How to Draw a Radius on Google Maps (Free Alternative)
7 min read
Google Maps is the world's most popular mapping app, but it doesn't have a built-in tool for drawing radius circles. If you need to see "everything within 10 miles of this point," Google Maps can't do it natively — you need a third-party tool.
Free alternative: Use SimpleMapLab's Map Radius Tool to draw circles on an interactive map with instant area and perimeter calculations. No sign-up, no download.
Why Google Maps doesn't have a radius tool
Google Maps is designed for navigation — getting from point A to point B. Features like radius circles, area measurement, and isochrone mapping are GIS (Geographic Information System) functions that serve a different use case. Google offers these through the Google Maps Platform API, but not in the consumer-facing app.
How to draw a radius circle (step by step)
- Open the Map Radius Tool — it loads instantly in any browser, no account needed.
- Set your center point — search an address, click the map, or use GPS with "Detect My Location."
- Set the radius — use the slider (1–500 miles), type a custom value, or click a preset (5, 10, 25, 50, or 100 miles). Toggle between miles and kilometers.
- Read the results — the circle appears instantly, and the stats panel shows area, perimeter, and diameter.
What can you do with a radius circle?
- Real estate: See all neighborhoods within 30 miles of your workplace
- Delivery zones: Define how far your restaurant delivers
- Signal range: Visualize cell tower or Wi-Fi coverage
- Job search: Find jobs within commuting distance
- Emergency planning: Show evacuation zones around a facility
- Marketing: Define a local advertising radius
Beyond circles: what else can you do?
A radius circle shows straight-line distance, but real travel follows roads. For a more realistic view of what you can reach, try these tools:
- Drive Time Map — see how far you can actually drive in 15, 30, or 60 minutes (follows real roads, not a circle)
- Find ZIP Codes in Radius — list every ZIP code within your radius, with population data and CSV export
- Find Cities in Radius — find all cities and towns within a distance
- Population Within Radius — calculate the total population inside any circle
- Map Area Calculator — draw custom shapes (not just circles) and measure their area
- Distance Between Two Places — measure the exact distance between any two points
