About the bounding box tool

A bounding box (bbox) is the smallest rectangle that contains an area, expressed as minimum and maximum longitude and latitude. Bboxes are everywhere in GIS โ€” querying APIs, the Overpass/OpenStreetMap API, clipping rasters, and defining map extents. This tool gives you the same box in every common format at once.

How to use it

  1. Click two opposite corners on the map โ€” or type the four bounds.
  2. Copy whichever output format your tool expects.

Frequently asked questions

What order are the numbers?

The GeoJSON / standard order is West, South, East, North (minLon, minLat, maxLon, maxLat). Overpass and some OSM tools expect South, West, North, East โ€” both are provided.

What's the WKT output for?

WKT (Well-Known Text) POLYGON is accepted by PostGIS, QGIS and many spatial databases.
