Maine Coon vs Ragdoll: Same Shortlist, Genuinely Different Cats
Which is bigger, which sheds more, which lives longer: the registry quotes and the measured studies, including the one sentence CFA copy-pasted between the two breeds.

The two most popular big fluffy cats in the West end up on the same shortlist in thousands of households. They are less alike than the photos suggest. The differences are documented in the registries' own words, including one sentence uses for BOTH breeds, verbatim.
Which is bigger? Measured: the Maine Coon
The internet's favorite question here has a measured answer, from a 2025 study of 56,169 cats (5,211 Ragdolls among them). It flagged the breeds sitting more than 10% above or below the all-breed median bodyweight:
Maine Coon bodyweight
flagged ↑
named above the all-breed median in the study's own results
Ragdoll bodyweight
not flagged
not named in either direction, in the largest sample ever assembled
's 20-pound sentence, both breeds
word for word
"it is not unusual for a mature male's weight to reach or exceed 20 pounds": identical on both pages
The registry ranges tell the same story politely. boxes the Maine Coon at 18-22 lb for males, against the Ragdoll's 15-20, overlapping at the edges. When the same registry recycles the same sentence for two breeds, stop using that sentence to choose between them. Both breeds' females run smaller; both take about four years to finish growing.
The coat: weatherproof armor vs silk pajamas
This is the cleanest structural difference, straight from the standards. The Maine Coon's coat is described by and in climate-adaptation terms: "heavy and water-resistant," built "for built-in protection from the cold," with snowshoe paws. The Ragdoll's CFA standard wants the opposite construction: "non-matting moderately long fur... abundant guard hairs and minimal woolly undercoat," and it PENALIZES a thick undercoat in the ring. Practical translation: the Maine Coon carries more coat, more undercoat and more seasonal wool to manage. The Ragdoll's silk-dominant coat runs lighter on maintenance (their shedding page vs the Maine Coon grooming guide).
The eyes: opposite rules
A detail that identifies mixes and settles arguments. Every show-standard Ragdoll must have blue eyes, in every color: no blue, no Ragdoll, per the standards. The Maine Coon rule is nearly the inverse: gold to green eyes, with blue PERMITTED only in whites and particolors. A blue-eyed brown tabby is possible in exactly one of these breeds (the Ragdoll, as a point).
Temperament: one "gentle giant" is official, the other borrowed
Both breeds are marketed as huge softies. The phrase belongs, officially, to one. 's own Maine Coon page calls it "the gentle giant of the cat fancy," and the phrase appears on no Ragdoll registry page we checked. What measured behavior research adds: the Ragdoll ranks among the LEAST active, most people-seeking breeds in two large owner-report studies, the lap-magnet profile. Maine Coon owners in the same literature report a more active, more investigative cat. 's own "similar breeds" field is one-directional here. The Ragdoll's page lists the Maine Coon as similar; the Maine Coon's page lists Norwegian Forest and Siberian, not the Ragdoll.
Lifespan: the same research program measured both
UK data measured both breeds, which makes this the rare comparison with matching methodology behind it. The Maine Coon's measured figure is 9.71 years. The Ragdoll's newest, breed-dedicated study puts median age at death at 12.85 years, with its authors noting the breed reads "largely typical for purebred cats." Both figures are UK. Both carry the caveat that fast-growing breed populations skew young. And both beat any uncited "12-15 years" boilerplate you will meet elsewhere.
Price: both premium, priced per market
Both breeds sit in the premium band, and a price is only real in its own market. Named rate cards and live samples for each are on the Ragdoll price page and the Maine Coon price page.

Frequently asked questions
Which is bigger, a Maine Coon or a Ragdoll?
The Maine Coon, per the largest measured comparison (56,169 cats): it is flagged above the all-breed median weight, the Ragdoll is not. Registry ranges overlap at the edges.
Are Ragdolls or Maine Coons more affectionate?
Both are people-oriented; measured owner-report studies place the Ragdoll among the least active, most contact-seeking breeds, the stronger pure-lap-cat profile, while the Maine Coon profile runs more active and investigative.
Do Maine Coons and Ragdolls get along?
No study measures this pairing; both breeds' registry portraits describe sociable, cat-tolerant temperaments, and introductions matter more than breed math.
Is a Ragdoll related to a Maine Coon?
No. The Maine Coon is a naturally-developed New England breed; the Ragdoll was founded in 1960s California from domestic longhairs. TICA lists them as "similar breeds" in one direction only.
Which sheds more?
The Maine Coon's standard-described double, weather-resistant coat carries more undercoat than the Ragdoll's guard-hair-dominant coat, which CFA penalizes for thick undercoat. Neither breed has an official shedding score.

This is information, not veterinary advice, and it cannot tell you what is wrong with your cat. Our rule is a simple one: if something is wrong with your cat, call your vet, and call an emergency clinic if it is out of hours. Nothing you read here is a reason to wait.
Medical information applies to every reader. Prices, legal duties and common practice do not: unless stated otherwise, they are given for the United States, and they differ in the UK, Canada and Australia, and often between states or provinces. Check with your own vet and your own local authority.
