The craniofacial characteristics of Iranian children were investigated in order to formulate cephalometric norms using Tweed and Steiner angular and linear measurements. The sixty-seven Iranian children studied included thirty-five girls and an average of 12.5 years and thirty-two boys with an average age of 12.4 years. The subjects were chosen on the basis of ethnic background (geographic area, religion, and language), good health, and normal occlusion. Thirty-two variables were tabulated, and statistical tests were employed.
