Discover how large Maine Coon cats really get, how they compare to other breeds, and what their size means for care and daily life.

The Maine Coon holds a special place in the feline world for its impressive size, majestic presence, and affectionate personality. As one of the largest domesticated cat breeds, Maine Coons inspire both awe and adoration among cat lovers. This comprehensive guide unpacks everything you need to know about Maine Coon cat size—from average measurements and growth stages, to size comparisons with other breeds, and what their size means for your daily life and care routine.
What Makes the Maine Coon Unique?
The Maine Coon is recognized as America’s oldest native cat breed and the official state cat of Maine. Renowned for their rugged build and gentle temperament, these cats are affectionately called ‘gentle giants’. Maine Coons command attention with their:
- Large, muscular frames
- Thick, shaggy double coats
- Long, bushy tails
- Large, tufted ears reminiscent of a bobcat
- Friendly, dog-like personalities
While their substantial size is a standout feature, Maine Coons are beloved for their affectionate nature, intelligence, and compatibility with families, singles, and other pets alike.
Average Maine Coon Size: Height, Weight, and Length
General Measurements
Maine Coons are among the largest domesticated cats, with males generally larger than females. Here’s an overview of their typical size at adulthood:
Sex | Weight (lbs) | Height (inches) | Body Length (inches) | Tail Length (inches) |
---|---|---|---|---|
Male | 15 – 25 | 10 – 16 | 19 – 30 | 12 – 18 |
Female | 10 – 15 | 8 – 14 | 19 – 30 | 12 – 18 |
Some exceptionally large males can weigh up to 30 pounds or more, though this is rare and often unhealthy.
Comparing Maine Coon Size to Other Breeds
To appreciate just how big Maine Coons are, let’s see how they compare with a typical domestic cat:
Feature | Maine Coon | Average Domestic Cat |
---|---|---|
Weight | 10 – 25 lbs | 8 – 10 lbs |
Height (shoulder) | 10 – 16 in | 9 – 10 in |
Length (nose to tail base) | 19 – 30 in | 15 – 20 in |
Tail Length | 12 – 18 in | 9 – 10 in |
The Maine Coon’s substantial length and muscular build easily set it apart as one of the world’s largest pet cats.
Growth Timeline: When Does a Maine Coon Reach Full Size?
Unlike many cat breeds that reach full size within a year, Maine Coons grow slowly and steadily, often not reaching their adult size until they are 3 to 5 years old. Here’s what to expect during their growth phases:
- Kitten (0–6 months): Rapid growth period. Kittens may double in size every few weeks.
- Junior (6–12 months): Growth slows, but bones and muscles continue developing.
- Adolescent (1–2 years): They approach their adult height and length, but continue to fill out.
- Adult (3–5 years): Reach full size, especially in weight and muscle mass.
Maine Coons maintain a sturdy, athletic frame throughout their lives, with males generally growing larger than females.
Maine Coon Physical Appearance and Characteristics
- Coat: Long, thick, and water-resistant double coat. The fur is longer on the ruff (neck), underbelly, and tail.
- Head: Slightly squared muzzle with prominent cheekbones.
- Ears: Large, wide at the base, and often topped with lynx-like tufts.
- Eyes: Large and expressive, with colors ranging from green, gold, copper, blue, or odd-eyed (one blue, one gold/green).
- Build: Muscular, broad-chested, and rectangular body shape. Legs are strong, and the paws are large and tufted.
- Tail: Long, bushy, and flowing—often as long as the body itself.
Why Are Maine Coons So Big?
Several factors contribute to the Maine Coon’s legendary size:
- Genetics: Selective breeding for size, strength, and hardiness in the harsh New England climate.
- Adaptation: Evolutionary adaptations for survival, such as a thick coat and large paws for snow.
- Slow Growth Rate: Longer development period allows for larger, more muscular growth.
There’s no scientific evidence that Maine Coons are part raccoon or bobcat, despite many charming legends. Their size is due to natural and selective breeding within domestic cat populations.
Implications of Large Size: What Does It Mean for Owners?
Health and Longevity
- Life Expectancy: Generally 12–15 years, though many live beyond this with proper care.
- Common Health Issues: Hypertrophic cardiomyopathy (HCM), hip dysplasia, and obesity if overfed or under-exercised. Regular vet checkups are crucial.
- Weight Management: Obesity is a risk for large cats. Maintain a healthy diet and regular exercise.
Daily Care Requirements
- Grooming: Their thick coats require regular brushing (several times a week) to prevent matting and reduce shedding.
- Space: Large cats benefit from ample living space and sturdy furniture—look for reinforced scratching posts and cat trees designed for big breeds.
- Diet: Quality high-protein foods formulated for large or active cats.
- Activity: Maine Coons are playful and energetic. Schedule daily play sessions to stimulate them both physically and mentally.
Maine Coon Size Myths and Realities
Myth: All Maine Coons are gigantic.
Reality: While they’re larger than the average cat, sizes vary, and not all individuals are massive. Genetics, diet, and health affect ultimate size.
Myth: Maine Coons keep growing their entire lives.
Reality: They grow longer than most cats but typically stop gaining size after 3–5 years.
Maine Coon Size: Male vs. Female
Male Maine Coons are generally larger and heavier than females, though both are considerably bigger than most domestic cats.
Sex | Weight (lbs) | Height (inches) | Length (inches) |
---|---|---|---|
Male | 15 – 25 | 10 – 16 | 19 – 30 |
Female | 10 – 15 | 8 – 14 | 19 – 30 |
Despite the size difference, both male and female Maine Coons share similar temperaments—gentle, friendly, and sociable.
How Maine Coon Size Affects Living Arrangements
- Sturdy Furniture: Invest in durable, large cat trees, reinforced scratching posts, and wide beds to accommodate their size and energy.
- Litter Box: Choose a jumbo-sized litter box to provide ample space for comfort.
- Transportation: Use extra-large carriers for vet visits or travel.
Maine Coons adapt well to both houses and apartments, but benefit from vertical and horizontal space for exercise and play.
