Your Face Shape: Square

Your Square Result: FAQ

What is the confidence figure on this square result measuring?

The distance from your five measurements to the square row of the published prototype table, judged against how far apart the seven rows sit from each other. It is not a probability and not an accuracy claim; the site publishes no accuracy figure anywhere, and /about explains why. Square is worth a word of its own here, because its two near boundaries rest on different readings. Triangle is the nearest in the rule set, and the width line behind that comparison is the jaw against the cheekbone, while round sits almost exactly as close behind and the reading there is the corner at the jaw — the weakest of the five on this site's own photographs. A square result with a modest confidence figure is usually near one of those two, and the bars below tell you which. A square result with a modest confidence figure is usually near one of those two, and the bars below tell you which.

What should the range beside my forehead and jaw widths tell me?

That column is the square 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. Its purpose is to show you which feature decided the result. On a square result the forehead and jaw rows are the ones to read together: this is the row where the three widths run closest to level, so a forehead width and a jaw width that sit at the same place in their ranges is what square looks like from the inside. The spread beside every row is the same width on all seven result pages, since it comes from one per-feature figure rather than one fitted per shape. The square row was fitted to measured group means from our reference set.

Do the bars tell me whether triangle or round ran second on a square result?

Each bar is the same distance measure as the headline figure, drawn against one shape, so you can see whether square won cleanly or only just. They are not a ranking of faces, and they are not the share of people who have each shape — this site publishes no prevalence figure for any of the seven, because the numbers in circulation have no stated sample and no stated method. On a square result read two of them. Triangle is the nearest boundary in the rule set, and what separates the two is whether the jaw measures wider than the cheekbones above it. Round sits almost as close behind, and there the deciding feature is the corner of the jaw instead. Which bar is higher tells you which of the two questions your face is actually near.

My result says square with no second shape named. Does that mean it is settled?

No. A second shape is named only when the runner-up is close enough to the winner to be worth flagging, and the absence of one means the gap was too wide to flag — not that the measurement was exact. Square is a case where that distinction matters more than usual, because the row sits with two near neighbours decided by different features, and a face can be unambiguous against one while sitting close to the other. The confidence figure measures distance to the prototype rather than margin over the runner-up, so it can read modestly even on a clean single-shape result. The seven bars are where the runner-up shows itself, whether or not it was close enough to be named.

Two paths gave me two different answers and one of them was square. What now?

Read the disagreement callout near the top of the page first, because it names the feature the two paths differ on rather than leaving you to guess. Which feature that turns out to be matters here. If the other path said round, the reading the two paths differ on is the corner at the jaw, and the photo path is the one that measures it — the calculator estimates it from your four widths and lowers its confidence ceiling to say so. If the other path said triangle, the jaw width against the cheekbone width is what separated you, and both paths measure that, so re-measure with the tape level and your jaw relaxed rather than clenched. The square guide and the guide for whichever shape disagreed both carry the comparison.

Should I act on a square result when buying glasses or choosing a haircut?

Use it as a starting point and read one neighbouring set of picks beside it. The recommendations below are a styling convention applied to a measurement, and a square result has two boundaries worth knowing about rather than one, so the picks that will hold up best are the ones square shares with its neighbour. Which neighbour to read depends on the bars: if triangle ran second, the question is whether your jaw measures wider than your cheekbones; if round ran second, it is how sharp the corner of your jaw is. Both are cheap to check with the tape-measure path. And no brand is being recommended to you — the site sells nothing, which is stated above the picks rather than buried in a footer.
