Southdown sheep reach the grapes on the vines. Baby Doll breeders claim that their sheep are closer to the original English Southdown than are the commercial Southdown sheep being grown today. Mature weights for rams range from 190 to 230 lb (86-104 kg); ewes weigh from 130 to 180 lb (59-81 kg). From mature ewes, fleece weights are between 5.0 and 8.0 lb ((2.5 - 3.6 kg) with a yield of 40% to 55%. The fleeces are considered medium-wool type with a fiber diameter of 23.5 to 29.0 microns and a numerical count of 54 to 60. The staple length ranges from

For a "true" skew arch the ratio of the span on the square to the span on the skew is equal to the cosine of the skew angle, but for a ribbed skew arch this ratio is made even less favourable due to the steps in the barrel wall.
