In this paper, two versions of Landau–Bloch type theorems for biharmonic mappings are provided by applying the geometric method and establishing better coefficient estimates for bounded and normalized planar harmonic mappings. In particular, we pose a conjecture for the sharp version of Landau–Bloch type theorem for certain bounded harmonic mappings. The results in the presented paper improve a related result of the earlier author.
