Measure area and distance on a map
Draw a polygon to read its area, or a line to read its length, directly on an interactive map. Geisro updates the measurement as you draw and can label every edge with its dimension. Free and browser-based.
How to measure on a map
- Open the map editor and sign in for free.
- To measure area, draw a polygon around the region - the enclosed area is shown as you draw.
- To measure distance, draw a line - the total length and segment lengths update live.
- Open the dimensions view to see each edge labelled with its length.
- Save the measured geometry to a layer in your project.
FAQ
Can I measure both area and distance?
Yes - polygons report their area and lines report their length, with per-edge dimensions available in the dimensions view.
Do I need to install anything?
No. Everything runs in your browser. Open the map editor and start measuring.
Is it free?
Yes - sign in with Google and measure on the map for free.
