Radius Map: Draw a Distance Radius on a Map
Draw a radius circle around any address or map point and instantly see the distance covered and the area inside. Set the radius in kilometres, from a small neighbourhood ring to a wide regional catchment.
Or click anywhere on the map to drop the centre point.
What is a radius map?
A radius map draws a circle of a fixed distance around a central point. Everything inside the circle is within that straight-line distance of the centre, which makes it perfect for questions like which stores sit within 5 km, or which postcodes fall inside a 20 km delivery ring. This tool lets you set the radius, place the centre by address or by clicking the map, and reads out the exact area and circumference.
Radius vs drive time
A radius is a straight-line, as the crow flies measure. It is simple and fast, but it ignores roads: two points the same distance from the centre are treated equally even if one is a quick motorway hop and the other is across a river. When you need the real reachable area by car, on foot, or by bike, use the travel time map, which follows the actual network instead of a perfect circle.
How this tool works
Enter an address and we forward-geocode it to a coordinate with the MapAtlas Geocoding API, or click the map to set the centre directly. The tool then converts your radius into degrees of latitude and longitude at that latitude, places 128 points around the centre and joins them into a circle. For the 1 to 50 km radii on offer, every point lies within 1 percent of the chosen distance. It also shows the area inside the circle and its circumference. For programmatic radius and proximity queries at scale, the MapAtlas API exposes geocoding and spatial search through stable endpoints.
When you need this
Retail catchment sizing, franchise territory planning, real estate search radius, event and store proximity marketing, service area maps, and any brief that starts with within X kilometres of. A radius map turns a distance rule into a shape you can see and share.
