About PokéSize Up

Pokémon come in every size, from a 0.1 m Flabébé to a 20 m Eternatus — but side by side on a screen they all look about the same. PokéSize Up puts them back to scale and asks how well you really know them.

Where the data comes from

Every height is the official Pokédex height, taken from PokéAPI. The sprites are PokéAPI's front sprites; each one is measured pixel by pixel so the visible Pokémon — not the empty space around it — matches its official height. Pokémon names in each language are their official ones, also from PokéAPI. The game currently has 386 Pokémon, with more regions on the way;The game currently has 493 Pokémon, with more regions on the way; see them all in the Pokémon height chart.
