The clitoris is a small, rounded nub of tissue located at the top of the vulva, just above the urethral opening. What you can see from the outside, though, is only a fraction of the full structure. Most of the clitoris sits beneath the skin, extending several inches internally. Understanding both the visible and hidden parts helps make sense of why this organ looks and feels the way it does.
The Visible Part: The Glans and Hood
The only externally visible portion of the clitoris is the glans, a small, rounded bump that sits where the inner labia meet at the top of the vulva. In most people, the glans is roughly the size of a small pea. Measurements from clinical studies put the average glans at about 6 millimeters wide and 9 millimeters long, though this varies considerably from person to person.
A fold of skin called the clitoral hood (or prepuce) partially or fully covers the glans, similar to how a foreskin covers the head of a penis. The hood averages about 2 centimeters in length. In many people, the glans stays tucked inside this hood and is only visible when the skin is gently pulled back. In others, the glans peeks out naturally. Both are completely normal.
The shape of the hood itself varies. The most common form is a smooth, rounded arch, but it can also appear more pointed or ridge-shaped. Some hoods are thin and close to the body, while others are thicker or slightly puffy. The glans underneath can look rounded and convex, slightly oblong, cone-shaped, or flat at the tip. There is no single “correct” appearance.
The Hidden Structure Beneath the Surface
The glans is connected to a short shaft, or body, that angles upward and back beneath the skin of the pubic mound. You can sometimes feel this shaft as a firm, cord-like ridge just above the glans if you press gently. From the body, the clitoris splits into two leg-like extensions called crura that run along either side of the pubic bone, much like a wishbone shape. Two additional bulb-shaped structures sit deeper, flanking the vaginal walls on each side.
MRI research led by Australian urologist Helen O’Connell was among the first to map this full structure clearly. Her imaging showed that the bulbs, body, and crura form a connected cluster of erectile tissue that partially surrounds both the urethra and the vaginal canal. In total, the internal clitoris spans roughly 9 to 11 centimeters. So while what you see on the surface is small, the organ as a whole is considerably larger than it appears.
Why It’s So Sensitive
The glans is packed with nerve fibers in a way that’s unusual for its size. Research from Oregon Health & Science University counted more than 10,000 nerve fibers in the dorsal nerve of the clitoris alone, and additional smaller nerves push the total even higher. For comparison, the median nerve running through your entire hand, which is many times larger, contains only about 18,000 fibers. All that nerve density concentrated in such a small area is what makes the glans extremely responsive to touch, pressure, and vibration.
How It Changes During Arousal
Almost the entire clitoris, aside from the glans, is made of erectile tissue. This means it fills with blood and swells when stimulated, the same basic mechanism that produces an erection in a penis. During arousal, the internal bulbs can double in size. The crura engorge as well. This internal swelling often causes the outer labia to look puffier, and the glans itself may become more prominent and slightly darker in color as blood flow increases.
The effect on the visible glans varies from person to person. In some cases, swollen labia partially cover the glans during arousal. In others, the increased blood flow pushes the glans outward so it becomes more exposed and easier to see. Both responses are typical.
Changes Across a Lifetime
The clitoris looks different at various life stages. Before puberty, the glans and hood are smaller and less defined. During puberty, increased hormone levels cause growth in the clitoral tissue along with the rest of the vulva. The clitoris continues to grow slightly through adulthood; some studies note a modest size increase into a person’s 30s.
After menopause, declining estrogen levels cause the tissues of the clitoris, labia, and vaginal area to thin. The hood may loosen and drape more, sometimes fully concealing the glans underneath. The glans itself can become slightly smaller. These changes happen gradually and are a normal part of aging, though the clitoris retains its nerve supply and capacity for sensation.
Normal Variation Is Wide
There is no standard-issue clitoris. Glans size ranges from barely visible to noticeably prominent. Hoods can be long, short, thick, or thin. The glans may point slightly upward, downward, or straight out. Some people have a glans that’s always partially visible; others need to retract the hood to see it at all. Skin color ranges from pink to dark brown regardless of overall skin tone, and can differ from the surrounding labia.
If your anatomy doesn’t match what you’ve seen in diagrams or media, that’s expected. Medical illustrations typically show a single, simplified version. In reality, the range of normal is broad enough that no two look exactly alike.
