The average adult has about 22 square feet (2 square meters) of skin, which is equivalent to the size of a standard doorway. This equates to approximately eight pounds (3.6 kilograms) of skin.
While the question asks for a "normal" size, there is no standard size for skin. Skin size varies depending on factors like age, height, and weight. However, it is generally understood that an average adult has roughly 22 square feet of skin.
It's important to note that skin size is not a fixed measurement. It can change over time due to factors such as weight gain or loss, sun exposure, and aging.
