Comparing Marmot Size to Similar Animals

Comparing Marmot Size to Similar Animals

Let’s get to know how marmots are different with our wildlife size comparison.

Marmot vs Rodents

The most common rodents are the squirrels such as ground squirrels, flying squirrels, tree squirrels, and chipmunks. However, most are smaller than the marmot or ground squirrel. Let’s see the marmot size compared to other rodents.

Prairie Dogs

Prairie dogs are usually 30-40 cm in size and have thin small tails. They look so similar to the marmots as they’re considered the closest rodents to them.

You can distinguish them with their tails as they’re hard to differentiate with sizes.

Marmot vs Rodents

Flying Squirrel

In the case of flying squirrels, they are grayish, and their size is around 20 to 30 cm in length. So, they are so small compared to the marmots. 

Tree Squirrel

The size range of tree squirrels is wide. They can be 12-92 cm long and weigh 0.2 to 1.8 kg. They mainly live above the trees, and that’s how the name came.

Marmots live near grounds, so it’s easy to distinguish when you see a similar animal on trees; it’ll be a tree squirrel.


The chipmunks are even smaller and can be fitted on your palm. Their body length ranges from 8-16 cm, and their tail is 6-14 cm.  They’re so tiny that you won’t ever mistake if they’re marmot or not.


Capybaras are large rodents where adults weigh from 35 to 65 kg and their body size can be up to 140 cm. Although they are big, they look quite the same to the marmots, specifically the younger ones. 

However, they don’t have tails, unlike the marmots, so you can easily distinguish between them.

Marmot vs Other Mammals

Sometimes distinguishing marmots from other mammals can be hard if you’re not good with wildlife. Let’s see how they differ.

Marmot vs Other Mammals


Rabbits are smaller than most marmots. Any average house rabbit usually weighs around 3 kg, but the larger breeds can weigh 5 to 7 kg, while the mini breed weighs less than 2 kg. 

Also, their tails are so small compared to the marmots, only 5 cm long on average.


Foxes are quite large mammals compared to marmots, and they are also easily distinguishable. The usual foxes are red, light brown, or gray in color. 

Their average body size is 50 cm, and has very long and fluffy tail that ranges from 45 to 90 cm. 

The adult fox usually weighs between 5 to 7 kg. These foxes have quite large ears compared to the marmots, and their legs are also longer. 

If you’re interested in marmots, you might be wondering about the difference between marmot and groundhog or if they are endangered. At RodentsFact, we have articles on the difference between marmot and groundhog and are marmots endangered. Our article on difference between marmot and groundhog covers the similarities and differences between these two closely related rodents, while our article on are marmots endangered explores the status and conservation efforts for marmots in the wild. By learning about these aspects of marmots, you can gain a better understanding of their behavior and the threats they face in their natural habitat.


So, how big is a marmot compared to similar animals? Usually, depending on their species, region, food habits, age, and gender, their size fluctuates a lot. 

But despite these diverse characteristics, they can easily be distinguished between other rodents and mammals if you know the information properly.

We need to understand the wildlife size for emergencies, identifying and properly conserving them. Because if you find a rare breed of marmot with different food habits, and you treat them like other rodents or mammals, they can easily get sick and die. 

However, further research is needed to know more about the marmots with the help of wildlife conservation organizations because some of these species can be fatal for humans in one way or another.
