Type chart

A type chart shows which modifiers are applied to move types when attacking of each type. Please note that this only covers single types, not pairs. To get a dual-type Pokémon's matchup against a specific move type, go across the table's columns to each of the types, see what the effectiveness of the move is against both, and multiply the effectiveness together: in this way a move would hit for 4× damage on a Bug/Grass-type Pokémon, while a  move used against the same would do only a quarter of its normal damage. The type chart differs depending on the generation of it is from.
