      To better understand the observed universality of their structure, we analyze the morphometry of a set of living and inanimate planar cellular partitions. We characterize them by the distributions of polygon reduced area, a scale-free measure of the roundedness of polygons. These distributions are fairly sharp and seem to belong to the same family. By comparing the frequencies of the polygon classes, we map all samples onto model tilings of equal-area, equal-perimeter polygons. We argue that the random two-dimensional patterns can be parametrized by their median reduced area alone.
