Fingernails grow slowly – roughly a hair’s width a day – but that growth adds up over the long term. Let your grow wild and you might eventually beat the Guinness World Record set by Melvin Boothe, whose untamed claws reached a combined length of more than 32 feet (nearly 10 m).
Several factors affect the rapidity of nail growth. Fingernails, for example, grow faster during daytime than at night. In addition, fingernails grow at a greater clip in the summer, for the young, and slower for older people and in the winter. The middle, ring and index fingernails grow the fastest, while the thumb and little finger lag behind.
