HeightDex

The HeightDex groups Pokémon into five groups: each group's height range is essentially chosen on an arbitrary basis where some consideration was given to the amount of Pokémon falling within a given height range.

Tiny 0.1 - 0.4 meters	Short 0.5 - 0.9 meters	Average 1.0 - 1.4 meters	Tall 1.5 - 1.9 meters	Giant 2+ meters
