If you want to learn whether or not you have a prominent forehead, you need to understand that foreheads come in different shapes. Often, people will mistake a large forehead for one that is irregular or rectangular.

How to Tell If You Have a Big Forehead

There are five typical forehead shapes.

• Round
• M-shaped
• Rectangular
• Bell-shaped
• Triangular

For people with a round-shaped forehead, the crown of their head will look like a half-circle. This is the third most common shape among men (31%) and the second in women (28%).

M-shaped foreheads are closely associated with the widow’s peak, a triangle of hair emerging from your hairline into your forehead. The widow’s peak forms an M-shape between the hairline and the brow. It is the most common shape among men (46%) and third among women (19%).

Rectangular foreheads are self-explanatory but can appear more square if a person has a narrow face. Around 31% of men have rectangular foreheads, and 30% of women have them.

Bell-shaped is similar to a round forehead except more ovular. It is the least common in women (5%) and the second least in men (4%).

Finally, the triangular forehead involves the sides of your forehead sloping inward. Around 2% of men have triangular foreheads, and 18% of women have them.

Is Your Forehead Big?

After you understand the forehead shapes, you can begin to assess your face. Find your forehead shape based on the descriptions above, so you know where to take your measurements.

It would be a mistake just to look up forehead size averages and compare yourself. Most of those averages don’t include where to take the measurements, and they also do not consider different shapes.

While you might be wider than average, it could just be because you have a rectangular shape instead of a round one. Always measure your forehead from its longest and widest sections to get the most accurate measurements.
