Men generally have larger foreheads than women. This difference is measurable in terms of both height and width.
Forehead Measurements: A Comparative Analysis
Studies have shown significant differences in forehead dimensions between men and women. For example, research indicates that mean forehead height above the lateral eyebrow is greater in men (4.16 cm) compared to women (3.51 cm). Similarly, forehead height above the eyebrow peak is also significantly larger in men (5.55 cm) compared to women (4.34 cm).

It's important to note that these are average measurements; individual variations exist within each gender. However, the overall trend suggests a statistically significant difference in forehead size between men and women.
