The longest fingernails on a pair of hands (female) belong to Diana Armstrong (USA) and measure 1,306.58 cm (42 ft 10.4 in), as verified in Minneapolis, Minnesota, USA, on 13 March 2022.
Diana has not cut her nails since 1997 and has no plans to ever cut her nails again. She dedicates the nails to her daughter who passed away unexpectedly at the age of 16. The two of them would often do their nails together, so Diana chose to never cut her nails again as a way of keeping her daughter's memory close. It now takes approximately 5 hours and more than 1 whole bottle of nail polish to paint one nail. They are filed using a power tool.
