Collins Cobuild English Usage says “For example, instead of saying ‘She isn’t taller than her sister’ , you say 'She is [color=red]no taller than her sister.”(p.435)
I had wondered if the presence of “any” might affect the reading of the whole sentence, or if “no taller” may be ambiguous.

In Japan, we learn ‘She is no taller than her sister’ means ‘She is exactly as tall as her sister’ and if ‘her sister’ is known to be actually small, then we can say ‘She is as small as her sister.’ I don’t know who first said something like this, but this is the very understanding we are expected to ‘acquire.’ :?
Yes, I think I’d agree. We hear “she’s no bigger than a mouse”, metaphorically meaning she’s small, but also meaning, metaphorically too, she the same size as a mouse.
