Radius Map Tool

How to Draw a Radius on a Map

Drawing a radius on a map takes three steps:

1

Choose your center point

Type an address, city, or zip code in the search bar — or click “Use My Location” to center the radius on your current GPS position.

2

Set your distance

Enter the radius distance and select your unit (miles, km, meters, or feet). Use quick presets for common distances.

3

Adjust and share

Drag to reposition, resize by dragging the edge. Copy the shareable link so anyone can see your map.

What Can You Do With This Radius Map Tool?

This tool draws a circle on a map at a specific distance from any point. That circle represents every location within that straight-line distance from your center point — also known as an “as the crow flies” radius.

Here are some common ways people use it:

Check what's within a distance from you.

Enter your home address, set a 10-mile radius, and see exactly how far 10 miles extends in every direction. This helps with commute planning, understanding delivery zones, or answering “how far is 10 miles from me?” visually.

Compare multiple locations.

Add circles around two or more addresses to see where they overlap. Useful for finding a meeting point, comparing service areas, or choosing between apartments based on proximity to work.

Define a service or delivery area.

Businesses use radius maps to establish coverage zones. Draw a 25-mile radius around your office to define where you'll accept service calls, or set a 5 km radius for food delivery.

Visualize specific distances.

It's difficult to picture what “50 miles” actually looks like on a map. Drawing a radius makes it immediately clear — you can see which cities, highways, and landmarks fall within that distance.

Plan travel and relocation.

Moving to a new city? Draw a radius around your workplace to see which neighborhoods are within a comfortable commute distance. Pair this with our drive time map tool for more accurate travel-time estimates.

Radius Coverage: Area vs Distance

Radius area grows exponentially with distance. Doubling the radius quadruples the area covered. This chart shows how quickly coverage expands.

Area Covered by Radius (in square miles)

1 mile radius3.14 sq mi
5 mile radius78.5 sq mi
10 mile radius314 sq mi
25 mile radius1,963 sq mi
50 mile radius7,854 sq mi
100 mile radius31,416 sq mi

Formula: Area = π × radius². A 100-mile radius covers the same area as the state of South Carolina.

Common Starting Radii by Use Case

If you're not sure what radius to draw, these are rules of thumb people often start with for common tasks. They aren't industry standards — adjust to your actual location, traffic, and product before treating any of them as a real boundary.

Typical starting points

Food Delivery3-5 miles
Retail Store Catchment5-10 miles
Home Services (HVAC, Plumbing)15-25 miles
Healthcare (Hospital Service Area)25-50 miles
Regional Sales Territory50-100 miles

Radius Quick Reference

The table below shows common radius distances and what they typically cover. Use the presets in the tool above to draw any of these instantly.

RadiusApprox. AreaTypical CoverageCommon Uses
1 mile (1.6 km)3.1 sq miA neighborhoodWalking distance, small delivery zones
5 miles (8 km)78 sq miA city sectionCommute radius, restaurant delivery
10 miles (16 km)314 sq miA metro areaService area, daily commute
25 miles (40 km)1,963 sq miA regionRegional sales territory
50 miles (80 km)7,854 sq miMultiple citiesDay trip planning, logistics
100 miles (161 km)31,416 sq miA large regionFreight radius, weekend trips

Note: Area values assume a perfect circle. Actual reachable area depends on roads, terrain, and natural barriers. For real-world travel distances, use our drive time map instead.

How This Tool Works

Map With Radius uses Leaflet, an open-source mapping library, with map tiles from OpenStreetMap. Unlike tools that depend on Google Maps, this means:

  • No usage limits. Google Maps API charges per load after a free tier. Our tool has no API costs, so there are no restrictions on how many circles you draw or how often you use it.
  • No API key required. You don't need an account, API key, or any setup. Open the page and start drawing.
  • Fast loading. Leaflet is lightweight (~40KB) compared to the Google Maps JavaScript API (~200KB+). The map loads faster, especially on mobile.
  • Tool-side privacy. Map tiles come from OpenStreetMap, not Google Maps, so the map itself doesn't send your location or search queries to Google. (For analytics, ads, and EEA/UK consent, see our Privacy Policy.)

The radius circles are calculated using the Haversine formula, which accounts for the Earth's curvature. This means the circles are geographically accurate — a 50-mile radius really is 50 miles from the center point in every direction.

Address search is powered by Nominatim, OpenStreetMap's free geocoding service. It supports addresses, cities, zip/postal codes, landmarks, and coordinates.

Depending on what you need, one of our other tools might be a better fit:

  • Drive Time Map — Shows how far you can actually drive (or walk, or cycle) in a given time. Uses real road data instead of straight-line distance.
  • Zip Code Radius — Enter a zip code and distance to find all zip codes within that radius. Returns a list you can export.
  • KM Radius Map — Same tool, metric-first. Defaults to kilometers for users outside the US and UK.
  • Walking Radius Map — See how far you can walk or cycle in a set time. Shows realistic walking/biking areas based on actual roads and paths.
  • Distance Calculator — Measure the straight-line or driving distance between any two points on a map.

Frequently Asked Questions

Can I draw a radius on Google Maps?
Google Maps does not have a built-in radius tool. You cannot draw a circle directly in Google Maps or Google My Maps without workarounds involving KML files. Use our tool instead — it works with OpenStreetMap and lets you draw radius circles instantly. Read our full guide on radius on Google Maps →
How do I find what's within a 10-mile radius of my location?
Click “Use My Location” in the tool above, then set the radius to 10 miles. The circle shows everything within 10 miles of your current position. You can zoom in to see specific streets, landmarks, and neighborhoods within the radius.
Is this tool really free?
Yes. Map With Radius is completely free with no limits. There's no account to create, no premium tier, and no usage cap. The tool runs on open-source technology (Leaflet + OpenStreetMap) which has no per-use costs.
What's the difference between a radius and drive time?
A radius shows straight-line distance from a point — “as the crow flies.” Drive time shows how far you can actually travel by road in a given time. A 10-mile radius is a perfect circle, but a 10-minute drive is an irregular shape that follows roads. We offer both: this tool for radius circles, and our drive time map for travel-time areas.
Can I share my radius map with someone?
Yes. Click “Copy Link” to get a URL that contains your exact map settings — center point, radius distance, and circle positions. Anyone who opens the link sees your map exactly as you set it up.
How accurate is the radius?
The radius uses the Haversine formula, which accounts for the Earth's curvature. It is highly accurate for typical radius sizes; the spherical-Earth approximation introduces sub-percent error only at continental distances. The circles represent straight-line distance, not road distance.
Can I add multiple radius circles?
Yes. Click “Add Another Circle” to place additional circles on the same map. Each circle can have its own center point, radius distance, and color. This is useful for comparing coverage areas or finding overlap between locations.
Does this work on my phone?
Yes. The tool is fully responsive and works on all modern browsers, including Safari on iOS and Chrome on Android. Touch and drag to pan the map, pinch to zoom, and tap to place circles.
Can I export the map?
You can export in three ways: (1) Copy a shareable URL link, (2) Download a PNG screenshot of your current map view, (3) Export circle data as a KML file that you can open in Google Earth or other GIS software.
