Wider Below, Narrower Above
The face gradually widens from the forehead down to the jaw. The forehead is the narrowest horizontal measurement, while the jaw is the widest - the opposite of the heart shape.

Triangle Face Shape Guide: Features & How to Identify It
A triangle face shape is relatively wider through the jaw and narrower through the forehead. Use this guide to check those proportions, compare similar shapes, and get a personal reading from the Face Shape Detector without treating the label as a fixed beauty rule.
- Jaw is the widest part of the face
- Forehead is noticeably narrower than the jawline
- Face widens progressively from temples to jaw
Features
What Is a Triangle Face Shape?
A triangle face is defined by a jaw that is wider than the forehead, creating a shape that broadens from top to bottom. Unlike the heart face (which is essentially the inverted version), the triangle face has its widest point at the lower third. The jawline tends to be strong and prominent, and the chin is typically broad rather than pointed. Triangle here means a relatively wider jaw and narrower forehead; it is not the same label as inverted triangle, which describes the opposite width pattern.
Jaw Is the Widest Point
The jawline is wider than both the cheekbones and the forehead. This bottom-heavy width distribution is what distinguishes the triangle from shapes like diamond (widest at cheekbones) or oval (widest at cheekbones with balanced proportions).
Angled Side Profile
The sides of the face angle outward from the temples toward the jaw, creating visible diagonal lines. This progressive widening gives the face its characteristic triangular or pear-like silhouette.
Strong, Broad Jawline
The jawline is prominent and well-defined, often with a soft-square quality. The chin tends to be broad rather than pointed, contributing to the wide lower third of the face.
Measure and identify
How to Measure a Triangle Face
To confirm a triangle face shape, measure three horizontal distances: forehead width (across the widest part of the forehead), cheekbone width (across the outer points of the cheekbones), and jawline width (across the widest part of the jaw). In a triangle face, the jaw measurement is the largest, followed by cheekbones, then forehead. You can also use a face shape analyzer to get a quick digital assessment of your proportions. Facial anthropometry research treats forehead, cheekbone, jaw, and face length as related proportional observations rather than a single universal beauty ratio. Facial dimension review on PMC.
Self-check
Self-Check: Do You Have a Triangle Face?
Use a front-facing mirror or photo and work through these four checks. Camera distance, head tilt, and expression can change how proportions look, so treat the result as an observation rather than a diagnosis.
1
Straight-on view
Face the camera or mirror head-on. Check whether the lower face looks relatively wider than the forehead.
2
Hairline and jawline
Keep the forehead and jaw corners visible. A triangle reading has more width through the jaw than through the upper face, which is the opposite of heart / inverted-triangle patterns.
3
Camera distance
Use a natural arm-length distance. Extreme close-ups can change forehead-to-jaw balance and confuse nearby types.
4
Neutral expression
Keep a relaxed jaw. Clenching or smiling can temporarily change lower-face width and hide the deciding contour.
If your jaw is the widest measurement, your face widens from top to bottom, and your jawline is prominent with a broad chin, you most likely have a triangle face shape. For a photo-based comparison of nearby types, use the Face Shape Detector. Camera-distance proportion study.
Compare
Compare similar face shapes
The triangle face is most often confused with four other shapes. Here is how they differ.
Triangle vs. Square
Shared: Both have strong, defined jawlines and angular lower faces.
Deciding difference: A square face has a forehead that roughly matches the jaw in width, creating even proportions. A triangle face has a forehead that is noticeably narrower than the jaw, producing the characteristic bottom-heavy silhouette.
Square face shapeTriangle vs. Heart
Shared: Both shapes have an uneven forehead-to-jaw ratio, creating a tapered appearance.
Deciding difference: They are essentially inversions of each other. The heart face is widest at the forehead and narrows to a pointed chin, while the triangle face is widest at the jaw with a narrow forehead. A heart face is sometimes called an "inverted triangle" - the naming can cause confusion, but the width distribution is opposite.
Heart face shapeTriangle vs. Diamond
Shared: Both have a narrow forehead relative to other facial measurements.
Deciding difference: A diamond face is widest at the cheekbones, with both the forehead and jaw being narrow. A triangle face is widest at the jaw, with the cheekbones falling between the forehead and jaw in width.
Diamond face shapeTriangle vs. Round
Shared: Both shapes can share individual contour cues depending on photo angle and hairline.
Deciding difference: The deciding difference is which width zone dominates and how the jaw and chin finish. Compare triangle and round side by side before locking a label.
