How Fast Do Human Fingernails Grow?
The answer to this question is actually a bit complex. The rate of growth of human fingernails varies, depending on the person, the nail in question, and the time of year. As a general rule, human fingernails grow between half an inch (one centimeter) and four inches (10 centimeters) per year, and a number of things can influence this growth rate. Incidentally, fingernails grow approximately five times as fast as toenails, for those who are curious.
