Abstract
The purposes of this study is twofold: first, to standardize fingernail configuration of adult women in Korea; second, to set the basic data for the nail beauty industry. This study directly measures the size of fingernail configuration of 600 Korean women, ranging in age from 20s to 40s, with digital vernier calipers, radius gauge, and digital tape measure. The measurement result were analyzed by statistically. The descriptive data analysis provides baseline values for the transverse nail plate curvature of the thumb, index, middle, ring and little fingers. The hight of fingernail cross section was calculated by applying Srinivasa Ramanujan`s formula for the ellipse circumference and the results were used to analyze curvature of fingernail. The height-to-width ratio and curve length-to-width ratio of different digits indicate differences in fingernail curvatures: The thumbnail is the flattest, followed jointly by the little fingernail, index fingernail, then middle fingernail, and finally ring fingernail. The measured values of fingernail configuration can be applied as a basic data when designing for sizing systems of nail products or tor manufacturing various artificial nail tip and nail sticker products.
