How Big do Cockapoos Get? Teacup, Toy, Mini, & Standard

September 24, 2022

Are you looking for a new furry family member? A Cockapoo can be an excellent choice for would-be pet parents.

But before you commit to a specific dog breed, you will want to spend some time researching your options to understand which dog breed will best fit your family. This is particularly the case if you choose a mixed breed such as a Cockapoo.

One factor to consider is how big your new canine companion will be once fully grown. This can make a big difference for many dog owners as larger dogs are not well suited to apartment living or smaller spaces.

Today we will be covering what size each type of Cockapoo is once fully grown and the factors that can play a role in their adult size.

Cockapoo Size Fully Grown

If you are new to this popular cross-breed, it may come as a surprise to learn that they come in four different types. This ranges from tiny teacup Cockapoos all the way up to the far larger standard or maxi Cockapoos.

As you may glean from the names, the key difference between the types of Cockapoo is their size. Let's take a look at each type to understand just how different the sizes of Cockapoo can be.

Teacup Cockapoo Size

The Teacup Cockapoo is the smallest of all four dogs. It came from mating a Toy Poodle or Teacup Poodle with a smaller Cocker Spaniel and then continually breeding the smallest dogs in the litter. Over time, this results in smaller and smaller dogs.

As you may imagine, the result is a pretty small dog. Fully grown a Teacup Cockapoo will only weigh 2.7kg and measure around 10 inches in height.

Teacup Cockapoos can be quite hard to find. You may need a little patience if you are looking for this tiny designer dog breed.

Teacup Cockapoo Average Size and Weight:

  • Height: 10 inches (25 cm)
  • Weight: 2.7kg (6 lbs)

Toy Cockapoo Size

Toy Cockapoos are a little bigger than Teacup dogs. Not in height, they are also around 10 inches tall. Where this type of Cockapoo differs is its weight which is double that of a Teacup.

They weigh 5.4 kg when fully grown. This makes the Toy dogs have a bit of a stockier appearance which is how you will be able to tell this type of Cockapoo apart from the Teacup.

Toy Cockapoo Average Size and Weight:

  • Height: 10 inches (25 cm)
  • Weight: 5.4 kg (12 lbs)

Miniature Cockapoo Size

A Miniature Cockapoo is again a bit larger than the Toy and Teacup dogs. This time both in height and weight.

On average, a Miniature Cockapoo will weigh 8 kg and be 13 inches tall. This can vary a little though going between 11 and 14 inches in height and between 5.9 and 8 kg in weight.

The size of their parents and the parent dogs and the amount of Cocker Spaniel and Poodle in your Cockapoo will determine a lot of this. They are still small enough to be comfortable living in a smaller home, providing they get a lot of outdoors time.

Miniature Cockapoo Average Size and Weight:

  • Height: 13 inches (33 cm)
  • Weight: 7.5 kg (18 lbs)

Standard/Maxi Cockapoo Size

A Standard or Maxi Cockapoo is the largest of the lot and is bred by combining a standard Poodle and a normal-sized Cocker Spaniel. They are also the most common type of Cockapoo you will see.

Standard Cockapoos are 15 inches tall and weigh at least 8.5 kg. That is the minimum height and weight requirement for a dog to be classed as a Maxi Cockapoo. Less than that will place your dog into the Miniature Cockapoo category.

Standard Cockapoo Average Size and Weight:

  • Height: 15 inches (38 cm)
  • Weight: 8.5 kg (19 lbs)

What is the Average Size of a Cockapoo?

The average size of a Cockapoo will vary depending on the type as outlined above. Toy and Teacup Cockapoos will end up as far smaller dogs while Miniature and Maxi dogs are a bit larger.

This means there would be a huge height and weight range to consider if you are looking at all four dogs, which would be:

  • Weight: 2.7 - 8.5 kg
  • Height: 10 - 15 inches

That is a huge range! It is better to look at the type of Cockapoo you have and compare your dog to the average sizes of their type.

When is a Cockapoo Fully Grown?

Most Cockapoos will achieve their adult height by around nine months old but will continue growing in weight until they are around one year old. Males generally continue to grow even after this as they have more muscle mass to put on.

Different types of Cockapoo will grow at their own rates depending on what their adult weight will be. A smaller dog may appear like they are not growing so quickly, while bigger dogs have much more ground to cover in the first year.

What can Affect the Size a Cockapoo Grows to?

The size of your Cockapoo as an adult will depend on several factors. Points to consider include the type of Cockapoo you have, genetics, the size of your dog's parents, what your feed your Cockapoo, their health, and how much you exercise your dog.

Also, as a cross breed, the amounts of each of the parent breeds present can also affect Cockapoo size. Cocker Spaniel and Poodle also both have their own size ranges. You never know what you will get with a mixed-breed dog.

Let's take a look at each of these factors in a little more depth.

Type of Cockapoo

First, as discussed above, there are different types of Cockapoo with Teacup, Toy, Miniature, and Maxi Cockapoos. Which type of dog you have will determine a lot about your Cockapoo.

This is likely to be the most impactful factor when it comes to adult size. You will now already know that there are big differences between the smallest and largest Cockapoos. Remember to keep in mind the expected adult size for their type before considering any other reasons for their size.


All dog breeds have a range that indicates how big an adult's weight and height should be. If the puppy's parents are both on the smaller side of their respective ranges, they will be very likely to produce smaller dogs.

Also, Poodles are larger than Cocker Spaniels so if your puppy has more Poodle than Cocker Spaniel in the mix, it's more likely you will have a larger dog.


All puppies have a lot of growing to do, and you must give your dog a solid diet of high-quality protein-rich dog food to ensure they have everything they need to become strong and healthy dogs.

Malnourished pups are less likely to have everything they need to reach their full potential.


The most common reason your Cockapoo puppy's growth could be affected due to health is from intestinal worms such as hookworms or roundworms.

These worms steal nutrients and calories from your dog, leaving them not enough fuel for all that growing they need to do.


Exercise only makes the list in reference as if your Cockapoo doesn't get enough of it it can become overweight. This would result in your Cockapoo being far heavier than expected, along with impacting their health.


Cockapoos come in a broad range of sizes with four distinct types to choose from. They range from the tiny, aptly named Teacup Cockapoo all the way up to the Standard Cockapoo, which is considerably larger!

This means no matter your preferences, there will be a Cockapoo for you. They make great companion dogs which is no surprise as it's why these companion dogs were originally bred.

Also, no matter which type of Cockapoo you choose, make sure you find a reputable breeder for your new furry friend. Just like it's important to take your time to research which dog is best for you it is also important to make sure you have a good breeder. Take time to ask lots of questions and make sure they are not just trying to breed designer dogs for money.

Any good Cockapoo breeder will be delighted to hear an owner taking such a strong interest in the health of their new Cockapoo puppy.

All four sizes of Cockapoo are still classed as small dogs. Even the Maxi Cockapoo just misses the cut for being classed as a medium-sized dog! There is not much in it though.
