Which cephalometric measure describes vertical facial dimensions using an angular value?

Vertical facial dimensions are best captured with angular cephalometric measures. The mandibular plane angle is the angle formed between the mandibular plane (lower border of the mandible) and a reference cranial base line, typically the SN line. This angle directly reflects how steep or flat the lower jaw sits relative to the cranial base, translating into the vertical height of the face. A normal range is about 24–26 degrees; larger values indicate a more vertical growth pattern with a longer lower face, while smaller values suggest a flatter, more horizontal pattern. In contrast, SNA and SNB describe the anteroposterior positions of the maxilla and mandible, not vertical dimensions, and the maxillary incisor angle relates to tooth inclination rather than overall facial height.
