A 20d nail typically measures 3 inches in length. The "d" in nail sizing stands for "penny," a term that dates back to the Middle Ages, reflecting the price of nails. The larger the number before the "d," the longer the nail. Therefore, a 20d nail is one of the larger common sizes used in construction and carpentry.

The magnification of a lens is calculated using the formula M = 1 + D/f, where M is the magnification, D is the lens power in diopters (20D in this case), and f is the focal length of the lens in meters. Without knowing the focal length of the lens, we cannot determine the exact magnification.

An 8 penny nail (abbreviated as 8d) is 2.5 inches in length. A 10 penny nail (10d) is 3 inches in length.
