I tried it but with 2 different resolutions I still had my problem, the size did not fit. However, when I was resizing my page manually the font size was changing so the dynamic is working in a way.
But I found a solution that it seems to solve my problem.
I wrote a little script for fontSize property, and the font size is now adapting to the resolution and the size of the view based on the width of the page:
The formula is simple, for a width of 1920 I want a size of 20px, so I use this ratio to calculate the font size.
Thanks for your help!
