A graphGis said to bedistancedmatchable if, for any matchingMofGin which edges are pairwise at least distancedapart, there exists a perfect matchingofGwhich containsM. In this paper, we prove the following results: (i) ifGis a cubic bipartite graph in which, for each, there exist two cycles,of length at mostdsuch that, thenGis distancematchable, and (ii) ifGis a planar or projective planar cubic bipartite graph in which, for each, there exist two cycles,of length at most 6 such that, thenGis distance 6 matchable.
