Your Face Shape: Triangle

Your Triangle Result: FAQ

What does the confidence figure on a triangle result mean here?

It reports how far your five measurements sit from the triangle row of the published prototype table, judged against how far apart the seven rows are from each other. It is a distance, not a probability, and not an accuracy claim — this site publishes none. On a triangle result the figure needs more context than on any other shape, because the row it measures against is the least settled of the seven. No photograph in our reference set carried this label, so the row was interpolated from the published ordering rather than fitted to a measured group mean. The figure is computed exactly as it is for the other six shapes; what differs is how much the row underneath it rests on measurement. The triangle guide and /about both say this openly.

Where does the range beside my triangle measurements come from?

That column is the triangle row of the prototype table, plus or minus one standard deviation, converted onto the tape-measure scale so it can sit beside your own numbers honestly. Read the jaw row first: this is the only row in the table where the jaw clearly measures wider than the forehead, and that gradient is the entire shape. The forehead row matters for the same reason in reverse. Now the caveat, which belongs beside this column rather than in a footnote. No photograph in our reference set carried the triangle label, so the centre of this range was interpolated from the published ordering of the seven shapes rather than fitted to a measured group mean. It is the only one of the seven rows of which that is true, and a real measurement campaign could pull it inward.

Should I read the bars or the boundary callout on a triangle result?

Each bar is the same distance measure as the headline figure, drawn against one shape, so you can see whether triangle won cleanly or only just. They are not a ranking of faces and not the share of people with each shape; this site publishes no prevalence figure for any of the seven. On a triangle result read the bars with one discrepancy in mind. Oval is the shape sitting nearest to triangle in the published table, but the rule set names square as the boundary, because square is the pair the site has a written explanation for and the jaw width decides it. The triangle guide states this rather than letting the callout above imply the two agree. Both comparisons are worth reading, and they ask different questions of your measurements.

My result says triangle with no second shape named. How far should I take that?

Further than a coin toss and not as far as a fitted row would warrant. No second shape means the runner-up was not close enough to flag, not that the measurement was exact — and here there is a second layer, because the row itself was interpolated from the published ordering rather than fitted to measured group means. No photograph in our reference set carried the triangle label. That does not make the result meaningless: your five measurements are your own, they are printed above, and the jaw-against-forehead gradient they describe is a real thing about your face that no prototype table conferred on it. It does mean the tape-measure path is the better route to this particular label, since it asks you about widths you can check directly.

Which of the two paths is the better route to a triangle label?

On this shape, the tape-measure path — which is not the answer the site gives for every shape, and the reason is worth stating. The two rows that the rule set treats as triangle's nearest boundary pull apart on the jaw width read against the cheekbone width — one of the five readings the classifier scores at once. Both are widths you can measure directly with a tape, and both are measured the same way on either path, so the calculator loses nothing here. It does lose the chin taper, which it cannot measure at all — but on triangle the chin taper is not what decides the boundary. If the path that disagreed said oval, note that oval is the shape nearest to triangle in the published table, so that disagreement is less surprising than it looks.

Should I buy glasses or get a haircut based on a triangle result?

Yes, and this is the one shape where the advice holds more firmly than the label does. The picks below come from a styling convention about a gradient — a face that widens downward from a narrow forehead — and that description of your face is something you can check in a mirror without any classifier. What is less settled is the boundary of the category: the triangle row was interpolated rather than fitted, since no photograph in our reference set carried the label. So take the picks, and read the square picks beside them, because square is the named boundary and the jaw width decides which side of it you are on. Nothing is being sold to you, and the styling convention is not a claim about your face's worth.
