The triangle read in one frame: a strong jaw, a narrower forehead, and everything above the jaw kept deliberate. This page is the styling that follows from it.
Checked and updated October 2026
The short answer: your jaw is your widest line and your forehead your narrowest, so every good decision on this page does the same job: it adds width or weight to the top half of your face and keeps the bottom half calm. Hair: volume and texture on top, sides tapered gradually, never shaved tight. Frames: top-accented and browline styles, the one shape they truly flatter. Beard: short and close at the jaw, or none. Collars: spread. The decision table below is the whole system for your shape on one screen. If you have not measured yet, start with the Face-Shape Decoder hub: three measurements, two minutes, and this page is either confirmed as yours or ruled out honestly.

Confirm it is triangle
The full method lives on the Decoder hub; here is the short version, because this shape is decided by a single comparison. Take the three hub measurements (face length, forehead width, jawline width) with your hair pushed back. Triangle reads like this: the jawline width is greater than the forehead width. It is the only one of the seven shapes where the jaw out-measures the forehead, and that one fact is the whole identification. Face length usually lands between the width and one and a half times the width, and the outline widens as it descends: narrower at the temples, widest at the jaw.
The two confusions worth ruling out. Triangle or square: on a square face the forehead and jaw measure close to equal, and the haircut answers differ (square wants softness; triangle wants top width), so the tape settles a real question. Triangle or oblong: an oblong face runs much longer than wide with forehead and jaw in a similar range; a triangle face widens as it goes down, whatever its length. And judge the shape with the beard you actually wear: a fuller beard redraws the jawline, and the hub FAQ explains how it can move a borderline reading one step in this direction.
One more piece of housekeeping: some guides call this outline pear. Same shape, same guidance, different label. We file it as triangle, matching the barbering and fitting practice the Decoder is compiled from. The guidance on this page is proportion, not grading: a strong jaw is a feature with a styling logic, and the logic is simple enough to fit in one sentence. Width goes on top, and the jaw stays quiet.
Haircuts: width goes on top
Your forehead is the narrowest part of the frame, so the haircut's job is to lend it width. That means volume, texture and visible length through the top, and sides that taper down gradually and keep a little of their own length. The failure mode is just as specific: sides clipped tight and short leave the jaw standing alone at full width, unopposed, and the face reads wider at the bottom than it already is. Almost every bad haircut on this shape is that one mistake wearing different names.
Textured crop with height: the default. Short to medium on top with real texture, worn up and slightly forward, it adds both height and visual width where the forehead runs narrow. It asks little in the morning and survives growing out, which is why it is the recommendation if you only take one from this page. Side part with body: the office version. The part itself draws a line across the top of the face, and the body on either side of it widens the upper read. Keep the sides at a scissor taper or a low, gradual clipper taper; the shape of the side matters more than its shortness. Longer styles through the top: the committed version. Grown-out tops, swept back or falling as loose curtains with volume, widen the upper face the most of anything here. The condition is where the length sits: through the top, not hanging at the sides of the jaw, where it adds width to the one line that needs none.
With care: a tall top with a fade can work, but the fade is the risk, not the height. Ask for the lowest, softest version, or a taper, and stop well short of skin. Fights your shape: tight tapered sides under a flat, short top; an even all-over buzz, which publishes your exact proportions with no styling answer at all; and long hair parted in the middle and hanging straight past the jaw on both sides.
Say this to your barber
"Keep the length and the texture on top, and taper the sides low and gradual. Do not clipper the sides tight. I want the top to read wider than my jaw, not narrower." Four sentences, and the cut is decided before the cape is on.
The triangle decision table
This table expands the triangle row of the hub decision matrix into the full working version for this shape, compiled by our data team from standard barbering and eyewear fitting practice and re-checked on the same cadence as the hub. It is the one object to screenshot from this page: four decisions, each with the answer, the careful version, and the one that fights your shape.
| Decision | Works | With care | Fights your shape |
|---|---|---|---|
| Haircut | Textured crop with height; side part with body; longer top with volume | Curtains with volume; tall top with a low, soft taper | Tight sides under a flat top; even all-over buzz; length hanging at the jaw |
| Frames | Browline and top-accented; strong top bar; at least as wide as your forehead | Soft rectangles with a heavier top rim | Bottom-heavy frames; narrow frames; teardrop lenses |
| Beard | Short and close at the jaw; stubble; clean-shaven | Short boxed beard, fuller at the chin point only | Flared sides; a long beard worn wide at the bottom |
| Collar | Spread and semi-spread | Classic point with the top button open; band collar | Narrow point collars, buttoned to the top |
How the four rows connect: each one moves visual weight in the same direction, up. Hair builds the top of the head, frames build the top of the face, the beard stays out of the jaw's way, and the collar widens the frame the face sits in. No single row has to carry the whole correction, which is why the with-care column exists: take the rows you like and let the others be ordinary.
Glasses: the browline's one true home
Frames sit at the centre of the face and either echo its lines or counter them. A triangle face needs the counter in one specific place: the top line. Your forehead carries the least width of any feature, so the right frame lends it some, with a strong top bar, a browline or top-accented build, and a total width at least equal to your forehead's. The frame itself becomes the widest-looking line in the upper face, and the jaw below it settles back into proportion.
This is the shape the browline was made for. On most faces a browline stacks extra presence on an already adequate forehead; on yours it fills a genuine gap, and the hub matrix says it plainly: this is the one shape a browline flatters. Heavy top rims on otherwise light frames do the same job more quietly. With care: soft rectangles with a heavier top rim, and light metal frames with a defined top bar. Fights your shape: bottom-heavy frames, which put their weight on your widest line's level; narrow frames that sit inside the width of your forehead and make it look narrower still; and teardrop or aviator lenses, which widen as they descend and mirror the jaw's own slope. Sunglasses follow the same rule as glasses: top line strong, bottom line quiet.
Beards: quiet at the jaw
A beard redraws the jawline, and the jawline is the line this whole system reads first. On a triangle face that makes the beard the highest-stakes grooming decision on the page: grown with bulk at the jaw corners, it widens the widest line a second time, and the face tips from strong-jawed to bottom-heavy. Grown with discipline, it costs you nothing and softens nothing you need. The hub puts the general rule this way: a fuller beard can move a face one step toward square or triangle. If you are already triangle, that step is the direction you are managing against.
The working versions. A short boxed beard trimmed close along the jaw sides, with neat cheek lines, is the full-beard answer: present, deliberate, and no wider than the jaw it sits on. If you want length, put it at the chin point only, where extra length reads as face length rather than width; a beard that lengthens slightly toward a soft point at the chin is the one long version this shape wears well. Stubble is the zero-risk option and keeps the jaw's own line visible, and clean-shaven is equally safe. Fights your shape: sides grown out and flared, a long beard brushed wide and cut square across the bottom, and the chin strap, which does nothing but draw an outline around your widest feature. Whatever you choose, the maintenance rule is the same: the sides get trimmed more often than the chin, because the sides are where this shape cannot spend width.
Collars: build the frame above the jaw
The collar is the frame the face sits in, and for this shape it has one job: put width at the top of the torso so the jaw above it is not the widest line in the whole picture. The spread collar is the shape's best friend for exactly that reason, opening the shirt's frame wide at the neck and balancing the jaw above it. The semi-spread is the everyday version of the same idea, and between the two of them most shirt buying is settled. The collar column in practice is the Oxford shirt, and our Oxford ranking scores the shirts themselves; this page's contribution is which collar to reach for when you buy one.
With care: a classic point collar with the top button open softens its downward pull, and a band collar removes the question entirely in summer. Fights your shape: the narrow point collar, especially buttoned to the top, which draws two straight lines down from the neck and delivers the eye directly to your widest feature. Knitwear follows the same logic one layer up: shawl collars and open cardigans build width across the shoulders and upper chest, widening the frame from below in the right direction, while a high, tight crew neck leaves the jaw as the only event at the top of the outfit.
The five mistakes triangle faces make
1. Skin-tight sides. The most common one, usually ordered as a tidy-up. Tight sides remove the upper face's only counterweight and leave the jaw unopposed. Gradual is tidy enough. 2. Frames narrower than the forehead. A frame that sits inside your narrowest line advertises it. The frame should be at least forehead width, with its weight on top. 3. Growing the beard out wide. Length at the chin can help; width at the jaw corners never does. Trim the sides twice as often as the chin. 4. Narrow collars buttoned to the top. Two straight lines pointing at your widest feature. Open the collar, widen the spread, or change the shirt. 5. Self-diagnosing from a selfie. A front camera at arm's length stretches the centre of the face and shrinks the edges, which can manufacture a triangle reading on a square face or hide one on yours. Three tape measurements on the hub settle it in two minutes.
The Triangle Rule
Width on top, quiet at the jaw. Every decision on this page is that sentence applied four times: hair, frames, beard, collar. Your jaw is a feature, not a flaw, and nothing here tries to hide it. The styling simply stops underlining it twice.
FAQ
What is a triangle face shape?
A face whose jawline is its widest line and whose forehead is its narrowest, widening as it descends. In the Decoder measurements, it is the one shape where the jaw width out-measures the forehead width. Some guides call the same outline pear; the guidance is identical under either name.
Is a triangle face the same as a pear face?
Yes. Triangle and pear describe the same outline: narrow forehead, wider jaw. Barbering and eyewear fitting practice use triangle more often, which is why this system files it that way. Nothing about the haircut, frame or beard guidance changes with the name.
What haircut is best for a triangle face shape?
One that puts volume and texture on top and keeps the sides tapered gradually rather than shaved tight. A textured crop with height is the reliable default, and a side part with body is the office version. The top should end up looking wider than the jaw, not narrower.
What glasses suit a triangle face shape?
Top-accented frames, including browlines, with a strong top bar and a width at least equal to your forehead. The frame should put its visual weight on the top line of the face, where a triangle carries the least. Avoid bottom-heavy frames and frames narrower than your forehead.
Should a triangle face shape grow a beard?
Yes, kept short and close along the jaw sides. A beard draws on the jawline, which is already this shape's widest line, so bulk at the jaw corners doubles the emphasis. Keep any extra length at the chin point, where it adds a little length instead of width. Stubble and clean-shaven are both safe.
Is my face triangle or square?
Measure your forehead width and your jawline width. If the two are close to equal and the angles are strong, it is square. If the jaw is clearly the wider of the two, it is triangle. The collar and haircut answers differ between the two, so the tape is worth the two minutes.

This page is Spoke No. 01 of the Face-Shape Decoder, and the Decoder hub is its front door: the full measurement method, the other six shapes, and the complete decision matrix live there, and the per-shape series continues from it shape by shape. Its sibling spokes solve the neighbouring problems, one per shape: the oblong page, where length does the talking (the widths sit in a similar range and the face runs to about 1.6 times its width or beyond), the square page, where the forehead and jaw measure close to equal in straight lines (a jaw clearly wider than the forehead is yours, here), the diamond page, where the cheekbones are the widest line and the jaw narrows below them rather than leading, the round page, where length and width run close with no line widest and every line curved, the oval page, where the curves stretch to about one and a half times the width and nothing dominates, and the heart page, this shape's inverted pair (their forehead is the widest line, their face narrows as it descends, and their answers take emphasis off the top where yours add it). If you landed here between shapes, the hub's matrix is the tiebreaker. Sizing is the other half of fit: our Shoe Size Conversion Chart is Decoder Utility No. 01 and ends the other guessing game. And for the collar column in practice, the shirts it applies to are scored in our Oxford shirt ranking, with the cloth behind them explained in what is an Oxford shirt?
