Type Chart & Effectiveness

Introduction

Type effectiveness forms the foundation of Pokémon battle strategy. The type chart establishes damage multipliers based on the attacking move's type versus the defending Pokémon's type(s). Generation III has 17 types - Fairy wasn't introduced until Generation VI.

Type Effectiveness Chart

The chart below displays damage multipliers for attacking type (rows) versus defending type (columns). Desktop view presents the full matrix; mobile view enables targeted type selection.

Green (2×): Super Effective - Double damage

Red (0.5×): Resisted - Half damage

Gray (0×): Immune - No damage

White (1×): Neutral - Standard damage

Dual-type Pokémon multiply effectiveness values. A Ground-type move against a Flying/Water Pokémon calculates as 2× (Water) × 0× (Flying immunity) = 0× total - immunities always override weaknesses. Conversely, Ice versus a Dragon/Ground Pokémon yields 2× × 2× = 4× damage.

STAB Bonus

STAB (Same Type Attack Bonus) applies as a 1.5× damage multiplier and stacks multiplicatively with type effectiveness.

Calculation example:

• Torchic, a Fire type, using Flamethrower (Fire): 95 base power × 1.5 STAB = 142.5 effective power
• That Flamethrower against a Grass-type: 142.5 × 2× (super effective) = 285 effective power
• Torchic using a Ground move: no STAB - Ground doesn't match Torchic's Fire typing

Prioritize STAB moves in offensive movesets, and check the type matchups for each Pokémon when building a team.
