Sagittal skeletal discrepancies are frequently assessed by Wits appraisal and point A–Nasion–point B (ANB) angle. These angular and linear measurements depend upon various factors and sometime produced inaccurate results. Beta angle has been introduced recently and possesses significant advantage over ANB and Wits appraisal, because it is independent of cranial landmarks and dental occlusion.  Aim To evaluate and correlate beta angle in various skeletal malocclusions and its correlation with Wits appraisal and ANB angle.  Material and Methods The present study was carried out in Bhojia Dental College and Hospital, Baddi, Himachal Pradesh, India. A total of 63 pretreatment lateral cephalograms (23 skeletal class I, 20 skeletal class II, and 20 skeletal class III) of patients aged between 14 to 25 years were included. Various landmarks and planes were identified and marked. Values of Wits appraisal, ANB angle, and beta angle were recorded. Comparisons of group were made with the chi-square test. Spearman correlation coefficient was calculated to see relation between different values.  Results Values of correlation coefficient of beta angle with Wits appraisal and ANB angle were –0.645 and –0.815, respectively.  Conclusion Overall beta angle showed strong correlation with Wits appraisal and ANB angle, however correlation of beta angle with Wits appraisal and ANB angle among various skeletal malocclusion groups (skeletal class I, II, and III) was not statistically significant.
