How to read the result
Every move has a type, and each type is more or less effective against the others. A super effective move deals twice the damage (×2). A not very effective move deals half (×½). Against some types it has no effect (×0): a Normal move on a Ghost Pokémon, a Ground move on a Flying Pokémon.
With two types, the multipliers multiply each other. Tyranitar is Rock and Dark: a Fighting move is super effective against both of its types, so ×2 × ×2 = ×4. Conversely, Charizard (Fire and Flying) resists Grass moves twice and takes them at only ×¼. An immunity always wins: a Flying Pokémon takes nothing from a Ground move, even if its second type is weak to it.
What the calculation doesn't see
- Abilities. Several abilities add an immunity or reduce damage from a type:
- Levitate grants immunity to Ground;
- Water Absorb, Volt Absorb, Flash Fire, Sap Sipper, Lightning Rod, Storm Drain and Motor Drive nullify a type and give a bonus in return;
- Thick Fat halves Fire and Ice damage;
- Dry Skin heals from Water but makes Fire worse.
- Terastallization (Scarlet and Violet): a Terastallized Pokémon keeps only its Tera Type on defense.
- Older generations. The Fairy type has only existed since Pokémon X and Y, and the chart in Red, Blue and Yellow was different.
- Pokémon GO uses the same type matchups, but with different multipliers: ×1.6 instead of ×2, ×0.625 instead of ×½, and ×0.39 instead of immunity.

Frequently asked questions
How do I find a Pokémon's weakness?
Type its name or number in the field above: the calculator immediately shows the types that deal ×4 and ×2 to it, the ones it resists and the ones that do nothing to it. The same information appears in the "Type effectiveness" box on every Pokédex page.
What does a ×4 weakness mean?
Both of the Pokémon's types are weak to the same type of move: damage is multiplied by four. That's the case for Ice against Dragonite or Garchomp (Dragon and Flying, Dragon and Ground), or Fighting against Tyranitar. A single move of that type is often enough to knock them out.
Are regional forms and Mega Evolutions taken into account?
Yes. Alolan Vulpix (Ice), Alolan Ninetales (Ice and Fairy), Mega Charizard X (Fire and Dragon) and every form that changes type have their own entry: type the Pokémon's name and choose the form from the list.
What about offense?
Under the weaknesses, the calculator shows which types the Pokémon's same-type moves are super effective against. These are the moves that benefit from the 50% same-type attack bonus. For a whole team, use team coverage.
