Shopping for lash clusters means reading a lot of codes: 30D, 80D, D curl, 9 to 16 mm. Each one changes how the lashes look on your eye. This guide explains what the numbers mean so you can pick the right set for the look you want, whether that is a soft natural line or a full, dramatic one.
Full disclosure: Pilamie sells lash clusters. We will not tell you ours are the best. Instead, this guide covers what to check on any set, including ours.
Volume: what 30D, 60D and 100D mean
The number before the D tells you how dense each cluster is. A higher number means more lash fibers packed into each cluster, so the result looks fuller and darker. Brands do not all measure it the same way, so treat it as a scale within one brand rather than an exact fiber count.
- 20D to 40D: light and airy. Closest to a natural lash line. A good choice for a first set, for everyday wear, or if your own lashes are fine.
- 50D to 60D: noticeably fuller. Works for most everyday looks if you want visible lashes without heavy liner.
- 80D to 100D: dense and dark. Reads like a dramatic false lash. Heavier on the eye, and the base is more visible if placed badly.
Mixing volumes is common. Many people put lighter clusters at the inner corner and fuller ones toward the outer corner.
Lash cluster size chart
A quick reference for the three numbers you see on a lash cluster box.
| Label | What it measures | Common range | Natural look | Fuller look |
|---|---|---|---|---|
| Volume (D) | How dense each cluster is | 20D to 100D | 20D to 40D | 50D to 100D |
| Length (mm) | How long the lashes are | 8 to 18 mm | 9 to 12 mm | 13 to 16 mm |
| Curl | How much the lashes lift | C, D and stronger curls | C or D | D |
What does 60D mean in lashes?
60D describes a fairly dense cluster: each one has more fibers than a 30D or 40D cluster, so it looks fuller and darker on the eye. It works well for the outer half of the eye or for an evening look. As with all volume numbers, compare it within one brand, since brands do not measure it exactly the same way.
Curl: C, D and beyond
Curl describes how much each cluster bends upwards.
- C curl: a gentle lift. Looks natural, especially on straight lashes.
- D curl: a stronger lift that opens up the eye more. It is the most common curl for cluster lashes and works for most eye shapes.
- Stronger curls exist too, but they can look obviously false and are harder to blend with straight natural lashes.
If your own lashes point down, curl them before applying any clusters, whatever curl you choose. Otherwise the clusters and your natural lashes point in different directions.
Length: picking a range
Lash cluster lengths are given in millimeters. A tray with mixed lengths, for example 9 to 16 mm, lets you build a shape from one box:
- 9 to 11 mm: inner corners and natural looks.
- 12 to 13 mm: the middle of the eye for most people.
- 14 to 16 mm: outer corners, or the center for a rounder look.
A quick rule: your longest cluster should not be much longer than your natural lashes plus a few millimeters, or the result looks heavy and droops.
Natural, wispy or dramatic: matching the look
- Natural: 30D or 40D, D curl, mostly 10 to 13 mm. Use four or five clusters per eye.
- Wispy: mix lengths next to each other, for example 10, 13, 11, 14 mm, so the line looks uneven in a pretty way. Light to medium volume works best.
- Cat eye: short at the inner corner, building up to the longest length at the outer corner.
- Dramatic: 60D to 100D, longer lengths across the whole eye.
Step by step maps for two of these looks: natural-looking lash clusters and wispy lash clusters.
Band and fiber: what else to check
- The base. A thin, flexible base is easier to hide under your natural lashes and more comfortable.
- Black or brown. Black is standard. Brown can look softer on light hair and light lashes.
- What is in the box. Some sets include glue, sealant and remover. Others, including ours, are lashes only. If the bond is included, check that you know what is in it and patch test it.
- Reuse. Most synthetic clusters can be reused a few times if you remove them gently and clean the base. Reviews mentioning reuse are more useful than claims on the box.
How many clusters do you need?
Most people use four to six clusters per eye, so roughly 8 to 12 per full set. A 280 piece tray covers many applications, especially if you reuse clusters. A larger multi-volume set is useful if you want to experiment with different looks.
Our sets, in plain terms
- 280 piece tray: one volume per tray, seven volumes from 30D to 100D, D curl, 9 to 16 mm. A good first box if you already know your volume.
- 640 piece set: four volumes in one box, 30D, 40D, 50D and 60D, D curl, 9 to 16 mm. Useful for mixing and for trying several looks.
Both are lashes only. You will need a cluster bond and a remover from a brand you trust. Once you have your set, our step by step guide to applying lash clusters covers the rest.
