Pokemon Type Coverage Calculator

Select the types for each Pokémon on your team (up to 6). This tool will analyze your team’s offensive strengths and defensive weaknesses against all 18 Pokémon types.

What is a Pokémon Type Coverage Calculator?

A pokemon type coverage calculator is an essential tool for competitive Pokémon players and team builders. It analyzes the types of the Pokémon on your team to provide a clear picture of your overall offensive strengths and defensive vulnerabilities. In Pokémon battles, type matchups are everything. An attack can be super effective (2x damage), normal (1x damage), not very effective (0.5x damage), or have no effect at all (0x damage). This calculator automates the complex process of cross-referencing every Pokémon type on your team against all 18 official types.

By using this tool, you can quickly identify “coverage gaps”—types that your team’s attacks don’t hit super effectively—and critical defensive weaknesses that a savvy opponent could exploit. The goal is to build a balanced team, and that starts with understanding your type synergy. This calculator is designed for anyone from a beginner learning about matchups to a seasoned veteran fine-tuning a championship-level team. To learn more about the basics, check out our guide on competitive pokemon strategy.

Pokémon Type Coverage Formula and Explanation

The “formula” for a pokemon type coverage calculator isn’t a single mathematical equation, but a system of logical lookups based on the official Pokémon Type Chart. The calculator processes two main aspects: offense and defense.

Offensive Calculation Logic

For each of the 18 types in the game (Normal, Fire, etc.), the calculator checks the highest damage multiplier your team can achieve against it. It iterates through each of your Pokémon’s types and finds the maximum effectiveness value.

OffensiveMultiplier(OpponentType) = MAX(Effectiveness(YourType1, OpponentType), Effectiveness(YourType2, OpponentType), ...)

Defensive Calculation Logic

For each of the 18 types, the calculator determines how much damage each of your Pokémon would take from an attack of that type. For a dual-type Pokémon, the multipliers are combined.

DefensiveMultiplier(AttackingType, YourPokemon) = Effectiveness(AttackingType, YourPokemonType1) * Effectiveness(AttackingType, YourPokemonType2)

The calculator then shows you the most significant weaknesses across your entire team.

Variables Table

Variable	Meaning	Unit	Typical Range
Effectiveness	The damage multiplier between two types.	Multiplier (x)	0x, 0.25x, 0.5x, 1x, 2x, 4x
Offensive Coverage	The highest damage multiplier your team can deal to a specific type.	Multiplier (x)	0x, 0.5x, 1x, 2x
Defensive Weakness	A multiplier greater than 1x, indicating your Pokémon takes extra damage.	Multiplier (x)	2x, 4x
Defensive Resistance	A multiplier less than 1x, indicating your Pokémon takes reduced damage.	Multiplier (x)	0.5x, 0.25x, 0x (Immunity)

Practical Examples

Example 1: Classic Fire-Water-Grass Core

A common beginner’s strategy is to use a Fire, Water, and Grass type trio. Let’s see how it looks in our pokemon type coverage calculator.

• Inputs: Pokémon 1: Charizard (Fire/Flying), Pokémon 2: Blastoise (Water), Pokémon 3: Venusaur (Grass/Poison)
• Offensive Results: This core has excellent offensive coverage. Fire hits Grass, Ice, Bug, and Steel. Water hits Fire, Ground, and Rock. Grass hits Water, Ground, and Rock. The combination covers many types super effectively. However, it struggles against Dragon types, as none of these primary types hit it for super-effective damage.
• Defensive Results: The team has a glaring 4x weakness to Electric attacks on Charizard (Flying) and Blastoise (Water). Venusaur is weak to Flying, Fire, Psychic, and Ice. A fast Electric or Psychic attacker poses a significant threat to this team. You might want to pair this with a pokemon damage calculator to see exactly how much damage you’d take.

Example 2: Steel/Dragon/Fairy Defensive Core

Let’s analyze a more advanced defensive pokemon core.

• Inputs: Pokémon 1: Garchomp (Dragon/Ground), Pokémon 2: Metagross (Steel/Psychic)
• Offensive Results: This duo offers powerful offensive pressure. Dragon/Ground STAB from Garchomp is famously effective, only resisted by a few types like Steel and Flying. Metagross’s Steel/Psychic hits Fairy, Rock, Ice, Fighting, and Poison types. The main offensive gap is against Steel/Flying Pokémon like Corviknight.
• Defensive Results: This core is defensively solid. Metagross has 8 resistances and 1 immunity. Garchomp is immune to Electric. However, there’s a shared weakness to Fire and Ground on Metagross. Most critically, Garchomp has a devastating 4x weakness to Ice-type attacks. The calculator would immediately flag this as a critical vulnerability to address.

How to Use This Pokémon Type Coverage Calculator

1. Select Your Team’s Types: For each of your Pokémon (up to six), use the dropdown menus to select their primary and, if applicable, secondary type. If a Pokémon has only one type, leave the second dropdown as “None”.
2. Click Calculate: Press the “Calculate Coverage” button to run the analysis.
3. Review Offensive Coverage: The chart and summary list will show you which of the 18 types your team can hit for super-effective (2x or more) damage. Pay attention to the types in the “Not Covered” list—these are your offensive gaps.
4. Analyze Defensive Weaknesses: The “Defensive Coverage Table” is crucial. It shows you which attack types pose a threat to your team. A value of ‘2’ or ‘4’ indicates a major weakness you need to plan for. Look for shared weaknesses across multiple Pokémon.
5. Refine Your Team: Based on the results, you may want to swap a Pokémon or use a specific pokemon iv calculator to optimize stats. The goal of a good pokemon type coverage calculator is to help you build a more balanced and resilient team.

Key Factors That Affect Pokémon Type Coverage

• Dual Types: A Pokémon’s second type can drastically alter its matchups, adding resistances and weaknesses or even providing a 4x weakness/resistance.
• Abilities: Abilities like Levitate, Flash Fire, or Sap Sipper can grant a Pokémon an immunity or resistance they wouldn’t normally have, which this calculator does not account for. Always consider abilities in your final team-building.
• Move Selection: This calculator analyzes type (STAB) coverage. Your actual moveset (e.g., a Water-type with an Ice-type move) provides much wider coverage. This is a tool for foundational competitive pokemon strategy.
• Team Synergy: Good coverage isn’t just about offense. It’s about how Pokémon cover each other’s weaknesses. A Pokémon weak to Ground can pair well with a Flying-type or one with the Levitate ability.
• The Current Metagame: The most popular and powerful Pokémon in the current competitive environment (the “meta”) determine which offensive and defensive types are most valuable. Coverage that was great last season might be poor today.
• Tera Type (Scarlet & Violet): Terastallization completely changes the game by allowing a Pokémon to temporarily change its type, overriding its defensive weaknesses and changing its offensive STAB. Our calculator focuses on a team’s native typing.

Frequently Asked Questions (FAQ)

1. How many Pokémon can I add to the calculator?

You can analyze a full team of up to six Pokémon to get a complete overview of your team’s type synergy.

2. Does this calculator account for abilities like Levitate?

No, this is a pure type-based calculator. It analyzes the inherent strengths and weaknesses of types themselves. You must manually account for type-altering abilities like Levitate (grants Ground immunity) or Flash Fire (grants Fire immunity and a power boost).

3. What does a 4x weakness mean?

A 4x weakness occurs when a dual-type Pokémon has two types that are both weak to the same attacking type. For example, a Rock/Ground type like Golem is weak to Water (2x) and its Ground typing is also weak to Water (2x), resulting in a combined 4x damage multiplier. These are critical vulnerabilities.

4. Why can’t my team hit a certain type for super-effective damage?

This is called an “offensive gap.” If your results show you don’t have super-effective coverage against, for example, the Dragon type, you should consider adding a Pokémon or a move that is Dragon, Ice, or Fairy type to your team.

5. Is it bad to have overlapping weaknesses?

Generally, yes. If three of your six Pokémon are weak to Fire-type attacks, a single enemy Fire-type Pokémon can cause major problems for your team. A good team structure, using a defensive pokemon core, minimizes shared weaknesses.

6. Does this calculator work for all Pokémon games?

Yes, this calculator uses the type chart that is current as of Pokémon Scarlet and Violet, which includes the Fairy type and the Steel type’s adjusted resistances. It is accurate for all games from Generation 6 (X & Y) onward.

7. What is the difference between type coverage and move coverage?

This pokemon type coverage calculator analyzes the inherent types of your Pokémon. Move coverage refers to the types of the actual four moves a Pokémon knows. A Pokémon can learn moves of types other than its own to cover its weaknesses or hit more opponents super effectively.

8. Where can I find more info on specific Pokémon like Charizard?

For detailed information on a Pokémon’s stats, moves, and abilities, you should consult a full Pokédex resource. Our tool is focused on the team-level synergy of types.
