Some physical attributes of two common types of Iranian garlic cloves (white and pink) were identified and compared. A machine vision system was used to determine three di-mensions and both major and minor projected areas of garlic cloves at a moisture content of ۴۲.۴% w. b. The geometric mean diameter and sphericity were calculated, as well as the unit mass and volume of cloves were measured. In the moisture range from ۳۴.۹ to ۵۶.۷% w.b., the unit density, bulk density and porosity for both types were measured. Re-sults showed that the unit density, bulk density and porosity of cloves were affected sig-nificantly by moisture content (p<۰.۰۱). The type of garlic had a highly significant effect on the unit density and porosity (P<۰.۰۱), and a significant effect on the bulk density (P<۰.۰۵). The relationship between volume and dimensions of cloves was established using regression analysis. The effect of moisture content on physical properties of cloves was also expressed by appropriate equations.
