About TypeChart

Updated October 21, 2026

TypeChart is an independent reference tool for Pokémon type matchups, team weaknesses and natures. The tools are free to use without an account.

How calculations work

Type matchups and the Pokédex are built from a pinned Pokémon Showdown data snapshot. The type-rule groups are Generation 1, Generations 2–5, and Generation 6 onward. Team results describe defensive typing; abilities, items and move-specific effects are not simulated.

Sources and corrections
