Pokemon Type Chart and Effectiveness Calculator

Pokemon battles revolve around an 18×18 type effectiveness matrix. Every attacking move has a type, and every defending Pokemon has one or two types. The interaction between them produces multipliers of 2× (super effective), 1× (neutral), 0.5× (not very effective), or 0× (immune).

Dual-Type Calculations

When a Pokemon has two types, the game multiplies both matchups together. A Water/Ground type takes 4× damage from Grass (2× against Water times 2× against Ground) but is completely immune to Electric (0× against Ground overrides everything). This creates 0.25× double resistances and 4× double weaknesses that single types never experience.

Coverage Analysis

Select multiple attack types to analyze combined coverage across the entire Pokédex. Factor in special moves like Freeze-Dry (Ice move that hits Water super effectively), Flying Press (dual Fighting/Flying attack), and Thousand Arrows (Ground move that hits Flying types). Abilities like Scrappy and Tinted Lens further modify coverage.
