Map Radius Calculator – Draw Radius Circles on a Map
A Map Radius Calculator is a tool that allows you to draw a circle around any location on a map and measure the distance from the center point to the edge of the circle. It is useful for visualizing coverage areas, delivery zones, travel distances, service regions, emergency response areas, and property boundaries.
Whether you are a business owner planning delivery routes, a real estate professional analyzing neighborhoods, or simply trying to find locations within a certain distance, a map radius tool provides a quick and accurate solution.
What Is a Map Radius?
A map radius is the distance from a central point to the outer edge of a circle drawn on a map. The radius can be measured in kilometers, miles, meters, or feet.
- A 5 km radius shows all locations within 5 kilometers of the selected point.
- A 10-mile radius highlights all places located within 10 miles.
- A 50 km radius can be used to visualize a service coverage area.
How to Use the Map Radius Calculator
- Search for a location or use your current location.
- Click on the map to create a circle.
- Enter the desired radius distance.
- Adjust the circle color if needed.
- View the radius, area, and circumference instantly.
- Download the map image for reports or sharing.
Radius Area Formula
Where:
- A = Area
- r = Radius
- π ≈ 3.14159
Example
If the radius is 10 km:
Area = 314.16 km²
This means a circle with a radius of 10 kilometers covers approximately 314 square kilometers.
Circumference Formula
Example
For a radius of 10 km:
Circumference = 62.83 km
The circle boundary is approximately 62.83 kilometers long.
Practical Examples
Food Delivery Service
A restaurant wants to deliver food within a 5 km radius.
Area Covered:
A = π × 5² = 78.54 km²
Emergency Services
An ambulance station wants to analyze areas reachable within 15 km.
Area Covered:
A = π × 15² = 706.86 km²
