Triangle Face Shape: Is Your Jaw the Widest Part?
Triangle is the shape guides most often get backwards, because the same word is used for two opposite faces. This tool reads 468 landmark points, tells you which end of your face is actually wider, and scores all 8 face shapes. Nothing is uploaded.
Measure My Face Shape ›Quick answer: You have a triangle face shape when your jaw is the widest part of your face and your forehead is the narrowest, so the outline gets wider as it travels down. It is also called a pear face, and those two words mean the same thing. Before you follow any styling advice, read the next section: the term inverted triangle is used for two opposite faces on different websites, and picking the wrong one gives you advice that is exactly backwards.

What Is a Triangle Face Shape?
A triangle face widens as it goes down. Your jaw is the widest measurement on your face. Your cheekbones sit narrower. Your forehead is the narrowest of the three. Draw the outline and you get a shape that is broad at the base and tapers toward the top, which is where the name comes from.
The chin is usually broad or flat rather than pointed, and the temples often pull inward, which makes the upper face read even narrower than the tape says.
The measurable definition used on this page
- Jaw width is the largest of the three widths
- Forehead width is the smallest of the three
- Forehead sits at or below 95 percent of cheekbone width
- There is a clear gap between jaw and forehead, not a near tie
How strict is that gap? Ours is deliberately moderate: roughly 8 percent between forehead and jaw once both are measured against your cheekbones. Some calculators demand far more, one published tool requires the jaw to be at least 18 percent wider than the forehead before it will say triangle. That is a real disagreement, and it means a mildly bottom heavy face reads as triangle here and as something else there. We print the number so you can see which side of it you fall on.
Width always means cheekbone width here, on every page, in every ratio.
Triangle or Heart: One Question Settles It
These two are the most reversed pair in the whole category, and the reason is simple. They are mirror images. Both have a clear width imbalance between the top and the bottom of the face. The only difference is which end wins.
-
TriangleWidens on the way down. Jaw widest, forehead narrowest.Bottom is wider
-
HeartNarrows on the way down. Forehead widest, chin pointed.Top is wider
-
SquareNeither end wins. All three widths land close together.No imbalance
Triangle or heart? Compare top against bottom
Forget length, forget the chin, forget the jaw angle. Put two fingers at your temples, then move them to your jaw below your ears, keeping the same distance apart. If your fingers have to move apart at the jaw, you are triangle. If they have to come together, you are heart. That is the entire test.
Triangle or square? Check whether anything actually wins
A square face has all three widths landing close together, so no end dominates. A triangle has a real gap. If your jaw is only a fraction wider than your forehead, you are probably square with a slightly heavier jaw rather than a genuine triangle, and the tool will flag that as a borderline result rather than picking one quietly.
Read This First: The Naming Is a Genuine Mess
Face shape names are usually just inconsistent. This one is actively risky, because two sites can use the same term for two opposite faces, and the styling advice for those faces is reversed.
| Term you will see | What it usually means | How reliable is it |
|---|---|---|
| Triangle | Jaw widest, forehead narrowest | Consistent across almost every guide |
| Pear | Jaw widest, forehead narrowest | Consistent. Same face as triangle |
| Inverted triangle | Usually forehead widest, narrowing to the chin | Unreliable. Some guides use it for the jaw widest direction instead |
That third row is not a small quibble. One published guide describes an inverted triangle as a broader forehead tapering to a pointed chin. Another describes an inverted triangle as widest at the jawline, 15 to 25 percent wider than the forehead. Those are not two descriptions of one face. They are two different faces, pointing in opposite directions.
Why it matters practically. If your jaw is the widest part of your face, the advice is to add volume above the cheekbones. If your forehead is the widest part, the advice is to add weight at the jaw. Follow the wrong set and you deliberately widen the part that was already widest.
A Strong Jaw Is the Starting Point, Not the Problem
Triangle styling advice is written almost entirely as damage control. Minimise the jaw. Draw attention away from it. Balance it out. The lower face gets treated as something to manage.
The measurement says something plainer. A triangle face is not a wide jaw. It is a narrow forehead sitting above an ordinary one. The imbalance is real, but it runs in both directions, and you get to choose which end you adjust.
That is why every recommendation below is framed as adding width at the top rather than shrinking the bottom. It is the same balance, achieved without treating your own bone structure as a fault. It is also the more effective route in practice: you can add real volume to hair above the cheekbones, but you cannot make a jawbone narrower with a haircut.
One honest note on the numbers you will see quoted. Sites give triangle prevalence figures anywhere from under 9 percent to 15 percent, and none of them cite a study. There is no reliable population data for face shape distribution, so treat every percentage in this category, including any you see elsewhere on this topic, as an estimate rather than a finding.
How to Tell Without a Photo
Pull your hair fully back, and be thorough about the temples specifically. Triangle is decided by your forehead being the narrowest point, and hair sitting over the temples fakes exactly that. It is the most common cause of a false triangle result.
The two finger test, fifteen seconds
Hold two fingers at your temples, at the widest part of your forehead. Note the gap. Now move them straight down to the angles of your jaw, just below your ears, without changing the gap.
- Fingers need to spread apart at the jaw, that is a triangle
- Fingers need to squeeze together at the jaw, that is a heart
- Fingers fit at both, unchanged, that is square, round or one of the long shapes
The measured check
| Measurement | Where to measure | Triangle signature |
|---|---|---|
| Forehead width | Widest point across the forehead, on skin not hair | The smallest of the three widths |
| Cheekbone width | Arch to arch at the widest point | In between the other two |
| Jaw width | Jaw angle to jaw angle, below the ears | The largest of the three |
| Face length | Hairline centre, straight down to the bottom of the chin | Not decisive. Triangle appears on short and long faces alike |
Write the three widths in order. If they increase from forehead to jaw, you are a triangle. If they decrease, you are looking at heart or diamond. If they barely move, you are square, round, oblong or rectangle depending on length and jaw angle.
Triangle Face Shape Style Guide
One principle, and it points upward: add width and volume above the cheekbones, and keep the jaw line clean rather than crowded. You are lifting the narrow end, not shrinking the wide one. That distinction matters, because the things that genuinely work here are all additive.
The avoid lists matter as much as the recommendations, and almost nobody publishes them. All of it is guidance drawn from standard hairdressing, optical dispensing and tailoring practice, not rules.
Hair
- Curtain bangs or a side swept fringe, which widen a narrow forehead without hiding it
- Volume at the crown and temples, the most direct way to lift the upper face
- Layers starting at cheek level or higher, keeping weight above the jaw
- For men, a textured quiff or crop with height on top and tight sides below cheek level
- Blunt chin length bobs, which stop dead at the widest point of your face
- Volume sitting at jaw level, adding width where there is already the most
- Very flat crowns with heavy lower length, which exaggerate the taper
Glasses
- Browline frames, whose heavy upper rim adds weight exactly where the face is narrow
- Cat eye shapes, lifting attention up and outward
- Wider frames with detailing on the top rim
- Decorated or contrasting temple arms, adding width at the temples
- Bottom heavy frames, which pull the eye down toward the jaw
- Rimless styles, which leave the upper face with nothing to widen it
- Frames narrower than your cheekbones, making the taper look sharper
Beard
- Short, closely trimmed stubble, which keeps the jaw contained
- Tight sides with the length kept at the chin rather than the jaw angle
- A fuller moustache, which pulls a little attention upward
- Full wide beards, which add width to the widest point
- Mutton chops and heavy cheek growth, the same problem higher up
- Long jaw length growth, which extends the base of the triangle
Makeup
- Highlighter on the temples and forehead sides, bringing the narrow area forward
- Blush placed high on the cheekbone and blended outward toward the ear
- Fuller, slightly wider brows, which widen the upper face more than anything else
- Light contour along the jaw angles if you want to soften the base
- Highlighter along the jaw, which brings the widest part forward
- Blush placed low, near the jaw
- Thin narrow brows, which shrink an already narrow forehead
Outfits and necklines
- Boat necks and wide shoulder lines, which broaden the frame above the jaw
- Structured shoulders, balancing a heavier lower face
- Statement earrings sitting near eye level rather than dangling to the jaw
- Detail and pattern up near the collar
- Tight high collars, which press in at the jaw and emphasise its width
- Wide bottom heavy earrings, repeating the shape of the face
- Heavy low necklines with no shoulder structure
- Chokers, which draw a horizontal line right at the widest point
What This Detector Can and Cannot Do
The landmark detection is precise. One weakness matters far more on this shape than on any other.
Your forehead is the hardest width to measure from a photo, and triangle depends on it. The shape is defined by the forehead being the narrowest point, so anything that narrows the forehead reading pushes the result toward triangle. Hair over the temples does exactly that. So does a low or uneven hairline, a hat line, or a fringe swept to one side. Pull everything fully back before you scan, or the tool will confirm a triangle you may not have.
Face length is an estimate, because the model has no hairline landmark and the top point is extended by a fixed correction factor. This matters less here than on the long shapes, since triangle is decided by the progression of widths rather than by length.
Camera angle and lens type do the rest. Selfie lenses stretch the centre of the frame. Use a straight on photo at eye level from three to five feet away, chin level, back camera.
The Measurements tab is the more reliable route for a triangle face, because you can place a tape on your actual hairline instead of asking a camera to guess where hair ends and skin begins.
Triangle Face Shape: Questions People Actually Ask
What is a triangle face shape?
A triangle face shape is one where your jaw is the widest part of your face and your forehead is the narrowest, so the outline gets wider as it goes down. Your cheekbones sit somewhere in between. On this site the line is jaw width equal to or greater than cheekbone width, forehead width at or below 95 percent of cheekbone width, and a clear gap between the jaw and the forehead rather than a tie.
Is a pear face shape the same as a triangle face shape?
Yes. Pear and triangle describe the same face: jaw widest, forehead narrowest. Pear is the older term and still common in hairdressing, triangle is the term most measurement guides use now. The styling advice is identical, so the label does not change anything you should do.
What does inverted triangle face shape mean?
Be careful with this one, because it is used to mean two opposite things. Most guides use inverted triangle for a face that is widest at the forehead and narrows toward the chin, which is close to a heart shape. A few use it for the pear direction, widest at the jaw. Since the styling advice for those two is exactly reversed, ignore the label and check which end of your own face measures wider before following anything.
How do I know if I have a triangle face shape?
Pull your hair fully back and look straight into a mirror. Put two fingers at your temples, then move them to the angles of your jaw below your ears. If the jaw position is clearly the wider of the two and your forehead is the narrowest point on your face, that is a triangle. To confirm with numbers, measure forehead, cheekbone and jaw width and check that the jaw is the largest and the forehead the smallest.
What is the difference between a triangle and a heart face shape?
They are opposites, which is why they are the most reversed pair in face shape guides. A heart face is widest at the forehead and narrows to a pointed chin. A triangle face is widest at the jaw and narrows toward the forehead. One question settles it: is the top of your face wider, or the bottom?
What hairstyles suit a triangle face shape?
Anything that adds width and volume above the cheekbones. Curtain bangs, side swept fringes, crown volume, textured layers that start at cheek level or higher, and for men a quiff or textured crop. Avoid blunt chin length bobs and any volume that sits at jaw level, because both add width to the widest part of your face.
What glasses suit a triangle face shape?
Top heavy frames that add visual weight at brow level. Browline styles, cat eye shapes, and wider frames with detailing on the upper rim all widen the narrow upper face. Avoid bottom heavy frames and rimless styles that leave the top of the face bare, because they push attention downward to the jaw.
Is a triangle face shape rare?
There is no reliable published population study giving exact percentages for face shape distribution, so the figures you see quoted for triangle, which range from under 9 percent to 15 percent depending on the site, are estimates rather than measurements. What is measurable is your own set of widths, which the tool on this page prints for you.
How accurate is this triangle face shape detector?
The landmark detection is precise, but a triangle reading depends on comparing your forehead against your jaw, and the forehead is the harder of the two to measure from a photo. Hair covering the temples narrows the forehead reading and can create a false triangle result. Pull your hair fully back, or use the Measurements tab, which removes the problem entirely.
Can I use the detector without a photo?
Yes. The Measurements tab accepts four numbers taken with a soft tape: face length, forehead width, cheekbone width and jaw width. Any unit works because only the ratios matter. For a triangle face this is the more reliable route, because you can place the tape on your actual hairline rather than on hair.
