How much of your body is affected?

Dermatologists measure plaque psoriasis as mild, moderate, or severe. The severity of your psoriasis depends on how much of your body is affected, also known as your body surface area (BSA). Your entire hand (the palm, fingers, and thumb) is equal to about 1% of your BSA.

Mild psoriasis covers less than 3 percent of the body.
Mild psoriasis covers less than 3 percent of the body.
