So, how much does a rabbit weigh? The answer varies based on breed, age, and overall health. A rabbit’s weight can indicate whether they are thriving, underfed, or at risk for obesity-related health problems.

In this guide, we’ll break down average rabbit weights by breed, explain how weight changes over a rabbit’s lifetime, and share tips for maintaining a healthy weight for your furry friend.

Why Does a Rabbit’s Weight Matter?

A rabbit’s weight is more than just a number, it’s a key indicator of their overall health. Underweight rabbits may suffer from malnutrition, while overweight rabbits can develop serious health issues such as arthritis and heart disease.

Monitoring weight regularly helps ensure your rabbit stays healthy and active. Veterinarians often recommend weighing rabbits at least once a month to track any significant changes.

How Much Does a Rabbit Weigh by Breed?

Rabbit breeds vary widely in size, from tiny dwarfs to large giants. Their weight depends largely on their breed and genetic background.

Small Rabbit Breeds

Small rabbit breeds are typically lightweight and ideal indoor pets. These breeds usually weigh between 1 to 5 pounds.

• Netherland Dwarf: 2 – 2.5 lbs

• Holland Lop: 4 lbs

• Polish Rabbit: 2.5 – 3.5 lbs

These rabbits are playful and make great additions to your household! However, because of their small size, they can be fragile. They require careful handling to avoid injury.

Medium Rabbit Breeds

Medium-sized rabbits are some of the most popular choices for pet owners. Their weight typically ranges from 5 to 10 pounds.

• Mini Rex: 3.5 – 4.5 lbs

• Havana Rabbit: 4.5 – 6.5 lbs

• Rex Rabbit: 7.5 – 10.5 lbs

Large and Giant Rabbit Breeds

Large rabbit breeds require more space, food, and exercise. Their weight typically ranges from 10 to over 20 pounds.

• Flemish Giant: 15 – 20 lbs

• Checkered Giant: 10 – 12 lbs

• French Lop: 10 – 15 lbs

Giant breeds, like the Flemish Giant, are known for their gentle nature but require large enclosures and plenty of food.

How Much Should a Rabbit Weigh at Different Ages?

A rabbit’s weight changes as they grow. Here’s a general guide to how much rabbits weigh at different life stages.

Newborn (0-2 Weeks)

Baby rabbits (kits) weigh between 1 to 2 ounces at birth. They are completely dependent on their mother for food and warmth.

Young Rabbits (3-8 Weeks)

By 8 weeks old, most kits weigh between 8 ounces and 2 pounds. They begin eating solid foods at around 3 weeks of age.

Adolescence (2-6 Months)

Rabbits experience rapid growth during this stage. Depending on the breed, by 6 months a medium-sized rabbit may weigh between 3 and 6 pounds.

Adult Rabbits (6 Months and Older)

By adulthood, rabbits reach their full weight. However, some larger breeds continue to grow until they are about a year old.

How to Weigh Your Rabbit at Home

Weighing your rabbit regularly helps monitor their health. Here’s how to do it at home:

• Use a digital kitchen scale for small rabbits.

• Use a baby scale for medium or large rabbits.

• Place your rabbit in a small box or carrier for easier weighing.

Record your rabbit’s weight monthly to track any changes. Sudden weight loss or gain may indicate a health issue and should be checked by a veterinarian.

What to Do If Your Rabbit is Overweight

Obesity in rabbits can lead to serious health problems, including arthritis, heart disease, and digestive issues. An overweight rabbit may also struggle to groom itself properly, leading to skin infections or dirty fur. If your rabbit is overweight, consider the following:

• Reduce pellet portions and offer more hay. Pellets should be a supplement, not the main food source. High-quality hay, such as timothy or orchard grass, should make up at least 80% of their diet.

• Increase exercise opportunities, such as free-roaming time. Encourage activity with tunnels, ramps, and toys to help them stay engaged and burn calories naturally.

• Provide more leafy greens and fewer high-calorie treats. Carrots and fruits should be given sparingly, as they are high in sugar. Opt for fresh herbs, and of course hay instead.

Weight loss should be gradual, so avoid drastic diet changes. For more information on a rabbit's diet click here. 

External Factors That Affect a Rabbit’s Weight

Besides diet and exercise, other factors influence a rabbit’s weight. Even with a balanced diet and proper care, some rabbits may naturally be smaller or larger due to factors beyond an owner's control. Here are a few key influences:

• Genetics: Some rabbits are naturally larger or smaller due to their breed. For example, a Mini Rex will never reach the size of a Flemish Giant, no matter how much they eat. Knowledge about your rabbit’s breed helps set realistic weight expectations.

• Metabolism: Just like humans, some rabbits have faster metabolisms and burn calories more quickly. Younger rabbits that are still growing generally have a higher metabolism than older ones, which means their food intake needs may change over time.

• Illness: Conditions like dental disease, parasites, or gastrointestinal issues can cause weight loss, even if a rabbit is eating normally. Regular vet checkups help catch these issues early before they lead to malnutrition.

If your rabbit’s weight changes unexpectedly, consult a veterinarian. For more on rabbit health, visit this resource on proper rabbit care.
