Map Radius Tool

Draw circles on a map to visualize distances from any address or from your current location. Set your radius in miles or kilometers, drag to resize, and see measurements in real time. List the ZIP codes inside any circle and share your map with a link.

How to Use the Map Radius Tool

  1. Search for a location using the address bar, tap Use My Location to start from where you are, or click any point directly on the map to place a circle.
  2. Set your radius by entering a distance and choosing your unit: miles, kilometers, or meters.
  3. Resize by dragging the edge handle on the circle, or type an exact value into the radius input. The measurement updates in real time.
  4. Move or add more circles by dragging the center point to reposition, or click elsewhere on the map to place additional circles.
  5. Name and share your circles by typing a name on a circle's card, then pressing Copy share link.

Find ZIP Codes Within a Radius

Once your circle is on the map, press List ZIP codes to see every ZIP code area inside it. Each one is marked as fully or partly inside, so you can decide whether a ZIP code on the edge counts. Copy the list, download it as a CSV, or open it in the ZIP code map maker to get a shaded ZIP code radius map you can download.

The list checks ZIP code boundaries against the circle, not a single point per ZIP code, which is what makes the partly inside answer possible. The boundaries are 2020 Census ZIP Code Tabulation Areas, simplified for display. They approximate the area a ZIP code serves but are not official USPS delivery boundaries.

What Is a Radius Map?

A radius map shows a circular area around a central point at a fixed distance. Unlike driving directions that follow roads, a radius circle represents straight-line distance in all directions, sometimes called “as the crow flies.” This makes radius maps useful for quickly understanding geographic reach, whether you need to visualize a delivery zone, check what falls within a mile of your location, or compare coverage areas across multiple points.

A circle answers “how far,” which is not always the question. When the area you care about is defined by ZIP code rather than by distance, a shaded map of those ZIP areas is the clearer picture, and the two often go together: draw the radius here to find the reach, then use the ZIP code map maker to fill in the specific codes you cover. It matters which one you use for a boundary question, because a ZIP code is an area rather than the single point most tools reduce it to.

From a Radius to a Territory Map

Once a circle shows you the reach, the next step is often a map of the areas inside it: the counties a store serves, the ZIP codes a delivery route covers, or the states a regional office is responsible for. Those boundaries rarely follow a circle, so they are better shown as shaded regions. Browse ZIP code maps for every US state, use the US counties map for county-level coverage, or color states and counties yourself with the US map maker.

Use Cases

Delivery & Service Zones

Draw a radius around your warehouse, store, or office to visualize your service area, then shade the ZIP codes you serve with the ZIP code map maker.

Real Estate

Find properties within a specific distance of a school, office, or transit stop. Compare neighborhoods with multiple circles.

Event Planning

Check how accessible a venue is for attendees by visualizing distances from highways, airports, or population centers.

Sales Territory Planning

Visualize coverage areas for sales reps or regional offices. Use multiple circles to spot overlaps, then turn them into a sales territory map.

Education & Research

Analyze demographic data, study geographic distributions, or define study areas for environmental or social research.

Personal Use

Curious what's within 10 miles of your home? Draw a circle to explore nearby restaurants, parks, gyms, and more.

Frequently Asked Questions

Enter an address or click any point on the map, set your desired radius distance in miles, kilometers, or meters, and the circle will appear instantly. You can drag its edge to resize or drag the center to move it.

Set the radius to 50 and choose miles, then press "Use My Location" and allow location access when your browser asks. A 50-mile circle appears centered on where you are. The same works for any distance, from a few hundred feet to thousands of miles.

Yes. You can place as many circles as you need to compare coverage areas, find overlapping zones, or visualize multiple locations at once.

You can choose from metric (kilometers, meters), imperial (miles, feet, yards), geographic (nautical miles, leagues, furlongs), and even fun units like marathons, football fields, bananas, and Eiffel Towers. Switch between units at any time using the dropdown.

Yes. The radius measurement updates in real time as you drag the circle's edge, so you always know the exact distance.

Yes, the map radius tool is completely free to use, with no account or signup required.

Yes. The tool works on any modern browser, including mobile devices. Tap to place a circle and drag to resize it.

The tool uses geodesic calculations that account for the Earth's curvature, providing accurate distance measurements even over large distances.

A radius map shows a perfect circle of equal distance in all directions from a point. A drive-time map shows the actual area reachable within a certain time based on road networks. A radius map is simpler and faster to create, while a drive-time map accounts for real-world routes.

Draw your circle, then press "List ZIP codes" below the map. The tool lists every ZIP code area the circle touches, marks each one as fully or partly inside, and lets you copy the list or download it as a CSV. ZIP code listing works for circles up to 100 miles across the United States.

Boundaries. A ZIP code covers an area, so the tool checks the ZIP code shape against the circle rather than a single center point. That is why a ZIP code can be partly inside. The shapes are 2020 Census ZIP Code Tabulation Areas, which approximate USPS ZIP codes but are not official delivery boundaries.

Yes. Press "Color these ZIP codes on a map" in the ZIP code list and the codes open in the free ZIP code map maker, already colored. With several circles, each circle becomes its own color and legend entry.

Yes. Press "Copy share link" to copy a link to your circles. Anyone who opens the link sees the same circles with the same sizes, colors and names. Nothing is uploaded, because the circles are stored in the link itself.

Yes. Each circle gets a default color automatically, but you can change it using the color picker in the circle controls panel. This is especially useful when working with multiple circles.
