How Big Do Pet Rats Get

Do you have your heart set on a rat for a pet but are wondering about how big they growers? Maybe you’re considering adopting an adult rat and are wondering if they’ll be too large for your home. Maybe you have your eye on a breeding pair of rats and want to make sure they’ll be a good size for your set-up. Whatever the reason if you’re wondering about how big pet rats get read on for all the info you need!

The first thing to keep in mind is that there is some variation in size between different rat breeds. However in general pet rats will fall into one of two size categories: Standard or Dwarf. Standard rats are as you might expect the larger of the two types. They typically weigh between 10-12 ounces and their bodies measure between 12-16 inches in length. Dwarf rats on the other hand are smaller all around. They typically weigh between 6-8 ounces and their bodies measure between 8-10 inches in length.

Of course even within these size categories there is some variation. For example Standard rats can range anywhere from 10-12 ounces with 12 ounces being on the larger end of the spectrum. And Dwarf rats can range anywhere from 6-8 ounces with 8 ounces being on the larger end of the Dwarf size spectrum. So if you’re looking for a particularly large or small rat be sure to ask your breeder or rescue organization about the size of the specific rats they have available.

In terms of height pet rats typically measure between 8-10 inches tall regardless of whether they are Standard or Dwarf. However like with weight there is some variation within this range. For example a Standard rat might measure 8 inches tall while a Dwarf rat might measure 10 inches tall. Again if you’re looking for a particularly tall or short rat be sure to ask your breeder or rescue organization about the height of the specific rats they have available.
