Pokémon Type Calculator

Find Pokémon Type Strengths, Weaknesses, Resistances, and Immunities

A Pokémon Type Calculator shows how much damage each of the 18 attacking types deals to a Pokémon. Search a Pokémon by name or pick up to two types and you instantly see its 4× and 2× weaknesses, ½× and ¼× resistances and 0× immunities, based on the type chart used from Gen 6 (X and Y) through Scarlet and Violet.

Whether you are building a competitive team, choosing the best move for a battle, or simply checking a type matchup, this Pokémon calculator gives you the information you need in seconds.

How the Pokémon Type Calculator Works

The calculator uses the official type chart from the current games (Gen 6 to Gen 9) and multiplies the effect of each defending type together. Here is how to use it in three quick steps.

1. Search a Pokémon or pick its types

   Type any Pokémon name, including Mega, Alolan, Galarian, Hisuian and Paldean forms, or tap one or two type buttons. Results appear instantly, with no extra button to press.

   

2. Read the weaknesses, resistances and immunities

   Every attacking type is grouped by its damage multiplier: 4× and 2× weaknesses, normal damage, ½× and ¼× resistances, and 0× immunities. You also see which types the Pokémon hits super effectively with its own STAB moves.

   

   Open Advanced options to change the generation, apply a Tera Type, add an ability such as Levitate or Flash Fire, add a third type, or switch to Inverse Battle rules.

3. Check your whole team

   In Team Builder, add up to six Pokémon. The table shows how every attacking type hits each team member, and the calculator highlights shared weaknesses and team holes that no member resists.

   

Use the Offense / Coverage tab when you want to know what a move type is super effective against, or the exact multiplier against a specific Pokémon.

Pokémon Type Matchups by the Numbers

There are 18 types, so the type chart has 18 × 18 = 324 single-type matchups. In the current games they break down like this:

• Steel is the best defensive type. It resists 10 attacking types and is immune to Poison.
• Grass and Rock have the most weaknesses, with five each.
• Electric and Normal have only one weakness each: Ground for Electric and Fighting for Normal.
• Fighting and Ground hit the most types super effectively (five each). Normal is not super effective against anything, and Dragon is only super effective against Dragon.
• Dual types multiply. There are 153 possible type pairs. More than 140 of them appear in the games, and about one in three of those has at least one 4× weakness.

Pokémon Type Strengths and Weaknesses

Understanding type strengths and weaknesses is one of the most important parts of Pokémon battles.

A type advantage can help you deal significantly more damage, while a resistance can reduce incoming damage. Some Pokémon types can also completely ignore certain attacks because of their type immunities.

Instead of memorizing the entire type chart, use the calculator to quickly check the matchup you need.

Complete Pokémon Type Chart

This table shows how every type defends in the current games (Gen 6 to Gen 9). Use it as a quick reference, then use the calculator above for dual-type Pokémon, where the two types multiply together.

Pokémon Type Weakness Guides

Pick a type to learn what it is weak to, what it resists and which dual types are the most fragile. Every type has a full guide with its weaknesses, resistances, 4× dual-type combinations, best counters and a printable chart. You can also compare them all on the Pokémon type weaknesses overview.

Popular Pokémon With a 4× Weakness

When both of a Pokémon’s types are weak to the same attack, the damage is multiplied twice and the Pokémon takes 4× damage. These well-known Pokémon all have one, so a single super effective move can knock them out:

Ice is the most common 4× threat in this list, because Dragon/Flying and Dragon/Ground Pokémon are both weak to it twice over. Tap any name to load it in the calculator.

How the Type Chart Changed Across Generations

The type chart has been updated twice, so older games use slightly different rules:

• Gen 1 (Red, Blue and Yellow): only 15 types, with no Dark, Steel or Fairy. Bug and Poison were super effective against each other, Fire did not resist Ice, and Ghost moves had no effect on Psychic Pokémon.
• Gen 2 to Gen 5 (Gold and Silver to Black 2 and White 2): Dark and Steel were added. Ghost became super effective against Psychic, and Steel also resisted Ghost and Dark moves.
• Gen 6 onward (X and Y to Scarlet and Violet): Fairy was added as the 18th type, and Steel lost its resistance to Ghost and Dark.

Playing an older game? Open Advanced options in the calculator and switch to Gen 1 or Gen 2–5.
