Labrador Retriever Height and Weight Chart – Size Guide by Age (Male vs Female)

I got my first Lab when I was twelve. She was a yellow female named Biscuit, and by six months old, she outweighed me.

That was my first real lesson in labrador weight – these dogs grow fast, and if you’re not paying attention, they’ll blow past every size estimate you had in your head.

Whether you just brought home a Lab puppy or you’re wondering if your adult dog is the right size, this labrador height and weight chart breaks down what to expect at every age.

I’ve included measurements in kg, pounds, cm, and inches because half the internet only gives you one unit and expects you to do math.

Labs are consistently one of the most popular family dogs in the world, and it’s not hard to see why. 

They’re trainable, patient with kids, and rarely aggressive. If you want to see how they compare to other popular breeds, check out the dog size chart by breed. But right now, let’s talk specifically about the Labrador Retriever.

Quick Facts About Labrador Retriever Size

The labrador retriever size falls in the medium-to-large category. They’ve got a solid, muscular build with a thick tail and a short, water-resistant coat. Males are noticeably bigger than females in both height and weight. 

A full-grown male Labrador stands about 22–24 inches (56–61 cm) at the shoulder and weighs between 29–36 kg (65–80 lbs). Females are slightly smaller at 21–23 inches (54–58 cm) and 25–32 kg (55–70 lbs).

Labs can look a bit stocky compared to other retrievers because they tend to carry more chest width and have shorter legs relative to their body. 

This means they sometimes take longer to fill out – most reach their adult labrador height by around 9–12 months but keep gaining muscle and weight until 18 months or even two years.

Female Labrador Height and Weight Chart

The female labrador weight tends to be about 5–10 kg lighter than males at full maturity. They’re also an inch or two shorter on average.

Here’s a breakdown of the typical labrador weight chart by age for females, with measurements in both metric and imperial:

AgeHeight (inches)HeightWeightWeight
3 Months10 – 14″25 – 35 cm10 – 14 kg22 – 31 lbs
6 Months14 – 17″35 – 43 cm16 – 20 kg35 – 44 lbs
9 Months17 – 20″43 – 51 cm19 – 24 kg42 – 53 lbs
12 Months20 – 22″51 – 56 cm22 – 27 kg49 – 60 lbs
18 Months21 – 23″53 – 58 cm24 – 29 kg53 – 64 lbs
2 Years21.5 – 23″54 – 58 cm25 – 30 kg55 – 66 lbs
3+ Years21.5 – 23″54 – 58 cm25 – 32 kg55 – 70 lbs

By about 12 months, most female Labs have reached their full labrador height in cm and inches.

After that, the changes are mainly in body composition – filling out the chest, gaining muscle, and settling into their adult frame.

If your female Lab seems lean at one year, that’s normal. She’ll likely fill out over the next 6–12 months.

Male Labrador Height and Weight Chart

Males are the bigger of the two, and the difference is pretty obvious once they’re past puppyhood.

The labrador retriever weight for males typically tops out between 29–36 kg (65–80 lbs), though some large-boned Labs can push into the mid-80s without being overweight.

Here’s the full labrador weight chart kg and lbs breakdown for males:

AgeHeight (inches)Height (cm)Weight (kg)Weight (lbs)
3 Months11 – 15″28 – 38 cm11 – 15 kg24 – 33 lbs
6 Months15 – 18″38 – 46 cm18 – 24 kg40 – 53 lbs
9 Months19 – 22″48 – 56 cm23 – 29 kg51 – 64 lbs
12 Months21 – 23″53 – 58 cm26 – 32 kg57 – 71 lbs
18 Months22 – 24″56 – 61 cm28 – 34 kg62 – 75 lbs
2 Years22 – 24.5″56 – 62 cm29 – 35 kg64 – 77 lbs
3+ Years22 – 24.5″56 – 62 cm29 – 36 kg65 – 80 lbs

One thing I’ve noticed with male Labs specifically: they can look gangly and thin around 8–10 months even when they’re eating well.

Don’t panic. That’s just the awkward teenager phase. They gain height first, and the bulk comes later.

If you want to track your puppy’s development week by week during that first year, the Labrador puppy growth chart has a more detailed month-by-month breakdown.

How Much Do Labs Weigh? Average Weight in kg and lbs

This is probably the single most searched question about Labradors, and the answer depends on sex, age, build, and whether your Lab is an English (show) type or American (field) type.

English Labs tend to be stockier and heavier. American Labs are leaner and taller.

So how much does a labrador weigh on average? Here’s a quick summary:

CategoryWeight (kg)Weight (lbs)
Adult Male29 – 36 kg65 – 80 lbs
Adult Female25 – 32 kg55 – 70 lbs
English (Show) Lab30 – 40 kg66 – 88 lbs
American (Field) Lab27 – 34 kg60 – 75 lbs

If you’re wondering how heavy is a labrador in kg and whether yours falls in the healthy range, the best check is the rib test.

Run your hand along your dog’s ribcage – you should feel the ribs without pressing hard, but they shouldn’t be sticking out visually.

If you can’t feel them at all, your Lab might be carrying extra weight. Diet control matters a lot here. Check out the Labrador Retriever food chart for feeding guidelines by age and weight.

How Tall Is a Labrador? Height in Inches and cm

When people ask how tall is a labrador, they usually mean the shoulder height (also called withers height). That’s measured from the ground to the top of the shoulder blades while the dog is standing on a flat surface.

The average labrador retriever height at maturity is 22–24.5 inches (56–62 cm) for males and 21.5–23 inches (54–58 cm) for females.

Labs usually reach their adult height somewhere between 9 and 12 months, even though they keep filling out in muscle and weight after that.

The labrador height inches measurement might seem smaller than people expect because we’re measuring to the shoulder, not the head.

A Lab that stands 23 inches at the shoulder could easily reach your waist or hip depending on your own height. For context on how Labs compare to wild canines in terms of build, the wolf vs dog size chart is worth a look.

How Big Will My Labrador Get? Three Ways to Predict Adult Size

Check Their Age

If your Lab is under 12 months, they’re almost certainly still growing. Most labrador retriever size and weight reaches roughly 90% of the adult range by the one-year mark.

After that, growth slows considerably – you’re mostly looking at weight gain and muscle development rather than height increase. Labs with larger frames may keep filling out until 18–24 months.

Look at Their Paws

This one is the oldest trick in the book, but it actually works. If your Lab puppy’s paws look comically large compared to their legs, they’ve got more growing to do.

Puppies with oversized paws tend to grow into bigger adults. Once the paws look proportional to the body, the major growth spurts are probably done.

Ask About the Parents

Genetics is the biggest predictor of final labrador size. If both parents are on the smaller end, your puppy likely will be too. And if both parents are 80+ pound dogs with broad chests, prepare accordingly.

The breed variety matters as well – English Labs are generally heavier and stockier, while American Labs are taller and leaner. No amount of food will turn a genetically small Lab into a giant one.

When Do Labradors Stop Growing?

There’s no single date you can circle on the calendar. Most Labs reach their adult lab height between 9 and 12 months. But they don’t stop changing after that.

Between their first and second birthdays, Labs continue to gain lab weight, adding muscle mass and chest width even though they’re not getting taller.

Mentally, a well-trained Lab should be past the worst of the puppy chaos by their first birthday. Physically, they settle into their adult body closer to 18–24 months.

Large-boned males sometimes take even longer. If your two-year-old Lab still seems lean, give it time – they may just be late bloomers.

During this growth period, feeding the right amount is important. Overfeeding a young Lab can cause joints to develop improperly, while underfeeding can stunt their growth.

The general dog food chart by breed, weight, and age is a good starting point for figuring out portions.

English Lab vs American Lab: Does Type Affect Size?

Yes, and the difference is bigger than most people realize. English Labs (also called show or bench Labs) were bred for conformation showing.

They have blockier heads, thicker necks, and heavier builds. American Labs (field Labs) were bred for hunting and retrieving – they’re leaner, longer-legged, and more athletic-looking.

TraitEnglish (Show) LabAmerican (Field) Lab
BuildStocky, broadLean, athletic
Weight Range30 – 40 kg / 66 – 88 lbs27 – 34 kg / 60 – 75 lbs
Height Range21 – 23″ / 53 – 58 cm22 – 25″ / 56 – 63 cm
Head ShapeBlock-shaped, widerNarrower, more refined
Energy LevelModerateHigh

This means if someone asks “how much do labs weigh?” and you answer “65–80 pounds,” that’s technically correct for males but doesn’t tell the whole story.

An English Lab male could weigh 90 pounds and be perfectly healthy. An American Lab at that weight might be overweight. Context matters.

Labrador Puppy Weight Chart in kg (Birth to 12 Months)

For owners tracking their puppy’s growth week by week, here’s a condensed labrador puppy weight chart kg covering the first year.

These are averages – your pup might be slightly above or below, and that’s fine as long as growth is steady.

AgeMale Avg Weight (kg)Female Avg Weight (kg)
Birth0.4 – 0.5 kg0.3 – 0.5 kg
1 Month1.5 – 2.5 kg1.2 – 2.2 kg
2 Months5 – 7 kg4 – 6 kg
3 Months11 – 15 kg10 – 14 kg
4 Months14 – 19 kg12 – 17 kg
5 Months17 – 22 kg14 – 19 kg
6 Months18 – 24 kg16 – 20 kg
8 Months22 – 28 kg18 – 24 kg
10 Months25 – 31 kg20 – 27 kg
12 Months26 – 34 kg22 – 29 kg

As a rough rule, Lab puppies gain about 1 kg (2 lbs) per week until around six months, then the pace slows to about 0.5–0.7 kg per week.

If your puppy is gaining weight much faster than this, it’s worth talking to your vet about adjusting food portions. For a detailed feeding plan during the puppy stage, see the Labrador puppy growth chart.

Dangers of Too-Fast or Stunted Growth

Not all growth deviations are a problem, but some are worth watching for:

Growing too fast is common in Labs because they love food and their owners love feeding them.

But rapid weight gain puts stress on developing bones and joints, and Lab puppies are already prone to hip and elbow dysplasia.

Overfeeding a puppy doesn’t make them bigger – it makes them heavier, and that’s not the same thing. Excess weight during puppyhood can cause lasting structural damage.

Growing too slowly could signal nutritional deficiency, intestinal parasites, or an underlying health condition.

If your Lab seems significantly behind the labrador weight by age chart and also seems lethargic or has a dull coat, a vet visit is a good idea.

Genetics also plays a role here. Smaller parents tend to produce smaller puppies, and that’s perfectly normal.

The goal isn’t to hit a specific number on a chart – it’s to see steady, proportional growth without sudden spikes or drops.

What Labrador Size Means for Everyday Life

Knowing your Lab’s size isn’t just about tracking growth – it affects a bunch of practical decisions:

Crate sizing: A full-grown Lab typically needs a 42-inch crate. Getting the wrong size means your dog is either cramped or has too much room (which can interfere with housetraining).

The dog crate size chart by breed can help you match the right crate to your Lab’s measurements.

Bed sizing: Labs need large or XL beds depending on how they sleep. Curlers can get away with slightly smaller beds, but stretchers need something around 100 x 80 cm or bigger. See the dog bed size chart by breed for specifics.

Dog house: If your Lab spends time outdoors, the dog house needs to be proportional – big enough to turn around in but not so large that it can’t retain body heat.

The dog house size chart covers dimensions for Labs and other large breeds.

Clothing: If you live somewhere cold enough to need a dog sweater or jacket, a Lab typically falls in the XL range

 Chest girth is the key measurement. The dog sweater size chart lists Labs specifically along with other breeds.

How Does Size Affect a Labrador’s Lifespan?

Larger dogs, as a general rule, live shorter lives than smaller ones. Labs average about 10–12 years, which is typical for breeds in their weight range.

Keeping your Lab at a healthy weight is one of the single best things you can do for their longevity. A 2018 study found that Labs maintained at a lean body condition lived nearly two years longer than their overweight counterparts.

For a broader look at how breed and size affect how long dogs live, see the dog life expectancy chart by breed. It puts Labs in context alongside other popular breeds.

Labrador Retrievers as Working Dogs

The Labrador’s size – big enough to handle physical tasks but not so massive that they lack agility – makes them one of the most versatile working breeds in the world.

They’re used as guide dogs, search-and-rescue dogs, detection dogs, and therapy dogs. Their temperament helps, but their medium-large frame is a big part of why they’re chosen for these roles.

If you’re interested in how the Lab stacks up against other breeds that were built for jobs, the working dog breeds chart ranks them alongside German Shepherds, Belgian Malinois, and other common working dogs.
