While a few mules can carry live weight up to 160 kg (353 lb), the superiority of the mule becomes apparent in their additional endurance.

The median weight range for a mule is between about 370 and 460 kg (820 and 1,000 lb).

Mules also tend to be more independent than most domesticated equines other than its parental species, the donkey. The mule is valued because, while it has the size and ground-covering ability of its dam, it is stronger than a horse of similar size and inherits the endurance and disposition of the donkey sire, tending to require less feed than a horse of similar size.
