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.

Made by JhonaMath

PokéSize Up is made by JhonaMath, who also makes Pokennection and Critter Loop. It's free to play, with no download and no account needed.

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. The game currently has 151 Pokémon, with more regions on the way; see them all in the Pokémon height chart.
