Ragdoll Cat Size Explained

Are Ragdoll cats bigger than normal cats? It is worth noting that this breed can be called the king-sized one. You can become an owner of the giant pet you love so much. Ragdoll size and weight depend on the sex of the cat but its color or patterns do not matter.

The female Ragdoll size is a little smaller than the males’ size. A full grown Ragdoll cat is 17-22 inches in length while its weight can be about 12-22 pounds.

Note that if the length is measured with the tail, your pet can be even more than 22 inches. If the Ragdoll female size can be up to 15-16 pounds, males can become real record-holders with their king-sized weight of 22-23 pounds.

According to the expert opinion, nutrition and training can trigger the size of your pet. Ragdoll cats have very strong skeletal systems and powerful muscles that can grow with the proper exercise plans.

This way the sturdy bodies by nature become well-built and hulking. Ragdoll cats seem larger visually due to their fur as well. Their coat is light but voluminous while complementing the voluminous body structure and long tail.

Ragdoll Kitten Development

This is the most common misconception that kittens of this cat breed are giant even when they are newborns. A baby Ragdoll is just 0.4-0.5 pounds. But these cats really grow very fast. The most significant development is seen in the period of the first month till seven/eight months.

The average kitten size chart starts with the weight your 2-week-old pet has. Let’s take a closer look at how parameters of the tiny buddy change:

  • 2-week-old Ragdoll kittens weigh just 0.5 pounds. Their tails and paws grow. The skeletal system turns to be firmer. The length of newborns is about 5-6 inches.
  • 3-week-old Ragdoll kittens continue to grow and can add 0.15-0.2 pounds and 0.5-1 inches for one week of their life.
  • 1-month Ragdolls weigh about 0.7-1.6 pounds. Their length becomes about 6-6.5 inches. Kittens are very playful at this age and require your care and love.
  • 6-week-old Ragdoll kittens have a weight of 0.8-1.7 pounds. They continue to grow in size, so their bodies, paws, ears, and tails become longer. If you are an owner of the shorthair ragdoll cat, you will likely don’t see changes in fur. But longhair kittens of this breed turn out to be fluffier in this period of time.
  • A 10-week-old Ragdoll kitten will show you a bounce in growth for sure. The young ragdoll cat size goes up to 2-2.5 pounds. Some kittens are up to 7 inches in length. This period is notable with the maximum curiosity of your pet.
  • 2-month Ragdolls can reach 7.5-8 inches in length with their long tails. The Ragdoll weight by age of two months is about 3 pounds.
  • A 3-month-old Ragdoll kitten will jump in size one more time because its dimensions will double in this period of time. The average length of a cat is about 8-9.5 inches. The weight is about 4 pounds.
  • The 4-month kitten weighs about 4.2-5 pounds. The length can stay the same or become 0.2-0.4 inches bigger.
  • The 5-month kitten weight is expected to be up to 6 pounds. The progress of most cats is well-visible.
  • The 6-month old cat size turns out to be 6-8.5 pounds (weight) and 11 inches in length. In comparison with other pets, Ragdoll cats do not have a time of crisis in this period of time.
  • 7-month ragdolls continue to grow, so their weight and length become bigger. The ragdoll cat size is notable with the increased dimensions. According to the breed characteristics, 12-13 inches in length and 7.5-9 pounds in weight.
  • 8-month kittens are almost full-grown Ragdoll breed males and females. The progressive growth stops, but the cat continues to increase its length (up to 14 inches) and weight (8-10 pounds) slowlier.

By the way, when are cats full grown? When do Ragdolls stop growing? It is difficult to answer in general. According to cat owners who keep track of the Ragdoll cat size, females and males of this breed can grow up to 1,5-2 years.

Factors That Could Trigger Size and Weight

Factors That Could Trigger Size and Weight


Experienced cat lovers state that the pet’s mental and physical health by nature is not about limits in its dimensions. There is a range of factors that matter when it comes to the Ragdoll’s size. First of all, king-sized cats of this breed are seldom females.

According to the TICA survey, gentle giants are usually male Ragdolls while fluffy girls are smaller with a record weight of 14-15 pounds.

Intake of supplements, high-quality food, and training can ruin stereotypes, and help your kitten grow into a beautiful cat with huge dimensions. If you are a cat owner and dream about a 15-pound cat or even a 20-pound one, find out more about factors that matter when it comes to the Ragdoll cat and its weight.

Colostrum Intake

This is a nutrient-rich food for newborns that boost their growth. If you adopt a small Ragdoll, do not neglect colostrum use. Remember that intake of this natural milk-driven food increases the Ragdoll cat weight and improves the immunity of kittens you got. If you do not want to make your buddy attackable by infections and illnesses, arrange colostrum intake.

Proper Diet & Nutrient Intake

Such arrangements like the purchase of litter boxes and toys are not so important as the regimen of your female or male ragdoll cats. You need to provide a proper diet that will be rich in nutrients (Ca, Zn, etc.) for the formation of healthy:

  • muscles;
  • bones;
  • joints.

Ragdoll owners should consult with the vet to plan the regimen with good food required for the growing body and exercise plan for training.


The temperament of Ragdolls is a little bit lazy and low-active. The task of cat owners is to provide the best conditions for regular training. Your pets are dog-like according to the opinion of experts. Find exercises that your buddy likes.
Some fluffies prefer to retrieve toys or play fetch as puppies do. Remember that Ragdolls are domestic cats (floor cats), so run and play with them indoors.


Note that the average cat size also depends on the physical health of your pet. The weight can increase or decrease if your ragdoll is ill. Some diseases provoke the size growth, others cause weakness and poor appetite. If you have just mentioned weight bouncing, visit a vet to prevent dangerous illnesses.

The King-Sized Cat Expectation

The King-Sized Cat Expectation

More and more owners would like to have a larger cat. Among the most demandable ones are Ragdolls too. Experienced breeders can provide helpful recommendations on how to select a kitten with the potential to become a king-sized grown buddy.

If the size matters to you, a 20-pound cat can be got from the best litter. But remember that these are only predictions. To meet your expectations, specialists can determine the average cat’s height, weight, and length.

Size Matters – Here’s Why

The battle between lovers of Ragdoll size vs normal cat dimensions continues. The desire to hug a huge pet and breed giant gentles often wins. But note three important aspects when it comes to Ragdolls:

  • You need to hold your buddy properly. Big cat breeds require more care. Remember that that size matters when you hold your Ragdoll. In order not to harm your pet, watch online tutorials and consult your vet.
  • Be sure that all the goods and accessories suit your pet. Do not forget to buy a scratching post and toys. Unfitting add-ons will not be appreciated by your fluffy friend. Ensure comfort and your love with the well-thought microclimate with all necessary things for your cat.
  • Be ready for bigger costs – king-sized breeds require more food, litter, attention. Toys (like scratching posts and balls) and clothes are larger as well. If you are not afraid of higher spending, it is not a challenge for you. If you have a limited budget (for food, cat show attendance, entertainment), think about bigger costs before adopting a Ragdoll kitty.
