Wolf size in Twilight Vale is closely connected to rank and bloodline. Alpha wolves are the largest, typically standing between 180–200 cm at the shoulder. Beta wolves generally range from 160–180 cm, while Gamma wolves stand between 140–160 cm. Wolves outside these rank-defined bloodlines typically remain below 140 cm at the shoulder.

Individual height can vary within these ranges, but the physical difference between ranks remains clearly visible in wolf form.
