Penguins are flightless aquatic birds that live in the Southern Hemisphere.
They usually eat krill, fish, squid and other marine life.
Currently, penguins range in length from 35 cm to 115 cm and weigh from 1 kg to 40 kg.
The largest living penguin in the world is the emperor penguin with a length of 110 to 120 cm and a weight of 22.7 to 45.4 kg.
However, extinct penguins from other genera such as Archaeospheniscus (33 to 45 million years ago) were much taller and heavier.
This list includes the world’s 15 largest penguin species by height and weight (both living and extinct).

Its height is midway between a modern king penguin and an emperor penguin.
Height: 85-115 cm
Weight: Unknown
Status: Extinct
14. Archaeospheniscus lopdelli
Archaeospheniscus lopdelli is the largest species of Archaeospheniscus, an extinct genus of large penguins.
They were slightly smaller than modern emperor penguins.
Height: 85–120 cm
Weight: Unknown
Status: Extinct
13. Emperor Penguins
Emperor penguins are the tallest and heaviest penguins living in Antarctica.
Due to climate change, emperor penguins were listed from “Least Concern” to “Near Endangered” by the IUCN in 2012.
Height: 100-122 cm
Weight: 22-45kg
Status: Near Threatened
12. Palaeeudyptes gunnari
Palaeeudyptes gunnari is a species of Palaeeudyptes, an extinct genus of penguins.
They were about the same size as modern emperor penguins.
Height: 110-125 cm
Weight: Unknown
Status: Extinct
11. Kairuku grebneffi
Kairuku grebneffi is a species of giant penguin, an extinct species, that lived about 25 million years ago.
Kairuku’s bones were first discovered in 1977, but it was not until 2012 that it was classified as a species.
Height: 130cm
Weight: 60kg (50% heavier than emperor penguins)
Status: Extinct
10. Palaeeudyptes antarcticus
Palaeeudyptes antarcticus, or narrow flipper penguin, is a species of the genus Palaeeudyptes, an extinct genus of penguins.
It was the first known penguin fossil, discovered in late 1848 by Agent Walter Mantell.
Height: 110-140 cm
Weight: Unknown
Status: Extinct
9. Palaeeudyptes marplesi
Palaeeudyptes marplesi is a species of the genus Palaeeudyptes, an extinct genus of penguins.
It is slightly larger than the narrow flipper penguin (Palaeeudyptes antarcticus).
Height: 105-145 cm
Weight: Unknown
Status: Extinct
8. Anthropodyptes gilli
Anthropodyptes gilli is a little known extinct species of penguin.
It is the only species of Anthropodyptes, a monotypic genus of the extinct penguin.
Height: 140-150 cm
Weight: Unknown
Status: Extinct
7. Inkayacu paracasensis
Inkayacu paracasensis is a species of Inkayacu, an extinct genus of penguins.
It lived about 36 million years ago in Peru during the Late Eocene.
One study found them to be gray or reddish brown, different from modern black and white penguins.
Height: 150cm
Weight: 55-60kg
Status: Extinct
6. Icadyptes salasi
Icadyptes salasi is a species in the genus Icadyptes, an extinct genus of giant penguins.
They lived about 35 to 37 million years ago, during the second half of the Eocene.
Icadyptes thrived in warmer climates during the Eocene.
Height: 150cm
Weight: 50-80kg
Status: Extinct
5. Crossvallia waiparensis
Crossvallia waiparensis is one of two species of Crossvallia, an extinct genus of penguins.
Their remains were discovered by paleontologist Leigh Love in August 2019.
Height: 140-160 cm
Weight: 70-80kg
Status: Extinct
4. Pachydyptes weight
Pachydyptes is the only species of Pachydyptes, an extinct genus of penguins.
It is slightly larger than Icadyptes salasi.
Height: 150-160 cm
Weight: 80-100kg
Status: Extinct
3. Palaeeudyptes klekowskii
Palaeeudyptes klekowskii, or giant penguin, is a species of the genus Palaeeudyptes, an extinct genus of penguins.
A recent study found them to be almost twice as tall as Palaeeudyptes antarcticus.
Height: 150-160 cm
Weight: 115 kg
Status: Extinct
2. Kumimanu Biceae
Kumimanu biceae is an extinct species of giant penguin, known to be the second largest penguin that ever lived in the world.
Its fossils were found in New Zealand, but the discovery was only announced in December 2017.
Height: 160-177 cm
Weight: 91-100kg
Status: Extinct
1. Anthropornis nordenskjoeldi
The world’s largest penguin is Anthropornis nordenskjoeldi, which lived more than 33 million years ago during the Late Eocene.
It is about 1.80 m (5’11 in) tall and weighs 90 kg (200 lb), about the same as an adult male.
Meanwhile, the largest modern penguin, the emperor penguin, is only 1.2 meters tall.
Fossils of Anthropornis nordenskjoeldi have been found in New Zealand and the La Meseta Formation on Seymour Island off the coast of Antarctica.
The penguin has a curved joint in its wings most likely inherited from its flying ancestors.
Height: 170-180cm
Weight: 82-90kg
Status: Extinct
Conclusion
Penguins are commonly known as small flightless birds.
However, penguins were very large in prehistoric times (millions of years ago).
This is due to the higher oxygen content in the air and the larger land area in the past.
Palaeeudyptes and Anthropornis are two of the largest genera of large penguins.
They are up to 1.8 meters tall and weigh as much as an adult.
For comparison, emperor penguins are only 1.2 meters long.
