pokemon weaknesses calculator

What this Pokémon weaknesses calculator does

This calculator helps you evaluate a Pokémon's defensive type profile. In practical terms, that means:

• Which attacking types hit your Pokémon super effectively (2× or 4×)
• Which attacking types your Pokémon resists (0.5× or 0.25×)
• Which attacking types deal no damage at all (0× immunities)

Whether you are building for story mode, ranked singles, VGC doubles, or fan formats, quickly checking weaknesses can save you from accidental team overlap and improve battle consistency.

How to use it

1) Select your type combination

Choose a primary type and, if needed, a secondary type. If your Pokémon is single-typed, leave secondary as None.

2) Click calculate

The tool applies standard type multipliers and groups the results into intuitive buckets:

• 4× Weak — dangerous matchup, often a one-shot risk
• 2× Weak — clear weakness, important to cover
• 0.5× Resistant — useful defensive switch-in targets
• 0.25× Double Resistant — very strong defensive cushion
• 0× Immune — free pivot opportunities

3) Build your team around the output

The best use of a weakness calculator is not just to protect one Pokémon, but to check your entire six-Pokémon core and avoid stacking the same vulnerabilities (for example, three Ground-weak Pokémon with no immunity).

Quick strategic examples

Fire / Flying

A classic case: Fire/Flying gains useful resistances, but suffers a severe 4× weakness to Rock. One Stealth Rock setup can heavily punish repeated switching.

Water / Ground

This combination has an Electric immunity and many useful resistances, but a major 4× weakness to Grass. Teammates that resist Grass are mandatory.

Steel / Fairy

Often a strong defensive typing with lots of resistances and useful dragon/dark checks. This is a good reminder that dual-typing can dramatically flatten matchup risk.

Important limitations to remember

Type charts are foundational, but battles include many extra systems that can change outcomes:

• Abilities: Levitate, Flash Fire, Thick Fat, Dry Skin, etc.
• Held items: Air Balloon, Assault Vest, resistance berries
• Field effects: weather, terrain, hazards, screens
• Terastallization: can completely alter your type profile

So treat this calculator as your first-pass defensive check, then fine-tune around your format and rule set.

Final tip for better team building

After calculating one Pokémon, repeat for every team slot and map common incoming attack types. If you can ensure at least one safe switch into common threats (Ground, Fighting, Fairy, Dragon, Ice, and Water depending on format), your team becomes much harder to break.
