How big will my dog be?
If you've adopted a purebred and have a good idea of size averages, or have adopted a mystery pup who could end up weighing 20 or 80 pounds a year, you've probably wondered, "How big will my dog be?" 🇧 🇷
That's why we've built this simple formula to give you a rough estimate of how much your dog will grow. It's not perfect, but this dog weight calculator gives you a reasonably good indicator of how much weight you'll carry on adventures once your pup is fully grown into an adult dog.
Follow our dog size chart broken down by breed and use our formula to find out how big your furry friend will be.
How big will my dog be?
It's the age old question that every new homeowner wants to know. There's the old notion that the legs will tell you, but they're not exactly a measurable indicator that you can use with precision.
These days, the best way to find out your dog's size is with a puppy height and weight calculator. By taking your pup's current weight, dividing by the age, and multiplying by 52, you can get a better idea of how big your pup will be when he reaches his first year.
When do puppies stop growing?
For most pups, they stop growing between 1 and 2 years of age. On average, dogs take 12 months to mature, but the larger the breed, the longer the process, and giant breeds tend to take a full two years to reach their full height and weight.
As our puppy weight calculator uses a one year time period, it is possible that your dog is slightly larger than the estimate. If desired, adjust the number 52 (52 weeks for a 1-year measurement) to a larger number. Be careful though, as growth starts to slow after the 1 year mark, so the measurement will become less and less accurate with the adjustments you make.

Ultimate Puppy Weight Calculator - Determine Your Dog's Adult Size
Here's the simple formula to estimate your dog's individual size at the one-year mark, regardless of breed.
Puppy adult weight = (Puppy weight in pounds ÷ Puppy age in weeks) x 52
Just like in math class, follow BEDMAS - Brackets Matter! Be sure to complete the division first, then multiply that total by 52 to calculate the results correctly.
Let's take a look at an example of a quick weight calculation.
If your average size puppy weighs 12 pounds at 16 weeks of age, you:
12 pounds ÷ 16 weeks = 0.75
0.75 x 52 = 39 pounds not adult weight.
