Materials Method: Lateral cephalogram 46 (21 males 25 females) Class I profile were selected from the archives Department orthodontics, Dhulikhel Hospital. Manual tracing measurement (NLA) 2 related that affects i.e., lower border Frankfort horizontal plane (N/FH), (L/FH) done. Descriptive analysis was carried out Student’s t-test used compare mean differences between subjects. Result: values NLA, N/FH L/FH 100.22 ± 10.36, 22.78 7.46 79.46 8.29 respectively. NLA 100.48 10.07 103.68 10.57 Similarly, 21.90 6.65 23.52 8.14 females. Also, be 78.62 7.39 80.16 9.07 Conclusion: Normative established. sexual dimorphism observed all 3 higher compared
