What is the difference between a standard schnauzer and a miniature schnauzer?

Well obviously a miniature dachshund is smaller than a regular sized dachsund. I own a three year own longhaired miniature dachshund and she is considerably smaller than a standard sized, but they are not actually very different other than size. They are still what I would consider a small dog trapped in a big dog's body. (:
