Standing between 17 1/2 to 18 1/2 inches (females) or 18 1/2 to 19 1/2 inches (males), they fall into the medium category of size for dogs.
All schnauzers in Germany have their ears cropped; however, the American Schnauzer Club allows dogs to be shown with both cropped and natural ears. A docked tail is also typical.
The colors for a standard schnauzer can be pepper and salt or pure black. The typical pepper and salt color of the topcoat results from the combination of black and white hairs and white hairs banded with black. Acceptable are all shades of pepper and salt and dark iron gray to silver gray. Ideally, pepper and salt standard schnauzers have a gray undercoat, but a tan or fawn undercoat is not to be penalized. It is desirable for the dog to have a darker facial mask that harmonizes with the particular shade of coat color.
Also, in pepper and salt dogs, the pepper and salt mixture may fade out to light gray or silver white in the eyebrows, whiskers, cheeks, and leg furnishings, across the chest, inside the legs, and under the tail, throat, and body. Ideally, the black standard schnauzer should be a true rich color, free from any fading or discoloration or any admixture of gray or tan hairs.
The undercoat should also be solid black. However, increased age or continued exposure to the sun may cause a certain amount of fading and burning. A small white smudge on the chest is not a fault. Loss of color as a result of scars from cuts and bites is not a fault.
