The visible part of the clitoris looks like a small, rounded nub of flesh located at the top of the vulva, where the inner lips meet. It sits beneath a fold of skin called the clitoral hood, which may cover it completely, partially, or barely at all. What you can see from the outside is only a fraction of the full structure, which extends several inches inside the body.
The Visible Part: Glans and Hood
The external portion is called the glans. It’s roughly 20 to 30 millimeters long (about the size of a pea or small bean) with a similar width, though this varies widely from person to person. The glans sits just above the urethral opening and is partially or fully covered by the clitoral hood, a small flap of skin formed where the inner labia meet at the top of the vulva.
The hood itself comes in different shapes. Research examining clitoral hood anatomy identified four distinct forms: horseshoe, trumpet, coffee bean, and tent. Some hoods are snug and closely wrapped around the glans, while others drape more loosely. The hood and the inner labia are actually separate structures, even though they appear to merge at the top of the vulva. All of these variations are normal.
Color ranges from pink to dark brown, depending on your overall skin tone. The tissue of the glans is mucosal, similar to the inside of your lip, so it tends to appear slightly different in color and texture compared to surrounding skin.
The Internal Structure You Can’t See
Most of the clitoris is hidden beneath the skin. MRI imaging reveals a wishbone-shaped structure that extends internally on both sides of the vaginal canal. The full clitoral complex includes three main parts: the glans (the external nub), a cylindrical body about 10 millimeters wide that angles back beneath the pubic bone, and two legs called crura that branch out like a wishbone and run along the pelvic bone.
Alongside the crura sit two oval, elongated structures called vestibular bulbs. These surround the urethra and vaginal opening and swell with blood during arousal. Together, the entire clitoral complex spans roughly 9 to 11 centimeters in total length. So while the visible part is small, the organ as a whole is comparable in size to a penis.
Why It’s So Sensitive
The clitoris is the only organ in the human body that exists solely for pleasure. It has no role in reproduction or urination. A 2022 study from Oregon Health and Science University counted the nerve fibers in the clitoral dorsal nerve and found an average of about 10,281 nerve fibers, more than previous estimates of 8,000 that had been cited for decades. And because the clitoris also has additional smaller nerves beyond the dorsal nerve, the true total is even higher. That density of nerve endings packed into such a small area is what makes it extraordinarily responsive to touch.
How It Changes During Arousal
The clitoris doesn’t look the same all the time. During the early stages of arousal, increased blood flow causes the glans and internal structures to swell, similar to an erection. The glans may become more visible as it emerges slightly from beneath the hood, and the tissue can deepen in color as blood fills the area. At peak arousal, the clitoris becomes extremely sensitive, sometimes to the point where direct touch feels too intense. After orgasm or when arousal fades, the swelling subsides and everything returns to its resting size and position.
How It Changes Over a Lifetime
The clitoris is not static. It develops during puberty as hormone levels rise, and it continues to change with age. During the reproductive years, circulating estrogen and progesterone help maintain the tissue’s fullness and sensitivity. After menopause, declining hormone levels can cause the surrounding tissue to thin and the clitoris to become somewhat smaller. This is part of a broader process called urogenital atrophy that also affects the vaginal walls. For some people, this thinning changes sensation during sexual activity, occasionally turning previously pleasurable touch into discomfort.
The internal bulbs also change. MRI data shows that bulb width averages about 8 millimeters in premenopausal women and shrinks to about 5 millimeters after menopause. The clitoral body itself stays roughly the same width regardless of age.
Normal Variation Is Wide
There is no single “normal” appearance. Glans size, hood coverage, color, and positioning all vary significantly. Some people have a glans that’s easily visible without retracting the hood. Others have a hood that fully covers the glans, making it less obvious at a glance. Both are typical. The inner labia may be symmetrical or uneven, short or long, and the way they frame the clitoral hood differs from person to person.
Clinically, an unusually enlarged clitoris (called clitoromegaly) is defined by a specific measurement: multiplying the width of the glans by the length of the shaft. A result under about 4.35 mm² is considered typical, while a result above 10 mm² may warrant evaluation. This is rare and usually linked to hormonal conditions. For the vast majority of people, whatever their clitoris looks like falls well within the range of normal human anatomy.
