# ST_Scale

This function scales the geometry to a new size by multiplying the ordinates with the corresponding scaling factors provided as parameters `scaleX` and `scaleY`.

<Note>
  This function is designed for scaling 2D geometries. While it currently doesn't support scaling the Z and M coordinates, it preserves these values during the scaling operation.
