Types of psoriasis are defined by their location, severity and appearance. The most common type is plaque psoriasis (80% of people with psoriasis have this type).  A patient can develop more than one type of psoriasis.¹¹ It's important to know the type and severity of your psoriasis when talking about treatment plans with your doctor.

Location: Some forms of psoriasis can occur on any part of the body. Other types are typically found on specific parts of the body.

Severity: Each type of psoriasis can vary in its severity or how much of the body is involved. Erythrodermic psoriasis is probably the most severe form of the disease and can affect the entire body. To determine the severity of your psoriasis, click on the button.
