In most applications the Gauss–Krüger is applied to a narrow strip near the central meridians where the differences between the spherical and ellipsoidal versions are small, but nevertheless important in accurate mapping.

In constructing a map on any projection, a sphere is normally chosen to model the earth when the extent of the mapped region exceeds a few hundred kilometers in length in both dimensions.
