Draw a distance circle around a chosen center
Search for an address or place, paste latitude and longitude, or use your current location as the center. Set the radius and the map draws a circle representing the same straight-line distance in every direction from that point.
Use radius maps for rough coverage questions
A distance circle can help compare service areas, delivery ranges, event catchments, field-work zones or how far a stated distance extends around a location. It is a geometric reference, not a promise that every point inside the circle can be reached by road within the same distance or time.
Area and circumference are geometric estimates
The page also reports approximate area and circumference from the chosen radius. These values describe the drawn circle and are useful for quick comparisons. They do not account for administrative boundaries, terrain, coastlines, restricted zones or the actual shape of a business service area.
Large radii need extra interpretation
Web maps project a curved Earth onto a flat screen, so very large circles can look different depending on latitude and zoom. The radius calculation represents ground distance from the center, while the visual map projection can distort shapes and scale.
Check the center point before using the circle
If the address search resolves to the wrong city, building or entrance, the entire radius will be centered incorrectly. Zoom in, verify the marker and use coordinates when you need a repeatable center point.
Radius is different from travel-time coverage
A 10-mile or 10-kilometer radius does not mean a vehicle can reach every point inside it within a fixed time. Travel-time analysis requires road speeds, network connectivity, barriers and current routing data.
