How long does it take fingernails to grow?

Timbo

The answer to this question is akin to the answer to the question 'How long is a piece of string?' You'll find that everybody's fingernail growth rates are different. It also depends how much fingernail you wish to grow. Some people leave their nails grow way passed the tips of their fingers (particularly females) and others prefer to cut them short. I have estimated (not a guess, mind you) that my thumbnail (right hand) is 16mm long. By memory it takes around 6-7 days for 3mm of growth to form. This quite obviously means that if I were to cut my nail right back to the skin and let it regrow it would take around one month (maybe slightly longer) for my thumbnail to regrow. I've also noticed in the past that my nails do not grow at the same rate. In conclusion the best way to find this out for yourself is to decide the question you want to answer and measure it on yourself. Oct 18 00, 2:40 PM

In mammals, the length and growth rate of nails is related to the length of the terminal phalanges (outermost finger bones). Thus, in humans, the nail of the index finger grow faster than that of the little finger; and fingernails grow up to four times faster than toenails. In humans, nails grow at an average rate of 3 mm (0.12 in) a month (as they are a form of hair). Fingernails require 3 to 6 months to regrow completely, and toenails require 12 to 18 months. Actual growth rate is dependent upon age, gender, season, exercise level, diet, and hereditary factors. http://en.wikipedia.org/wiki/Fingernails#Growth Aug 21 10, 8:12 AM
