Nails are sold by a number followed by a 'd' and by length. The 'd' stands for penny, so 6d refers to a 6-penny nail, 8d refers to an 8-penny nail, and so on. This sizing system goes back to the time when the Romans occupied what is now England. The 'd' is associated with a Roman coin called the denarius, which was also the name for an English penny.

The 'd' goes back to the Roman occupation of England
The 'd' in 6d nails goes back to the Roman occupation of England. The 'd' is associated with a Roman coin called the denarius, which was also the name for an English penny. Nails were once hand-forged, one at a time, and the number and the 'd' indicated the price of the nail. For example, some say that a hundred 3-and-a-half-inch nails would have cost 16 pennies and thus became known as 16-penny nails. Others say that one 16d (3-and-a-half-inch) hand-forged nail cost 16 pennies. The 'd' designation persists even in modern building codes, although retail boxes of nails are now marked with the penny size as well as the length in inches.

Nails are sold by number and length
The penny size of the nail is a way to indicate nail length. So, for example, 8d refers to an 8-penny nail, 16d to a 16-penny nail, and so on. This sizing system is still used today, even though nails are no longer hand-forged. Retail boxes of nails are marked with the penny size as well as the length in inches.
Nail sizes can also be referred to by their length in inches. For example, a 2-inch nail is commonly referred to as a "2-penny" nail. This is a less confusing way to refer to nail sizes, as the length is explicitly stated.
Nail sizes are important to understand when purchasing nails for a project. The length of the nail will determine how much weight it can support and how much material it can penetrate. For example, a longer nail will be able to penetrate thicker material and support more weight than a shorter nail.
