What is the Pokemon type chart?

The Pokemon type chart is an 18×18 matrix showing damage multipliers between all attacking and defending types. It determines whether a move deals 2× (super effective), ½× (not very effective), 0× (immune), or 1× (neutral) damage.

When was the type chart last updated?

The type chart was last changed in Generation VI (2013) when Fairy type was added and Steel lost its Ghost and Dark resistances. The chart has remained the same from Gen VI through Gen IX.

How does the type chart work for dual-type Pokemon?

For dual-type Pokemon, multiply the effectiveness values of both types. A 2× weakness from one type combined with another 2× weakness equals 4× total damage. An immunity (0×) always cancels any other effectiveness, resulting in no damage.

What is STAB in Pokemon?

STAB (Same-Type Attack Bonus) is a 1.5× damage multiplier applied when a Pokemon uses a move that matches one of its own types. For example, a Fire-type Pokemon using Flamethrower (a Fire move) deals 1.5× more damage than a non-Fire Pokemon using the same move.

Which Pokemon type has the most immunities?

Ghost and Normal types each have two immunities. Normal is immune to Ghost moves, Ghost is immune to Normal and Fighting moves. Ground is immune to Electric. Steel, Dark, Fairy, and Flying each have one immunity. No type has more than two immunities.

What is a 4x weakness in Pokemon?

A 4× weakness occurs when a dual-type Pokemon is weak to the same attacking type through both of its types. For example, Charizard (Fire/Flying) takes 4× damage from Rock moves because both Fire and Flying are weak to Rock. This is the maximum damage multiplier from type effectiveness alone.

Do abilities affect type effectiveness?

Some abilities alter type interactions: Levitate grants Ground immunity, Thick Fat halves Fire and Ice damage, and abilities like Protean and Libero change the Pokemon's own type. Terastallization in Gen IX can also change a Pokemon's type, altering its weaknesses and STAB coverage.

How to Read the Type Chart

The type chart is a 18×18 matrix where rows represent the attacking type and columns represent the defending type. Find the attacker in the left column, then follow the row to the defending type to see the damage multiplier.

Damage Multipliers

2× – super effective: the move deals double damage to that type
½× – not very effective: the move deals half damage (resisted)
0× – no effect: the defender is immune to that type entirely
1× – neutral: no bonus or penalty

Dual-Type Interactions

For dual-type Pokemon, multiply the effectiveness from both types together. A move that's 2× against one type and 2× against the second deals 4× total. A 2× weakness can be cancelled by a ½× resistance, resulting in 1× neutral damage. Immunities (0×) always override everything – even a 4× weakness becomes 0 if one type is immune.

Generation History

This chart reflects the type system from Generation VI onward, when the Fairy type was introduced and Steel lost its resistances to Ghost and Dark. Prior to Gen II, there was no Steel or Dark type. The chart has remained unchanged from Gen VI through Gen IX.
