Can you measure gonial angle from a selfie?

Yes, in a profile or three-quarter view. You need to identify the jaw corner and the edges that meet there.

What does a more open gonial angle mean?

It reads as a softer jaw corner. That's an appearance description, not a diagnosis or a reason to change your face.

Is a photo measurement a fixed fact about my face?

No. Treat the result as a reading from that image, and check the landmarks before relying on the number.

Gonial angle meaning and how to measure it

Where the angle sits

The angle sits where the lower edge of the mandible meets its upright back portion. That upright portion is the ramus. You're looking at the turn between them, rather than the distance across your lower face.

This distinction matters when you compare jaw measurements. An angle describes how the corner turns. A width describes how far apart the corners sit, so the measurements aren't interchangeable.

How to read it from a selfie

A profile or three-quarter view lets you measure the angle at the jaw corner. Choose an image where you can identify the corner and the edges that meet there.

Find the back corner of the jaw.
Follow the lower edge toward the chin.
Follow the upright edge of the ramus.
Read the angle between those directions.

If you can't identify the edges, don't force a precise number. A photo reading describes what you've measured in that image.

What the evidence status tells you

Evidence status: established. Gonial angle is a defined face geometry measurement, rather than a loose label for a sharp-looking jaw.

The description of 120 to 130 degrees as defined isn't a target you need to reach. A more open angle reads softer, but that doesn't make it a fault. Keep the appearance description separate from any judgment about how your face should look. You can check other measurement terms in the glossary.

Which measurement answers your question

Use gonial angle when you want to describe the turn at your jaw corner. Use bigonial width when you want the horizontal distance between the jaw angles.

For a broader shape comparison, the free face-shape finder reads length-to-width and jaw-to-cheekbone ratios on your device and names the closest prototype. Those ratios describe proportions; they aren't the angle at the back of your jaw.
