Measuring to predict, not to judge
A proportion is a ratio between two measurements: forehead width against cheekbone width, the height of the middle third against the lower third, face length against maximum width. On their own they say nothing aesthetic. They become useful when they answer an operational question: if I shorten here, where does the eye go?
That's why in a consultation proportions should be read in pairs and never in isolation. A long face with a narrow jaw and a long face with a wide jaw share the same height-to-width ratio but react in opposite ways to a bob: in the first case the cut closes and fills, in the second it widens the point that was already fullest.
The practical benefit is repeatability. An experienced professional makes this reading by eye in seconds but can't explain it; a less experienced one doesn't make it at all. Making proportions explicit lets the whole team arrive at the same proposal and, above all, justify it to the client in the same words.
How perception changes when technique becomes visible
Consultation becomes stronger when every aesthetic choice has a motivation that is simple to explain. The chart is qualitative: it shows the levers the salon can strengthen by transforming technical reasoning into visual experience.
From measurement to technical choice
The table turns four ratios into operational consequences: what happens to volume, where the shortest point belongs and what effect to expect.
| Observed proportion | Effect to avoid | Technical direction |
|---|---|---|
| Face longer than wide | Flat lengths that lengthen further | Volume at cheekbone width, shortest point above the jaw |
| Forehead wider than cheekbones | Sharp centre part that widens the top | Soft side part, strands covering the forehead corner |
| Dominant lower third | Lengths ending on the jaw | Length below the collarbone or a clean bob above the jaw |
| Very high hairline | Hair pulled straight back | Long open fringe or front strands that shorten the vertical |

How to use it with the client in the chair
- Show two measurements, not eight: the consultation has to stay readable.
- Tie each measurement to a visible consequence, never to a judgement.
- Record the proportions in the client record: next time they save you starting over.
The temptation, once you have an analysis tool, is to show everything it returns. That's the most common mistake: the client feels measured, not advised. Two well-chosen proportions, said out loud while you both look at the screen, are worth more than a complete report handed over in silence.
The other use, less visible but just as valuable, is internal. When proportions end up in the client record, the colleague who performs the service next time knows why that length was chosen, and the salon stops depending on one person's memory.

Frequently asked questions
Do you need special tools to measure proportions?
No. A well-aligned front photo is enough for the ratios that matter in a consultation. Saloria calculates them on the temporary photo, which isn't kept beyond the session.
Do proportions change over time?
Very slowly in the bone structure, faster in the tissues and the hairline. So it's worth redoing the reading after a year or after a significant change, not at every visit.
How do you explain a proportion without offending?
By talking about effect, not flaw: «this length moves the eye here» works, «your face is too wide» doesn't. Vocabulary is part of the method, not a detail.
