# Face Shape Haircut AI — LLM Reference

Last updated: 2026-11-04

## Overview
Face Shape Haircut AI measures your face shape from one selfie and shows the haircuts that suit it on your own photo. The face shape and three previews are free with no sign-up; every haircut with a barber card is a one-time $9.99–$29.99. Operated by Jacob Logic Technology LLC (Wyoming, US).

## How it works
1. Upload or take one front-facing selfie in the browser. No app, no account.
2. 478 facial landmarks are found and four ratios are measured: face length ÷ width, forehead ÷ cheekbones, jaw ÷ cheekbones, and jaw angle.
3. The ratios are compared with seven face shapes (oval, round, square, heart, diamond, oblong, triangle). You get the closest shape, the four numbers, and a "leaning" shape when two are close.
4. Haircuts are picked for your face shape, hair type and hairline and rendered on your own photo with AI, keeping your hair color and hairline. Three previews are free.
5. After a one-time payment, every cut comes with a barber card: the photo, your face shape and the cut broken down for the barber: length on top, clipper guard and fade height on the sides, the back, texture (layering / point-cutting), how to style it with what kind of product, how many weeks between trims, and how many months to grow out when the cut is longer than your hair now.
6. On the results page you can put 2–4 cuts side by side with your current photo before you pick one.

## How face shape is measured
- Face length ÷ width: forehead top to chin (×1.12, because the top landmark sits below the hairline), divided by cheekbone width.
- Forehead ÷ cheek: temple width divided by cheekbone width.
- Jaw ÷ cheek: jaw-corner width divided by cheekbone width.
- Jaw angle: the angle at the jaw corner between cheekbone and chin; smaller is squarer.
The four ratios are compared with seven face shapes; the closest is the result and a second shape is reported as "leaning" when it is nearly as close. Typical values below come from the same model.

## The 7 face shapes
### Oval
- Looks like: A little longer than wide; cheekbones slightly wider than the forehead; jaw tapers to a soft rounded chin.
- Typical ratios: length ÷ width 1.38, forehead ÷ cheek 0.87, jaw ÷ cheek 0.80, jaw angle 136°
- Haircuts that suit it: Almost anything — curtain bangs, long layers, short crops.
- Avoid: Heavy fringe that hides the face’s balance.

### Oblong
- Looks like: Noticeably longer than wide; forehead, cheekbones and jaw about the same width.
- Typical ratios: length ÷ width 1.50, forehead ÷ cheek 0.87, jaw ÷ cheek 0.80, jaw angle 136°
- Haircuts that suit it: Width at the sides, bangs, cuts that stop adding height.
- Avoid: Tall quiffs and long, flat, straight hair.

## Frequently asked questions
**How do you work out my face shape?**
We place 478 points on your face and measure four things: face length against width, forehead width, jaw width (both against your cheekbones) and the angle at your jaw. Those numbers are compared with seven face shapes — oval, oblong, round, square, heart, diamond and triangle. If you sit between two, we say so (for example "Oval, leaning Oblong").

**Is the face shape result really free?**
Yes. You see your face shape, the four measurements and three haircut previews (one clear, two blurred) without paying or signing up.

**What makes a good selfie?**
Face the camera at eye level, in even light, with your hair off your forehead and no hat, hood, headphones or hand near your head. If something is in the way we tell you before anything else happens, and that try doesn't count.

**Will the haircut look exactly like this?**
The images are AI previews made from your own photo. We keep your hair color and hairline and never add hair where your scalp shows, but the real result depends on your hair and your barber. That's why every cut comes with a barber card that says exactly what to ask for.

**What happens to my photo?**
It is stored privately and used only to make your results. It is never used to train AI models and never shared. Before paying, you can delete your photo and previews anytime with "Delete my photo now"; otherwise unpaid photos are deleted after 30 days. Paid results are kept for one year so you can come back to them.

**What do I show my barber?**
A one-page barber card (PDF) for every cut: the photo of you with that cut, your face shape, and the cut broken down for the barber — length on top, clipper guard and fade height on the sides, the back, texture, how to style it and how often to trim. It also says how many months to grow out when a cut is longer than your hair now. Your barber can read it in about 30 seconds.

**Can I compare haircuts side by side?**
Yes. On your results page, pick 2 to 4 cuts and see them next to your current photo at the same size, then open the barber card for the one you choose.

**Is it a subscription?**
No. You pay once — $9.99, $19.99 or $29.99 — and keep your results page for a year. If you're not happy, email us within 7 days for a full refund.

**I lost my results link.**
Go to "Find my results" and enter the email you used at checkout. We'll send the link again.

## How it differs
- Face shape is measured from facial landmarks and the four ratios are shown, instead of a quiz or a guess. The same photo always gives the same result.
- Haircuts are picked for the measured face shape, hair type and hairline, not from a generic filter list.
- Each cut comes with a barber card that breaks the cut down (top, sides and fade, back, texture, styling, trim interval), so a barber can read it in about 30 seconds.
- You can compare 2–4 cuts side by side with your current photo.
- Runs in the browser with no app or account; one-time payment, no subscription.
- Works only on your own selfie: photos of celebrities or public figures are refused.
