IMO, this one suits the upper limit of Type 1: being smaller than any known adult human describes it pretty well.
As for Type 0, I believe the upper limit should be eventually increased upto 147 cm (as pointed out by you), but in case if the majority considers this change way too broad to apply for now, I'm fine with 122 cm, which is the average height of small humans.
Type 9 doesn't really suit this power well, as being one- or two-dimensional doesn't make you automatically smaller than a quantum and the Planck length (either in length or in length and width). Lower-Dimensionality should be its own thing. If I made the page, I'd use two separate types instead:
Type 9 (Sub-Quantum): Characters who are significantly tinier than the Planck length. These characters are so small that they perceive elementary particles as large as humans perceive the Universe.
Type 10 (Infinitesimal): Characters whose size is immeasurably small or infinitesimal.
