How Big is a Whale? List of Whales by Size

There is a lot of curiosity when it comes to some of Earth’s largest creature- the whale. A question is often asked, “What is bigger than a whale?” Well, that answer depends solely on which whale species you are referring to! Each species ranges in shapes and sizes, each impressive in their own way. Below we will discuss ten whale species, both Baleen and toothed, starting from largest to smallest.

Blue Whale

The Blue Whale is not only the largest whale species, but the largest mammal on Earth. Therefore, to answer the earlier question, no creature on this planet is larger than the Blue Whale! Weighing at about 173 tons, the Blue Whale can grow to be about 98 feet (30 meters). That is equivalent to the length of three school buses lined up! Due to their enormous size, if you are left wondering what is the largest thing a whale can swallow, the answer is- a grapefruit! Their throat is about the size of plate, which is why they feed on plankton and small fish.  

Fin Whale

The Fin Whale is next in line as the second largest whale species in the world. These grow to be about 90 feet long (27.5 meters). Although they are close in length to the Blue Whale, this species only weighs about 72 tons due to their slim shape.  

Sperm Whale

The Sperm Whale is the largest toothed whale in existence, getting to be an average of 67 feet in length (20.5 meters). Males can weigh up to 56 tons. It has been said that this whale species may have decreased in overall size due to the large amount of whaling in the past. Fun fact: Sperm Whales have the largest brain of any known mammal on Earth while their heads take up one third of their body length!

Right Whale

The Right Whale is extremely robust. But how big is a full grown whale? On average, it grows to be about 59 feet long (18 meters). However, the largest known Right Whales grew to be 65 feet (19.8 meters). Being solidly built, Right Whales are significantly heavier than other whales, weighing around 100 tons. This makes them second in line to the Blue Whale based off of sheer body mass.

Bowhead Whale

The Bowhead Whale is one of the more thick-bodied whales.Their length ranges from about 46-59 feet (14-18 meters). Their weight averages at around 75 tons but can reach to around 100 tons.

Humpback Whale

The Humpback Whale, one of the most popular for whale watchers due to their breaching habits, reach about 52 feet (16 meters) and can weigh about 30 tons!

Sei Whale

By maturity, the Sei Whale can get to be 52 feet in length and weigh as much as 28 tons.

Gray Whale

The Gray Whale is another crowd favorite. Once called devil fish due to their ferocious fighting behavior against hunters, these valiant creatures can reach about 49 feet in length (14.9 meters) and weigh around 40 tons.

Bryde’s Whale

The Bryde’s Whale ranges in size depending on where they are located. Their size averages at about 46 feet. However, the largest females found have been about 50 feet in length while the male is around 47 feet. Their weight ranges from 13-28 tons.

Minke Whale

The Minke Whale is the second smallest Baleen whale (Pygmy Right Whale is the first). On average, females are 26 feet in length while males are around 23 feet. Both average at about 6 tons in weight. At their largest, females can be around 35 feet and males at 32 feet, both around 11 tons in weight.
