Using the population of the city where you wish to open a studio, determine if your location is far enough away from an existing studio. Use this as a general guideline but know that the distance is subject to be smaller or bigger based on the population density of the area.
0-150,000 = 12 km/7.45 miles
150,000-300,000 = 10 km/6.21 miles
300,000-500,000 = 8 km/4.97 miles
500,000-700,000 = 6 km/3.72 miles
700,000- 4 million = 5 km/3.1 m
Note: the distances listed above are not 'driving distances' they are 'as the crow flies'. You can figure if your location interfere's with another studio's territory by plugging the addresses in here.
