Is there a way to get the extent (bbox) of a vector layer in QGIS?

I see that I can update the extent, but I am looking for the actually coordinates of the extent.

The layer extents are available in the Layer Properties | Metadata section.

To get a bounding box in QGIS as a new vector layer:
Menu -> Vector -> Research Tools -> Polygon from layer extent enter image description here

  • I don't really want to create a new file. I am only interested in the four coordinates. – ustroetz Feb 3 '14 at 17:08
  • You could just use extract the nodes of the newly created polgygon and use the Export/Add geometry columns tool to get the corner coordinates. Put everything into a Processing model and it runs in no time...? – Curlew Feb 3 '14 at 17:15

PostGIS has the ST_extent function which generates boundingbox for you. So my approach would be to export the layer to a database. if you want id,name, geom, boundingbox just do

select id,name,geom,ST_extent(geom) from your_table group by id
