Pokémon Type Effectiveness Guide
This interactive Pokémon type chart covers all 18 types introduced across Generations I–VI and shows every defensive matchup in a single 18×18 matrix. Select any Pokémon or type combination to instantly see which attack types deal super effective, neutral, resisted, or immune damage: no guessing required.
Damage multipliers explained
Every Pokémon type interaction produces one of five damage multipliers:
- 4× (quad effective): both defending types are weak to the attacker. Example: Charizard (Fire/Flying) vs. Rock.
- 2× (super effective): one type is weak, the other is neutral. The most common winning scenario in competitive play.
- 1× (neutral): no advantage or disadvantage.
- 0.5× (not very effective): one type resists the attacker.
- 0.25× (quad resisted): both types resist the attacker. Example: Magneton (Electric/Steel) vs. Electric.
- 0× (immune): one type has a full immunity. Overrides all other multipliers.
When a Pokémon has two types, the multipliers are multiplied together. A 2× × 2× becomes a 4× weakness; a 0.5× × 0.5× becomes a 0.25× resistance.
Type immunities
There are 8 attack-and-defense type immunity pairs in the current generation: Ghost is immune to Normal and Fighting; Normal and Ground are immune to Ghost and Electric respectively; Flying is immune to Ground; Dark is immune to Psychic; Steel is immune to Poison; and Fairy is immune to Dragon. When one of a dual-type Pokémon's types grants immunity, it reduces the multiplier to 0 regardless of the second type: even if the second type has a 4× weakness.
Base-type comparison
In the base chart, Steel has 10 resistances, 1 immunity, and 3 weaknesses (Fire, Fighting, Ground). Rock has 5 weaknesses and 3 resistances. These counts are exact type facts. They are not a competitive recommendation because abilities, stats, moves, items, and format context also matter. The base chart was checked against Pokémon Showdown type data on 2026-08-15.
Frequently asked questions
- What type has the most weaknesses?
- Rock has 5 weaknesses as a single type (Water, Grass, Fighting, Ground, Steel). As a dual type, Grass/Ice and Rock/Ice each have 7 weaknesses: the highest in the game.
- Which type has no weaknesses?
- No single base type has zero weaknesses. Normal is weak to Fighting and Electric is weak to Ground. Eelektross shows a Ground weakness here because the calculator does not apply Levitate.
- What is the best offensive type?
- The chart does not define one best offensive type. Ground hits Fire, Electric, Poison, Rock, and Steel super effectively. Bug and Grass resist it, and Flying is immune. Ability effects such as Levitate are not included.
- When was Fairy type added?
- Fairy was introduced in Generation VI (Pokémon X and Y, 2013). It was added primarily to counter Dragon and Dark types, which had few counters in previous generations.
How to use this type chart
Click any type pill to filter the defensive calculator. Click a second type to see a dual-type breakdown. Use the Pokémon search bar to auto-fill both types for any Pokémon. The full 18×18 matrix at the bottom shows attacking types as rows and defending types as columns: hover any cell to highlight the row and column. Use this Pokémon weakness calculator to compare base-type coverage. It does not select the best move because damage also depends on the move, stats, abilities, items, weather, and battle state.
