So this is something that's bothered me for a while.
If I'm trying to create a cross-platform scaling solution, I really want it to take into account pixel density. If everything is scaled up uniformly that isn't a problem, but usually you wouldn't want the button size on mobile to scale up proportionally on larger displays.
Ideally I'd be able to do this:
Width * (96/PPI)
Or something similar so that the real-world size of the width was consistent across devices with different pixel densities.
Has anyone looked at this before?
