To know how big your schnauzer will be when it grows up is important for planning the space it will occupy, its bed, exercise needs, and more. In breeds with different sizes, many wonder how to tell if a puppy will truly be miniature or, on the contrary, will grow into a standard or giant specimen.

In order to calculate the future size of the schnauzer you must make 4 observations that we explain below.


  • 1st step: know the size of the parents, if both are the same size, the puppy will obviously be the same size; if one is, for example, medium and the other miniature, the puppy will have an intermediate size between the two parents.
  • 2nd step: observe the size of the puppy’s ears and legs, if it is going to be large, usually, from puppyhood, it will have somewhat longer ears and legs.
  • Step 3: Another way to calculate how big the schnauzer will be is to analyze its weight as a puppy. At 4 months, take the puppy’s weight and height and multiply it by 2. The result will be the approximate adult weight.
  • 4th step: knowing up to what age the schnauzer grows can also help us to know the size of the schnauzer, especially at the time of adoption. The miniature schnauzer grows up to 9 months, the medium schnauzer up to 12 months and the giant schnauzer up to 15 months. Think that the significant growth happens until 6 or 7 months, after that the growth rate is slower.

By observing these guidelines you can calculate the size that your schnauzer will have in the future in an approximate way. To get the exact weight right is improbable and at the same time unimportant, the important thing is that you can be clear about the type of schnauzer you are acquiring. So that you can compare the weights we leave you, below, the table of official weights and heights for the 3 types of schnauzer.
