Hi,
I have two sites using the generate press and in both cases, I am using the typography options as same, but if you will have a look for mrvyasidea.com site content font is large enough and spacious as I expected where I set the font size to 20px and Georgia sheriff and heading as Helvetica
but my other site bloggingos.com with the same font setup seems not taking the large font size and the font looks 14px.
What makes this issue please take a reference of this post https://bloggingos.com/bounce-rate-vs-exit-rate.html
Well just to note, in WP Editor window I selected Georgia Sherrif with 14pt
