The average height of a female's forehead is 2.4 inches (6 cm). This is measured from the bottom of the hairline to the top of the eyebrows. It is important to note that these are just averages, and there is a wide range of variations in forehead size. Forehead size can be affected by a number of factors, including genetics, age, and sex.\r
Some women have larger foreheads, while others have smaller foreheads. There is no need to feel self-conscious about the size of your forehead. If you are concerned about the appearance of your forehead, you can talk to a dermatologist or other healthcare professional. They can help you determine if there is a medical cause for your concern and recommend treatment options, if necessary.
