🔍 What Is the Pokémon Type Weakness Calculator?
The Pokémon Type Weakness Calculator is a tool designed to determine how different attack types interact with a Pokémon’s defensive typing. This includes:
- Single or dual-type combinations
- Immunities from special abilities like Levitate or Flash Fire
- Detailed results showing weaknesses, resistances, immunities, and normal effectiveness

❓ Frequently Asked Questions (FAQs)
1. What does “4× weakness” mean?
It means the Pokémon takes four times the normal damage from that attack type due to both its types being weak to it.
2. Can I use this tool for any generation?
Yes, the type interactions are based on the standard type chart, which is consistent across modern generations.
3. What if I don’t know the Pokémon’s ability?
You can leave the ability field blank. The tool will assume no ability-based immunity is applied.
4. Does the tool include offensive effectiveness?
No, it only analyzes defensive type matchups (how much damage the Pokémon receives).
5. What is “Wonder Guard”?
Wonder Guard makes the Pokémon immune to all damage unless the move is super effective.
6. Can the calculator detect ability conflicts?
It won’t flag illegal combinations—it’s up to the user to input valid data.
7. How accurate is the defensive rating?
The rating is a general guideline based on the number and severity of weaknesses vs resistances and immunities.
8. Can this be used in competitive team building?
Absolutely! It’s ideal for analyzing synergy and covering team weaknesses.
9. What does “Normal Damage” mean?
It indicates types that deal standard 1× damage—neither resisted nor super effective.
10. Are immunities only based on abilities?
No. Type-based immunities (like Ghost vs Normal) are also included, and abilities add to that.
11. Can I input unofficial or fan-made types?
No, only the standard 18 Pokémon types are supported.
12. How are abilities like “Thick Fat” handled?
The tool reduces Fire and Ice damage by half when “Thick Fat” is selected.
13. What if I enter the same type for primary and secondary?
The tool will alert you and prevent the calculation.
14. Is this optimized for mobile use?
Yes, the tool is designed to work across mobile, tablet, and desktop browsers.
15. How are dual types calculated?
The tool multiplies the effectiveness of each attacking type against both defensive types.
16. Why do some weaknesses become 4x?
If both types are weak to the same attack type (e.g., both Grass and Bug weak to Fire), the multiplier becomes 4x.
17. What’s the best defensive typing?
Combinations like Steel/Fairy or Dragon/Fairy with beneficial abilities often rank high in defense.
18. Are these results valid in competitive battling formats like VGC or Smogon?
Yes, the core type mechanics are the same, though additional factors like held items and abilities may further influence outcomes.
19. Can I export the results?
Currently, results are shown on-screen but can be copied manually for note-taking or planning.
20. Will new abilities be added in the future?
Yes, updates may include more abilities depending on community feedback and generation changes.
