Key points
- Geometric morphometrics visualizes shape differences using Procrustes analysis and deformation grids.
- Allometry, the size-shape relationship, is estimated by regressing shape coordinates on centroid size.
- Adult male facial shape exhibits cues to body size, resembling ontogenetic allometry.
- Facial allometry may confound studies on face perception and human mate choice.

Abstract
We briefly and informally review the concepts of size, shape, and form and how they are estimated in geometric morphometrics using Procrustes analysis. We demonstrate how deformation grids and reconstructed shapes or forms can be used as powerful tools to visualize shape and form dierences. Complexpatternsofindividualor groupdierencescanbestudiedeectiv elybyordinations of shape space or form space. Allometry, the statistical relationship between size and shape, is estimated in geometric morphometrics by regression of the Procrustes shape coordinates on centroid size. We illustrate these methods by an application to human face shape. We reveal shape cues to body size in the adult male face, partly resembling ontogenetic allometry. Facial allometry might thus be an important confounding factor in studies of face perception and human mate choice.
