Goldendoodle Size Chart For Toy, Mini, Medium, Standard, and Giant Goldendoodles

You’re probably wondering: how big will your Goldendoodle get? In this article, you’ll find a Goldendoodle size chart and learn about growth patterns for Goldendoodles. You’ll also find this link to our interactive Doodle puppy growth chart and calculator, which will predict how much your Goldendoodle will weigh when full-grown!

Goldendoodle Size Predictions

Now, you’ve probably heard that it’s pretty much impossible to predict exactly how each individual Goldendoodle puppy will grow. It’s true – because Goldendoodles are hybrids – a cross between the Poodle and Golden Retriever – each Goldendoodle’s genes will dictate how large or small it will be when full-grown.

This unpredictability might be leaving you feeling worried, anxious, or simply just curious. Luckily, we can take a “guesstimate” on your pup’s final adult weight based on observed growth patterns.

Let’s have a look at the typical size predictions of Goldendoodles:

*A dog’s height is measured from their withers, which is the highest part of their shoulder blades.

A Goldendoodle’s full-grown size is also determined by their generation. What does it mean exactly? Well, as we are combining two different purebred dogs, the generations are a great guideline that show us how much of the puppy’s genetic makeup consists of either of the parent breeds.

With each generation, we can achieve more control over a Goldendoodle’s size and other characteristics, such as their coat type and appearance. For instance, if a breeder’s goal is to achieve a smaller Mini Goldendoodle, they can breed an F1b Goldendoodle that has a Mini Goldendoodle parent and a Miniature Poodle parent. 

Goldendoodle Size Chart & Growth Patterns

Like most dog breeds, Goldendoodles do their fastest growing in the first 50% of their adult weight, which generally correlates to the first six months of life.

This is why it’s particularly important that your Goldendoodle puppy gets the correct nourishment they need to grow that adorable little body into a healthy adult one. Check out our guides on best dog food for Doodle puppies here.

They generally reach their maximum height by one year old but can spend a little longer gaining girth and weight. They generally finish growing anywhere between 1-2 years of age.

Speaking of, we’ve been collecting weight data from our Doodle Weight Prediction Calculator. The below Goldendoodle size chart / graph shows the average weights by age (in weeks), by size of dog.

As of October 24, 2022, we’ve received over 206,000 accurate Goldendoodle weight submissions through our calculator.

Toy Goldendoodles

Toy Goldendoodles generally reach 50% of their adult weight around 3.5 months old. They will then plateau at their full adult weight between 7.5-11 months of age.
