ExampleWhat Is Lash Mapping?
Lash mapping is the plan drawn before extensions or clusters go on. The technician divides the lash line into zones, marks a length in each, and the shape of the finished set follows from where the longest lashes sit: at the outer corner for a cat eye, over the pupil for a doll eye, held across the iris for an open eye, at the outer iris edge for a squirrel. The zones are anatomy; the lengths are the design.
The catch is that the map is usually drawn on a generic eye diagram, or on a closed eye at the salon. This tool finds the five zone marks on your open eye (inner corner, inner iris edge, centre, outer iris edge, outer corner), draws each map's lashes on your photo at their real length through the iris ruler (11.7 mm across in almost every adult), and reads your opening shape, corner orientation and eye spacing to say which map the mapping guides would pair with your eyes, and why.
The Five Lash Maps: Cat Eye, Doll Eye, Open Eye, Squirrel and Natural
8 · 9 · 10 · 11 · 10 mm
Natural
Follows the way lashes already grow: short inside, longest over the outer iris edge, a short taper at the corner.
Suits: Almond and upturned eyes, wide-set eyes, anyone who wants the lash line they have with more of it.
8 · 10 · 12 · 10 · 8 mm
Doll eye
One peak over the pupil with both corners short. Opens the eye vertically and rounds it.
Suits: Elongated (narrow) eyes, wide-set eyes, monolids. Rounds a round eye further, so not the first pick there.
9 · 11 · 12 · 12 · 10 mm
Open eye
The longest length held across the whole iris, so the eye reads open rather than peaked. The flattest of the five maps.
Suits: Hooded eyes and monolids, where a short inner zone disappears under the lid; a long, narrow eye that wants height.
8 · 9 · 10 · 12 · 13 mm
Cat eye
Lengths rise all the way to the outer corner. Elongates the eye and pulls the corner outward and up.
Suits: Round eyes and close-set eyes, which it stretches sideways. Pulls a downturned corner further down and pushes wide-set eyes apart.
8 · 10 · 12 · 13 · 11 mm
Squirrel
The cat eye's lift with the peak brought in to the outer iris edge, so the corner itself stays short. Lifts without dragging.
Suits: Downturned eyes (the lift sits at the outer iris edge, not the corner), hooded eyes, round eyes that want length without a hard corner.
Lengths are inner corner to outer corner, one per zone. Every map is a starting point: for fine natural lashes a lash artist takes every zone down together and keeps the shape. The printable lash map chart has all five at true size.
Lash Map by Eye Shape
The same photo reads your opening shape (almond, round or elongated), your corner orientation (upturned, level or downturned) and your eye spacing (close-set, even or wide-set, placed among first-party faces). Hooded and monolid are your answer: the mesh has no crease landmark. The rules below are what the pairing follows.
| Eye | Map | Why |
|---|---|---|
| Almond | Natural or cat eye | An almond eye already tapers outward and carries any map. Natural keeps its line; cat eye extends it. The tool reads almond from the opening's width-to-height ratio. |
| Round | Cat eye or squirrel | Length on the outer half stretches a round opening sideways. A doll map, with its centre peak, makes a round eye rounder. |
| Elongated | Doll eye or open eye | A long, narrow opening wants height, not more length: the peak over the pupil adds it. Cat eye makes a long eye longer. |
| Hooded | Open eye or squirrel, with a D or L curl | The fold hides the inner zone and anything flat, so the length is held across the iris and the curl does the lifting. You tell the tool your lid is hooded; the mesh cannot see the crease. |
| Monolid | Open eye or doll eye, with an L or M curl | Monolid lashes tend to grow straight and down, so the curl has to turn at the base; an even run of length shows above a lid with no crease. Self-reported, like hooded. |
| Downturned | Squirrel | The peak at the outer iris edge lifts the eye while the corner itself stays short. Cat eye puts the length on the corner and pulls it further down. Mapping guides split on this one; the tool follows the lift-without-drag school. |
| Upturned | Natural or cat eye | The corners already lift. Natural leaves them alone; cat eye follows the line you have. |
| Close-set | Cat eye or squirrel | A short inner zone and a long outer half read as more space between the eyes. The tool measures the inner-corner gap against the eye width and places it among first-party faces. |
| Wide-set | Doll eye or open eye | A centre peak draws wide-set eyes inward; outer-corner length pushes them further apart. |

Getting an Honest Map
Face the camera squarely
The map is drawn on each eye separately, so a tilted head is fine, but a turned head foreshortens one eye. Under 10° of turn keeps both sides honest.
Eyes open, nothing on them
Squinting narrows the opening and changes the shape read; extensions, strip lashes and heavy liner move where the lash line appears to be. Map the eye you have, then plan the lashes.
Answer the lid question
The mesh traces the lash line but has no crease landmark, so hooded and monolid are your answer, not its guess. The maps and the curl re-rank when you change it.
Read it as a starting point
Eye width carries about ±1 mm through the iris ruler, and the lengths are the conventions lash technicians map from. A lash artist will shorten every zone together for fine natural lashes (about 3 mm past the natural lash is the working limit) and keep the shape.
Frequently Asked Questions
What is a lash map?
A lash map is the plan a lash technician draws before applying extensions or clusters: the lash line divided into zones from the inner corner to the outer corner, with a length written in each. The map decides the shape of the finished set (cat eye, doll eye, open eye, squirrel, natural) because the shape is made by where the longest lashes sit. This tool divides your own upper lid into the five zones lash artists mark, draws the lashes of each map at true scale on your photo, and recommends one from your measured eye shape, corner orientation and eye spacing.
How do you map lashes by eye shape?
Round eyes take length on the outer half (cat eye or squirrel) so the opening reads longer; elongated eyes take a centre peak (doll or open eye) for height; almond eyes carry almost any map. Downturned corners want the peak brought in to the outer iris edge (squirrel) so the corner stays short; close-set eyes want a short inner zone and a long outer half; wide-set eyes want the length over the pupil. Hooded lids and monolids want the length held across the iris and a stronger curl. The tool measures the opening, the corners and the spacing from your photo and applies those rules, with the reasons printed.
What is the best lash map for hooded eyes?
An open-eye map (length held from iris edge to iris edge, about 9-11-12-12-10 mm) or a squirrel map, with a D or L curl. A hooded fold hides a short inner zone and anything with a flat curl, so the common advice from lash technicians is to keep the inner corner short, hold the length across the iris, and let the curl rather than extra length lift the lash clear of the fold. Outer-corner length (a cat eye) tends to sit under the hood. This tool does not detect hooding (the mesh has no crease landmark): you tell it, and it re-ranks the maps.
What lash map suits almond eyes?
Almost any. An almond eye already tapers toward the outer corner, so a natural map (8-9-10-11-10 mm) keeps that line and a cat eye (8-9-10-12-13 mm) extends it. The tool reads almond when the opening's width-to-height ratio sits between the round and elongated bands, then lets the corner orientation and eye spacing decide between the two.
What is the difference between a cat eye and a squirrel lash map?
Where the peak sits. A cat eye rises all the way to the outer corner (8-9-10-12-13 mm), which elongates the eye and pulls the corner out. A squirrel map peaks at the outer iris edge and drops again at the corner (8-10-12-13-11 mm), which lifts the eye without dragging the corner. That is why the tool recommends squirrel for downturned corners, where a cat eye would pull the eye further down, and cat eye for round or close-set eyes, where the extra length is the point.
Which lash lengths should I use?
The maps run from 8 to 13 mm, which is the range lash technicians map most sets in. Lash artists keep an extension within about 3 mm of the natural lash, so if your own lashes are short, take every zone down by the same amount and the shape stays. The tool shows each zone's width on your eye in millimetres (eye width divided by five), so you know how much lash line each length covers.
How many cluster lashes do I need per eye?
It depends on the cluster width, which varies by brand (roughly 4 to 10 mm per segment). Divide your eye width by the width of the clusters you bought: the tool prints the eye width in millimetres, so a 28 mm eye takes about five 6 mm clusters, one per zone, or more of a narrower cluster. Lay the longest ones in the peak zone of your map.
Is this lash mapping tool accurate?
It is an accurate estimate of your eye's geometry, not a prescription. The opening shape and corner orientation come from the same engine as the eye shape detector; the eye width and the zone widths are in millimetres through the iris ruler (11.7 mm across in almost every adult), with about ±1 mm of spread. The lengths and the pairings are lash-technician conventions from published mapping guides, which disagree in places (downturned eyes most of all); the tool states which school it follows. Lid type is self-reported.
Does this lash map tool upload my photo?
No. The face mesh runs in your browser, on your device, and the map is drawn there. Only the resulting measurements (not the photo or the mesh) are saved so the free tools can be improved.
The maps and pairings follow published lash-technician mapping guides: LashBase, A Guide to Eye Shapes, Lash Mapping and Curls (maps and curls by eye shape; squirrel and L curl for hooded lids); Lash Affair, Lash Mapping: How to Design Lash Extensions for Every Eye Shape (the five zone landmarks, the almond example lengths, shorter outer corner for downturned eyes); Moxie Lash, Lash Mapping Guide for Lash Clusters (cluster counts and lengths by map; the opposing view on downturned eyes).
