What is an eye shape detector?
An eye shape detector describes the outline between your eyelids. This eye shape detector keeps three things separate: how tall the opening is for its width, which way the corner line slopes, and whether skin covers the crease. Separating them makes the result easier to check and more useful for makeup or frames.
An eye shape test for opening and width
Each eye's inner-to-outer width is compared with its upper-to-lower lid height. A lower ratio means a rounder, taller opening; a higher ratio means a longer, narrower one. Both eyes stay visible because an average can hide differences.
Check for hooded eyesUpturned or downturned: corner direction
The corner line is measured against your face's horizontal, not the photo frame. Direction gets a stricter pose check, so it can be withheld while the opening result still stands.
Measure your canthal tiltHooded eyes and monolids are about the upper-lid skin fold. The detector finds the opening edge and corners, not the crease, so that check is left to a relaxed look in the mirror. Try the upper-lid mirror check.
The eye shape detector's landmark model supplies positions in the image. We convert x and y using the actual photo width and height before measuring, which avoids stretching a rectangular photo into square-coordinate geometry. A five-point fitted facial line defines the horizontal reference. The ratio and angle calculations are deterministic; a language model does not choose their values.
Each width is the Euclidean distance between the inner and outer corners. Each height is the distance between the selected upper and lower lid points. The two raw ratios are averaged, then rounded to two decimals before the 2.60 and 3.30 boundaries are applied. A ratio above 5 in either eye, or a zero opening, leaves the outline available and asks for a clearer aperture.
The inner-to-outer vector is projected onto the fitted face-horizontal and upward axes, reversing the outward sign between eyes. We average the raw eye angles and then round to one decimal. Values below 2° use the downturned reference; 2–7° is the level reference; above 7° is upturned. A direction is withheld within 1° of either boundary.
Direction requires a four-point landmark-depth reference. Its rounded pitch must stay within ±3° and yaw within ±10°, and the angle must be clear of the boundary zones. An unavailable or unsuitable reference withholds direction while keeping a valid opening. This reference includes a 0.7° pitch offset; it is not a calibrated three-dimensional head-pose measurement.
Eye shape reference: three separate dimensions
Opening, corner direction and upper-lid crease describe different things. These original diagrams keep the dimensions separate so you can combine the observations that fit your eyes.
1. Visible opening
Compare corner width with open-eye height. These ranges are defined labels for the measured ratio.
Round
Mean width-to-height ratio below 2.60.
Almond
Mean ratio from 2.60 through 3.30, inclusive.
Elongated
Mean ratio above 3.30; a narrower visible opening.
2. Corner direction
Read from inner to outer corner against the fitted face horizontal. The level reference includes a gentle positive slope.
Downturned reference
Mean angle below 2°. Reliable labels also need a clear boundary and suitable pose.
Level reference
Mean angle from 2° through 7°, inclusive.
Upturned reference
Mean angle above 7°. This is a direction description.
3. Upper-lid crease
Observe a relaxed eye in a mirror. This row is visual guidance and is not an automated result.
Visible crease
A crease and a strip of upper-lid skin remain visible with the eye open.
Hooded appearance
An overlying skin fold covers some or all of the crease or mobile lid.
Monolid appearance
No distinct upper-lid crease is visible in the relaxed view.
Illustrations show independent dimensions. The crease row is a visual guide; its appearance is not inferred from your mesh measurements.

How we handle photosAn AI eye shape detector with an iris colour estimate
A ring of visible iris pixels is sampled, skipping the pupil and outer edge, and sorted into one of nine coarse colour labels. Room light, glare and contact lenses change the pixels, so treat it as a photo estimate.
Find your colour seasonPoint choices, formula and boundary indicator
The fitted line uses indices 10, 151, 6, 2 and 152. Each row below lists corner endpoints, then upper/lower opening endpoints in the original image. The complete visible-lid contour is also drawn so you can inspect whether the selected spans follow the photographed eye.
- Original image left
133 ↔ 33 / 159 ↔ 145- Original image right
362 ↔ 263 / 386 ↔ 374
Per-eye ratio = corner distance / lid-opening distance. Mean = round((raw left ratio + raw right ratio) / 2, 2 decimals).The opening indicator is round(clamp(nearest boundary distance / 0.35 × 100, 0, 100)). A reading within 0.12 of either threshold is marked near-boundary. This describes the category decision, not confidence in the landmarks.
The browser reads a small ring of visible iris pixels from the same prepared photo, scaled proportionally to at most 1600 pixels on its longest side. The pupil centre and outer iris edge are excluded. The result is a coarse colour bin for sampled image pixels, together with their actual pooled swatch.
The radius comes from two opposing iris-boundary points. Eyes with radius below four sampling pixels are skipped. The retained ring spans 35–85% of that radius, and a pixel is removed if any RGB channel exceeds 235. Each participating eye needs at least 20 retained pixels. One eligible eye can provide a result, with limited consistency.
White balance, coloured room light, glare, contact lenses and surrounding shadow affect the sampled values. The eye shape detector's rules do not add a hidden mask for eyelashes, eyelid skin or reflections below the brightness cutoff. Check another evenly lit photo before interpreting a colour name as a stable observation.
Nine coarse labels and mixed samples
Unrounded mean RGB is converted to hue, saturation and value. The ordered rule checks dark pixels first, then low saturation, then warm, yellow-green, green and blue hue ranges. It uses V 0.20, S 0.13, gray V above 0.45, warm V 0.42 and S 0.45, and hue boundaries 48°, 72°, 165°, 265° and 330°. The outputs are dark brown, brown, light brown, amber, hazel, green, blue, blue-gray and gray.
Every retained pixel contributes equally to the pooled RGB. Two matching eye bins give higher sample consistency. A specific disagreement among light-brown, amber, hazel and green can produce hazel when at least one eye is hazel or green. Other disagreements, or one usable eye, remain low consistency. These labels are heuristic summaries, not statistical probabilities.
Use the eye shape detector result as a starting point for a small experiment, then judge the effect with your eyes open in ordinary light. Your preference matters more than matching a class name. Crease visibility, comfort, existing makeup and eyewear fit still need their own observation.
Try a thinner line first and check where it remains visible when you relax. The eye shape detector's corner direction can help you compare the natural line with a drawn wing. Adjusting the wing changes the drawing, not the measured corners.
Compare a little emphasis at the centre with emphasis toward the outer edge. Look at both eyes together and keep products comfortable. A ratio alone cannot choose a lash map or determine how the upper fold will interact with it.
Use the outline as context while trying frames in person or with a suitable preview. Check temple comfort, bridge support and how the frame sits around the eyes. The eye shape detector does not calculate a glasses prescription or frame-fit measurements.
How to use it in 3 steps
Start with a relaxed, clear view
Hold the camera at eye height with even light across both eyes. Look straight into the lens without raising your brows or widening your eyes.
Check your pose in the true mirrorCheck the eye shape lines before the label
Run the measurement and follow the lid outline and the width and height segments. Flip the preview if it helps; retake the photo if a point misses the eye corner.
Map your eyebrowsRead each result on its own
Compare both ratios and the mean, then see whether a direction was given or withheld and why. The iris colour uses separate pixels. Save a measurement image or the reference chart.

Eye shape detector FAQ
What eye shape do I have?
Upload a straight-on photo to this eye shape detector. It measures each eye's opening and corner direction, then compares them with the reference eye shapes.
Can you change your eye shape?
The underlying shape is set by bone and soft tissue and shifts slowly with age. Makeup, lashes and brows change how it looks; surgery is a medical decision for a clinician.
What lashes suit my eye shape?
Longer lashes at the outer edge lift downturned eyes, while centre emphasis opens up almond or round eyes. The lash map tool turns your eye geometry into a starting map.
What is the most attractive eye shape?
No eye shape is objectively most attractive. Almond eyes are often praised, but expression and styling matter more. This eye shape detector does not rate looks.
What are almond shaped eyes?
Almond eyes are longer than they are tall, with gently tapering corners at both ends. Round, hooded, monolid, upturned and downturned are other common descriptions.
What is my eye shape camera?
You can take a photo with your camera here and it is analysed like an upload. The tool reads one still photo, not live video.
What are the different eye shapes?
Common descriptions include almond, round, hooded, monolid, upturned, downturned, deep-set and protruding. Many eyes combine two of them.
What is the most common eye shape?
Almond is often called the most common, but shares vary between populations and charts. Your result is a measurement, not a ranking.
Why are my eyes different shapes?
Small differences between the eyes are normal. Head tilt and expression can exaggerate them in photos, so compare both readings on a straight-on picture.
How to shape eye brows?
Start from your own brow start, arch and end points rather than a template. Eyebrow mapping measures them on your photo.
Is eye shape genetic?
Largely, yes. Eye shape is inherited, while age, weight and lid skin change it gradually over time.
Is this eye shape detector free online?
Yes. The opening, direction, iris estimate and image download are free; only the optional full face report is paid.
Can the eye shape detector also show my eye colour?
Yes. It samples visible iris pixels and gives a coarse colour label with the actual pooled swatch, as a photo estimate.
Can I check my face shape and eye shape together?
Use the face shape detector for your outline and this tool for your eyes; both read the same kind of front photo.
Can this eye shape detector tell if I have hooded eyes?
Not reliably. It finds the lid opening and corners, not the skin fold. The hooded eyes guide explains a quick mirror check.
Does the eye shape detector upload my photo?
No. Measurements run in your browser and the free result stays on your device. A paid report asks for separate consent before any upload.
