No, there is not a disorder for being too tall. There is, however, a condition called Marfan Syndrome that can cause people to be unusually tall. Marfan Syndrome is a genetic disorder that affects the connective tissue in the body.
People with this condition may have a long, thin body type and abnormal arm and leg proportions that result in an unusually tall appearance. They may also have longer fingers and toes, heart defects, vision problems, and other physical characteristics related to the disorder.
While some people with Marfan Syndrome may appear very tall, their height is usually within the normal range for their age group. Those affected by the condition may require treatment to manage the symptoms.
