We report a numerical study of quantum transport in zigzag graphene nanoribbons with varying edge-disorder profile. The transport length scales, such as the elastic mean-free paths and the localization lengths, are shown to fluctuate by orders of magnitude depending on the topology of edge irregularities as well as their correlation degree. This might result in considerable sample-to-sample fluctuations of the corresponding transport gap, whose occurrence has been recently discussed both experimentally and theoretically.
