Radius Map
Draw a Radius on a Map From Any Address
A free map radius tool. Type an address, pick a drive-time, and we draw the polygon along real roads — not just a circle. For walking or cycling polygons from the same address, see the walking and cycling pages.

What is a drive-time radius?
The boundary of all locations reachable from a starting point within a given travel time, traced along the road network.
- A drive-time radius follows real roads - highways extend the boundary farther than local streets
- Walking and cycling radii from the same address are computed on dedicated pages and cover far less ground than driving for the same time budget
- The boundary updates whenever you change the starting address or time
- Pair this page with the walking and cycling pages to compare polygons across modes for the same point
Drive-time radius reflects how people actually travel. A straight-line distance circle overstates reachable area in cities and understates it on highways.
When to use a drive-time radius
Use a drive-time radius when...
- Defining a realistic service area for a field service team
- Measuring a retail store's 15-minute drive catchment area
- Planning last-mile delivery zones
- Analyzing patient travel time to a medical facility
- Any use case where roads, not straight-line distance, define reachability
A straight-line radius is fine when...
- You only care about proximity, not access
- You are doing rough air-mile calculations
- The area is rural and roads are sparse
- Regulatory definitions explicitly require mile-radius circles
How to create a radius map
Enter a center point
Type any address, ZIP code, city name, or place name. Autocomplete suggestions appear as you type.
Set your travel time
Enter a time from 1 to 60 minutes and choose driving, walking, or cycling. The radius is computed from real road network data.
Share or embed the map
Generate a shareable link to send the exact map to a colleague, or embed it on a website with a single iframe snippet.

Frequently asked questions
How do I draw a radius on a map?
Enter a center address, set the travel time in minutes, and click Calculate radius. The drive-time polygon appears on the map. Switch transport modes to compare driving, walking, and cycling.
What is the difference between a radius map and a drive-time map?
A traditional radius map draws a straight-line circle of fixed distance. A drive-time map (what RadiusMapper draws) shows the area reachable by road within a given time. Use straight-line for proximity; use drive-time for realistic service areas.
Can I share the radius map?
Yes - every search produces a shareable link and an embed snippet. The link recipient sees the same map without needing an account.
How is the polygon calculated?
RadiusMapper uses the Mapbox isochrone API to compute the road-network boundary from your starting point. The result reflects typical travel times rather than live traffic.
Does this page support walking and cycling?
This page draws driving polygons. For walking and cycling polygons from the same address, use the dedicated walking and cycling pages.
What is the maximum travel time?
The radius supports up to 60 minutes of travel time per polygon.
