[[File:Sylveon vs Hydreigon.png|200px|thumb|{{p|Sylveon}} using a super-effective move on {{p|Hydreigon}}]]

* If the type of a move is '''super effective''' (Japanese: '''{{tt|効果はバツグン|こうかはばつぐん}}''' ''super effective'') against a type of its target, the damage done is double the normal amount;

* If the type of a move is '''not very effective''' (Japanese: '''{{tt|効果は今一つ|こうかはいまひとつ}}''' ''not very effective'') against a type of its target, the damage done is half the normal amount;

* If the type of a move is super effective against one of the opponent's types but not very effective against the other (such as {{m|Razor Leaf}}, a {{type|Grass}} move, used against a {{p|Gyarados}}, a {{2t|Water|Flying}} Pokémon), then the move deals normal damage;

The moves {{m|Flying Press}}, {{m|Freeze-Dry}}, and {{m|Thousand Arrows}} have custom interactions with defending types and do not strictly obey the type chart. {{type|Fire}} moves double in effectiveness against Pokémon affected by {{m|Tar Shot}}. {{cat|Moves that deal direct damage}} (including [[one-hit knockout move]]s) do not employ effectiveness, although Pokémon may still be immune to them based on type interactions. Certain {{Abilities}}, [[held item]]s, or types of [[weather]] (such as {{a|Levitate}}, the [[Ring Target]], or [[strong winds]], respectively) may modify the effectiveness of specific types of moves.

[[Status move]]s typically do not employ type effectiveness; however, {{type|Ground}} Pokémon are immune to {{m|Thunder Wave}} based on type interactions, and {{type|Ghost}} Pokémon are immune to {{m|Glare}} based on type interactions in Generation II and III only. Furthermore, status moves may be unable to affect Pokémon based on type-related interactions other than effectiveness; for example, {{type|Poison}} Pokémon cannot be afflicted with {{status|poison}} and are thus unaffected by {{m|Poison Gas}}.

A '''type chart''', also known as '''type matchup chart''', shows which modifiers are applied to [[move]] types when attacking {{OBP|Pokémon|species}} of each type. If the defending Pokémon is dual-typed, the modifier is calculated as the product of the modifiers for both of its types: a {{type|Flying}} move would hit for 4× damage on a {{2t|Bug|Grass}} Pokémon, while a {{type|Ground}} move used against the same would do only a quarter of the normal damage. (A complete ineffectiveness against either type will make the move deal no damage, since 0 multiplied by any number is 0.)

In [[Inverse Battle]]s, a different type chart is used that essentially inverts the normal type chart, turning immunities and resistances into weaknesses, and weaknesses into resistances.

Some types of field effects, {{Abilities}}, and [[held item]]s affect moves of a certain type. {{m|Sunny Day}}, for example, causes {{type|Fire}} moves to increase in power, while {{a|Levitate}} causes {{type|Ground}} moves to not work on the Pokémon with this Ability. Likewise, each type has a [[Type-enhancing item|specific held item]] that can be given to a Pokémon that will power up one of the specific types by 20% (or 10%, prior to Generation IV), such as the [[Metal Coat]] for {{type|Steel}} moves.  

{{cat|moves that change a Pokémon's type|Some moves}} can change the type of a Pokémon. For example, {{m|Camouflage}} changes the user's type to a type corresponding to the battlefield terrain. Abilities can also change the type of a Pokémon. These abilities include {{a|Color Change}}, {{a|Multitype}}, {{a|Protean}}, and {{a|RKS System}}.

There are situations where Pokémon or moves behave as if they were typeless, unable to receive {{STAB}} and boosts from [[type-enhancing item]]s or {{cat|type-enhancing Abilities|Abilities}}. Typeless Pokémon take regular damage from all moves, and typeless moves deal regular damage against all Pokémon.

{{m|Struggle}} acts typelessly from [[Generation II]] onward. A pure {{type|Fire}} Pokémon that uses {{m|Burn Up}} becomes typeless. The move {{m|Weather Ball}} acts typelessly under [[shadowy aura]], and the move {{m|Revelation Dance}} acts typelessly if used by a typeless user (in which case it does not receive {{STAB}}).

There are several types which only appear through the use of glitches, such as on the types of [[glitch Pokémon]]. Most famously this includes the {{t|Bird}} type, which was intentionally programmed into the code of the Generation I and II games but was not given to any real Pokémon. Other glitch types are the result of the game reading other data as if it were types. Like the ??? type, all glitch types have no special effectiveness (they both inflict normal damage against all types and take normal damage from all types).

In {{g|GO}}, icons were introduced to represent each of the types during gameplay. Very similar icons were later adopted into the [[core series]], starting with [[Pokémon Sun and Moon]], then [[Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!]], {{g|Sword and Shield}} and {{g|HOME}}.

In the [[Pokémon Mystery Dungeon series]], the type effectiveness chart differs from contemporaneous core series games. Type effectiveness also differs among the series, as does whether effectiveness multipliers stack against dual-typed Pokémon. For example, in [[Pokémon Mystery Dungeon: Red Rescue Team and Blue Rescue Team]], moves that are ineffective in the core series deal ½× damage instead, not very effective moves deal 0.7× damage instead, and multipliers stack against dual-typed Pokémon. In [[Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness|Explorers of Time and Explorers of Darkness]], moves that are ineffective in the core series deal ¼× damage, and multipliers typically do not stack. In [[Pokémon Super Mystery Dungeon]], moves that are ineffective in the core series are ineffective as well (0× damage).

In [[Pokémon GO]], type effectiveness multipliers differ from the core series games, but using the same type effectiveness chart. Most significantly, an attacking type that would be ineffective against a defending type in the core series is instead doubly resisted.  

The multipliers in Pokémon GO are based on 1.6 (1.4 prior to December 12, 2018 and 1.25 prior to June 21, 2017). If a move is super effective, its damage is multiplied by 1.6; if it is resisted, its damage is divided by 1.6 (multiplied by 0.625); if it is doubly resisted (i.e. corresponds to an immunity in the core series), its damage is divided by 1.6² (multiplied by 0.390625). If multiple of the Pokémon's types are weak to or resist the move's type, the product of the multipliers is used.

The possible effective multipliers are as follows.
