Weight (Japanese: おもさ weight) is a measure of the mass of a Pokémon. This is measured in kilograms (in all languages except English) or pounds (in English).


List of Pokémon by weight

Main article: List of Pokémon by weight

Every Pokémon species has a specific weight that is displayed in the Pokédex for that species. Some species have different weights in different forms.

In the core series games

Reason: Does Transform copy weight, and if so, does the Heavy Ball consider the original species' weight or the new weight?
Does Transform copy Autotomize's weight loss, and does transforming cause the user to lose its own Autotomize weight loss?

You can discuss this on the talk page.

The Pokédex lists a weight for each Pokémon species. In English, weight is displayed in pounds (to one decimal place); in all other languages, it is displayed in kilograms (to one decimal place). All game mechanics based on weight use kilograms for their calculations.

In most core series games, all members of the species in the same form have the same weight.

In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! (like in Pokémon GO), each individual Pokémon has its own weight, with the value in the Pokédex simply being an average weight for Pokémon of that species.

Weight-modifying effects

From Generation V onward, there are several effects that can modify a Pokémon's weight in battle.

  • A Pokémon with the Ability Heavy Metal or Light Metal functions as twice or half its normal weight, respectively.
  • A Pokémon holding a Float Stone functions as if it weighed half the weight listed in the Pokédex.
  • A Pokémon that uses Autotomize has its base weight decreased by 100 kg (220 lbs.) each time it uses the move. This weight loss applies before other weight-modifying effects.

A Pokémon's weight cannot drop below 0.1 kg.

From Generation VI onward, if a Pokémon changes form, any weight modifications due to Autotomize are lost.

Weight affects the following game mechanics. Because the games use weight in kilograms for functional purposes, metric values are shown first, followed by United States customary values.

Low Kick and Grass Knot

The moves Low Kick (from Generation III onward) and Grass Knot have a base power of 20, increasing in power at based on the target's weight, at specific increments.

Target's weight Power
Metric US customary
0.1 - 9.9 kg 0.1 - 21.8 lbs.
10.0 - 24.9 kg 21.9 - 55.0 lbs.
25.0 - 49.9 kg 55.1 - 110.0 lbs.
50.0 - 99.9 kg 110.2 - 220.2 lbs.
100.0 - 199.9 kg 220.4 - 440.7 lbs.
200.0 kg or more 440.9 lbs. or more

Heat Crash and Heavy Slam

151Mew.png This move effect may be in need of research.
Reason: Power when target weights exactly 25% or 20% of the user's weight
You can discuss this on the talk page.

The power of the moves Heat Crash and Heavy Slam depends on the weight of both the user and the target; the lighter the target is in comparison to the user, the greater the power.

Target's relative weight Power
More than 50% 40
33.34% - 50% 60
25% - 33.33% 80
20% - 25% 100
20% or less 120

Sky Drop

From Generation VI onward, Pokémon weighing at least 200 kg (440.9 lbs.) cannot be taken into the air by another Pokémon's Sky Drop.

Heavy Ball

In games in which Heavy Balls are available, using them modifies the catch rate of the targeted Pokémon depending on its weight (ignoring weight-changing effects).

Battle rules

Pokémon weighing more than 20.0 kg (44.1 lbs.) are not eligible to compete in the Fancy Cup (known as the Petit Cup in Generation I).

Pokémon weighing more than 99.0 kg (218.3 lbs.) are not eligible to compete in the Light Cup.

Battle entry animation

Since Generation V, certain visual and sound effects are applied when a Pokémon lands on the surface of a battlefield, depending on the Pokémon's weight (ignoring weight-changing effects). Diglett, Dugtrio, and Pokémon that float above the surface of the battlefield do not cause any such effects. Pokémon holding an Air Balloon also do not cause any such effects, even if the item's function is being suppressed by Klutz or Magic Room.

  • Small shake and high-pitched landing noise for Pokémon weighing 49.9 kg (110.0 lbs.) or less.
  • Medium shake and lower landing noise for Pokémon weighing between 50 kg (110.2 lbs.) and 149.9 kg (330.5 lbs.).
  • Heavy shake, crashing sound and dust for Pokémon weighing 150 kg (330.7 lbs.) or more.


In Pokémon X and Y, in the "Compare" section of the Pokédex, if the player taps a Pokémon's menu sprite, ten simplified Flying-type Pokémon sprites will fly onto the screen, encircle and lift the Pokémon's model up, before dropping, with a number of them flying off the screen, with the number remaining depending on the Pokémon's weight; more Flying-type Pokémon will remain for heavier Pokémon. If the Pokémon is Diglett, Dugtrio, or Mega Gengar, the Flying-type Pokémon will all disperse before even attempting to lift it.

2 At most 9.9 kg (21.8 lbs.)
3 Between 10.0 kg (22.0 lbs.) and 29.9 kg (65.9 lbs.)
4 Between 30.0 kg (66.1 lbs.) and 59.9 kg (132.1 lbs.)
5 Between 60.0 kg (132.3 lbs.) and 99.9 kg (220.2 lbs.)
6 Between 100.0 kg (220.5 lbs.) and 149.9 kg (330.5 lbs.)
7 Between 150.0 kg (330.7 lbs.) and 209.9 kg (462.8 lbs.)
8 Between 210.0 kg (463.0 lbs.) and 279.9 kg (617.1 lbs.)
9 Between 280.0 kg (617.3 lbs.) and 359.9 kg (793.4 lbs.)
