Pokémon Weakness Calculator
Enter a Pokémon's one or two types to see all 18 attacking types sorted by what they do to it -- weaknesses, resistances, immunities and neutral matchups, in one view.

How it's calculated
For each of the 18 attacking types, the calculator multiplies its effect against your first type by its effect against your second type (or just uses the single value for a mono-type Pokémon), then groups the 18 results by the outcome:
weak to = count(multiplier ≥ 2) · resists = count(0 < multiplier < 1) · immune to = count(multiplier = 0)
Worked example
Water/Ground -- Swampert's typing, and one of the best-known defensive typings in the games:
Weak to
1
Grass, at 4x
Resists
4
Fire, Poison, Rock, Steel
Immune to
1
Electric
Neutral
12
the rest
A single real weakness (Grass, and it hits for 4x), a full immunity to Electric, and four resistances -- which is exactly why Water/Ground is a famously strong defensive typing. Plug the same two types into the calculator above and it lands on the same breakdown.

Frequently Asked Questions
How is a Pokémon's weakness count worked out?
Every one of the 18 attacking types is checked against the typing you enter, and grouped by the resulting multiplier. "Weak to" counts every attacking type at 2x or 4x; "resists" counts ½x and ¼x; "immune to" counts 0x; everything else is neutral.
Why does a dual type sometimes have fewer weaknesses than a single type?
Because the two types' effects stack by multiplication, not addition -- a type that's 2x against one of the pair and ½x against the other cancels out to a neutral 1x, and a type that's ½x against both stacks down to a full ¼x resistance. A second type can cancel out a first type's weaknesses as easily as it can add new ones.
What's a "4x weakness," specifically?
It's when a single attacking type is super effective (2x) against both of a dual-type Pokémon's types at once, so the two 2x multipliers stack to 4x -- quadruple damage from one move. It's the most dangerous matchup a dual type can have, and it shows up separately from an ordinary 2x weakness in the breakdown above.
Where can I compare this typing against every other one?
The dual-type calculator ranks all 171 possible typings side by side by weakness count, resistance count and a combined defensive score, so you can see exactly how this one stacks up.
