  We establish two-point distortion theorems for sense-preserving planar
harmonic mappings $f=h+\overline{g}$ which satisfies the univalence criteria in
the unit disc such that, Becker's and Nehari`s harmonic version. In addition,
we find the sharp two-point distortion theorem when $h$ is a convex function,
and normalized mappings such that $h(\D)$ is a $c$-linearly connected domain.
To do this, we use the order of this family.
