Oblong Face Shape Hairstyles

Measure first, then read the notes. Oblong face shape hairstyles, or the search for the best hairstyles for an oblong face, are the same question: which of the three ratios is the hair question really about? Put your numbers in and check they belong to this row at all. No measurements yet? The detector reads the four distances from one photo and scores all seven rows together.

The placeholders are the oblong targets in the published file: 0.30 allowed on the length target, 0.12 on each width target.

The row Oblong in face-shape-ratios.csv, published on the data page under CC BY 4.0 with a DOI. This site has no separate oblong shape page yet, so the three numbers above are the whole of what this data says about the shape.

What each hair question is really about

Geometry, not a style guide. Each question below belongs to one of the three ratios, and the ratio is named. It is this data set's own reading of its own numbers — not a standard from elsewhere.

No cut names, no styling steps and no promises about how a style will look. The file holds ratios rather than instructions, and nothing here is invented to fill that space.

Measure before deciding

Tape flat against the skin, square to a mirror an arm's length back; write numbers, not impressions. Each distance has a row in the printable tape-measure worksheet (PDF), and the method is on how to know what face shape you have. Both end at the same published file.

What it costs to use this page

No charge, no account, no upgrade tier, and no daily limit or cap on how many photos and measurements you run through the site — no counter exists anywhere. The ratios are public, so there is nothing a sign-in would open up.

Where the photo and your numbers stay

One page of JavaScript plus a model file: the model arrives once, then all of the measuring happens inside your browser tab, so the photo is never uploaded anywhere and no server of ours receives it. The box above compares your ratios in the page and sends them nowhere.

Oblong beside the rows it gets confused with

ProfileLength ÷ cheekboneForehead ÷ cheekboneJaw ÷ cheekboneAgainst oblong, from these two rows only
Oval1.450.860.760.30 shorter, jaw 0.08 narrower
Diamond1.500.740.72Forehead 0.14 narrower, jaw 0.12 narrower
Round1.180.900.860.57 shorter, both widths within 0.02
Square1.220.970.950.53 shorter, jaw 0.11 wider

Every figure in the last column is arithmetic on the two rows it names. Sorting the length column of the file puts oblong at one end: 1.75 is the highest face-length ratio of the seven, with the next row down at 1.50 and the lowest at 1.18. Length is what this row is about.

Oblong hair questions

Is the length ratio the one that matters most on this row?

By the file, yes: 1.75 is the highest of the seven, 0.25 above the next row. The two width ratios sit in the middle of their columns.

How do I tell oblong from oval with a tape measure?

The length ratio: 1.75 against 1.45 is 0.30 apart, exactly the length tolerance, so a face can land inside both rows. The width columns differ by no more than 0.08.

Which neighbour is closest to oblong on the widths?

Round: 0.90 and 0.86 against oblong's 0.88 and 0.84 — within 0.02 on both, while the length differs by 0.57.
