Labradoodle Weight Calculator

A Labradoodle is a crossbreed of a Labrador Retriever and a Poodle. Because the Poodle comes in three sizes, Labradoodles do too, and the single biggest factor in how big your dog gets is which size of Poodle was used as a parent.

There are three broad size groups: Miniature (15–25 lbs), Medium (30–45 lbs), and Standard (50–65 lbs). The calculator above defaults to a Standard Labradoodle, the most commonly searched size. Use the overview table below to find the group that matches your dog.

A full grown Standard Labradoodle weighs 50–65 lbs and stands 21–24 inches at the shoulder. Males generally finish at the heavier end (around 55–65 lbs) and females at the lighter end (around 45–60 lbs). Most Standards reach their full height by 12 months but continue to broaden through the chest and fill out with muscle until 18 months to 2 years of age.

Medium Labradoodles settle at 30–45 lbs and 17–20 inches, while Miniatures finish at 15–25 lbs and 14–16 inches. If your adult dog sits well outside the range for its size group, weigh it, feel its body condition, and speak to your vet. A Labradoodle that looks "big" is often simply carrying extra weight rather than being a larger size variety.

A full grown Mini Labradoodle weighs 15–25 lbs (roughly 7–11 kg) and stands 14–16 inches tall. Minis are produced by crossing a Labrador with a Toy or Miniature Poodle, which is why they come in noticeably smaller than the Standard. Within the Mini group there is still a fair spread: a dog from a Toy Poodle line can finish closer to 15 lbs, while one from a larger Miniature Poodle can reach the mid-20s.

Mini Labradoodles mature faster than Standards. Most reach close to their adult weight by around 12 months, with only minor filling out afterward. Because the difference between a lean and an overweight Mini can be just a few pounds, portion control matters even more at this size. A single extra pound on an 18 lb dog is a much larger proportion of body weight than it is on a Standard.

The interactive calculator at the top of this page shows a full month-by-month growth chart for a Standard Labradoodle, split by sex. Enter your dog's details to see where it sits against the healthy range for its age. Mini and Medium Labradoodles follow the same growth curve shape but at lower weights, so expect a Mini to reach roughly the same percentage of its adult weight at each age.

As a rule of thumb across all sizes, a Labradoodle reaches about half its adult weight by 4–5 months, around 75% by 6–7 months, and close to its final weight by its first birthday, with Standards adding a little more into their second year.

How long a Labradoodle takes to finish growing depends on its size. Smaller dogs mature earlier:

• Miniature Labradoodle: essentially fully grown by around 12 months.
• Medium Labradoodle: full adult size by 12–15 months.
• Standard Labradoodle: full height by about 12 months, but keeps filling out with muscle and chest depth until 18 months to 2 years.

A Labradoodle that still looks lanky and "leggy" at a year old is usually a Standard that has hit its adult height but has not yet developed its adult build. Keep feeding to body condition through this stage rather than free-feeding, as growth-stage weight gain is easy to add and hard to remove.

Generation labels tell you how the dog was bred, and they strongly affect coat type and how predictable the size will be.

• F1: a first-generation cross of a purebred Labrador and a purebred Poodle. Coats range from straight to wavy, shedding varies, and size within a litter is the least predictable.
• F1b: an F1 Labradoodle bred back to a Poodle, so about 75% Poodle. Coats are usually curlier and lower-shedding, which suits allergy-sensitive homes, and dogs often run slightly smaller.
• Australian Labradoodle: a multi-generation line bred to a standard, sometimes with other breeds such as Cocker Spaniel in its background. Size and coat are the most consistent of all.

If a predictable adult size matters to you, a later-generation or Australian Labradoodle from a breeder who publishes adult weights is a safer bet than an F1.

Feed your Labradoodle according to its adult size and activity level, and always measure portions rather than eyeballing them. As a starting point for a quality dry food, split across two meals a day:

• Miniature (15–25 lbs): about 1 to 1.5 cups per day.
• Medium (30–45 lbs): about 1.5 to 2.5 cups per day.
• Standard (50–65 lbs): about 2.5 to 3.5 cups per day.

These are guidelines only, so adjust up or down based on body condition, not the number on the scale. Labradoodles inherit the Labrador's love of food, so treats should stay under 10% of daily calories. For a tailored daily calorie target, use our Dog Nutrition Calculator.

As a cross, Labradoodles can inherit health conditions from either parent breed. The most important to know about are:

• Hip and elbow dysplasia: joint malformations common to both parent breeds. Excess weight accelerates their progression, which is a key reason to keep your dog lean.
• Ear infections: the floppy, hairy ears trap moisture. Regular checking and drying after swimming or baths helps prevent recurring infections.
• Progressive retinal atrophy (PRA): an inherited eye disease leading to gradual vision loss. Responsible breeders test parents for it.
• Addison's disease: a hormonal disorder seen in Poodle lines, causing lethargy, vomiting, and weakness. It is manageable once diagnosed.
• Exercise-induced collapse: a genetic condition carried in some Labrador lines where intense exercise triggers weakness or collapse. Awareness and DNA testing of parents reduce the risk.

Buying from a breeder who health-tests both the Labrador and Poodle parents is the single best way to lower these risks.

Labradoodles are friendly, intelligent, and deeply people-focused, a blend of the Labrador's easygoing warmth and the Poodle's cleverness. They are typically excellent with children and other pets, and they thrive on being part of family life. The flip side is that they dislike being left alone for long stretches and can develop separation anxiety or destructive habits when bored.

Exercise needs scale with size. A Miniature is usually satisfied with 30–45 minutes of activity a day, while Medium and Standard Labradoodles need 60–90 minutes of walks, play, and training. Their intelligence means mental work such as puzzle feeders, scent games, and obedience matters as much as physical exercise. A well-exercised Labradoodle is far easier to keep at a healthy weight and far calmer in the home.
