Maltipoo Size Predictions

Maltipoo is an adorable hybrid breed of a Poodle and Maltese. So how big do Maltipoo dogs get? These cute Doodles weigh around 5 to 25 pounds and stand 6 to 14 inches tall from the withers, the highest part of a dog between the shoulder blades. We know, it’s a rather broad estimate… 

As with any other dog, we can predict a Maltipoo’s full size based on their parents’ size, their generation, mix, and gender. However, Maltipoos are usually a cross using Toy or Miniature Poodles, as the Maltese dog is a toy breed. So, knowing that, there are no Standard (large) Maltipoos.

Let’s now have a closer look at the Toy Maltipoos and Mini Maltipoos, their growth phases, generations, and estimated adult size.  

Maltipoo Size Charts & Growth Patterns

As Maltipoos are small breed dogs, they will usually reach their full size before they turn one year old. A general rule of thumb is that the smaller the dog, the sooner they’ll be fully grown.

The typical growth pattern of any puppy shows rapid growth in the first half of their puppyhood. Once they’ve reached half their size, growth will slow down a bit, and plateau in the last few months before they’re fully grown. By then, puppies have usually achieved their full height, but will continue to gain some girth. 

We recommend you give our Maltipoo size chart and growth calculator a go! Enter your pup’s estimated size, weight, age in weeks, and breed. Our calculator will predict your Maltipoo’s adult size and when they’ll reach it!

In addition, your Maltipoo pup needs an energy dense and nutritious diet as they grow up. Growing dogs require more nutrients and calories than fully grown dogs. Moreover, as Maltipoos come in toy and mini sizes, we recommend you opt for puppy formulas specially designed for small and toy breeds.

Like all breeds, Doodles are prone to certain types of hereditary diseases. We recommend you check out our overview of the most common Doodle health issues. For instance, Toy and Miniature Poodles are at a risk of developing patellar luxation or legg-calve-perthes disease that are both related to joint health. 

Furthermore, it’s important that we highlight how a proper diet is directly connected to your pup’s health and wellbeing. Over or under feeding can have serious effects on your Maltipoo’s health in both short and long term.

Mini Maltipoo

Mini Maltipoos weigh between 15 and 25 pounds and stand at 11-14 inches tall. This is the bigger version of a Maltipoo, which some breeders also call Medium Maltipoo. 

Usually, Mini Maltipoos reach half their full-grown size at around 3.5-5 months old, and reach their adult size around 11-13 months old. 

For a quick estimate, you can use this formula to predict your Mini Maltipoo’s full size by multiplying your pup’s weight at 18 weeks old by two.

Toy Maltipoo

Maltipoo toy size is usually around 5-10 pounds and 6-11 inches from the withers. Toy Maltipoo usually reaches half of their full size at 3.5 months, and adult size at 7.5-11 months of age. 

Additionally, you might have heard about Teacup Maltipoos, who weigh even less than 5 pounds. It’s important to keep in mind that even though Teacup Maltipoo size looks adorable, breeding dogs way too small will most likely have negative effects on the dog’s health.  

If you want to calculate the estimated size of a Toy Maltipoo once grown up, multiply their weight at 15 weeks old by two. 

F1 vs F1b vs F2b Maltipoo

We’ve briefly mentioned that your dog’s generations can also factor into their adult size. But how exactly? First, we need to understand what those generations mean and how they have been achieved.

  • An F1 or first-generation Maltipoo has a Maltese parent and a Toy or Mini Poodle parent. (50% Maltese, 50% Poodle)
  • An F1b or first-generation backcross Maltipoo has a Maltipoo parent and an original breed parent – usually a Poodle. (25% Maltese, 75% Poodle)
  • An F2 Maltipoo has a two F1 Maltipoo parents. (50% Maltese, 50% Poodle)
  • An F2b Maltipoo has an F2 Maltipoo parent and a Poodle parent. (25% Maltese, 75% Poodle)
Doodle Generations explained

Knowing that, we can predict that a Maltipoo’s size will be determined by their genetic makeup. For example, an F1 Maltipoo has a 50-50 chance of inheriting either more Poodle or more Maltese characteristics. In contrast, an F1b Maltipoo that’s been bred back with a Toy Poodle, will probably be a smaller dog and look more like a Poodle.

What Age Are Maltipoos Fully Grown?

Usually, a Maltipoo will reach its full size once it’s around 9-13 months old. Toy or Tiny Maltipoos usually reach their adult weight and size when they’re 9-11 months old. Miniature and Medium Maltipoos finish growing around 11-13 months of age.

Is A Maltipoo A Small Or Medium Dog?

Maltipoos are usually considered small dogs. Even though bigger Maltipoos do fall in the medium-sized breed category, they’re still on the lower end of the spectrum thanks to the Maltese dog and Mini or Toy Poodle parents.


In conclusion, Maltipoos are cute and bubbly small companions that everyone just adores.
