Module 8: Lash Mapping and Design

Learn to measure, draw a zoned map and choose between natural, cat eye, doll and squirrel styles to suit each eye shape and set of natural lashes.

Course: Eyelash extensions course from A to Z · Module 8 of 10

Lash mapping is the blueprint for a set: it decides which length, curl and, in volume work, which fan size goes in each zone of the eye. With exactly the same application skills, a good map can open up the eye while a poor one can make it look droopy or heavy. In this module you will learn how to assess and measure, how to draw a map on the eye pad, how to recognise the most requested styles (natural, cat eye, doll, squirrel) and how to adapt them to each client’s eye shape and natural lashes.

Module objectives

  • Assess the natural lashes and eye shape before designing anything.
  • Draw a zoned map using landmarks on the client’s own eye.
  • Choose lengths that respect the natural lash and avoid sudden jumps.
  • Tell natural, cat eye, doll, squirrel and wispy styles apart.
  • Adapt the design to eye shape and achieve a symmetrical finish.

What lash mapping is and why it matters

Mapping means dividing the lash line into zones and giving each zone a length (plus curl, diameter or fan size where needed). It does two jobs: it delivers the look the client wants, and it stops you putting more on each natural lash than it can carry. Lash Affair stresses that published maps are a starting point to customise rather than fixed rules, and that you should not copy one map across every client, or even across both eyes.

Step by step: from assessment to map

1. Assess

Look at the eyes from the front, with the client sitting up and looking straight ahead. Note eye shape, any asymmetry between the two eyes, and the density and length of the natural lashes (Lash Affair). Glad Lash adds further points to check: lash strength, growth pattern, baby lashes and growth direction. Lash Affair assesses under a magnifying lamp and uses the longest natural lashes in the centre of the eye as the reference measurement.

2. Talk to the client

Confirm the look she wants using reference photos. Lash Affair warns that words like “natural” or “dramatic” mean different things to clients and artists. This is also the moment to explain what her natural lashes can realistically support.

3. Draw the map on the pad

  1. Secure gel pads or tape under the eyes so you can draw directly on them; you will find both in our accessories.
  2. With the client looking straight ahead, mark the highest point of the pupil: this is the centre of your map (Glad Lash).
  3. Divide the eye into zones. Glad Lash uses five (inner corner, inner-mid, centre, outer-mid, outer corner); Lash Affair suggests five to seven sections based on landmarks: the inner corner as zero, the inner edge of the iris at about a quarter, the pupil at the centre, the outer edge of the iris at about three-quarters and the outer corner as the end point.
  4. Write the length in each zone, plus curl and diameter where they change.
  5. Repeat for the other eye, adjusting for its differences.

4. Pick lengths the lash can carry

Lash Affair gives a clear rule: an extension should never be more than roughly 2 mm longer than the natural lash it is attached to, and for volume it suggests staying about 1 mm shorter to favour density over length. Its example: a 10 mm natural lash supports a maximum extension of 12 mm. Glad Lash adds two useful rules: avoid jumping more than 2 mm between sections, and put the longest lengths on the strongest natural lashes rather than automatically at the very end of the eye.

Inner corners are kept shorter. Starting figures vary: Glad Lash and Lash Affair’s mapping guide begin at 7–8 mm, while Lash Affair’s length article suggests 8–10 mm. Mixed-length trays are handy for these short zones; browse our lashes range for options.

The most popular lash mapping styles

The sequences below are examples published by Glad Lash (inner corner to outer corner, in mm). They are not recipes: adjust them to the natural lashes in front of you.

Squirrel: defined differently by every source

Lash Affair places the squirrel peak slightly past centre, towards the outer third, as a subtler lift than cat eye. Curacoro describes it as a style with more zones and rapidly changing lengths, similar to cat eye but without large differences in length. If a client asks for “squirrel”, show her a photo to make sure you are talking about the same thing.

Curl is part of the design

Glad Lash recommends choosing the curl for the eye first and then locking in lengths: B or C for a soft natural look, CC for everyday glam, D for a noticeable lift, and L or M for hooded eyes that need lifting. Special curls for hooded lids sit alongside classic and volume fibres in our lashes category.

Adapting the design to eye shape

Eye shapeWhat the sources tend to recommendWatch out for
AlmondVersatile; suits most maps (Lash Affair). Glad Lash suggests doll eye.—
RoundCat eye or squirrel to elongate (Lash Affair, Glad Lash, Curacoro).—
Close-setEmphasis on the outer half: cat eye or squirrel.Keep the inner corner short and light.
Wide-setNatural or doll, with the longest lengths nearer the centre to draw the eyes together (Lash Affair).—
Hooded / monolidDoll or open map with a strong curl (D, L+), placing length and curl higher so they show (Lash Affair).Check with eyes open that the extensions are not hidden.
DownturnedSquirrel or open eye, shortening the outer corner (Lash Affair).Lash Affair and Glad Lash advise against a strong cat eye; Curacoro suggests cat eye for droopy eyes. Sources disagree.

An example from Lash Affair shows the risk with downturned eyes: going long at the outer corner emphasised the droop, and the fix was to shorten it from 14 mm to 10 mm. The same source warns that 14 mm on a weak natural lash will droop and pop off.

Symmetry: two eyes, two maps

  1. Map each eye separately: they are rarely identical, and Lash Affair recommends customising each one so both look balanced when open.
  2. Before finishing, compare both eyes from above: check where the peak length sits and whether the outer corners match (Glad Lash).
  3. Ask the client to sit up and open her eyes: the result that counts is the one seen from the front.
  4. Record the final map on her client card so you can repeat or refine it at her infill.

Common mistakes

  • Making the outer corner the longest by default. Glad Lash calls this one of the biggest causes of droopy-looking sets.
  • Choosing length from the photo rather than the natural lash. An extension too long for the lash holding it will droop and fall.
  • Sudden length jumps. More than 2 mm between sections creates visible steps.
  • Long or heavy inner corners. They look heavy near the nose and can be uncomfortable.
  • Copying the same map onto both eyes. Natural asymmetry becomes more obvious.
  • Not confirming the style with a photo. “Squirrel” or “natural” mean different things to different people.

Module summary

  • Mapping assigns length, curl and diameter by zone; published maps are only a starting point.
  • Assess, talk to the client, draw the map on the pad and adjust each eye separately.
  • According to Lash Affair, an extension should be no more than about 2 mm longer than the natural lash; avoid jumps of more than 2 mm between zones.
  • Natural, cat eye, doll, squirrel and wispy differ mainly in where the peak length sits.
  • Eye shape guides the style, but sources do not always agree (especially on downturned eyes).

Self-assessment

Which landmark does Glad Lash use to mark the centre of the map?

The highest point of the pupil, marked on the pad while the client looks straight ahead.

Your client’s longest natural lash is 9 mm. Following Lash Affair’s rule, what is the maximum classic length you would use?

Around 11 mm (roughly 2 mm longer than the natural lash), and a little shorter for a volume set.

What is the difference between a cat eye and a doll eye map?

A cat eye places the longest lengths towards the outer corner to elongate and lift; a doll eye concentrates them in the centre, over the iris, for a rounder, more open look.

What do you need to be careful about with downturned eyes?

Not lengthening the outer corner by default, because it emphasises the droop. Lash Affair suggests a squirrel or open-eye map with a shorter outer corner.
