Understanding Deer’s Weight

Factors Influencing Weight

When considering a deer’s weight, several factors play a role in determining their overall size. Some of these factors include their age, sex, diet, and the deer species. It’s essential to note that these weights can vary significantly, even within the same species.

For example, a whitetail deer’s weight will differ from that of a mule deer or an elk. (More about deer species will be discussed in the succeeding sections).

Male deer, also known as bucks, are generally heavier than females (does), while younger deer will weigh less than mature ones.

Additionally, the quality and availability of food can significantly impact a deer’s weight.

Common Misconceptions

Deer weights are a topic often misunderstood, and misconceptions may arise. One common misconception is that some deer weigh much heavier than they truly are, reaching up to 1000 pounds or more. While there may be individual cases of larger deer, this weight is far from the average and is not the norm for deer populations.

Another misconception is that a deer’s weight can be accurately estimated by merely observing or photographing them at a distance. In reality, it is tough to determine a deer’s weight without physically weighing them, as their body shape and size can be misleading.

So, to better understand deer’s weight, consider the different factors influencing it, be aware of common misconceptions, and remember that variation in size and weight is common in the natural world.

Common Deer Species and Their Weight Ranges

Deer come in various sizes, so the weight of a deer varies greatly depending on the species. Let’s take a look at some common species and their average weights.

White-tailed Deer

White-tailed deer are found across most of North America. The size of these deer can vary depending on their habitat.

When it comes to weight, you’ll find that there’s a noticeable difference between males and females as well as between adults and fawns. Let’s examine the average weight of this species according to their gender and age.

Adult Males: Adult male white-tailed deer, also known as bucks, typically weigh between 150 and 250 pounds. However, their weight can depend on factors such as their habitat, diet, and season. In some cases, large and well-fed bucks can weigh up to 300 pounds or more.

Adult Females: Adult female deer, called does, are generally smaller than males. Their average weight ranges from 90 to 200 pounds. Like bucks, factors like habitat, diet, and season can affect their weight. It’s worth noting that pregnant does usually weigh more during the late stages of pregnancy.

Fawns: Newborn fawns are much lighter than full-grown deer, usually weighing between 4 and 8 pounds at birth. As they grow, their weight increases quickly.

By the time fawns reach six months, they typically weigh anywhere from 50 to 100 pounds, depending on their gender and other factors mentioned earlier.

Mule Deer

Mule deer are typically found in the western part of North America. Typically, These species are characterized by their large, mule-like ears and their black-tipped tails.

When discussing the weight of a mule deer, it’s important to consider that their weight can vary based on factors such as age, geographical location, and diet.

Generally speaking, adult male mule deer (bucks) can weigh between 130 to 280 pounds (59 to 127 kg), while adult female mule deer (does) tend to be lighter, weighing between 95 to 200 pounds (43 to 91 kg).

When it comes to mule deer fawns, there is a significant difference in size. Newborn fawns typically weigh around 4.5 to 8 pounds (2 to 3.6 kg) at birth. As they grow older, their weight increases rapidly: by the end of their first year, they can easily be about half the size of an adult doe.

To better grasp these weight differences, consider the following:

  • Bucks: 130 to 280 pounds (59 to 127 kg)
  • Does: 95 to 200 pounds (43 to 91 kg)
  • Fawns: 4.5 to 8 pounds (2 to 3.6 kg) at birth, increasing rapidly in their first year


Elk inhabit much of the western United States, as well as parts of Canada. While not as common as white-tailed or mule deer, they are much larger.

Elk Male (Bull): 700-1,100 pounds, Female (Cow): 500-800 pounds

Roe Deer

Roe deer are relatively small and lightweight compared to other deer species. Generally, their weight ranges between 33 and 77 pounds (15-35 kg).

Male roe deer, also known as bucks, are typically heavier than the females, called does. Adult bucks usually weigh between 44 and 77 pounds (20-35 kg), while adults does weigh around 33 to 55 pounds (15-25 kg).

Remember that these are average weights, and individual deer may weigh slightly more or less.

Roe deer newborns typically weigh just 4.4 to 6.6 pounds (2-3 kg). Fawns will rapidly grow during their first year, reaching about half of their adult weight by the time they’re six months old.

Factors like geographical location, nutrition, and habitat quality can also influence the weight of a roe deer. For example, a deer living in a nutrient-rich area with abundant food sources will likely have a better chance of reaching its full potential than one living in an area with more limited resources.

Now, you have learned the popular deer species and their weight ranges by age and gender. Just to reiterate, these weights are mere averages and actual weights may deviate from these guidelines due to other influencing factors such as habitat and available resources.
