Posture & Body-Structure Self-Assessment
An educational self-assessment — not medical advice, and not a diagnosis.
This tool helps you see how your body lines up in a photo, so you know what to look for and what to ask about. It doesn't identify a single cause, and it isn't a substitute for professional care.
Your photo never leaves your device — all processing happens right here in your browser. No image or coordinate data is ever transmitted or stored.
Ear position is used only as a posture reference point, never for identification.

Step 1 — Take a side-view photo
Stand sideways to the camera in a relaxed, natural stance. Line up with the guide.
For clearer landmark detection, wear fitted clothing and stand against a plain background.
Stand naturally and rest your palms flat against the sides of your thighs — this keeps your arms from covering your shoulder, hip, and knee landmarks.
Step 2 — Review
These lines were drawn automatically from your photo. If the photo looks off, go back and retake it — nothing here needs manual placement.
Tip: if a teal dot looks off, drag it into place. Tap a reference line to select it (✕ to delete).
We couldn't find a clear body shape in this photo. Please try again with a full-body side photo, standing a few steps back so your head and feet are both visible.

Self-check: the "groove line"
From the front, a well-aligned body shows one continuous groove running from the front of the neck down to the lower abdomen. From the back, one continuous groove runs from just below the skull down to the crease of the glutes. Next time you're in front of a mirror, take a look — is the line continuous, or does it break somewhere?
This is an educational observation, not a medical diagnosis. Posture is shaped by many factors — this assessment does not identify a single cause.
Add another angle
Front and back views are optional — add either one whenever you're ready.
