Both male and female mule deer experience parallel growth during their first year until males exceed females in body weight; chest girth; neck circumference; body, head, hindfoot, and hoof length; cranial breadth; and shoulder height.
Growth in mule deer during the first year is roughly parallel in males and females, but afterward, males, in general, exceed females in carcass weight, chest girth, neck circumference, body length, head length, cranial breadth, shoulder height, hindfoot length, and hoof length.
Carcass weight ranges from 45 to 150 kilograms in males, and 43 to 75 kilograms in females. Chest girth ranges from 80 to 117 centimeters in males, and 78 to 97 centimeters in females. Neck circumference ranges from 30 to 65 centimeters in males, and 26 to 38 cm centimeters females. Body length ranges from 126 to 168 centimeters in males, and 125 to 156 centimeters in females. Head length ranges from 28 to 35 centimeters in males, and 27 to 33 centimeters in females. Cranial breadth ranges from 11 to 16 centimeters in males, and 10 to 14 centimeters in females.
