Frequently asked questions
- How do I measure the distance between two points?
- Switch to Distance mode, then set two points by clicking the map, searching for an address, or using your current location as the first point. The straight-line distance appears instantly above the map, in miles or kilometers.
- How do I draw a radius around a location?
- Switch to Radius mode, enter a distance such as 1 mile, 5 miles, or 10 km, then click the map or search for a center point. A circle of that radius is drawn instantly, and the map auto-fits to show the whole area.
- Can I measure distance from my current location?
- Yes. Allow location access and your position is automatically set as the starting point, then click or search for any destination to see how far away it is.
- Miles or kilometers?
- Toggle between mi and km at any time using the units buttons in the top bar; distance and radius values convert automatically.
- Is How Far Is That? free, and is my location data stored?
- Yes, it's completely free with no account required. Your location, if you share it, is used only in your browser to center the map, and is never sent to or stored on our servers. See the privacy policy for details.
