Best font size for both desktop and mobile users

Hi sallen0907​!

Great question!

For Rise 360 courses, 16–18px for body text is right in the recommended range, especially when most learners will be on mobile. Also, Rise is fully responsive, so text doesn’t just shrink on smaller screens but reflows to adapt. Because of that, 16–18px reads comfortably on phones, even if it can feel a bit smaller on desktop at first glance. On larger screens, there’s more white space and wider line length, which can make text appear smaller even while legible.

As you mentioned, desktop users also have the flexibility to zoom their browsers if necessary. It makes sense to prioritize the mobile experience when the majority of learners are accessing the course that way.

I'll also open the floor to our community to share their design suggestions with you!
