in-Killing-Floor-2.html or (serif) https://www.theguardian.com/film/2017/feb/27/oscars-host-jimmy-kimmel-donald-trump-in-opening-monologue-academy-awards-2017 or (serif) https://shipilev.net/blog/2016/close-encounters-of-jmm-kind/ for lengthier texts? Most of the shit I write is really long and I want to provide a comfortable reading experience.
