Persian vs Ragdoll: The Face Contract or the Size
Two calm longhairs, two very different daily contracts: the Persian's flat-face file and daily comb against the Ragdoll's size and its heart-test paperwork. Compared from the sources.

Put a Persian and a Ragdoll on the same sofa and you have two of the calmest, most deliberate lap cats the fancy makes, both longhaired, both quiet, both people-oriented. The choice between them is not a temperament choice. It is two different daily contracts: the Persian brings the flat-face file and a coat that demands a comb every single day; the Ragdoll brings substantially more cat, a lighter coat contract, and a heart-test line on the paperwork that a good breeder will show you unasked.
Size: the Ragdoll is simply more cat
The Ragdoll side has registry numbers: boxes it at roughly 10 to 15 lb for females and 15 to 20 lb for males (4.5 to 6.8 / 6.8 to 9 kg), one of the largest boxed ranges in the fancy. The Persian side is the interesting absence our research kept: no registry we read publishes a Persian weight range at all, and the measured reality is modest, a mean of 3.9 kg (8.6 lb) across 3,235 UK Persians in the O'Neill 2019 primary-care cohort. The visual bulk of a Persian is coat; the bulk of a Ragdoll is cat.
The face: the Persian's file, and only the Persian's
The Persian is a brachycephalic breed, and our profile carries it as a three-tier file rather than a blanket: the doll-face and moderate cats on one side, the extreme show face on the other, with the measured tenfold respiratory finding scoped to the EXTREME tier only, exactly as the study states it, and 's own moderate-versus-extreme line quoted. Daily eye wiping for tear staining is part of the contract at every tier. The Ragdoll has no flat-face file: its head is a broad modified wedge, and everything that follows from a flat face (the eye care, the anesthesia conversation) stays in the Persian column.
Coat: daily, versus a few times a week
Both are longhairs; the contracts differ by a factor of daily. The Persian's full coat with its woolly undercoat is the fancy's canonical daily-comb coat: skip days and it mats. The Ragdoll's semi-long coat carries less undercoat by its own standards' description and asks for a few sessions a week. If ten minutes of grooming every day sounds like a ritual you will love, that is a vote for the Persian; if it sounds like a chore you will skip, the mats will find you, and the Ragdoll is the honest pick.
Health paperwork: two DNA tests, two organs
The buyer's question differs by breed, and both have a clean, testable answer. The Persian file leads with PKD (polycystic kidney disease): the DNA test exists, carriage has fallen dramatically since testing began, and the question for a breeder is both parents' PKD status. The Ragdoll file leads with (hypertrophic cardiomyopathy): the breed carries a named mutation ( R820W) with a DNA test that has made a dated condition of registration, and the question for a breeder is the parents' R820W results. Kidneys on one side, heart on the other; on both sides, a named test a reputable breeder expects to be asked about. Neither file is a reason to avoid either breed; both are a reason to buy from someone who tests.
Lifespan: overlapping, honestly
The quoted ranges overlap almost entirely: the Persian's registry span runs 8 to 16 years (the span of disagreeing registry claims, each attributed on our profile) with a measured 13.5-year median; the Ragdoll's quoted 12 to 17 carries a measured 12.85 years beside it. The measured anchors sit a few months apart, from different cohorts. We print both and call it what it is: not a deciding axis.
Temperament: genuinely not the tiebreaker
Our Persian profile reads "composed, quiet, routine-loving"; the Ragdoll's registry portraits say "relaxed, affectionate, low-activity, quiet." These are the same shelf of the personality library. The practical difference buyers report is carry-ability and floppiness folklore on the Ragdoll side, which its own registries describe as a tendency, not a guarantee. If you want a decisive temperament contrast, this pairing will not give you one; pick on the face, the coat contract and the size instead.

Frequently asked questions
Are Ragdolls Persian cats?
No. The Ragdoll was founded in 1960s California from cats the registries themselves describe as domestic longhair/Angora-type; a Persian connection appears only in one period-authored community FAQ, and no registry account confirms it. The two are separate breeds with separate standards everywhere.
Which is better, a Ragdoll or a Persian?
Neither, and the honest version of the question is: which contract fits your life? Daily combing and the flat-face care file, in a smaller, quieter package (Persian), or more cat, a lighter coat routine and a heart-test line on the pedigree paperwork (Ragdoll). Temperament will not decide it: both are calm lap companions.
Which is bigger?
The Ragdoll, by a wide margin: TICA boxes males at 15 to 20 lb (6.8 to 9 kg), while the measured Persian mean is 3.9 kg (8.6 lb) across 3,235 UK cats, and no registry publishes a Persian range at all.
Which sheds or mats more?
The Persian's full, woolly-undercoated coat mats within days without a daily comb. The Ragdoll's semi-long coat is the lighter contract: a few sessions a week.
Do they have the same health tests?
Different ones, same logic: PKD1 for the Persian, the R820W HCM mutation for the Ragdoll. Both are DNA tests a reputable breeder runs on the parents and shows you without being pushed.

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.
