Average human adult has a fingertip that's about 1.75 inches long from tip to first crease. Fingertip is roughly oval-shaped and about half as wide as it is long. Thumb has two distinctive knuckle joints - the proximal interphalangeal joint (PIP) and distal interphalangeal joint (DIP), while the other fingers only have one knuckle. Fingernail length generally varies between 3-5 millimeters in diameter at base, but can reach up to 20% of overall nail size, being more significant in some people than others. Fingers that don't meet this size tend to have shorter fingers overall and less well developed second metacarpal bone in wrist. Average height for a finger is approximately two-thirds its length, from tip of fingertip to tip of the joint at base of nail plate. The human body naturally makes adjustments in proportion of fingers to allow for optimal grasp. Thumb to other four-finger ratio generally follows average human thumb-index gap.
