Nails are sold by a number followed by a 'd' and by length. The 'd' stands for penny, so 8d refers to an 8-penny nail, 16d to a 16-penny nail and so on. This is a way to indicate nail length. For example, a 2d nail is 1 inch long and a 4d nail is 1.5 inches long. The 'd' goes back to the time when the Romans occupied England and is associated with a Roman coin called the denarius, which was also the name for an English penny.

The 'd' in 4d nails stands for 'penny'

The 'd' in nail sizes goes back to the time when the Romans occupied England. Nails were hand-forged, one at a time.
