Labradoodle Size Chart for Mini, Medium, and Standard Labradoodles

Pin It!

How big will your Labradoodle get? The million dollar question. Unfortunately, the rumors are true – it’s nearly impossible to predict an LD’s exact adult size because they are mixed-breed dogs. That’s where we come in! In this article, you’ll find a Labradoodle size chart for Mini, Medium, and Standard Labradoodles. You will also learn about their growth patterns, with links to our interactive Doodle puppy growth chart and calculator, which will predict how much your Labradoodle will weigh at full-grown!

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:

 Miniature LabradoodleMedium LabradoodleStandard Labradoodle
Weight15-25 pounds25-50 pounds50-90 pounds
Height13-17 inches tall at the shoulder17-20 inches tall at the shoulder20-26 inches tall at the shoulder
When Full-Grown?11-13 Months11-13 Months12.5-16 Months

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. LD’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.

Labradoodle Size Charts & Growth Patterns

Mini 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.

Medium Labradoodles

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:

Mini/Medium Labradoodle Weight Prediction Formula:

Adult Weight = Weight at 18 weeks old x 2

Example: My Medium Labradoodle’s weight at 18 weeks is 25 pounds. Times 25 by 2 and I get 50 pounds as his predicted full-grown adult weight.

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.

Standard Labradoodle Size Chart

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

Standard Labradoodle Weight Prediction Formula:

Adult Weight = Weight at 23 weeks old x 2

Example: My Standard Labradoodle’s weight at 23 weeks is 35 pounds. Times 35 by 2 and I get 70 pounds as his predicted full-grown adult weight.


Here’s another formula that can help predict your Labradoodle’s adult size:

Growth = current weight / current age in weeks

Adult weight = Growth x 52 (number of weeks in one year)

Example: 12-week weight is 10 pounds. Divide the current weight by its age in weeks and multiply the result with 52: 10 / 12 = 0.83; 0,83 x 52= 43 pounds.


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.
