How Big Do Goldendoodles Get?

One challenge when you have a goldendoodle puppy is predicting how quickly they’re going to grow and how large they’ll be when fully grown. Let’s take a look at the factors that influence your puppy’s ultimate size and pass on some tips for guesstimating how big your standard, mini, or toy goldendoodle is going to get! 

Goldendoodle’s Vary In Size And Growth Patterns

Goldendoodles are the adorable and good-natured offspring of golden retrievers and poodles, but as a hybrid or mixed breed, it can be hard to predict how quickly or large a goldendoodle puppy is going to grow unless you know their lineage and the size of their parents:

  • Goldendoodles range from 50% to more than 80% poodle depending on their generation, and since they’re a breed that’s still being developed, there’s no set standards for their maximum or minimum sizes.
  • Goldendoodle puppies don’t all grow at the same rate or for the same length of time, either; a small doodle may be fully grown at 10 months, while a bigger pup may keep adding weight for more than a year.
  • It’s nearly impossible to predict which puppy in a litter will grow the fastest or reach the largest size from their appearance at 6 or 8 weeks of age; the largest puppy may end up being the biggest dog, but that’s not always the case.

How Many Sizes Of Goldendoodle Are There?

There’s no agreement on how many sizes of goldendoodle there are in the world. Breeders and organizations like the Goldendoodle Association of North America (GANA) recognize anywhere from 3 to 5 size-classes depending on their weight at maturity (or when full-grown):

  • The most common sizes are the mini goldendoodle, medium and standard, but some also produce smaller toy or petite doodles by breeding back to the toy poodle line, as you can see on the goldendoodle size chart below. 
  • The extra-small or “teacup” goldendoodle is also gaining in popularity, but they’re very rare, and there’s not as much known about their growth rate compared to the other more common sizes. It’s very difficult to produce a healthy dog with golden retriever genes that’s under 20 pounds!

Sizes Of Golden Retrievers And Poodles

As you can see, there’s a huge variation in goldendoodle weights and heights, and that makes sense when you consider the breeds they’ve descended from. You can learn more about their history in our detailed Care Guide, but here’s the basic facts about the goldendoodle’s parent breeds:

  • While goldens only come in a single size, they can range from 55 to over 75 pounds and usually stand 21 to 24 inches tall at the shoulders.
  • There’s also 3 distinct sizes of poodles, and your doodle may have several different types of poodles in their background. Poodles range from 4 to 70 pounds in weight and stand from 10 to more than 15 inches in height!
  • Golden retrievers and standard poodles also see differences in their adult weights by gender, since male dogs can be a bit taller and up to 20 pounds heavier than females.
  • For the smaller poodles and most goldendoodles, though, gender usually doesn’t have much effect on their adult size.

So your doodle’s size isn’t just determined by their generation and how much poodle they’ve inherited, it also depends on which size(s) of poodles they’ve been bred from. That’s why there’s so much variation in the size, weights and growth rates of goldendoodles!

How Big Are Goldendoodle Puppies?

Puppies typically go home when they’re about 8 weeks of age, although some breeders prefer to keep them for a few extra weeks and send them home at 10 or 12 weeks old. 8-week old goldendoodle puppies range from 3 to 12 pounds in weight, depending on whether they’re from a toy, mini, medium or standard line! 

How Quickly Do Goldendoodle Puppies Grow?

Goldendoodle puppies grow very quickly, and their most rapid phase and how long they grow just depends on their size. Smaller doodles usually have a slower rate of growth and reach their adult size earlier, while larger dogs may continue to pack on weight for more than a year.

By 8 weeks of age, most puppies have gained between 25 to 30% of their final adult weight. You can often make a reasonable estimate or “guesstimate” of a goldendoodle puppy’s adult weight by multiplying their weight at 8 weeks by 4.3

Using this equation, if you have an 8-week old goldendoodle that weighs 9 pounds, you can expect them to be about 39 pounds as an adult (9 x 4.3= 38.7)! 

Toy Or Petite Goldendoodles

The toy or petite goldendoodle stands about 14-inches tall and weighs less than 25 pounds when full-grown, which makes them easy to pick up and suitable for life in an RV or apartment. 

  • They usually weigh between 3 and 6 pounds at 8 weeks of age and typically gain about 1 to 5 ounces a week.
  • Their most rapid phase of growth is in the first 11 weeks of life, and it tapers off as they reach maturity at 8 to 11 months of age. 
  • Toy goldendoodles usually reach the halfway or 50% mark in their growth at around 3 to 3.5 months (12 to 16 weeks).

Miniature Or Mini Goldendoodles

Mini goldendoodles range from 14 to 17 inches tall and usually weigh between 26 and 35 pounds as adult dogs. This is an ideal size for families with older kids, apartment dwellers and folks who want a small but exciting companion!

  • Mini’s usually grow a bit faster than the toy-sized puppies, and add about 5 to 8 ounces a week during their first 11 weeks of life.
  • They grow most rapidly in those first 11 weeks, but they continue to grow and gain weight for about 11 to 13 months on average.
  • Mini goldendoodles are usually half-grown at 3.5 to 4 months (16 to 20 weeks).

Medium Goldendoodles

Medium goldendoodles are the most popular size, and it’s not hard to see why. These teddy bears stand from 17 to 20 inches tall and weigh 36 to 50 pounds, making them the ideal-sized doodle for active families.

  • Medium and standard goldendoodles can overlap a lot in size at 8 weeks of age, so it’s not always possible to distinguish them from each other as puppies. Medium doodles usually grow a little slower than standards and stop growing a few months sooner.
  • Medium doodles typically gain about 1 to 2 pounds a week during their first 16 to 20 weeks of life, but it slows down after that. They reach their maturity at 11 to 13 months.
  • They’re usually about half or 50% grown when they’re 4 to 5 months of age (16 to 20 weeks).

Standard Or Large Goldendoodles

If you want a large goldendoodle that stands more than 20 inches tall and can weigh from 50 to more than 90 pounds, then you’ll be looking for a standard size puppy! These big dogs are ideal for any family with the room to accommodate their bounding and energetic playstyle.

  • Standard goldendoodles usually range from 9 to 12 pounds at 8 weeks of age, although some slower-growing standard puppies may be a little smaller at first and resemble a medium doodle.
  • These large dogs grow at a rapid pace and gain about 1.5 to 2.5 pounds a week, and they often have spurts where they grow even more rapidly. They’ll grow steadily until they’re 18 to 24 weeks old, when the rate slows. Standard puppy’s usually hit their adult height at around a year, but may keep adding weight until they’re 16 months old!
  • Standard goldendoodles may not reach the halfway mark in their growth cycle until they’re 4.5 to 6 months old (18 to 24 weeks)! Adult males are often a little larger than females, but there’s not a significant difference in their size or weight by gender.

What Influences Your Goldendoodle’s Adult Size?

Your puppy’s growth and eventual adult size are governed by a host of variables and influenced by both genetic and environmental factors, but they don’t all play an equal role. For instance, a puppy’s growth can be stunted through poor or inadequate nutrition, but the specific diet they’re fed doesn’t usually play a huge role in their final size. Proper nutrition just helps them reach their maximum potential. 

The main factors that influence your puppy’s size are:

  • Generation of Goldendoodle (genetic)
  • Size of Parents (genetic)
  • Diet and Nutrition (environment)
  • Gender (genetic)
  • Age at time of Spay/Neuter (environment)

If you want to know how large your goldendoodle’s going to be, it’s best to consider the size of their parents and their generation. Beyond the first unpredictable pairing of a poodle and golden, goldendoodles usually fall in between their parents in size, and breeders can often predict the maximum size of their puppies.

Male dogs may grow significantly bigger than females in some breeds, but for goldendoodles there doesn’t seem to be a strong correlation between their adult size and gender. But doodles that are surgically altered (spayed/neutered) prior to reaching sexual maturity may end up growing taller, so talk with your vet about the optimal timing for your dog’s surgery.

Conclusion: What Size Goldendoodle Should You Get?

If you’re worried about your doodle outgrowing your home, or if you live in an apartment with weight or size restrictions, you’re probably best off working with a breeder instead of adopting a puppy with an unknown lineage. 

It’s difficult to predict how large a goldendoodle puppy will grow, although their weight at 8 weeks can help you make a rough guesstimate of their final adult weight.
