Returns the length of a geometry.

Usage¶

double ST_Length(geom: geometry)

Arguments¶

geom (geometry): Input geometry

Description¶

Returns the length of geom. This function only supports LineString, MultiLineString, and GeometryCollections containing linear geometries. Use ST_Perimeter for polygons.

Examples¶

SELECT ST_Length(ST_GeomFromWKT('LINESTRING(0 0, 10 0)'));
