Puppy weight calculator helps you to estimate your puppy’s current weight and shows a prediction about weight when it is grown to an adult.

So if you have adopted a puppy and want to know its mass, then using this dog size calculator is your best choice to make.

## How Big Will My Puppy Get?

You can determine the size of your pet with the help of the following equation:

$$\text{Adult Weight} = \frac{\text{Puppy Weight}}{\text{Puppy Age In Weeks}}$$

According to the weight of the puppy measured at various intervals of time, the overall weight range of different dog types is listed in the following table below:

 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

It may seem a time consuming task to measure the weight of your pet manually. This is why we have designed this free puppy weight calculator so that it becomes no more tough for you to weigh your dog.
