Excellent article. It took me several doubts that I had. I trying more and more implement the 8pt grid on my workflow. I'm reading a lot and still trying to find the best layout grid size and type scale to work with the 4pt baseline. I'm using 1024 total width (16gt 114cl) and i'm trying to find an ratio for the type scale (most of them have has a lot of odd number for the line height like 16pt and 21 leading. Would be awesome if you could show us your grid and your typescale. Or if you have an sketch file with those specifications or an article I would be very grateful.
