Upload a straight-on photo and get your canthal tilt in degrees for each eye. Positive means the outer corner sits higher than the inner one. Most adults measure a slight positive tilt, roughly +4° to +8°.

What your number means
The 1–10 score peaks at 5° to 8.5° for men and 6° to 9.5° for women. Tilt beyond the range doesn't score higher: a very steep tilt reads as less natural, not more attractive.

What it means
Negative
below 0°
The outer corner sits lower than the inner corner.
Neutral
0° to 4°
Close to flat. Common, and not a flaw on its own.
Positive
4° and above
The outer corner sits higher. The most common result in adults.
Photo tips
Get a photo that measures true
Camera angle changes canthal tilt more than anything else. Tip your chin down a few degrees and the outer corners look higher.
01Hold the camera at eye level, about an arm's length away. Avoid wide-angle selfies held close.
02Look straight into the lens with your chin level, not raised or tucked.
03Keep a relaxed, neutral face. Smiling and squinting lift the outer corners.
04Take off glasses and use even, front-on light so the corners are easy to see.
Method
How the calculator measures it
It uses the same engine as the Face Analyzer, so both always give you the same number for the same photo.
01It maps 478 points on your face, then rebuilds each eye corner where the upper and lower lid lines meet. Raw corner points sit slightly high and add about 2° of tilt if used as they are.
02It measures each eye against the line through the centres of both eyes, not against the edge of the photo, so a tilted head or camera doesn't change the answer.
03Both eyes are measured on their own and then averaged. If they disagree by more than 2°, the photo is usually slightly turned.
04You can drag any corner. A corner you move is used exactly where you put it.
Can it change?
What can and can't change your tilt
Tilt is set mostly by the shape of the eye socket and the tendon that anchors the outer eyelid, so exercises, mewing and taping don't change the angle. Sleep, less puffiness and groomed brows change how the eye area looks; they don't change the angle. Surgery (canthoplasty) is the only thing that changes the angle itself, and it carries real risks.
A slight positive tilt, roughly +4° to +8°, is typical and reads as natural. In this calculator the score peaks at 5° to 8.5° for men and 6° to 9.5° for women. More tilt is not automatically better.
How do I measure my canthal tilt?
Draw a line from the inner corner of each eye to the outer corner, and measure its angle against the line through both eyes. This calculator does that from a photo: upload a straight-on, eye-level picture and adjust the corners if any dot is off.
Is a negative canthal tilt bad?
It's less common, but a single angle doesn't decide how attractive eyes look. Eyelid exposure, brow position, under-eye area and skin matter as much. Check your photo first, because a raised chin alone can make a neutral tilt read negative.
Why do my two eyes give different numbers?
Small differences of 1° to 2° are normal. Larger gaps usually mean the head was slightly turned or a corner dot sits a few pixels off. Retake the photo straight on or drag the dots to the exact corners.
Is my photo uploaded?
No. The face model runs in your browser, and the photo never leaves your device.
Note:This is a measurement from one photo, not a medical assessment. Lens distortion, head position and expression all move the result by a few degrees.
