Long-form Project Note
A closer look at TypeMatchup
TypeMatchup is a free, fan-made Pokémon type reference. Choose a single or dual defensive typing to see 4× weaknesses, standard weaknesses, resistances, quarter-damage matchups, immunities, and neutral types. The site also has guides for all 153 dual-type pairings, Pokémon-specific pages, an 18×18 chart, a Gen 9 calculator, ability-adjusted charts, a quiz, and a battle simulator with STAB calculations.
This note reflects a first-time user perspective.
What caught my eye
Dual typings are where a familiar type chart starts getting easy to misread. TypeMatchup puts the multiplied result first, then explains how it got there. That makes it handy for a quick defensive check. It still covers type effectiveness, not the whole battle. Stats, moves, abilities, items, and format rules can change what happens next.
How TypeMatchup works
Choose one or two defensive types and TypeMatchup sorts the result into weaknesses, resistances, immunities, and neutral matchups. It also shows stacked 4× and 0.25× effects.
Deeper reference pages cover individual types, Pokémon, all 153 dual-type pairings, Gen 9 calculations, ability adjustments, and an 18×18 chart. A quiz and battle simulator add practice and STAB calculations.
Who might find it useful
Players checking a defensive matchup while building a team, preparing for a raid, or planning a Nuzlocke run.
Newer players can use the explanations to learn why a multiplier appears instead of memorizing the full chart.
Closing context
TypeMatchup makes the fiddly part of dual-type math quick to read and easy to trace. Use it as a type reference, then bring the rest of the battle mechanics into the decision.
