# Heaviest and Lightest Pokémon: Weight, Height and the Strange Cases

Cosmoem and Celesteela are the heaviest Pokémon. Both weigh 999.9 kg (2,204.4 lb). The lightest weigh just 0.1 kg (0.2 lb): [Gastly](https://pokee.si/pokemon/gastly), [Haunter](https://pokee.si/pokemon/haunter), [Flabébé](https://pokee.si/pokemon/flabebe), [Cosmog](https://pokee.si/pokemon/cosmog) and [Kartana](https://pokee.si/pokemon/kartana) all tie.

The tallest is [Eternatus](https://pokee.si/pokemon/eternatus), at 20 m. The smallest are only 0.1 m tall, and one of them, Cosmoem, is also the heaviest.

## The heaviest Pokémon

Twelve Pokémon weigh 699 kg or more. The top two are tied, so [Cosmoem](https://pokee.si/pokemon/cosmoem) and [Celesteela](https://pokee.si/pokemon/celesteela) share first place.

| # | Pokémon | Type | Weight | Height |

| 2 | [Celesteela](https://pokee.si/pokemon/celesteela) | [Steel/Flying](https://pokee.si/types/flying-steel) | 999.9 kg (2,204.4 lb) | 9.2 m |
| 3 | [Groudon](https://pokee.si/pokemon/groudon) | [Ground](https://pokee.si/types/ground) | 950 kg (2,094.4 lb) | 3.5 m |
| 4 | [Eternatus](https://pokee.si/pokemon/eternatus) | [Poison/Dragon](https://pokee.si/types/poison-dragon) | 950 kg (2,094.4 lb) | 20 m |
| 5 | [Mudsdale](https://pokee.si/pokemon/mudsdale) | [Ground](https://pokee.si/types/ground) | 920 kg (2,028.3 lb) | 2.5 m |
| 6 | [Guzzlord](https://pokee.si/pokemon/guzzlord) | [Dark/Dragon](https://pokee.si/types/dragon-dark) | 888 kg (1,957.7 lb) | 5.5 m |
| 7 | [Stakataka](https://pokee.si/pokemon/stakataka) | [Rock/Steel](https://pokee.si/types/rock-steel) | 820 kg (1,807.8 lb) | 5.5 m |
| 8 | [Melmetal](https://pokee.si/pokemon/melmetal) | [Steel](https://pokee.si/types/steel) | 800 kg (1,763.7 lb) | 2.5 m |
| 9 | [Glastrier](https://pokee.si/pokemon/glastrier) | [Ice](https://pokee.si/types/ice) | 800 kg (1,763.7 lb) | 2.2 m |
| 10 | [Giratina](https://pokee.si/pokemon/giratina) | [Ghost/Dragon](https://pokee.si/types/ghost-dragon) | 750 kg (1,653.5 lb) | 4.5 m |
| 11 | [Cetitan](https://pokee.si/pokemon/cetitan) | [Ice](https://pokee.si/types/ice) | 700 kg (1,543.2 lb) | 4.5 m |

Look at the Height column for Cosmoem. It is only 0.1 m tall, which makes it one of the smallest Pokémon, yet it is also the heaviest. And Cosmog, the Pokémon it evolves from, weighs only 0.1 kg. That is a jump from 0.1 kg to 999.9 kg in one evolution.

The Guinness World Records entry for the heaviest Pokémon lists the same weight. Celesteela is an Ultra Beast, and you can read about the whole group in the [Ultra Beasts list](https://pokee.si/articles/ultra-beasts-list).

Across all Pokémon, the average weight is 67.0 kg and the median is 28 kg. Only 18 Pokémon weigh over 500 kg. [Snorlax](https://pokee.si/pokemon/snorlax) weighs 460 kg. Wailord is 14.5 m tall in the Pokédex but weighs 398 kg.

### Heavier forms

Some forms are heavier than their normal Pokémon. These are the heaviest forms in the data, from the heaviest down:

- [Primal Groudon](https://pokee.si/pokemon/groudon?form=groudon-primal) 999.7 kg, [Mega Metagross](https://pokee.si/pokemon/metagross?form=metagross-mega) 942.9 kg, [Origin Dialga](https://pokee.si/pokemon/dialga?form=dialga-origin) 848.7 kg, [Ice Calyrex](https://pokee.si/pokemon/calyrex?form=calyrex-ice) 809.1 kg, [Crowned Zamazenta](https://pokee.si/pokemon/zamazenta?form=zamazenta-crowned) 785 kg, [Mega Steelix](https://pokee.si/pokemon/steelix?form=steelix-mega) 740 kg

Gigantamax forms are left out of the weight lists. The games give their heights as "more than" a number, and they do not give Gigantamax weights at all. You can read more in the [Gigantamax list](https://pokee.si/articles/gigantamax-pokemon-list).

## Can a Pokémon be even heavier?

Yes. The Ability [Heavy Metal](https://pokee.si/abilities/heavy-metal) doubles a Pokémon's weight. If Cosmoem or Celesteela gets it, with [Skill Swap](https://pokee.si/moves/skill-swap) or Entrainment, its weight becomes 1,999.8 kg. That is the heaviest any Pokémon can be in the games.

## The lightest Pokémon

Five Pokémon tie at 0.1 kg, so the order of the first five rows is not a ranking.

| Pokémon | Type | Weight | Height |
| --- | --- | --- | --- |
| [Kartana](https://pokee.si/pokemon/kartana) | [Grass/Steel](https://pokee.si/types/grass-steel) | 0.1 kg (0.2 lb) | 0.3 m |

| [Rotom](https://pokee.si/pokemon/rotom) | [Electric/Ghost](https://pokee.si/types/electric-ghost) | 0.3 kg (0.7 lb) | 0.3 m |

Guinness World Records and Bulbapedia also list Gimmighoul's Roaming Form at 0.1 kg. The gap between the lightest and the heaviest is huge: 999.9 kg is 9,999 times 0.1 kg. In the data, 46 Pokémon weigh 1 kg or less.

[Eternatus](https://pokee.si/pokemon/eternatus) is the tallest at 20 m. Eternamax Eternatus is 100 m tall, but players cannot use that form. For the top 25, the tallest of every type and the Gigantamax heights, see [tallest Pokémon](https://pokee.si/articles/tallest-pokemon).

## Moves that care about weight

Four moves use weight to decide how hard they hit. [Heavy Slam](https://pokee.si/moves/heavy-slam) and [Heat Crash](https://pokee.si/moves/heat-crash) hit harder when the user is heavier than the target. [Low Kick](https://pokee.si/moves/low-kick) and [Grass Knot](https://pokee.si/moves/grass-knot) hit harder when the target is heavier.

## Look for more

Use the [Higher or Lower](https://pokee.si/games/higher-lower) game to guess which Pokémon is heavier, or use [Compare](https://pokee.si/compare) to put two Pokémon side by side. If you like speed more than size, see the [fastest Pokémon](https://pokee.si/articles/fastest-pokemon).
