Pokémon Type Coverage Calculator

How to Use Pokémon Type Coverage Calculator

The Pokémon Type Coverage Calculator helps you answer a common team-building question: does this set of attack types hit enough of the type chart, or are there obvious defensive types that still wall the plan? Start by selecting the attack types available to your team or moveset, such as Fire, Water, Ground, Electric, Ice, Fighting, Fairy, or Dark. The right panel updates immediately and shows how many single defensive types can be hit for super effective damage by at least one selected attack type.

Use the selected type buttons as a move pool, not as a list of Pokémon on your team. If one teammate carries Fire and another carries Ground, selecting both Fire and Ground tells the Pokémon Type Coverage Calculator that your overall attack plan has access to those two offensive types. You can choose one type for a single-move check, two or three types for a compact offensive core, or a larger set when evaluating a full team.

Read the coverage buckets from top to bottom. Super effective types are the defensive types your current attack pool can punish. Normal means at least one chosen attack type hits for neutral damage, but none hits super effectively. Not very effective means the best available hit is resisted. No effect means every available attack option is blocked by immunity for that defensive type. The recommendation section looks only at currently uncovered or neutral areas and suggests extra attacking types that would add the most new super effective coverage.

The detail table is useful when the summary is too broad. It lists every defensive type, the best selected attack type into that defense, the best multiplier, and the final bucket. This makes the Pokémon Type Coverage Calculator practical for comparing two possible move additions, checking whether a team has enough Ground or Ice coverage, or seeing why a particular defensive type remains awkward.

Formula & Theory - Pokémon Type Coverage Calculator

The Pokémon Type Coverage Calculator uses the standard single-type effectiveness chart for mainline Pokémon-style type matchups. For each defensive type, it checks every selected attacking type and keeps the strongest multiplier:

best_multiplier(defense) = max(effectiveness(attack_type, defense_type))
for every attack_type in selected_attack_types

The best multiplier is then placed into a coverage bucket:

if best_multiplier >= 2:
    bucket = super effective
else if best_multiplier == 1:
    bucket = normal
else if best_multiplier > 0 and best_multiplier < 1:
    bucket = not very effective
else:
    bucket = no effect

Overall coverage rate is the share of the eighteen defensive types that can be hit for super effective damage:

coverage_rate = super_effective_defense_type_count / 18 * 100

Supplement recommendations compare each candidate attacking type against the defensive types that are not already super effective. A candidate ranks higher when it creates more new super effective matchups:

added_coverage(candidate) =
    count(defense_type where current_bucket != super effective
    and effectiveness(candidate, defense_type) >= 2)

This approach intentionally stays focused. The Pokémon Type Coverage Calculator does not include Pokémon GO CP, IVs, candy, evolution costs, species data, abilities, held items, weather, terrain, Same Type Attack Bonus, damage rolls, move power, accuracy, or speed control. It is a coverage planner, not a battle simulator. It also treats defenders as single defensive types. For dual-type defenders, the standard theory is to multiply both defensive modifiers, which can create 4x weaknesses, 0.25x resistances, or immunities. Single-type analysis is still valuable because it shows the raw coverage shape before more detailed matchup modeling.

Use Cases for Pokémon Type Coverage Calculator

The Pokémon Type Coverage Calculator is useful when you are building a team, choosing moves, or comparing offensive cores. It gives a quick view of whether your plan has broad super effective reach or whether it leans too heavily on neutral hits.

• Team attack coverage - Select the attacking types your planned team can use and see which defensive types are already pressured.
• Move slot decisions - Compare whether adding Ice, Ground, Fighting, Fairy, or Electric coverage solves more uncovered matchups.
• Core comparison - Test compact combinations such as Fire plus Ground, Water plus Ice, or Electric plus Fighting.
• Teaching type matchups - Use the bucket table to explain resistances, immunities, and why some attack types are valuable supplements.
• Avoiding overlap with candy planning - Keep type strategy separate from Pokémon GO evolution candy or resource calculators.

For best results, treat the output as a first-pass map of your attacking options. A high coverage rate is helpful, but it does not automatically mean a team is balanced. Defensive synergy, move availability, speed, bulk, format rules, and the real opponent pool still matter. The Pokémon Type Coverage Calculator gives you a clean starting point: identify the weak spots, try one supplement type, then compare the coverage rate and detail table before committing to a move or teammate.
