Evaluation of the Length & Width of all the Nails of Hand – An Observational Survey Study

Several conditions can affect the configuration of a person's fingernails. While the shape and curvature of the nails may offer diagnostic insights into various diseases, limited studies have accurately defined normal fingernail Anthropometry. In our study, we measured the length and width of fingernails of the upper limbs of 100 volunteers with healthy nails. The greatest nail width was found on the thumb, followed by the index, middle, ring, and little fingers. Width of fingernail was influenced by handedness and age. Our quantitative data on fingernail measurement can serve as a reference for diagnosing nail-related diseases and deformities, as well as for guiding reconstructive or aesthetic nail surgeries.
