When battling in Pokémon games, knowing type matchups can change the result of a fight. Every Pokémon can have one or two types, and attacks interact differently with these types. A Pokémon Dual Type Calculator Online helps trainers easily calculate damage multipliers when attacking or defending.
For example, a move like Thunderbolt (Electric) will deal 2× damage to Water-types, but if the opponent is Water/Flying, the multiplier becomes even higher (4× damage). On the other hand, Electric attacks deal 0× damage to Ground-types.

🔹 Formula for Damage Multiplier
When calculating dual-type effectiveness, the formula is:
Total Multiplier=Effectiveness vs Type 1×Effectiveness vs Type 2\text{Total Multiplier} = \text{Effectiveness vs Type 1} \times \text{Effectiveness vs Type 2}Total Multiplier=Effectiveness vs Type 1×Effectiveness vs Type 2
- Super Effective = 2×
- Not Very Effective = 0.5×
- No Effect = 0×
- Neutral = 1×
👉 Example:
If a move is Ice-type against a Dragon/Flying Pokémon:
- Ice vs Dragon = 2×
- Ice vs Flying = 2×
- Total = 2 × 2 = 4× (quadruple damage)
