Start with the average
The average summarizes the visible eye-corner tilt across both eyes in this photo.
Canthal tilt test
Measure your eye-corner angle.
Canthal tilt is the angle formed between the inner and outer corners of the eye. Upload one clear, front-facing photo to measure it in degrees.

Tích cực
Cả hai khóe mắt bên ngoài đều nằm phía trên góc trong trong bức ảnh này.
"Dương" và "âm" chỉ mô tả hướng góc chứ không mô tả kết quả tốt hay xấu.
Các góc được đo tương ứng với hình ảnh nằm ngang. Hiệu chỉnh cuộn đầu được áp dụng khi đường mắt bị nghiêng.

Độ nghiêng Canthal đo góc giữa góc trong và góc ngoài của mỗi mắt. Đây là phép đo hình học, không phải là điểm hấp dẫn.
How it's measured
How the angle is measured.
A horizontal reference line is compared with the line from inner to outer canthus. Positive tilt means the outer corner sits higher than the inner corner.
Angles are measured relative to the image horizontal after basic head-roll correction.

How to read it
Compare left and right
A small difference between sides is common. Use the difference row to see how closely both eyes agree.
Use the classification as a label
Positive, neutral, and negative describe the direction of the angle, not whether it is good or bad.

FAQ
Canthal tilt questions
What is canthal tilt?
Canthal tilt is the angle formed between the inner and outer corners of the eye. This tool measures that angle in a photo.
How is canthal tilt measured?
The tool detects inner and outer eye-corner landmarks, applies basic head-roll correction, and measures each angle relative to the image horizontal.
What does positive canthal tilt mean?
Positive tilt means the outer eye corner sits higher than the inner corner in this photo. It describes direction, not quality.
What does negative canthal tilt mean?
Negative tilt means the outer eye corner sits lower than the inner corner in this photo. It describes direction, not quality.
Is one canthal tilt better than another?
No single canthal tilt is universally "best." This tool describes visible eye-corner geometry in a photo. Perceived attractiveness depends on many facial and photographic factors.
Why are my left and right eye angles different?
Small differences are normal. Pose, head tilt, expression, and lighting can make one eye appear more upturned or downturned than the other in a single photo.
Can head tilt or camera angle change the result?
Yes. This tool applies basic roll correction, but large head tilt, side angles, squinting, or partial eye occlusion can still change the reading.
What photo works best?
Use a clear, front-facing photo with both eyes fully visible, even lighting, minimal head tilt, and a neutral expression.
Is this a medical measurement?
No. This is a geometry reading for one photo. It is not a medical diagnosis or clinical measurement.
Is my photo private?
Yes. Analysis runs locally in your browser. Your photo is not uploaded for this canthal tilt test.
