Mapping is the blueprint for the lash set: it determines the length and curl of the extensions at every point of the eye, from the inner corner to the outer corner. It is what separates a decent lash set from one that truly enhances the eyes.
Here is how to build eyelash extension mapping step by step, with four starting examples: natural, doll, cat eye and foxy.
What is eyelash extension mapping?
A mapping, or lash plan, is the distribution of lengths, and sometimes curls, along the whole lash line. It is prepared before the application: the eye is divided into zones, then each zone is assigned a length.
With the same extensions, you can create a very subtle or a very elongated look, simply by changing how the lengths are distributed.
Steps to build a mapping
- Observe the eye: its shape (almond, round, deep-set), the eyelid (hooded or not) and the distance between the eyes.
- Observe the natural lashes: length, direction, density and strength. They set the maximum length you can safely apply.
- Choose the effect with the client: natural, doll, cat eye, foxy.
- Divide the eye into zones: inner corner, center and outer corner. Five to seven zones are enough.
- Assign a length and a curl to each zone.
- Prepare the extensions: MIX boxes combine several lengths and make zone-by-zone application easier.
- Apply while checking the balance: look at the client face-on, with her eyes open, and compare both eyes regularly.
Four basic mappings
| Mapping | Lengths in mm, from inner to outer corner | Effect |
|---|---|---|
| Natural | 8 · 9 · 10 · 11 · 11 · 10 | Gentle progression, subtle look |
| Doll | 7 · 9 · 11 · 12 · 10 · 8 | Peak at the center of the eye, round and open look |
| Cat eye | 7 · 8 · 9 · 10 · 11 · 12 | Lengths increasing toward the outer corner |
| Foxy | 6 · 7 · 9 · 11 · 12 · 13 | Rapid rise toward the outside, very elongated look |
These lengths are starting examples: shorten or lengthen them according to the length and strength of each client's natural lashes. An extension should never be much longer than the natural lash that carries it. There are also corrective mappings, which compensate for asymmetry or hooded eyelids.
What about curl in mapping?
Length isn't everything: you can also vary the curl. A C at the inner corner for softness, a CC from the center to the outer corner to open up the eye, an M on hooded eyelids. These choices are covered in detail in our guide to B, C, CC or M curl.
Which lengths do you need to build your mapping?
Athéna, Aura and Hestia come in single lengths from 6 to 13 mm, and in MIX boxes from 4 to 18 mm depending on the product. The Athéna MIX 4–6 mm and Aura 5 mm mini boxes provide the short lengths needed at the inner corner, without opening a large box for just a few extensions.
Mapping mistakes to avoid
- Too much length at the outer corner: it weighs the set down and can make the eye look droopy.
- Abrupt transitions: jumping straight from 9 to 12 mm creates a visible step effect.
- The same mapping for every client, without looking at the shape of the eye.
- Forgetting to compare both eyes during the application: a mapping is checked face-on.
The role of your tools
A mapping only holds true if the isolation is clean and the fans are even. Precise tweezers help (see our guide to choosing your tweezers), as does a thickness suited to each lash (see the guide on extension thickness). Eyelash extension tape helps with holding and positioning during the application.
The choice of technique also influences the mapping: see our comparison Russian Volume, Classic or Hybrid Volume.
In summary
Observe the eye and the natural lashes, choose the effect, divide the eye into zones, then assign lengths and curls while staying within what the lash can support.
Débo Beauty's classic lashes and Hybrid Volume training (taught in French), in Carouge, covers advanced mapping and the natural, doll, cat eye, foxy and corrective effects. The full GEMELLA range is in the Eyelash extensions collection.
