Face Shape Detector: Find Your Shape, Then Test What Actually Fits

A face shape detector can identify your likely outline, but it cannot tell you whether a frame will slide, pinch, feel front-heavy, or work with your everyday hairstyle. Use the result to narrow your choices. Then test fit, measurements, and comfort before you buy.

Private browser-only tool

Face Shape Detector

Choose a straight-on photo containing only one clearly visible face. This tool measures its face landmarks in your browser and shows the four image measurements it used. If it detects no face or more than one face, it asks for another photo instead of returning a result.

How this tool labels a result

There are no validated universal ratio bands for face shape, so this tool does not invent numeric cut-offs. It compares the four displayed image measurements: when exactly one of forehead, cheekbone, and jaw is widest and exceeds face length, it suggests a heart, diamond, or triangle profile; when face length is strictly larger than every width, it reports a long profile. Otherwise, ties between the largest widths, or between face length and the largest width, report a balanced, uncertain profile. Round versus square, and oval versus oblong, cannot be reliably separated from these four widths alone and are shown as uncertain rather than guessed.

Photos are not uploaded. The browser downloads the landmark model, then reads your selected image locally. No image file is sent to this site.

Start With the Face Shape

Pull hair away from your forehead and jaw. Use a straight-on photo with level eyes and even light. Compare forehead width, cheekbone width, jaw width, and face length.

If two labels seem close, keep both. The next step is more useful than arguing over a borderline result.

For the tape method in full — what is my face shape answered with four measurements, every guide's own ratio bands side by side with their disagreements carried rather than averaged, both disputed jaw-measurement methods, the hairline-versus-mid-forehead baseline gap, centimetre-inch conversions with the arithmetic shown, and a four-line measurement sheet you can download as CSV — read what is my face shape: the four measurements and every guide's stated ratios.

Two of those outlines also have a measurement page of their own: which of the four readings decides a round face shape, and which of the three widths leads on a triangle face — each one carries its table row by row and names the single reading that settles the label.

For a golden-ratio-face score, use the golden ratio face measurement comparison to check which landmarks, photo window, and score fields six public tools actually disclose before treating two percentages as comparable.

For a face analyzer result, use the face analyzer output comparison to separate measurement, label, score, and recommendation before comparing two numeric results.

For a proportion result, use the midface ratio comparison to keep the numerator, denominator, endpoints, and capture method attached to the number before comparing two results.

Use Frame Size Before Frame Stereotypes

Round faces are often steered toward angular frames, while square faces are often steered toward round or oval frames. That can be a useful visual shortcut. It is not a fit test.

For a round-face-specific size chart with real frame measurements pulled from brand product pages, see the glasses for round face size guide. For an oval-face-specific size chart, see the glasses for oval face size guide. For a square-face-specific size chart, see the glasses for square face size guide. For a heart-face-specific size chart, see the glasses for heart shaped face size guide. New comparison guides cover glasses for diamond face shape, glasses for oblong face, sunglasses for oval face, sunglasses for square face, and sunglasses for heart shaped face. For a round-face sunglasses size chart, see the sunglasses for round face size guide.

Check the three numbers printed inside a frame arm. For example, 53-16-148 means a 53 mm lens width, 16 mm bridge width, and 148 mm temple length. The numbers describe frame geometry; they do not promise comfort.

A practical optical-centre screening formula is:

(lens width + bridge width − pupillary distance) ÷ 2

A result near 0 is treated as the best match in this rule of thumb. A result below 3 is commonly treated as ideal, 3–5 as workable, and above 5 as a reason to reject the frame. This is a shopping heuristic, not a substitute for an optician’s fitting. For what the pupillary distance term costs when it is wrong, see pupillary distance at the lens.

Specific Try-On Notes Worth Using

Check Width, Bridge, and Pressure

One visual-shopping rule says the total frame width should stay close to cheekbone width, within roughly ±3 mm. It is not a medical standard. It is simply a way to avoid a frame that overwhelms the face or feels visibly too narrow.

The bridge deserves its own test. High cheekbones, a low bridge, or fuller cheeks may make adjustable nose pads more important than the frame shape itself. Keep the frame on for at least ten minutes. Look down, turn your head, smile, and check whether it slides or leaves pressure marks.

If the frame shifts after lenses are installed, the problem may be lens weight or bridge fit, not your face shape.

Hair Can Override the Detector

Hair changes the visible outline. A blunt fringe can shorten a small forehead. Hair across the cheeks can make the middle of the face look wider. Crown volume can lengthen the face, while width near the jaw can balance a narrow lower face.

For round faces, long layers, side movement, or curtain pieces may create a longer visual line. For oblong faces, width at the sides or a fringe may reduce the feeling of excess length. But natural curl, cowlicks, hair density, maintenance time, and the usual part should decide whether the style is realistic.

For a diamond-shaped face, use a barber-ready haircut brief that tests side width, fringe length, and hair behaviour before you commit to a cut.

If your face is longer than it is wide, read the oblong-face haircut brief for placement-based instructions you can use in a salon consultation.

Layered Haircut and Fringe Guides

Choose a layer plan by texture, length, density, or maintenance: curly hair, wavy hair, straight hair, long hair, medium length, or a short layered haircut.

For a narrower decision, use face framing layers, layered haircuts for men, the at-home layering guide, bangs for thin hair, or a layered bob for thin hair.

Bob, Fringe, Pixie, Shag, and Wolf Cut Guides

Compare the wolf cut, butterfly haircut, and shag haircut by density, texture, and daily styling.

For a bob, use the layered bob, lob haircut, inverted bob, A-line bob, or bob for thin hair guide. For the front, compare curtain bangs, side bangs, and a pixie cut for thin hair.

Men's Short Hair and Barber Guides

Compare the height and edge handling in a taper fade with the full side blend in a fade haircut. For shorter top lengths, use the buzz cut and crew cut decision guides.

For shape on top or at the back, see the pompadour, quiff, undercut, and mullet pages.

To set the two numbers a short cut actually changes, start with the short hairstyles for men guard and top-length chart.

If the front of the line has moved back, the millimetres it has travelled decide the cut — see the receding hairline haircuts for men fringe-length table.

Men's Medium and Long Hair Guides

For length on top, compare the man bun length threshold with the long hairstyles trim interval, and set the band below it with the medium length hairstyles for men chart. For shaped tops, see the slick back, comb over, and middle part.

For a short forward top, use the French crop and textured crop guide. For texture-specific care, see curly hair.

Men's Fade, Hawk, and Short-Cut Guides

For the fade family, compare the low fade, burst fade, and the core fade haircut. For height on top, see the mohawk haircut, the mohawk fade, and the faux hawk.

For the short textured top, see the Edgar cut, bowl cut, and side part. For mid-length movement, see the bro flow.

Men's Haircuts and Fades

Start at the haircuts for men index if you have not picked a family yet. For fade heights, compare the low fade, high fade, drop fade, burst fade, skin fade, and the core fade haircut.

For length on top, see the two block haircut, buzz cut fade, curly hair fade, and wolf cut for men.

Final Decision

Take straight-on photos in the same lighting with two frame shapes or two hairstyle directions. Compare them after a few minutes, not only in the mirror.

Colour readings work the same way: before you treat two seasonal color results as a disagreement, compare the test conditions and the decision rule behind each one — see which conditions to compare before two seasonal color results count as a disagreement.

A face shape detector gives you a first hypothesis. Frame size, bridge fit, lens weight, hair behaviour, and comfort decide whether the result is useful.

For a brow-placement guide that keeps a fringe light and adjustable, read bangs for a heart-shaped face.

For a men’s cut brief with measured top length, fringe placement, and a softer side transition, read the heart-shaped-face haircut guide for men.

For an oval face, choose your haircut by density and styling time with this barber-ready oval-face guide for men.

For a square face, compare three measured short-cut briefs in this square-face haircut guide before asking for a skin-tight fade.

For short styles that keep side bulk controlled, see the round-face haircut guide for men before choosing a fade height.

For women comparing bob variations — length band, face-framing start point, and fringe — see the bob haircut for round face comparison chart.

For women deciding how much density to remove, where the first face-framing piece should land, and whether the cut will survive an ordinary wash day, use the layered haircut for round face guide.

For fine or low-density hair, use the layered haircut for thin hair guide to preview the perimeter before removing weight.

For women considering the in-between length, use the long bob for round face guide to test the dry perimeter, pull-back length, humidity, layers, and daily styling routine.

For men comparing beard styles for a round face — length band, mustache and beard line placement, and the sideburn or neckline pairing — see the beard styles for round face comparison chart.

For women going shorter — crown height, side taper, layering start point, and the fringe-and-sideburn pairing across eight pixie variations — see the pixie cut for round face comparison chart.

For an oval face, compare a pixie cut for oval face or a bob haircut for oval face by front shape, perimeter, texture, and the source statement behind each row.

For a square face, compare a pixie cut for square face or a bob haircut for square face with conflicting edge and fringe advice left visible.

For women who want to keep their length while deciding where the first movement should meet a strong jaw, use the layered haircut for square face guide.

For fullness rather than outline — what each cut does for chubby cheeks and a softer under-chin, its length band, layer start, and fringe pairing across nine styles, with the guides' two live disputes shown side by side — see the haircut for chubby face comparison chart.

For men with the same fullness — fade height, side and nape handling, top length, and the fringe or beard pairing across eleven cuts, with the guides' live disputes on buzz cuts and slick backs shown side by side — see the hairstyle for chubby face male comparison chart.

For length rather than shape — every tier from buzz cut to classic, the inches and centimetres each top guide actually states, the grow-out months between rungs, and where the charts disagree — see the hair length chart.

If your jaw is wider than your forehead, use this triangle-face haircut guide to place texture at the crown and temples rather than beside the jaw.

Compare fringe landing points and source disagreements for square, diamond, oblong, and triangle face shapes.
