Radius Map

Draw a radius in miles or km around a point, town or ZIP Code. List every US city and ZIP area inside, nearest first, then copy it or download a CSV.

Example: 10 miles around the Space Needle in Seattle. Type your own point over it, or use your location.

Device location needs your permission. Your location stays in this tab until you choose an outside map or share it.

10 miles (16.1 km) from this point

Every calculated boundary point is this surface distance from the center. It is not a travel-time area. Wide circles and polar areas distort on a flat map; use the listed coordinates for their exact positions.

Direction	Boundary point
North	47.765232, -122.349300
East	47.620300, -122.134577
South	47.475768, -122.349300
West	47.620300, -122.564023

How to draw a radius, and what counts as inside it

The location finder connects a point to its city, county, ZIP area and time zone. Elevation accuracy explains terrain and device heights; IP versus GPS explains why location methods differ.

What Plant Hardiness Zone Am I In?Find the USDA 2023 plant hardiness classification listed for a US ZIP code. See the winter minimum temperature range and what a ZIP result cannot tell you.Bearing CalculatorCalculate initial, final and constant-course bearings between two coordinates. Compare the directions relative to true north.Horizon Distance CalculatorEnter eye height above a clear, level surface to estimate the geometric horizon. Compare line-of-sight and surface distances without atmospheric refraction.Antipode FinderFind the opposite point on Earth from a latitude and longitude. Copy its coordinates or open the point on a map.How Fast Am I Going?See the speed your phone reports in miles per hour and kilometers per hour, with the time and accuracy of each reading.Share My LocationChoose a location, check its accuracy, then copy coordinates or share a map link once. No live tracking or saved location history.Track My LocationStart and stop a live view of your own device position. See coordinates, accuracy, speed and heading when your device supplies them.Coordinate ConverterConvert between decimal degrees, DMS, DMM, UTM, MGRS, geohash and Plus Code, both ways. Paste a coordinate in any of them and copy the rest.Distance from My LocationCompare two coordinates and calculate their straight-line surface distance in miles and kilometers. This is not a road route.Midpoint CalculatorFind the geographic midpoint between two coordinates and open it on a map. A geographic midpoint is not a driving halfway point.Elevation ProfileChoose two US coordinates and request sampled USGS ground heights between them. See the climbs and drops in feet and meters.Topographic MapEnter US coordinates to view the USGS topographic map around that point. Inspect contour and terrain context, then open the official map.Time Zone ConverterConvert a date and local time between IANA time zones. Detect times skipped or repeated during daylight-saving clock changes.
