What is canthal tilt?
The canthal tilt is the angle of the line connecting the medial canthus (inner eye corner) and the lateral canthus (outer eye corner), measured against the horizontal. A positive tilt means the outer corner sits higher than the inner corner. Cephalometric reference data places the typical attractive range at roughly +2° to +8°.
How this tool measures it
We run Google MediaPipe's 478-point face landmarker directly in your browser, take the inner and outer corner landmarks of each eye, compute the angle per eye with plain trigonometry, and average the two. No AI model guesses the number — it is pure geometry on detected landmarks.
How accurate is it?
Landmark detection on a clear, front-facing, level photo is typically within a fraction of a degree of manual annotation. Head roll is the main error source — keep your eyes level with the camera. The result is an approximation for orientation, not a clinical measurement.
