Maine Coon Size Compared To Humans
Maine Coons are the largest domesticated cat breed in the entire world. So, it is no surprise that the Maine Coon size compared to human beings is very different from that of a normal cat!
These gentle giants can grow so large, that they might even surpass the size of your child!
The average Maine Coon weighs between 8 and 25 pounds when fully grown. Since the average human weighs between 19 and 21 pounds at a year old, a Maine Coon cat can easily surpass the size of an infant. However, because Maine Coons do not reach their full size until between 3 and 5 years old, a baby Maine Coon will be much smaller than a baby human.
Cat lovers all over the world are in love with the Maine Coon’s enormous size.
However, their slow growth rate means that most Maine Coons will not reach full weight until they are much older.
Read on to find out how a Maine Coon’s growth rate compares to that of a human, as well as how much bigger Maine Coons are than normal cats (source 1).
Maine Coon Size Compared To Human
The Maine Coon is a unique cat breed prized for its enormous size.
These cats developed naturally in the northern United States, specifically the state of Maine, where these cats developed long, thick fur to protect themselves from the elements.
Today, they are becoming increasingly popular not only for their size but also for their friendly, gentle personalities.
Humans, meanwhile, are much larger than Maine Coons.
While we humans may be much smaller in comparison to giant cat breeds such as lions and tigers, even the largest of Maine Coons is no match for a fully grown human.
Still, as the Maine Coon grows in popularity, it is becoming increasingly evident that we humans enjoy having large cats by our sides!
A Maine Coon size comparison to human beings shows that humans are significantly larger.
However, an adult Maine Coon vs a human baby is a different story; since a fully grown Maine Coon is often much larger than an infant.
As a baby, though, the Maine Coon kitten’s average weight is only a fraction of a pound, usually just between .19 and .37 pounds at birth.
The table below was created by Maine Coon Central and shows you just how big a Maine Coon is at each stage of its life in comparison to a human:

Of course, while this table is helpful as a rough guide, it only includes average estimates and does not include the extremes.

While the average Maine Coon weighs between 8 and 25 pounds as an adult, the largest Maine Coon weight was an incredible 34 pounds!
The title for biggest Maine Coon in the world goes to Stewie, a gentle Maine Coon who measured a total of 48.5 inches long! When you compare that to the biggest human in the world, though, Stewie seems quite tiny in comparison.
The tallest human ever recorded was Robert Wadlow, who measured 8 feet and 11.09 inches!
While Stewie and Wadlow never got to meet in real life, the two probably would have gotten along quite well, as they were both remembered for their gentle personalities (sources 1,2,3).

Maine Coon Size Chart
As adults, Maine Coons are incredibly enormous. Some normal cats are only about half Maine Coon cat size!
However, Maine Coon size by age looks very different from the average cat, as Maine Coons take much longer to reach their full size.
If you are wondering about the growth stages of a Maine Coon cat, here is a handy guide to Maine Coon size based on age:
- Newborn: .19 to .37 pounds, or about 3 to 6 ounces
- 1 Month: 1.2 to 1.8 pounds
- 2 Months: 2.2 to 3.5 pounds
- 3 Months: When they reach three months old, you can expect a Maine Coon to weigh between 3.3 and 5.3 pounds. At this point, the kitten will begin gaining about two pounds every month until they are roughly 7 months old.
- 4 Months: 5.5 – 8.4 lb
- 5 Months: 6 – 12 lb
- 6 Months: 6.8 – 13.2 lb
- 7 Months: 7.3 – 14.3 lb
- 8 Months: At around 8 months old, Maine Coons experience a major growth spurt. Kittens this age typically weigh between 8.1 and 15.2 lb.
- 9 Months: 9 – 15.3 lb
- 10 Months: 8.8 – 17.2 lb
- 11 Months: 9.5 – 17.6 lb
- 1 Year: Maine Coons typically have their final growth spurt when they are about a year old, or around 50 weeks old.
- Over 1 Year: Grow at a slow, steady rate until they reach their full size when they are between 3 and 5 years old.
- 3 – 5 years: Most Maine Coons weigh between 9.9 to 19.9 pounds.
Most of the Maine Coon’s growth takes place during their first year of life, but they will not stop growing until they are about three to five years old.
So, how big is a fully-grown Maine Coon?
Once they reach full weight, these cats can weigh between 8 and 25 pounds. In addition, they typically measure between 8 and 16 inches tall, and about 40 inches long.
If you plan on getting a Maine Coon as a kitten, it is a good idea to keep track of its size over time.
This is a helpful way to track your kitten’s growth spurts, of which there will typically be three in their lifetime.
Tracking their weight is also beneficial since they are larger than the average cat, and some Maine Coon owners have difficulty ensuring their cat is a healthy weight.
1st Maine Coon Growth Spurt
Their first growth spurt occurs at about 3 months old and lasts until they are about 7 months old.
2nd Maine Coon Growth Spurt
They have a second growth spurt soon after, usually around 8 months old.
3rd and 4th Maine Coon Growth Spurt
Finally, Maine Coons have their third and final growth spurt when they are about a year old, or around 50 weeks old.
After their final growth spurt, they will grow much more slowly, and finally stop growing altogether once they reach their full size between 3 and 5 years old.
Once a month, until your Maine Coon is about a year old, you should measure and track your cat’s measurements on a chart:
- Height
- Weight
- Length
This way, you can see if your Maine Coon is growing steadily, and you will have in-depth information to show your vet if you suspect something is wrong.
Keep in mind, though, that your Maine Coon’s growth probably will not look exactly like the guide above, so do not panic if it differs slightly!
Every Maine Coon is different, and they may experience growth spurts a little sooner or later than average.
What is most important is that your Maine Coon is growing steadily, without losing weight, and has enough energy to run, play, and hunt every day.
How Big Is The Average Maine Coon Cat?
If you have fallen in love with the Maine Coon breed due to its enormous size, you may be wondering, are Maine Coons always big?
The most popular Maine Coon stars typically weigh anywhere from 25 to 34 pounds, but the average Maine Coon weight can be very different.
So, how big does the average Maine Coon get?
When fully grown, most cats of this breed weigh between 8 and 25 pounds. In addition, they usually measure a length of about 40 inches and a height between 8 and 16 inches.
Furthermore, it is important to note that the female Maine Coon size is slightly smaller than males.
In general, though, there is nothing you can do to make your Maine Coon grow bigger, but there are some factors that may inhibit growth:
Stunted Growth
For example, young kittens who do not receive enough protein can experience stunted growth, and may not reach their full potential.
Illness Or Injury
Illness or injury at a young age, or being born the runt of the litter can all cause a Maine Coon to be smaller.
Genetics
Overall, though, the biggest factor in a cat’s size is genetics, and there is no way to know how big your Maine Coon will be until it reaches its full size naturally.

Female Vs Male Maine Coon Size
Many people are surprised to learn that female vs male Maine Coon size varies, but in actuality, this is also true for humans.
Many species of animals differ in size based on gender, sometimes in extreme ways.
When it comes to mammals, males are typically slightly larger on average than their female counterparts.
Over the years, some have posited that evolution has resulted in larger males as a way to overcome rival mates.
However, newer research suggests the hormone estrogen plays an important role.
When human ovaries begin producing estrogen around age 11 or 12, they contribute to bone growth.
Testosterone also contributes to bone growth in males.
However, estrogen causes the bones to fuse earlier than testosterone, leading females to be shorter, on average, than males.
As babies, human boys are usually a bit larger than girls on average. After a few months, however, both boys and girls grow at about the same rate.
Surprisingly, though, young girls typically have a major growth spurt around age 11 or 12, usually about two years before boys do.
As a result, adolescent girls are usually taller than boys for a couple of years, before they are surpassed in size.
By the time they turn 18, the average girl stands about 64 inches tall, or 5 feet 4 inches, while the average 18-year-old boy measures about 69.3 inches tall, or 5 foot 9.3.
Men and women also typically vary in weight, with the average 18-year-old girl weighing 125 pounds and the average 18-year-old boy weighing about 147 pounds.
Meanwhile, male Maine Coons are also typically quite a bit larger than female Maine Coons.
On average, a male Maine Coon will reach between 15 and 25 pounds fully grown and will stand between 10 and 16 inches tall.
Female Maine Coons, on the other hand, usually only weigh between 8 and 12 pounds, and measure a height of about 8 to 14 inches (sources 1,2).
