What is the penny size of a nail? There is a special classification of nail sizes that originated in England – Penny system, the nail size was originally named after the price of 100 nails of a given size. The “d” is the symbol for the penny. For example, 16d stands for 16 penny nail. Now, the term corresponds to the measurement of nails from the head to the tip, which is the nail length, specified by a digit and the letter “D”, which means “penny size”. So, a 2d nail is 1 inch long. More common nail sizes: a 4d nail measures 1.5 inches, a 6d nail is 2 inches long, an 8d nail is 2.5 inches long, a 12d nail is 3.25 inches long, and 16d nails are 3.5 inches long.
