How Big Do Cockapoos Get? Full Grown Size Chart

Reviewed by

The Cockapoo dates back to the 1960s and many consider them to be the first designer dog breed. They are now extremely popular and are the third most popular dog breed in the US.

Cockapoos are classified as a medium-size breed, but there is a huge variation in their size.

In fact there are four different Cockapoo sizes.

Their size can range from 4 pounds to more than 20 pounds! Ranging from the tiny teacup all the way to the maxi, each and every one is unique, making them all the more charming and lovable.

Keep on reading to find out all about the four different sizes and how big full grown Cockapoos get. We also share puppy growth charts and size comparison charts…

How Big Do Cockapoos Get?

Cockapoo Size

Most Cockapoos will grow to be around 20 pounds and between 15 and 18 inches tall as adults. The tallest of them will likely reach around your knees, but most will grow to just below your knee level.

Mini is the most popular size, but there are also three more sizes.

The variation in sizes is easy to understand by dividing them into four categories. From smallest to biggest these categories are:

  • Teacup
  • Toy
  • Mini
  • Standard

No matter their height or weight all Cockapoos are classified as a medium-size breed, just like their Cocker Spaniel parent.

There are three types of Cocker Spaniel, but there is only a slight variation in their heights and weights. American, English working, or English show are all very similar in size. The main reason there are different sizes in Cockapoos is because of the Poodle parent!

Different Cockapoo sizes are named for the size of their Poodle parent. Toy, mini, and standard Cockapoos have toy, mini, and standard Poodle parents respectively.

As a cross breed there is no set breed standard.

This means that there is a large range of Cockapoo sizes. The teacup will always be the smallest of them all and the standard (sometimes called the maxi) is the biggest.

Even within a particular size category these dogs can differ in size greatly. If two puppies both have mini Poodle parents, one might be as much as four inches taller and five pounds heavier. This is because Cockapoos are mixed dogs with one parent a Poodle and the other a Cocker Spaniel.

First-generation mixed dogs vary greatly in size. It is not possible to 100% predict which traits they are going to get from which parent.

One Cockapoo might be more like their Spaniel parent with a slim, light frame. Another puppy might be more like their larger Poodle parent and weigh slightly more.

Teacup, toy, mini, and standard Cockapoos are not just different in size. They also have different temperaments too! Their energy levels, personalities, and general physical features will all be different.

For example standards and minis are much more energetic and love to play. Teacups and toys are much more affectionate lap dogs. That isn’t to say that the teacup doesn’t love a game of fetch, or the standard won’t love a snuggle… they are all adorable, loving, and playful.

Full Grown Cockapoo Size


Teacup Cockapoo

Teacup Cockapoos are the smallest of them all, weighing less than six pounds when fully grown. They also will grow to less than eight inches in height. As they are so tiny there is little room for variation in males and females. Because of this both males and females tend to be around the same size.

A teacup puppy at eight weeks of age will likely weigh less than a pound.

Luckily as they have so little growing to do, they will reach their full grown teacup cockapoo size by the age of eight months.

Teacup varieties are unique within the Cockapoo world because they are not named after the size of their Poodle parent. ‘Teacup’ comes from the fact that they are so tiny, some can actually fit inside a teacup.

There is some controversy with the term ‘teacup dogs’. Teacup puppies are bred by mating runts of different litters together. This often happens when a toy Poodle runt is bred with a Cocker Spaniel runt.

Their small size makes them rarer and more difficult to breed than the other Cockapoo sizes.

Breeding runts can also exacerbate health issues such as heart defects, digestive problems and liver shunts that are seen in small breeds.

Teacups can be as healthy as any toy-sized pup, but they must be bred responsibly over the course of a few generations.

If they are the smallest Cockapoo of the litter because of genetics, but are otherwise healthy, then breeding them together is likely to be fine.

If they were the runts of the litter because of underlying health condition (such as heart defects) then it is likely to increase the prevalence of these health problems in the breed.

The only thing that differentiates a teacup Cockapoo from a toy is that they weigh less than six pounds and are shorter than eight inches. It is possible for a toy and a teacup to come from the same litter!


Toy Cockapoo

Toy Cockapoos are just one size up from the teacup.

Full grown toy cockapoos weigh between 6 and 12 pounds and measure just 8 to 10 inches in height. Being so small, there is no noticeable difference between males and females.

At just 8 weeks old the Toy will weigh between one and two pounds. They will finish growing at around 8 to 12 months of age when they reach between 6 and 12 pounds.

If a Cockapoo is bigger than 10 inches tall they are instead categorized as a Mini. If a pup is smaller than eight inches they are a Teacup. The narrow window of Toy Cockapoo size ranges makes them a rare dog!

In order to consistently produce toy-sized puppies breeders will take a mini Cockapoo and breed them with a toy Poodle. These puppies are known as F1bs and their size will be much more predictable. Other features like how curly their fur is and their temperament will also be much more predictable.

F1 toy Cockapoos have one toy Poodle parent and one Cocker Spaniel parent. This means for F1 toy puppies there is not much consistency and they will often be a little bigger than most people are expecting.


Mini Cockapoo Size

Full grown Mini Cockapoos are between 13 to 18 pounds. Most grow to just below knee level and are covered in curly flowing coats, giving them a cute teddy bear appearance. The adult mini cockapoo size should range from 11 and 14 inches tall.

Minis are also called Miniature Cockapoos. They will weigh four to six pounds as puppies and will continue to grow until they are approximately one year of age.

Being larger than the teacup and toy sizes means minis have greater room for variation between sexes. This means that usually males are a couple of inches taller and a few pounds heavier than females.

The wider range of heights and weights they cover also means Mini Cockapoos are the most common and well known size.

Another reason they are particularly common is that they are produced by breeding a miniature Poodle with an English working Cocker Spaniel. By using a miniature poodle you get an apartment-friendly, cuddly and affectionate puppy who is also happy and sprightly.


Standard Cockapoo

The standard Cockapoo has a standard Poodle parent and a Cocker Spaniel parent. They are the biggest Cockapoo of all and because of this are also known as the Maxi.

Standard cockapoo size can range from 15 to 18 inches. They generally weigh around 20 pounds, although some individuals can weigh as much as 26 pounds. Males are usually bigger than females and some are up to five pounds heavier!

At 8 weeks old when you get your standard puppy they will weigh around seven pounds. This is more than a teacup Cockapoo fully grown!

Standard cockapoos are just as affectionate and loving as the other smaller sizes, but due to their size they don’t make great lap dogs. Their size won’t stop them trying to climb on and have a hug, but they are not as apartment friendly. Instead the teacup, toy, or mini might fit onto your lap more snugly!

Standards also need much more exercise and mental stimulation than the teacup, toy, or mini.

Cockapoo Size and Weight

The standard Cockapoo is the most unpredictable in terms of size and weight, however most will grow to be around 20 pounds in weight and 16 inches in size. A standard cockapoo full size can be from 15 to 18 inches tall and 20 to 26 pounds.

If you want a medium-sized dog who is goofy, energetic and loving then this size is perfect for you!

They are ideal for families who want a slightly bigger dog to play and cuddle with. Although just as loving and affectionate as their smaller siblings, their larger size means they might not be suited to those with very young children.

Miniature Cockapoos are quite a step down from the standard in terms of size. They stand between 11 and 14 inches tall and most adults weigh from 13 to 18 pounds.

They are a small breed that suits those with less space in their homes. Minis are particularly affectionate and loving lap dogs, who make great pets for those with young children as they are gentle and kind in nature.

Minis will need up to an hour of exercise a day. They are well suited to a household that wants a dog who can keep up with longer walks when they have more time at the weekends.

Toy Cockapoos, being only a few inches smaller than their Mini siblings, are also well suited to apartment living. However they are often just as energetic and need up to a one hour walk a day. This is especially true for Toy Cockapoos bred with a working English Cocker Spaniels parent.

Even though they tend to be only a bit smaller than the Mini, they can be less than half the weight. Those who might struggle to hold a dog that pulls hard on the lead might favor the Toy.

The teacup Cockapoo is the smallest of all and is a tiny dog breed. They must weigh less than six pounds and stand less than eight inches tall. The difficulties in breeding them means they can be expensive and rare.

How Big Will My Cockapoo Be?

Full Grown Cockapoo

Cockapoos will be around 20 pounds and between 15 and 18 inches when fully grown. Most will grow to just below your knees. The mini Cockapoo is slightly more popular than the standard and is the most popular size category.

Miniatures are between 11 and 14 inches tall. If you have a teacup or toy they will be even smaller. Teacups are the smallest of all four sizes and weigh less than six pounds.

Males generally weigh more and are taller than females, although this is usually only more obvious in the larger sizes like the Standard. There will be little to no difference in toy and teacup Cockapoos.

Different sizes of Cockapoos come from the variation in the Poodle parent.

Poodles come in several sizes. What Poodle is the parent to your puppy will have the biggest influence on his size.

The mini and toy Poodle when bred with a Cocker Spaniel will produce a mini or toy dog, respectively. A standard Cockapoo has a standard Poodle parent which will be much larger. The only one not named after their Poodle parents’ size is the Teacup.

Growth Table

Tracking your Cockapoo puppy’s growth is the best way to make sure they are growing up fit and healthy! Smaller pups will reach their adult size faster than larger ones. This is because they have less growing to do and it is common in all dog breeds.

The teacup will take just eight months to be fully grown, but the standard might still be growing at their 2nd birthday.

Use this handy chart to keep track of your puppies growth for their first year of life:

Cockapoo Adult Size Comparison Chart
Size2 months4 months6 months8 months12 months
TeacupUnder 1 pound2 pounds3 pounds4 pounds6 pounds
Toy1 pound4 pounds6 pounds9 pounds12 pounds
Mini4 pounds6 pounds9 pounds14 pounds18 pounds
Standard7 pounds9 pounds10 pounds15 pounds20+ pounds

Standard Cockapoos are the biggest and therefore take the longest to reach their adult size. They won’t stop growing until they are as old as 24 months.

Next the mini will stop growing at approximately 18 months and the toy will be fully grown by one year. The teacup will likely not grow much more after the age of eight months.

As a general rule of thumb most Cockapoos stop growing by their first birthday. After this they may continue to put on a little weight and ‘fill out’. At six months old they will measure roughly 50% of their full grown size.


The teacup, toy, mini and standard Cockapoo are all energetic, affectionate and loving dogs. No matter their size you can guarantee they will be adorable, affectionate, and an all-over lovable ball of fur!

Size is one of the few differences between these four dogs.

Teacups are the smallest and cannot be bigger than six pounds and eight inches. This dog is so small that only the Teacup Chihuahua is smaller than them! They are the only Cockapoo whose name is not based on the size of their Poodle parent.

Toy and Miniature Cockapoos are almost the same size. Standards are the biggest and their size can range from 20 to 26 pounds.
