Re: Target size proposal

I notice on the Google material guidelines page that the text links are 15px tall (I think that on a 96dpi monitor this means 25 CSS px) and I also see this:

Density
When mouse and keyboard are the primary input methods, button measurements can be slightly reduced to accommodate dense UIs. (32dpi in height) 

Also, in the size and padding section, the material guidelines indicate that the button can be 36dp inside the 48dp target, so leaving 6dp on each side.

Thanks,

    Also worth pointing out (as already pointed out on various occasions in the past) that whether you look at Microsoft, Google, or Apple, guidance on target sizes is advisory - usually couched in terms like "in general", "should", "avoid", and so on - and that these companies themselves sometimes break their own guidance when deemed appropriate (a classic example with Apple, for instance, would be the minuscule "Back" 
    control in the phone's top bar when you, say, follow a link in an email and it opens Safari). Meaning these are more subtle than hard pass/fail values set in stone, and more of good practice / UX guidance.
