How big do Goldendoodles get? Full size guide by type
Goldendoodle size is determined almost entirely by the Poodle parent. The same friendly doodle personality shows up at 20 lbs and at 80 lbs. Here is exactly what to expect by size class and how to predict what your puppy will become.
What determines Goldendoodle size
Golden Retrievers are a consistent size: females average 55 to 65 lbs, males 65 to 75 lbs. Poodles, however, come in three distinct size classes: Toy (under 10 lbs), Miniature (10 to 20 lbs), and Standard (40 to 70 lbs). The Poodle parent determines what size class the Goldendoodle will fall into.
The exact weight within a size class depends on which individual parent it takes after more, the specific weight of the Poodle used, and random genetic variation between littermates. Two puppies from the same litter can differ by 10 to 15 lbs at full size.
Goldendoodle size chart
| Size Class | Adult Weight | Height at Shoulder | Poodle Parent Used | |
|---|---|---|---|---|
| Toy / Petite | Under 15 lbs | Under 13 in | Toy Poodle | |
| Mini | 15 to 35 lbs | 13 to 20 in | Miniature Poodle | |
| Medium | 35 to 50 lbs | 17 to 21 in | Large Miniature or small Standard Poodle | |
| Standard | 50 to 75 lbs | 20 to 24 in | Standard Poodle (medium sized) | |
| Large Standard | 75 to 90 lbs | 22 to 26 in | Standard Poodle (large line) |
When do Goldendoodles stop growing?
Most of a Goldendoodle's height is reached by 10 to 12 months. Weight continues filling in for several months after that, especially in standard size dogs.
| Size Class | Reaches Full Height | Reaches Full Weight | Notes | |
|---|---|---|---|---|
| Mini (15 to 35 lbs) | 9 to 11 months | 10 to 12 months | Fastest to mature | |
| Medium (35 to 50 lbs) | 11 to 13 months | 12 to 14 months | Mango reached full weight at 13 months | |
| Standard (50 to 75 lbs) | 12 to 15 months | 14 to 18 months | Can look lanky until weight fills out |
How to predict adult size from a puppy
The most accurate method is to look at both parents. If the breeder lets you meet the Poodle parent and the Golden Retriever parent, their combined weights give you a range. Most offspring fall somewhere between the two parents or toward the Poodle side (since most Goldendoodles are F1B and carry more Poodle genetics).
A commonly used formula for medium and standard Goldendoodles: take the puppy's weight at 16 weeks and multiply by 2. This gives a rough adult weight estimate. For Minis, the formula is less reliable due to faster early growth rates.
Another formula sometimes used: (puppy weight at 8 weeks) x 4 for standard Goldendoodles, or check the weight at 12 weeks and multiply by 2.5 to 3. These are all approximations. Individual variation is significant.
Puppy weight by age (medium Goldendoodle reference)
| Age | Approximate Weight | Notes | |
|---|---|---|---|
| 8 weeks | 8 to 12 lbs | Going home weight range for most medium doodles | |
| 12 weeks | 14 to 20 lbs | Visible size difference from week 8 | |
| 4 months | 20 to 28 lbs | Growing fastest in this window | |
| 6 months | 28 to 38 lbs | Close to adult height, weight still adding | |
| 9 months | 35 to 44 lbs | Most adults within a few pounds of full weight | |
| 12 to 14 months | 38 to 50 lbs | Full adult size range |
Size vs generation
Generation (F1, F1B, F2) does not directly control size. What matters is which Poodle was used. An F1B Mini Goldendoodle is smaller than an F1 Standard Goldendoodle, not because of the F1B designation but because a Miniature Poodle was used in the backcross.
Generation matters for coat, shedding, and genetic predictability. Size is about the Poodle parent first, the individual genetics second.
Standard vs medium vs mini: which size is right?
There is no universally correct answer. The right size depends on your living situation, activity level, and personal preference.
Standard Goldendoodles are better suited for large homes, active families, and people who want a dog sturdy enough for long hikes, rough play with bigger kids, and outdoor activities. They are harder to manage at the vet and groomer and cost more in food and grooming.
Medium Goldendoodles work for most households. They handle most activities comfortably, are easy to manage in cars and on walks, and cost less to groom than standards. This is the most popular size class.
Mini Goldendoodles are best for apartments, smaller homes, families with young children who prefer a less physically overwhelming dog, and owners who travel frequently. They live slightly longer and cost less per grooming appointment, though puppy prices tend to be higher due to smaller litter sizes.
