Dolphins are truly creatures that capture our attention with their movements and remarkable intelligence. There is a common question when to discuss dolphin is “how much does a full grown dolphin weigh”.
In this article we will discuss factors influencing weight of a dolphin in aspects like size, dimensions and dietary habits. By comprehending these underlying factors, we can develop an admiration for these marine mammals.
The short answer of “how much does a full grown dolphin weigh” is between 300 to 1,200 kilograms

How Much Does a Full Grown Dolphin Weigh?
The weight of an adult dolphin can vary significantly depending on factors such as individual species and their characteristics. Dolphins exhibit dimorphism wherein males tend to be larger and heavier compared to females.
On average adult dolphins weigh between 300 to 1,200 kilograms (660 to 2,650 pounds). However certain larger species like the killer whale or orca can reach weights up to 5,400 kilograms (11,900 pounds).
How Long Are Dolphins?
There are many varieties of sizes that depends from where the dolphin belongs to. It ranges from 4 feet to over 30 feet in length. Depending on the species the average length of a dolphin can range, between 6 to 12 feet.
Maui dolphin, the smaller species, has size around 4 to 5.5 feet. On the hand the orca, the largest one, can grow up to a size of 31 feet.

How Much Does A Bottlenose Dolphin Weigh?
The bottlenose dolphin (Tursiops truncatus) is one of the well-known and extensively studied dolphin species. They live both warm and temperate waters across the globe.
When fully matured a bottlenose dolphin can weigh between 300 to 500 kilograms (660 to 1,100 pounds) with males being slightly larger than females. The weight is depending of some parameters such as diet, age and location they lived.
How Tall Is a Dolphin?
Unlike land animals that are measured in terms of tallness dolphins don’t have that measurement as they are specially adapted for life in water. Instead of tallness they are measured in length.
The average length of a dolphin is around 6.6 to 12.8 feet (2 to 3.9 meters) from their snout, to the tip of their tail. It provides an accurate representation of their overall size and proportion.
How Much Do Dolphins Eat?
Dolphins are renowned for having appetites. On a day they consume 4 to 9% of their body weight in food.
This implies that a dolphin weighing 300 kilograms would typically consume around 12 to 27 kilograms (26 to 60 pounds) of food per day. Generally, their food consists of squid, fish and crustaceans. Moreover, their diet pattern can deviate according to their species and habitat.

Weight of Dolphin in Kg
Dolphin weight is commonly measured using the unit of kilograms (kg). This measurement method allows for analysis when comparing the weights of dolphins across different species and populations as opposed to using pounds or other units.
Scientists and researchers rely on kilograms to precisely track and compare dolphin weights. Here are some of the most common dolphin species and their average weight in kilograms:
| Dolphin Species | Average Weight (kg) |
| Bottlenose dolphin | 300-1,400 |
| Orca (killer whale) | 2,000-7,500 |
| Spinner dolphin | 100-230 |
| Risso’s dolphin | 250-400 |
| Atlantic spotted dolphin | 150-300 |
| Maui’s dolphin | 40-60 |
| Fraser’s dolphin | 150-250 |
| Long-beaked common dolphin | 150-250 |
| Melon-headed whale | 135-300 |
| Chinese river dolphin | 90-120 |
Dolphin Height and Weight
In the case of dolphin’s height is not a measure; instead their length is used. The length of a dolphin closely correlates with its weight and overall size.
However, their average length is 6.6 to 12.8 feet (2 to 3.9 meters). While factors such as age, sex and species influence height and weight variations among dolphins these marine creatures remain swimmers with bodies that enable exceptional agility and speed in water.
Dolphin Length in Feet
Depending on the species dolphins can range from 6.6 to 12.8 feet (2 to 3.9 meters) long.
Here is a table that demonstrates the average length of some common dolphin species in feet:
| Dolphin Species | Average Length (feet) |
| Bottlenose dolphin | 6.6-12.8 |
| Orca (killer whale) | 20-26 |
| Spinner dolphin | 5.5-8 |
| Risso’s dolphin | 6.6-9.8 |
| Atlantic spotted dolphin | 5-8 |
| Maui’s dolphin | 4-6 |
| Fraser’s dolphin | 6-10 |
| Long-beaked common dolphin | 6-10 |
| Melon-headed whale | 6-10 |
| Chinese river dolphin | 5-6 |
Frequently Asked Questions (FAQs)

No, dolphins reach their size and weight once they reach maturity.
Why are males generally larger and heavier than females?
This is due to dimorphism where males have evolved to be larger in order to compete for mates.
Are there any dolphins that weigh more than 5,400 kilograms?
Yes, the killer whale or orca is a type of dolphin that can grow, up to 5,400 kilograms in weight.
How do scientists measure the weight of a dolphin?
Scientists typically employ scales or buoyancy tanks to accurately measure the weight of dolphins.
How long do dolphins typically live?
Dolphins have a lifespan ranging from 20 to 50 years which can vary depending on factors such, as species and environmental conditions.
Conclusion
In conclusion the weight of dolphins can vary based on several factors such, as species, gender and individual characteristics. On an average adult dolphins weigh between 300 to 1,200 kilograms (660 to 2,650 pounds) with some species reaching weights up to 5,400 kilograms (11,900 pounds).
Dolphins come in sizes with lengths ranging from 6 to 12 feet depending on their species. Moreover, these incredible creatures have an appetite too much.
Consume a significant amount of food daily. By gaining knowledge about dolphin’s weight, length and food habit we are obliged to appreciate them to put a balanced ecosystem in marine environment.
