Maine Coon Size: What can I expect in the growth of my Maine Coon.

If you’re curious about the size of your Maine Coon cat and want to compare it to others, you’ve come to the right place. Let’s explore some key points about Maine Coon size and what you can expect from your cat.

Determining Maine Coon Size

The size of a Maine Coon is primarily determined by genetics, specifically the size of the parents. If your cat comes from a line of extra-large cats, it’s likely that they will also be hefty. There is no guaranteed way to predict how big a kitten will grow to be as an adult.

Male vs. Female Maine Coons

While it’s generally true that male Maine Coons are larger than females, there are exceptions. The size of a Maine Coon can depend on genetics and the breeding lines. A female Maine Coon can grow to be just as big as a male.

In general, male Maine Coons can weigh between 20 to 25 pounds (about 6.8 to 11kg), while females average around 10 to 15 pounds (about 4.5 to 6.8 kg).

Their large, rectangular-built body shape, big paws, and long hair can make them appear even bigger.

When is a Maine Coon Fully Grown?

Maine Coon cats are slow to mature and are not considered adults until they are between three to five years old. They are the largest domestic cat breed and take their time to reach their full size. So, if you have a Maine Coon kitten, it will take some time for them to grow into their big, beautiful adult size.

Length of a Maine Coon

The average size of an adult Maine Coon can range between 10 and 16 inches (about 25 and 41 cm) in height. They can reach a maximum length of 40 inches (about 100 cm), including their long tail, which can reach up to 14 inches (about 36 cm) in length.

Remember, these measurements are averages, and individual Maine Coons may vary in size. Appreciate your cat’s unique size and characteristics rather than focusing solely on comparisons. Enjoy watching your Maine Coon grow into their majestic size and embrace their larger-than-life presence.

The Record-holding Maine Coon

You’re absolutely right, the size of a Maine Coon cat can be quite impressive. It’s fascinating to learn about the record-holding Maine Coon, Barivel, who measured 47.2 inches long from nose to tail.

Maine Coons are one of the largest domestic cat breeds, known for:

  • Their tall and well-built stature,
  • Wide chest,
  • Long body,
  • Big slanted eyes,
  • Long and shiny coat, and
  • Bushy, long tail.

They are also known for their gentle and playful nature, making them great companions for families with kids and other pets.

Select a breeder based on the quality of their cats.

When choosing a Maine Coon breeder, it’s important to focus on the overall quality of the cats rather than solely on their size. While having a large cat may be visually impressive, it’s crucial to consider the potential health risks associated with extreme size. Extra-large cats can be more prone to hip dysplasia, heart disease, and arthritis. It’s essential to prioritize the well-being and long-term health of the cat over size alone.

Avoid getting too fixated on size.

I encourage you to do thorough research when selecting a Maine Coon breeder. Look for breeders who prioritize the health and temperament of their cats, provide proper veterinary care, and have a good reputation within the Maine Coon community.

Remember, Maine Coons are naturally large cats, and they will always appear bigger than a “regular” cat, even without extreme breeding for size. Focus on finding a reputable breeder who prioritizes the overall health and well-being of their cats.

Lies About Size

It can be easy to get caught up in the excitement and desire for a large, impressive Maine Coon. However, beware of breeders who advertise large sizes or use terms like “Mega” or “Giant” Coons. These breeders may prioritize size over health and may engage in unethical breeding practices to achieve extreme sizes.

Some Maine Coon buyers are obsessed with getting a huge maine coon, that can sometimes lead a breeder into lying and saying their cats weigh 30 pounds! Nobody is going to come weigh their cats so they can say whatever they want. and when the buyers come to us and we tell them the real weight of our cats which lies exactly where it should. 

some buyers think an 18 pound cat is not big enough. An 18 pound cat is plenty big!

Some breeds develop healtth issues becasue we keep pushing the standard to it’s extremes and of course that comes with health issues. We are honest in our estimation of our maine coon’s weights. 

Our males range from 18-20 and our females from 12 to 17, which means our cats are big cats as they should be, and some of their offspring exceed that size by much, but it’s an exception. not to be expected in each case.

Trick Photography – Creating the Illusion of Size

The Maine Coon has become an internet sensation, captivating cat enthusiasts worldwide with its stunning appearance, impressive size, and regal presence. The demand for these “big” cats has skyrocketed, leaving many intrigued by their magnificence.

For those unfamiliar with this photography technique, get ready to discover something fascinating.

You see when an object is positioned closer to the camera lens than the objects in the background, it can appear larger in the resulting photograph. Why not try it out for yourself? Take two cups of the same size and place them on a table about 12 inches apart, arranging them diagonally so both are visible.

The Size Of their intelligence

One of the most remarkable qualities of Maine Coons is their intelligence. These cats have been known to be highly trainable and have even been taught to perform tricks!

They also possess an independent streak, making them perfect for those who want a cat that’s not overly clingy but still enjoys companionship. This mix of intelligence and independence makes Maine Coons incredibly adaptable and able to thrive in various living situations.

Another unique aspect of Maine Coons is their love for water. Unlike most cats who avoid water at all costs, Maine Coons seem to enjoy playing in it or even joining their owners in the shower or bath. 

Size and Health problems in Maine Coons 

Maine Coons are large, with males typically weigh between 13-18 pounds and females weighing between 9-12 pounds. These cats have a sturdy and muscular build, making them excellent hunters. However, their size also puts them at risk for certain health problems, such as hip dysplasia and heart issues.

Hip dysplasia is a condition where the thigh bone does not fit properly into the hip joint, causing pain and discomfort for the cat. Proper nutrition is important, and exercise to reduce pressure on the joints.

Heart issues, specifically hypertrophic cardiomyopathy (HCM), are also common in Maine Coons. This is a genetic condition that causes thickening of the heart muscle, potentially leading to heart failure. Regular check-ups with a veterinarian and proper monitoring can help catch this condition early on.

With proper care and attention to their unique needs, they can live up to 12-15 years or even longer.

The Size Of Their Heart

In addition to their physical characteristics, Maine Coons are also friendly and affectionate. They are often described as “gentle giants” because they are calm and loving . They get along well with other pets and children, making them great additions to any family.


In conclusion, while each Maine Coon may vary in size, there are some general expectations to keep in mind. On average, male Maine Coons can weigh 15-25 pounds and grow 40 inches, while females typically weigh 10-15 pounds and measure around 36 inches.

Expect your Maine Coon to be a large and majestic cat with plenty of love and personality to offer. Love their size and characteristics, and enjoy the journey of watching them grow into the magnificent breed they are.
