Common uses for a circle on a map
A circle drawn around a fixed point is the simplest way to define a service area or coverage zone before it goes into whatever system actually enforces it -- a delivery app's zone editor, an ads platform's radius targeting, or a printed flyer's "we deliver within X miles" line. Three common shapes this takes:
- Delivery area -- a tight radius (often 3-7 miles) around a restaurant, shop or warehouse, where travel time matters more than raw distance.
- Service radius -- a wider radius (10-30 miles is common) around a home-service business base, like a contractor, cleaner or mobile mechanic.
- Commuting range -- a radius around a workplace or home used as a rough "how far is too far" filter, understanding that actual commute time depends on roads and traffic this straight-line radius doesn't model.
Worked examples
Computed with the same area = πr² formula used on every page of this site.
| A tight 5-mile delivery radius covers | 78.5 mi² |
| A 15-mile service radius covers | 706.9 mi² |
Note how tripling the radius (5 to 15 miles) covers about nine times the area, not three -- area scales with the square of the radius.
Frequently Asked Questions
What's the difference between this page and the homepage's Draw a Radius tool?
Nothing under the hood -- they run the exact same engine, up to five circles, address search, and a shareable link. This page exists because "circle on a map" and "draw a radius" are two different ways people search for the same task, so both land on the same tool with the framing that matches what brought them here.
What's a realistic radius for a delivery or service area?
It depends entirely on what's being delivered and how. A same-day local delivery service (food, flowers, a small local courier) commonly draws a 3-7 mile circle around a single location; a regional service area for something like appliance installation or a multi-location business might use 15-30 miles per location. Draw a candidate radius above and check the area figure -- it's often larger than it looks on a map.
Can I use this to define a service-area boundary for my business listing or ads?
You can use it to visualize and communicate a radius, and the shareable link makes it easy to hand off to a teammate or a printer. It isn't a substitute for whatever radius-targeting tool your specific ad platform, delivery software or business listing provider uses internally -- treat this as a planning and communication aid, not a live integration.
How accurate is the circle at the edge, over long distances?
The circle is a true geodesic circle (every edge point genuinely that far from the centre along the Earth's surface), so it stays accurate at any radius you'd realistically draw for a service area -- a few hundred miles at most. See the homepage's explainer for why the circle can look stretched into an oval at high latitudes even though the underlying radius is exact.
Can I compare a delivery radius against a commuting range on the same map?
Yes -- add a second circle at the same or a different centre, give it its own label (like "Delivery" and "Commute"), and both draw simultaneously in different colours so you can see where they overlap or diverge.
Every distance, area and radius on this site is a geometric estimate from the coordinates you provide, not a survey-grade measurement -- and this tool does not calculate driving routes or travel time. See the Terms.
