How do I draw a 10 mile radius circle on a map?
The circle opens at 10 miles around New York City, with its area in square miles and its edge in miles and kilometers. Click the map to move the center, or type coordinates; the circle is redrawn at once.
The circle starts at 10 miles around New York City. Click the map to move its center, or type coordinates in the box and press Set center. The circle is redrawn at once, and the panel shows its area and its edge.
To try another size, change the number or the unit in the panel. For a list of places, paste or drop a CSV file with one place per row: every row gets its own 10 mile circle, up to 200 rows. Addresses are not looked up, so each row needs latitude and longitude.
How many kilometers and square miles is a 10 mile radius?
A mile is a fixed length. NIST defines the international mile with an exact factor in meters (NIST Guide to the SI, Appendix B.8), so 10 miles converts to kilometers without rounding.
Worked example. 10 miles is 16.09344 km. A circle of that radius around New York City (40.71, -74.01) covers 314.16 mi², which is 813.66 km², and its edge is 62.832 mi long.
The area and the edge are measured on the WGS 84 ellipsoid, the model behind GPS, so they describe the ground and not the flat map. The panel also gives the radius in meters, kilometers and nautical miles.
Is 10 miles the distance you drive?
No. A radius is a straight line over the Earth’s surface from the center. A road from the center to the edge is never shorter than that line, and it is usually longer, because roads follow streets, rivers, bays and hills.
Use the circle to see the area a straight line reaches. To check one place against it, measure between two points with the distance measurer, which gives the straight-line distance. The tool draws circles; it does not count or list the places inside them.
Where is a 10 mile circle useful?
A service area. A business that serves customers within 10 miles can draw that area on the map before it makes the promise.
A search around one spot. Set the center where the search starts, and the circle shows the ground to cover.
A set of sites. With a CSV list, a network of branches or stores gets one 10 mile circle each, all with the same radius, so the places where the circles overlap are visible on one map.
Questions about radius circles
How many kilometers is 10 miles?
Exactly 16.09344 km. NIST defines the international mile with an exact factor in meters; the source is listed at the foot of this page.
What area does a 10 mile radius cover?
Around New York City, about 314.16 mi² (813.66 km²), measured on the ellipsoid. Another center gives a slightly different area, because the Earth’s surface is curved and not the same everywhere.
Can I draw a 10 mile circle around an address?
Not by typing the address. The tool does not look up addresses, because that means sending your text to a geocoding service. Enter the coordinates instead; most map apps show them when you press and hold or right-click a spot.
Does a 10 mile circle follow the roads?
No. It is a straight line over the Earth’s surface from the center. A road to the edge is at least as long as that line, and usually longer.
Can I draw 10 mile circles around many places at once?
Yes. Paste or drop a CSV file with one place per row, latitude and longitude with a name first if you like. Up to 200 rows are drawn, each with a 10 mile circle, and changing the radius redraws all of them. The list is not uploaded or saved.
Does the tool tell me which places are inside the circle?
No. It draws the circles on the map, but it does not count or list the places inside them. Compare the map with your own list.
Can I share the circle?
Yes. The link holds the center and the radius, so whoever opens it sees the same circle. A list of places is not in the link.
Which units can I use for the radius?
Kilometers, miles, nautical miles, meters, feet and yards, from the unit list in the panel.
