# Dog Size Calculator

By Łucja Zaborowska
Last updated: Oct 30, 2020

The dog size calculator works as a puppy size predictor - it allows you to compute how big your dog will be once it's fully grown-up. 🐶

Have you just adopted a stray puppy? Maybe you got a dog of a mixed-breed? Are you still wondering How big will my puppy get? Search no more - our puppy height and weight calculator is here to help.

Follow the article below for the details of the canine development and growth, dog growth calculator basics, breeds descriptions, and formulas used in our puppy size estimator. 🐕

## How much will my dog weight?

Our how big will my puppy get calculator uses the following equation:

`Adult weight = (Puppy weight / Puppy age in weeks) * 52`

Why 52?

52 is the number of weeks in a year. That's how we program the dog size predictor to give us your puppy's weight when he is exactly 1 year old.

We used this value in our puppy calculator because, on average, dogs mature into adults within 12 months. This value ranges from 8 months for smaller breeds to around 16 months for larger breeds.

According to your puppy weight calculator's results, we can place your dog into one of 5 major breed size groups:

 Toy dog < 12 lb / < 5.4 kg Small dog 12 - 22 lb / 5.4 - 10 kg Medium dog 22 - 57 lb / 10 - 25.9 kg Large dog 57 - 99 lb / 25.9 - 44.9 kg Giant dog >99 lb / >44.9 kg

 💡 Small dogs tend to live longer. For every increase of 4.4 pounds (2 kg) of body weight, a dog's lifespan decreases by 1 month. This way, the dog weight predictor serves as a tool for estimating your dog's longevity.

 💡 The tallest dog ever measured was a Great Dane of the name Zeus. Zeus had unbelievable 44 in (111.8 cm) of height! (from paw to shoulder)

## How to use the dog size calculator?

Our puppy growth calculator just couldn't get any simpler! Prepare your dog's weight in a weight unit of your choice and actual age in weeks or days.

The dog weight estimator will process these details of your puppy to its adult weight. Your results will also be displayed as a range, since there are many factors which may influence your dog's growth and final size.
