Labradoodle Size Chart 24,000+ Weight Data Points on Toy, Mini, Medium, Standard, and Giant Labradoodles

In this article, you’ll find a Labradoodle size chart for Mini, Medium, and Standard Labradoodles. You will also learn about their growth patterns, and you’ll find links to our interactive Labradoodle puppy growth chart and calculator, which will predict how much your Labradoodle will weigh when full-grown!

How big will your Labradoodle get? The million dollar question. Unfortunately, the rumors are true – it’s nearly impossible to predict a Labradoodle’s exact adult size because they are mixed-breed dogs. That’s where we come in!

We personally know the worry and anxiety that comes with the uncertainty of how big a Doodle puppy will get. 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 Labradoodles:

Labradoodle Generations

A Labradoodle’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. 

Let’s take a quick look at the Labradoodle generations and what each of them means:

With each generation, we can achieve more control over a Labradoodle’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 Labradoodle, they can breed an F1b Labradoodle that has a Mini Labradoodle parent and a Miniature Poodle parent. 

Labradoodle Size Charts & Growth Patterns

Like most dog breeds, Labradoodles do their fastest growing in the first 50% of their adult weight. This typically corresponds to the first six months of puppyhood.

This is why it’s particularly important that your Labradoodle 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.

Labradoodle’s 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 Labradoodle size chart / graph shows the average weights by age (in weeks), by size of Labradoodle.

As of October 24, 2022, we’ve received over 40,000 accurate Labradoodle weight submissions through our calculator.

Mini and Medium Labradoodles

Mini Labradoodles generally reach half their adult weight between 3.5 and 5 months old. It will then plateau at its full adult weight between 11-13 months of age.

Like the Mini, Medium Labradoodles generally reach half their adult weight between 3.5 and 5 months old and will plateau between 11-13 months of age.

If you want to do a quick calculation, here’s the formula you would use to estimate the adult weight for both Mini and Medium Labradoodles:

Standard Labradoodle Size Chart

Standard Labradoodles generally reach half their adult weight between 4.5 and 6 months old. It will then plateau at its full adult weight between 12.5-16 months of age.

If you want to do a quick calculation, here’s the formula you would use to estimate the adult weight for Standard Labradoodles:

We hope this article gave you good insight into the different sizes of Labradoodles, their growth patterns, and the formulas you can use to predict their adult weights.
