Measure your canthal tilt in 60 seconds
The direct answer, in plain words — the full script of our 60-second canthal tilt explainer:
What is canthal tilt? And can you actually change it?
It's the angle of a line from your inner eye corner to your outer one. Upward reads positive. Level or down, neutral or negative.
It's a measurement of an angle. Not a rating of you.
Tilt your head back, and the same eyes read more positive. That's the camera, not your face.
Can you change it? Honestly, no. It's set by the bone around your eye. And you didn't do anything wrong.
You can change how it reads. Lens slightly above eye level, chin a touch down. That changes the photo, not your face.

What is canthal tilt?
Canthal tilt is the angle between the medial canthus (inner corner of the eye) and the lateral canthus (outer corner), measured against a horizontal baseline when looking straight ahead. It is one of the most studied facial metrics in aesthetic medicine and is consistently linked to perceived attractiveness, youth, and facial harmony.
The measurement is simple: draw an imaginary line from the inner corner to the outer corner of each eye. If that line tilts upward toward the temples, you have a positive canthal tilt. If it's level, you have a neutral tilt. If it tilts downward, you have a negative canthal tilt.
Most people have a slight positive or neutral tilt. Significant negative tilt (below -3°) is associated with fatigue, premature aging, and is one of the primary targets of cosmetic eye surgery. Strong positive tilt (+5° to +10°) creates the "almond eye" or "fox eye" aesthetic that dominates high-fashion and looksmaxxing discussions.
Quick glossary — terms used on this page
Skim if you already know them. Each term links back to the term's full definition where one exists.
The inner corner of the eye, where the upper and lower eyelids meet near the nose. Reference point for the start of the canthal-tilt measurement line.
The outer corner of the eye, where the upper and lower eyelids meet toward the temple. Reference point for the end of the canthal-tilt measurement line.
The horizontal opening between the upper and lower eyelids. Length and shape of this opening combine with canthal tilt to produce "almond" vs "round" eye reads.
Cosmetic surgery that lifts the lateral canthus tendon to add positive tilt. Less invasive than canthoplasty; results are subtler and partly reversible with healing.
Cosmetic surgery that re-positions the lateral canthus structurally for permanent tilt change. Higher complication rate than canthopexy; revisions are common.
Visible white (sclera) above or below the iris when looking forward. Higher scleral show often pairs with neutral or negative tilt; minimal scleral show is part of the "hunter eyes" composite read.

What does your canthal tilt look like?
Reference the abstract examples below to calibrate your reading. Each card shows a stylized eye-pair with the inter-canthal axis (dashed) and tilt arc against horizontal.
Negative tilt
Outer canthus sits lower than inner. Reads as downturned or tired.
Neutral
Inner and outer canthi sit on the same horizontal line.
Positive tilt
Outer canthus higher than inner. Most rated attractive in perception studies.
What's research-backed vs community-observed
Research-backed: Eye-region geometry consistently appears in attractiveness models (Rhodes 2006, PMID 16318594). Specific canthal-tilt-to-attractiveness studies are less common than overall facial-symmetry research.
Community-observed: The "positive tilt is more attractive" framing is common in looksmaxxing communities and aligns with general findings on eye-area youthfulness signals — but the specific degree-attractiveness gradient is mostly anecdotal, not directly measured in published studies.
Schematic eye references — not real measurements. Actual canthal-tilt math runs on your photo's landmark points.
How canthal tilt is measured
Identify the medial canthus
The medial canthus is the inner corner of the eye — the small pink area nearest the nose where the upper and lower lids meet. This is the starting point for the measurement.
Identify the lateral canthus
The lateral canthus is the outer corner of the eye, farthest from the nose. This is the endpoint of the measurement line.
Draw the canthal axis
A line connecting the medial and lateral canthus forms the canthal axis for that eye. This is typically measured on both eyes and averaged for a bilateral reading.
Measure the angle
The angle between the canthal axis and a true horizontal baseline (parallel to the floor) gives the canthal tilt in degrees. Positive values indicate upward tilt; negative values indicate downward tilt.
AI measurement
Our AI detects 68 facial landmarks from your photo, including precise coordinates for both medial and lateral canthi on each eye. It calculates the canthal tilt angle in degrees and shows your percentile ranking compared to thousands of measurements — far more accurate than manual estimation.
What research says about canthal tilt and attractiveness
Canthal tilt has been studied extensively in both aesthetic medicine and evolutionary psychology. A landmark study by Rhee and colleagues (2007) measuring canthal tilt angles across groups rated at different attractiveness levels found that positive canthal tilt was one of the most consistent predictors of perceived facial attractiveness in both men and women. The effect was cross-cultural — the preference for upward-tilted outer eye corners held across Asian, European, and mixed populations.
Evolutionarily, positive canthal tilt is associated with youth. Canthal tilt naturally decreases with age — the lateral canthus droops as the lateral orbital retaining ligament weakens and periorbital fat redistributes. This means that a positive tilt reads as a youth signal, which is why it correlates with attractiveness ratings.
In cosmetic surgery literature, restoring or creating positive canthal tilt is one of the goals of canthoplasty and canthopexy procedures. Studies on post-operative patient satisfaction and rater attractiveness scores consistently show improvements after tilt correction, supporting the hypothesis that positive canthal tilt is a genuine attractiveness feature rather than a cultural trend.

What our data shows
Our scanner has processed 35,000+ faces, and canthal tilt is one of the most requested single metrics. The reference ranges we calibrate against come from published anthropometric literature, not our own corpus (per-user analyses are not retained): the average adult canthal tilt is +5.2°, the published normal range is 2–10° positive, and most adults sit between 3° and 7° (Farkas, 1994).
The scan computes the angle for each eye from the line between the outer and inner eye corners, averages both eyes, gives full scoring credit across the 2–8° band, and displays 4–7° as the ideal range. Canthal tilt is also the strongest of the three markers in the hunter eyes test, and the surrounding eye-area geometry feeds the brow bands scored in the masculinity test.
Can you improve your canthal tilt?
Reduce body fat
ModerateLower body fat reduces periorbital fat pads and under-eye puffiness, which creates a cleaner canthal angle and makes a neutral tilt read closer to positive. Dropping from 20%+ to 13-15% body fat has a visible effect on eye area definition.
Improve sleep quality
Small but fastSleep deprivation causes periorbital edema (swelling around the eyes) which droops the lateral canthal area and makes a positive tilt look neutral. Good sleep hygiene — 7-9 hours, reduced sodium, and head-elevated sleeping — visibly improves the eye area within days.
Photo angle
Significant in photosCamera angle dramatically affects how canthal tilt reads in photos. Shooting from slightly above eye level (the camera looking slightly downward at you) tightens the under-eye area and makes positive tilt more pronounced. This is the standard angle for attractiveness-optimized photos.
Canthopexy / canthoplasty surgery
Permanent, high riskCanthopexy repositions and tightens the lateral canthal tendon to lift the outer corner. Canthoplasty involves cutting and repositioning the canthus itself for more significant structural change. Both are legitimate cosmetic procedures but carry surgical risks and require experienced surgeons.

Canthal tilt is one of the most over-indexed metrics in the looksmaxxing community. The angle is mostly bone-determined, but reads on a face can shift dramatically with brow position, under-eye support, and photo angle. The map below converts your measured tilt into the correct intervention band — most readers benefit from the soft-tissue and photo levers long before considering anything clinical.
Already in the asset range. No intervention. Lever: photograph in good light at eye-level so the asset reads. Avoid downward angles that flatten the tilt.
Common, attractive band. Soft-tissue levers (brow lift via training, under-eye care, sleep) maximize what is already there. Photo angle matters more than cosmetic intervention here.
Reads neutral on most faces. Strongest non-clinical levers: brow shape and density, glasses frame angle, hair part position. These shift perception by 2-3° equivalent without surgery.
Genuinely negative tilt is uncommon and a research-not-react read. If a paid audit confirms it as a primary detractor (rare — usually the perceived issue is brow or under-eye, not tilt), only then is consultation reasonable.
The two failure modes this map prevents: (1) panicking on a neutral read because the looksmaxxing forums treat anything below +5° as a flaw, and (2) jumping to canthoplasty when the perceived issue is actually brow shape or under-eye, both of which are far cheaper and reversible.
Frequently asked questions
What is canthal tilt?
Canthal tilt is the angle between the inner and outer corners of the eye, measured relative to horizontal. A positive tilt means the outer corner is higher; negative means the outer corner is lower.
What degree of canthal tilt is considered attractive?
Research suggests +3° to +8° positive canthal tilt is rated most attractive. Neutral (0°) is average. Negative tilt (below -2°) is associated with a tired or sad appearance and receives lower ratings.
What is the difference between canthal tilt and hunter eyes?
Canthal tilt is a specific clinical measurement. Hunter eyes is a broader aesthetic concept involving canthal tilt plus hooded eyelids, low scleral show, and a defined brow ridge. Positive canthal tilt is one component of hunter eyes.
Can I measure my canthal tilt at home?
Yes. Take a straight-on selfie with your head level, then use our free AI looksmaxxing test — it automatically measures your canthal tilt in degrees along with 9 other facial metrics.
Does canthal tilt change with age?
Yes. The lateral canthus naturally droops as the canthal tendon weakens with age, decreasing canthal tilt by approximately 0.5° per decade after age 30 (Farkas, 1994). This is why restoring positive tilt is a common goal of eye-area cosmetic procedures.
Is a negative canthal tilt bad?
No — a mildly negative tilt is within normal human variation. In the published anthropometric data the average adult canthal tilt is about +5.2°, with most adults between 3° and 7° positive (Farkas, 1994), so a negative tilt is simply less common. It can read as tired in photos, but it is one metric out of 17, and lighting, brow shape, and under-eye puffiness often account for more of the read than the angle itself.
What canthal tilt do models have?
No peer-reviewed study has published measured canthal tilts for professional models, so any specific "model tilt" number you see quoted is invented. What the research does support: positive canthal tilt is one of the strongest single-metric correlates of perceived attractiveness, and the published normal range is 2–10° positive (Farkas, 1994). The "model look" people describe usually corresponds to a clearly visible positive tilt — the upper half of that range — combined with brow position and eye shape, not the tilt alone.
Can your two eyes have different canthal tilts?
Yes — small left-right differences are common. The scan measures each eye separately, taking the angle of the line from the outer to the inner eye corner against horizontal, then averages the two for your reported tilt. A degree or two of difference between eyes is ordinary asymmetry: in published symmetry research most faces measure 65–80 out of 100, and self-perceived asymmetry consistently exceeds what is actually measured (Rhodes, 2006).
Does head tilt in a photo affect your canthal tilt result?
Yes, more than almost anything else. Canthal tilt is measured against a horizontal reference line, so if your head is rotated a few degrees in the photo, that rotation is added to or subtracted from the measured angle of both eyes. Take the photo with your head level, the camera at eye level, and your eyes looking straight ahead — and if a result looks off, retake before reading anything into the number.
