Cavapoo Size Guide: How Big Do Cavapoos Get?

Published Friday, March 18, 2022 by PremierPups

Cavapoos, or Cavoodle and Cavadoodle as some like to call them, are a gorgeous doodle breed that is created by crossing a Cavalier King Charles Spaniel with a Mini or Toy Poodle. These doodles puppies come in all kinds of stunning colors, shapes, and sizes. They can be Toy, Miniature, Standard, or even Teacup. The Cavapoo size can range anywhere from 9 to 12 inches in height and 8 to 20 pounds in weight. Aspects like their generation, gender, and parent breeds are a key factor in determining what the size of a full-grown Cavapoo will be. So how big does a Cavapoo get?  

Mini Cavapoo Size 

Mini Cavapoo puppies are the hybrid doodles of a Cavalier King Charles Spaniel crossed with a Miniature Poodle. These puppies grow up to be an average of their parents’ size. Mini Poodles weigh between 10 and 12 pounds and stand at 12 to 14 inches tall, while Cavalier adults weigh between 12 and 18 pounds and stand at 12-13 inches tall, so you can expect your full grown adult Mini Cavapoo to stand somewhere in between. Typically, the Miniature Cavapoo size is an average of 10 and 18  pounds and 12 to 14 inches.  

Toy Cavapoo Size 

Toy Cavapoos are bred by crossing a Cavalier King Charles Spaniel with a Toy size Poodle. Like the Mini Cavapoo, the size of the Toy Cavapoo is determined mostly by the size of the Poodle used in the mix. Toy Poodles weigh 4 to 6 pounds and stand at 6 to 8 inches when they reach adulthood. While Cavaliers are a bit larger than Toy Poodles, Toy Cavapoos are most often known to take after the size of their Poodle parent. That being said, you can expect your full-grown adult Toy Cavapoo to weigh as little as 7 pounds or as much as 13 and reach a height of 12 inches at most.  

Teacup Cavapoo Size 

Unlike Mini or Toy Cavapoos, Teacup Cavapoos are bred by crossing the smallest Cavalier King Charles Spaniel of a litter with a Toy Poodle. In this case, the size of the Cavalier is as important as the size of the Poodle. Some Cavapoo breeders select the smallest Cavalier, which is often referred to as the runt of the litter, in order to produce a Teacup size Cavapoo. In most cases, breeders steer away from this practice because the runt of a litter usually comes bearing health issues that are best not passed on to the offspring. For this reason, Teacup-sized Cavapoos are rare. To determine how big a teacup Cavapoo will get, the size of both parents must be known beforehand. Most commonly, the size of a full-grown teacup Cavapoo ranges between 5 to 10 pounds and 8 to 10 inches. 

Standard Cavapoo Size 

In some rare cases, Cavapoo dogs are bred by crossing a Standard Poodle with a Cavalier King Charles Spaniel. Standard Poodles are big dogs. They can weigh 40 to 70 pounds and reach as much as 22 inches in height when fully grown. Although this is not a common practice, standard Cavapoos that are bred using a large Poodle can be quite big themselves. The standard size Cavapoo can weigh 20 to 30 pounds or more and grow as tall as 18 inches at the shoulder. 

How To Predict the Size of a Cavapoo 

Typically, when looking to adopt a Cavapoo puppy, the Cavapoo breeder you are buying from will provide you with all the details you need about your new puppy. The breeder can tell you the size of the puppy’s parents as well as the estimated size of your puppy when it reaches maturity. There are also a few ways to determine the size of your Cavapoo on your own. A Cavapoo size chart can help you estimate the size of your full-grown Cavapoo, or you can do a simple equation to determine how big your Cavapoo will be. For example, if you have a Mini Cavapoo puppy, you should know that they stop growing at around 12 months. To determine the full size of a Cavapoo, you can look to its size at 4-5 months and double it to reach the estimated full-grown size. If your Mini Cavapoo weighs 6 pounds at 4-5 months, the equation will tell you that by the time it reaches adulthood, your dog will weigh 12 pounds. Toy Cavapoos on the other hand, can reach their adult size sooner at 7.5 or 11 months at most. You can weigh them at 3.5 months and double their pounds to determine their adult weight.  

Cavapoo Size Based on Gender 

Just like it is with every dog breed, the Cavapoo breed can have slight differences between the size of the male Cavapoo and the female Cavapoo. Males in every breed tend to have a sturdier, more robust build, while females are generally leaner and daintier. The difference between the male and female Cavapoos is not as obvious to the naked eye as it is with larger breeds. Typically, the size of the female Cavapoo is ten percent smaller than the size of the male Cavapoo. There is also the possibility that both female and male Cavapoos have the same size when fully grown. 

Cavapoo Size Based on Generation 

As one of the most popular small doodle breeds, the Cavapoo is bred through multiple generations, all of which can carry slight variations in size. The most popular Cavapoo generations are the F1, F1B, and F2

  • The F1 Cavapoo puppy is known as the first-generation Cavapoo. The F1 Cavapoos are the classic doodle puppies that are bred by crossing a Cavalier King Charles Spaniel with a Toy or Mini Poodle. This generation is 50% Cavalier and 50% Poodle. As mentioned above, the size of the F1 is determined by the size of the Mini or Toy Poodle parent.  
  • F1B Cavapoo puppies are known as the first-generation backcross. For the F1b Cavapoo generation, a puppy will be the offspring of an F1 Cavapoo backcrossed to a Mini or Toy Poodle. These puppies are smaller than the average mini or toy Cavapoos. 
  • F2 Cavapoo is known as the second-generation cross. F2 Cavapoos are the puppies of two F1 Cavapoos crossed. The size of the full grown Cavapoo puppies will be the same as the size of their F1 parents. Although their DNA is very similar to that of F1s, these puppies are most likely going to take after their parents’ size sporting the same coat type, colors, and physical features.  


Because Cavapoo puppies are created by crossing a Cavalier with a Mini or Toy Poodle, their size is always on the smaller end of the scale. Thanks to their adorable size, Cavapoo puppies fit wonderfully in any living setting. They are excellent for owners who live in apartments as well as for those who live in large suburban houses. Regardless of their size, Cavapoos are all about love, cuddles, and loyalty. They are devoted to their owners and make the best family dogs. Their petite size also makes them very easy to handle, care for, groom, and travel with.
