Many breeds of dog reach physical maturity whilst they are still emotionally puppies. More often than not, they are fully grown whilst still displaying the mischievous traits of a toddler or have the stubborn know it all attitude of a preteen. However, is this the same with all dogs? More specifically is this the same for all sizes of Goldendoodle?
Mini Goldendoodles will typically reach their adult height between 6 and 8 months. Medium Goldendoodles at around a year and Standard between 12 and 18 months. They will then continue to gain weight for a few more months. Their height is measured from the paw to the shoulder.
Let us begin by exploring the size differences in the Goldendoodle breed and what size is considered to be fully grown.

What are the Different Sizes of Goldendoodle?
Typically, the Goldendoodle comes in three sizes. This is down to the Poodle also coming in three different sizes:
- Standard Poodle – Standard is the largest of the Poodle breed. To classify as a standard with the American Kennel Club, they must stand at over 15” at the shoulder. A male standard Poodle will generally weigh between 60lbs and 70lbs. His female counterpart 40lbs to 50lbs.
- Miniature Poodle – The Miniature Poodle is the middle child on the size scale. At the shoulder they should measure below 15” but greater than 10”. They weigh much less than the Standard Poodle averaging between 10lbs and 15lbs.
- Toy Poodle – The Toy Poodle is the smallest Poodle breed. At the shoulder they should be less than 10” in height. Weighing in at a tiny 4lbs – 6lbs, they really are a pocket pooch.
All three sizes of Poodle have the same proportions and build, they are simply just different heights and weights.
Golden Retrievers are of one standard size. The average male will weigh between 65lbs and 75lbs and measure between 23” and 24” at the shoulder. The female Golden Retriever is typically smaller at between 55lbs and 65lbs with an average height of 21.5” and 22.5”.
Based on these heights and weights are Goldendoodles similar in size and weight to their Poodle parent? Let’s take a look:
What Size is a Mini Goldendoodle?
The Miniature Goldendoodle is a cross between the Golden Retriever and either a Toy or Miniature Poodle. According to the Goldendoodle Association of America, the Mini Goldendoodle should stand at a height of over 14” but under 17”. They will typically weigh between 26lbs and 36lbs.
There is a slight cross over in the average height with the Miniature Poodle and are a good few inches taller than the average Toy. Their weight however is considerably more than both their Toy or Miniature parent. This is likely due to the influence of the Golden Retriever.
What Size is a Medium Goldendoodle?
The Medium Goldendoodle is more about the size of the parents than using a specific sized Poodle to breed with. Using the data from the Goldendoodle Association of America, the average weight of a Medium Goldendoodle is between 36lbs and 50lbs. Their height, in order to be classified as medium, should be greater than 17’ but smaller than 21”.
The Medium Goldendoodle is considered to be the most popular due to its size. A breeder will be able to provide you with the size of both the sire and dam. However, it’s important to remember that this won’t guarantee the size of their litter once fully grown. This means that there is always the possibility that your Goldendoodle may fall short (or tall) of the height ranges require to be classified as medium.
What Size is a Standard Goldendoodle?
The Standard Goldendoodle is a result of the Golden Retriever and a Standard Poodle. The height for classification as a Standard Goldendoodle laid out by the Goldendoodle Association of America is over 21”. This is 6” taller than the minimum height of the Standard Poodle.
The average weight of the Standard Goldendoodle is generally over 51lbs. Whilst this weight is similar to that of the average female Standard Poodle, it is less than the average male despite the height differences in the standards.
Are there any other sizes of Goldendoodle?
The Goldendoodle Association of America also classifies a Goldendoodle under 14” from paw to shoulder as a Petite Goldendoodle. They will typically weigh less than 25lbs.
If you are a lover of the Goldendoodle but do not have a lot of space at home, then there is also the Teacup Goldendoodle. Whilst the Goldendoodle Association of America do not have a specific height range classification for these tiny pups, they are typically smaller than 11” and weigh no more than 13lbs.
At What Age are Dogs Considered Adults?
Puppies become adult dogs anywhere between one and two years of age. Their bones will develop initially. Growth plates in their legs continually produce new tissue which calcifies and becomes bone. Once this process is completed, all tissue has hardened, and new tissue is no longer produced, at this point their bones will be their final size. They will then continue to develop muscle and fat until they reach physical maturity.
The size of the dog has a bearing on when they will be fully physically grown. They will also usually reach their full height before they reach their adult weight. The smaller the dog, the likelihood is that that they will reach their maximum height and weight sooner than a larger breed.
Small and medium dogs will typically reach their adult size in half the time of a larger breed. Small breeds will usually complete their growth by between 6 months and 8 months of age. Medium dogs will take a little longer but typically will have reached their adult height by around 12 months.
Larger breeds will reach their peak at around 12 to 18 months, but it can take up to two years to finish growing for the biggest dogs.
We have looked at the size varieties that Goldendoodles come in. We have also discussed how and when dogs in general reach adulthood in terms of size and weight. To knit this information together, we can conclude that the different sized Goldendoodle will reach physical maturity at different ages. Based on our findings your Goldendoodle will, on average, reach their full height dependent on what their final size will be:
- Mini Goldendoodle – The Mini Goldendoodle is classed a small breed dog. They will reach their adult height at between 6 and 8 months. They will continue however to put on weight, reaching their full adult weight at around a year old.
- Medium Goldendoodle – The Medium Goldendoodle will take longer to reach both their final height and weight. This will, on average, be around 12 months old for their height whilst they then continue to bulk out.
- Standard Goldendoodle – The largest of the Goldendoodle family will take the longest to reach their physical maturity taking up to 18 months to reach their final height. The next few months will be spent adding weight to their physique.
Does Paw Size Determine Dog Size?
Whilst not a definitive answer, it can be a good guide to look at your puppies’ paws to gauge their final height. Overly large or small paws could indicate that you will have a large or small adult dog.
Will the Biggest Puppy in the Litter Be the Biggest Adult?
No, not necessarily. It may be that they are the biggest pup because they are going to be the largest adult. Equally it could also be because they are big or strong enough to push their litter mates out of the way and consume the giants share of dinner.
