Height is one of the parameters of anthropometric measurements to determine the physical identity of a person, especially in the process of forensic identification. The forensic experts have long been doing research on the estimated height based on the length of a particular body part, and one of them is the length of the ulna bone. This study aimed to determine the relationship between the length of the ulna bone height, and try to get a height regression formula based on the length of the ulna bone in Acehnese. This study was an observational study with cross sectional method. Research subjects are students numbered 88 people were taken to the cluster method. Anthropometric measurements were carried out in the form of height and length of the ulna bone. Data will be analyzed statistically with the Kolmogorov-Smirnov test and simple linear regression. Statistical analysis showed a significant relationship between the length of the ulna bone height in male behavior with r = 0.736 and r = 0.710 women with sig = 0,000 (sig.
