Eye shape is not one label. It is four independent traits measured together: the outline of the opening, whether the lid has a visible crease, the angle of the corners, and where the eye sits in the socket relative to its neighbor.
That is why almost nobody fits a single category, and why advice built on one label so often fails. Read the traits that describe you and ignore the rest.

Outline traits
How tall the eye is relative to its width, and how sharply it tapers at the corners.
A visible crease, an iris slightly covered top and bottom, and a gentle taper at both corners.
Almost any liner shape works. A soft wing extending the natural taper is the default that flatters without changing the eye.
The whole iris is visible with white showing above or below it, and the eye reads open rather than tapered.
Extending liner horizontally past the outer corner lengthens the eye. Heavy liner all the way round shortens it further.
Lid traits
Whether a crease is visible when the eye is open, and how much lid space that leaves you.
A smooth lid with no visible crease between the lash line and the brow bone.
Gradient shadow from the lash line upward creates depth. Liner needs to be thicker than on a creased lid to stay visible when the eye is open.
A fold of skin from the brow bone covers part or all of the crease when the eye is open.
Place shadow and liner where they are visible with the eye open, not where they look right closed. Keep the lash line tight and lift the outer third.
Angle traits
The line from the inner corner to the outer corner, measured in degrees rather than described.
The outer corner sits clearly above the inner corner, giving a positive canthal tilt.
This is the tilt most liner techniques try to fake, so almost none is needed. Balance with slightly more definition along the lower lash line.
The outer corner sits below the inner corner, giving a soft downward line at the outer edge.
End liner before the natural corner and flick upward from a point just inside it. Curling the outer lashes does more than any product.
Position traits
Spacing across the face and depth within the socket, both read against the width of one eye.
The gap between the inner corners is narrower than the width of one eye.
Keep the inner corners light and concentrate depth at the outer third. Brows that start slightly further apart open the whole midface.
The gap between the inner corners is wider than one eye width.
Reverse the close-set advice: darken the inner corners and keep the outer third softer to draw the eyes visually together.
The eye sits back under a prominent brow bone, which casts a natural shadow across the lid.
Light and reflective shades on the lid bring the eye forward. Dark shadow in the crease deepens a socket that is already deep.
The eyeball sits forward in the socket so the lid appears convex rather than flat.
Matte mid-tones across the lid recede. Avoid shimmer on the center of the lid, which pushes it further forward.
Questions
The four questions people ask most before they measure anything.
Yes, and almost everyone does. Eye shape is three separate traits measured at once: the outline (almond or round), the lid (monolid, hooded or creased) and the position (close-set, wide-set, deep-set, protruding) plus the angle of the corners. A perfectly ordinary description is "round, hooded and wide-set", all three at once.
Canthal tilt is the angle of the line drawn from the inner corner of the eye to the outer corner. A positive tilt means the outer corner sits higher, which reads as upturned; a negative tilt means it sits lower, which reads as downturned. It matters mainly because it decides which direction eyeliner should travel to work with the eye rather than against it.
The bone structure does not, but the soft tissue does. Loss of elasticity in the upper lid means many people who had a clearly visible crease in their twenties read as hooded by their fifties. Swelling, sleep, allergies and hydration all change the apparent shape from day to day, which is why one photo is a snapshot rather than a verdict.
Outline, spacing and canthal tilt measure reliably from a straight-on photo because they are simple distances and angles between landmarks. Hooding and depth are harder, because both depend on how light falls across the brow bone and how relaxed your brows are. Take the photo with a neutral expression, eyes open normally, and no upward brow lift.
Where to go next
Each of these builds on the traits above rather than repeating them.
Eye advice sits inside a larger frame. The seven face shapes decide the outline everything else works within.
Deep-set and protruding eyes want different lens depths, so eyewear is where eye position pays off first.
Shadow placement follows lid space, but which shades read well follows your skin tone and season.
The detector reports outline, tilt, lid space and spacing separately, so you get all four traits rather than one label.
