Hairstyles for Triangle Face Shape
The hairstyles for triangle face shape that work best add width at the temples, soften the sides at the jaw, and land at the chin or lower, rather than ending in a blunt line at the jaw angle.
Start with curtain bangs, a layered lob, or long layers.
A triangle face has the jaw as its widest width, the cheekbone in the middle, and the forehead as its narrowest width.
Triangle also names two different things, and they are judged in different ways. The bone triangle is judged by the four widths below. The hair-end triangle is judged by how many layers there are and where they land, not by a width measurement.
Inverted triangle is the opposite case, with the forehead as its widest width, while the triangle case in this page has the jaw as its widest width. Many readers judge themselves as inverted triangle when the jaw is actually the widest width, and that misjudgment leads to a cut chosen for the opposite balance. The heart face shape page gives the inverted case. "i have an inverted triangle face what haircuts could fit me" — r/HairStyleAdvice, 2026-10-22. Check the four widths first.
How to Measure It Yourself
Measure in this order, using the same unit for all four: forehead width, cheekbone width, jaw width, and face length from the hairline to the chin.
Use J for jaw width, F for forehead width, L for face length, and C for cheekbone width. The intervals are J/C 1.02 to 1.10, F/C 0.80 to 0.98, and L/C 1.00 to 1.55.
For each ratio, the distance is zero inside its interval and the gap to the nearest bound outside it. The decision is the smallest distance, not a requirement that all three pass.

A mixed list like that needs the four-width check first.
Rules You Can Check in the Mirror
Add width at the temples, and keep that width on both sides.
Do not put the added width only at the centre of the crown, because that leaves the sides of the forehead narrow.
Let the sides carry no piled volume at the jaw angle, and let the ends soften below the jaw angle.
Part on one side, with the part line falling above the outer corner of the eyebrow, so the sweep crosses the forehead on a diagonal.
Start the first layer at the cheekbone, not at the jaw angle.
A side-swept fringe suits a triangle face, while a full fringe that covers the forehead makes the narrow forehead read narrower and leaves the jaw as the main line.
Start the sweep at the outer corner of the eyebrow on the parted side, and let the longest end finish above the eyebrow line.
If the sweep drops below the eyebrow line and covers the eyes, move the start higher or shorten the end until it clears the eyebrow line.
Hairstyles for Women
For women, a triangle face hairstyle that works keeps the temple width, softens the jaw, and uses the chin or collarbone landing below.
Curtain bangs: Layers start at the cheekbone and end at the chin landing, so the jaw is not left as a blunt line.
Layered lob: The first layer starts at the cheekbone, the temples keep their width, and the ends land at the chin.
Shag: Layers start at the cheekbone and the ends land at the collarbone, so bulk does not sit at the jaw.
Long layers: Long layers start at the cheekbone, keep temple width, and land at the collarbone rather than at the jaw.
Side-swept fringe: The sweep keeps temple width visible while the ends soften below the jaw and no volume is piled at the jaw.
Pixie: Keep the sides long enough to end below the jaw angle, so the sides fall over the jaw angle with soft ends and no volume piled at the jaw.
Best Haircuts for Triangle Faces for Men
The best haircuts for triangle faces for men follow the same temple, jaw, and landing rules as the women's cuts above, with one change in how the sides are finished.
Crop with a taper: The taper piles no volume at the jaw while the top keeps temple width, and the ends soften below the jaw.
Side part with a taper: The side part keeps temple width while the taper piles no volume at the jaw, and the ends soften below the jaw.
Quiff with a taper: The quiff keeps temple width while the taper piles no volume at the jaw, and the ends soften below the jaw.
Length Lines: Jaw Angle, Chin, and Collarbone
A blunt cut that ends exactly at the jaw angle is high risk on its own. It draws a hard line at the widest width, so if your cut ends there blunt, change the ends or move the landing before you keep it.
The chin is the first shorter landing in this page. A cut that lands at the chin works when its ends are layered and soft, not when they end in a single blunt line.
The collarbone is the longer landing in this page. A cut that lands at the collarbone works when its layers still start at the cheekbone and its temple width is kept, so length alone does not carry the balance.
If a cut passes a landing line without meeting that line's condition, change the cut at that line: soften a blunt jaw-angle end, layer a blunt chin end, or add cheekbone layers to a collarbone length that has none.

That is the moment to decide the landing line before the appointment.
If the Check Points Elsewhere
If your widest width is not the jaw, do not force this page's rules onto a different shape. Hairstyles for heart face shape covers the opposite case, and haircut for my face shape and face shape determination guide cover the general check.
