I'm not sure how breed affects the range of a cat, but food source (if the cat is provided food by owners, or if the cat has to hunt food) is known to affect how far a cat may travel.
A study by in 2011 performed by the University of Illinois using radio collars determined:
The mean home range for pet cats in the study was less than two hectares (4.9 acres).
It's often thought (using studies that track cat movement though observations of people instead of radio collars) that gender and season affect the range of a cat, but they couldn't find a relationship in the radio collar study.
A surprising result of that study is that
Most of the cats in the study stayed within about 300 meters of human structures, said co-author Nohra Mateus-Pinilla, a wildlife veterinary epidemiologist at the Illinois Natural History Survey at Illinois.
“Even feral cats were always within range of a building,” she said. “That shows that even though they’re feral, they still have a level of dependency on us.”
So if you have no neighbours, this result may be more applicable to your situation than the previous "average housecat".
