Males are universally reported to possess larger facial soft‐tissue thickness (FSTT) than females, however, this observation oversimplifies the raw data yielding an underpowered assessment of FSTT sex‐patterning where: differences are small ( η 2 M, by +16%). Consequently, while the sexes share similar raw values, females possess much larger FSTTs for their relatively lighter bodies. The relative FSTT difference was 2.7× larger than the raw mean difference. Sex differences in FSTT are of larger magnitude and reversed direction in mass normalized data. Contrary to popular thought, females possess much larger FSTTs than males owing to their generically lighter bodies (−18 kg). These data patterns help explain why the pooling of sex‐categorized FSTT does not jeopardize the sex‐difference—it is encoded more strongly in terms relative to body mass
