Are facial thirds horizontal or vertical?

The face is split into horizontal bands. You measure the vertical distance between the landmarks that bound each band.

Do facial thirds have to be equal?

The classic rule calls equal thirds balanced. Mixed evidence means you shouldn't treat that rule as a requirement for your face.

Can I measure facial thirds from a selfie?

Yes: hairline to brow, brow to nose base, and nose base to chin. The result describes those distances in the photo, rather than establishing a fixed verdict about your face.

Measure the bands between named landmarks

Each third has a defined start and end. The upper band runs from your hairline to your brow. The middle band runs from your brow to the base of your nose. The lower band runs from your nose base to your chin.

Keep those boundaries consistent when comparing face thirds. If you can't identify a landmark clearly, leave the measurement uncertain rather than guessing. A precise-looking result isn't useful when you don't know where it starts.

Equal thirds are a reference rule

The equal-thirds rule calls matching band lengths balanced. That gives you a reference for comparison, but it doesn't establish how attractive you are. Evidence for that broader judgment is mixed.

Facial thirds describe only these vertical distances. Keep that narrow scope in mind when reading claims about facial harmony. A measurement and a judgment about your whole face answer different questions.

A selfie result belongs to that photo

The common mistake is reading one number from one photo as a fixed fact about your face. Start by checking the marked landmarks. Make sure the result names the same boundaries you intended to compare.

The free face-symmetry scan reads landmark distances from one selfie. It reports left-right differences and basic ratios, and names what it measured. Read those labels before interpreting the result.

Don't use a thirds measurement to draw conclusions about features it didn't measure.

Use the result to answer a specific question

A useful question is whether the marked middle band looks longer than the other bands in your photo. Compare the distances and check their endpoints. That's a clear task with a limited answer.

A less useful step is turning that comparison straight into a list of changes you think you need. A difference from the equal-thirds reference doesn't, by itself, give you a reason to alter your appearance.

For other terms, use the glossary. Check each definition before comparing results that may use different landmarks.
