AbstractMeasurements on the normal human nails were done in 75 males and 35 females subjects. The average length and breadth of each digit was more in males than in females but the L: B ratios were nearly the same. The length was largest in thumb and smallest in little finger in that descending order. The breadth goes on decreasing from thumb, middle, ring, index and little finger. The L:B ratio is maximum in the thumb and minimum in the index finger. The shape of the nails is classified as square nail long nail, cylindrical nail, large nail and broad nail. Another classification of the shape based on L:B is suggested; it is as long square and broad. The broad is classified from grade I to VIII and the long in grade 1 to II. No significant difference was found in right handed and left handed persons.
