What is chin width?
Chin width is the distance straight across the chin, edge to edge of the bony chin button at the very bottom of the face. It is what decides whether a chin reads as narrow and pointed or broad and square, and it is one of the more sexually dimorphic features of the lower face: wide reads masculine, tapered reads feminine.
How It's Measured
How is chin width measured?
Chin width is the transverse distance across the chin protuberance, taken edge to edge of the bony chin from a front-facing photo. It measures the chin itself, not the jaw, so it is a much smaller number than the bigonial width between the two jaw angles.
- Chin protuberance: the bony prominence at the base of the chin, measured across its widest points.
- Not the jaw width: bigonial width spans the two back angles of the jaw; chin width is only the front chin button, so the two are read separately.
- Shape follows width: a narrow chin tapers to a point or a soft V, while a wide chin squares off the base of the face.
Read against the lower face, chin width tells you whether the chin finishes in a fine point or a broad, strong base, which is a large part of how masculine or feminine the jawline reads (Mealey et al., 1999).
Widening the chin on the same face moved the chin width from 29.8 mm to 30.9 mm, squaring off the base of the face. The measured change is modest because much of the wider look comes from the broader lower-face contour the edge-to-edge number does not fully capture. Same identity, same lighting, same framing.
Why It Matters
Why does chin width matter?
Chin width does more work than its size suggests. In one analysis of what actually drives female facial attractiveness, chin width came out as the second strongest single feature after overall averageness, ahead of most of the features people fixate on (Baudouin & Tiberghien, 2004). A narrower, cleaner chin tends to read as more attractive on a female face, which is why so many aesthetic complaints about the lower face are really about width.
It is also one of the clearest sex signals in the lower face. Testosterone drives growth of the jaw and chin at puberty, so a wider chin reads as masculine and a more slender, tapered chin as feminine (Mealey et al., 1999). Modern facial analysis confirms the pattern, with the lower face measurably wider in men than in women (Liu et al., 2023).
Because of that, chin width is a lever aesthetic practitioners actively use, building a stronger, wider chin in men and a more slender one in women when they shape the lower face (Goodman, 2015). There is no universal ideal number, only what balances a given face, so the cards and table below describe how chin width reads rather than prescribing one figure.
Narrow
Softer, more feminine
Balanced
Proportionate taper
Wide
Stronger, more masculine
Chin width is read against the jaw and lower face, not as a fixed number. A narrower, tapered chin reads softer and more feminine; a wider chin reads stronger and more masculine. Bone structure shifts the balance.
Demographic Variants
Chin Width by Group
Chin width is one of the most sexually dimorphic parts of the lower face, so it is read mainly against sex and overall lower-face proportion rather than a single target. Each row links to the source.
Group | How chin width reads | Source |
|---|---|---|
Men | Wider, squarer chin on average, tracking a broader lower face | |
Women | More slender, tapered chin; a narrower chin tends to rate as more attractive | |
Puberty and development | Testosterone widens the jaw and chin, setting much of the adult chin width | |
Aesthetic shaping | Practitioners build wider chins in men and more slender ones in women |

Frequently Asked Questions
A wide chin is a broad, squared-off chin protuberance, and it reads as a masculine trait because testosterone widens the jaw and chin during puberty (Mealey et al., 1999). On its own it is neither good nor bad; it simply strengthens the lower face and is more common and better balanced on male faces than female ones.
On a female face, a narrower, more tapered chin does tend to rate as more attractive. Chin width is one of the strongest single predictors of female facial attractiveness, second only to overall averageness in one analysis (Baudouin & Tiberghien, 2004). A very pointed chin can look sharp, though, so balance against the rest of the lower face matters more than simply being narrow.
Chin width is mostly set by the bone. The chin and jaw grow under the influence of sex hormones at puberty, so a wider chin is largely inherited and develops as part of a broader lower face, which is why it is more common in men (Liu et al., 2023).
Yes, within limits. Filler and implants can build a chin wider and stronger, while surgical reduction can narrow a broad chin, and practitioners routinely shape chin width toward a stronger male or a more slender female look (Goodman, 2015). Makeup contouring can soften the appearance temporarily, but real changes in the bone are structural.
