What’s the Difference Between 0.03, 0.05, and 0.07 Lashes?

Whether you’re a new lash artist or a seasoned pro, understanding lash tray thicknesses is key to creating safe, stunning lash sets your clients love. One of the most common questions we hear is: What’s the difference between 0.03, 0.05, and 0.07 eyelash extensions?

These numbers refer to lash diameter, or the thickness of each individual extension in millimeters (mm). Choosing the right diameter affects everything from the final look to how healthy and long-lasting the lashes are on your client.

In this blog, we’ll break down the differences between 0.03, 0.05, and 0.07 lash trays, how each thickness impacts volume and style, and which to use based on your client’s natural lashes and desired look.

Lash Diameter 101: Why Thickness Matters

Before we dive into specific sizes, let’s quickly cover why lash diameter is so important.

Lash extension thickness directly impacts:

• Weight on the natural lash
  

• Volume of the final set
  

• Fan size (number of lashes in a handmade fan)
  

• Overall styling possibilities
  
  

Each client’s natural lashes can only support a certain amount of weight. That means the thicker the extension, the fewer lashes you can safely apply per fan.

That’s why understanding and choosing the correct diameter is essential—not just for the beauty of your sets, but for the health of your clients’ natural lashes.

0.03 Lashes – Ultra Lightweight for Mega Volume

Best for: Mega Volume fans (8D–20D)
Skill level: Advanced
Style: Full, fluffy, high-impact volume

0.03 lashes are the thinnest extensions available and a must-have in any lash artist’s kit if you offer mega volume lash sets. Their featherlight structure allows you to safely build large fans—sometimes up to 20 lashes per natural lash—without risking lash damage or premature shedding.

Because they’re so fine, 0.03 lashes require refined technique. They’re especially responsive to pinching and shimmy fanning methods, making them ideal for artists who’ve honed their craft.

💡 Pro Tip: A 10D fan made with 0.03 lashes weighs less than one classic 0.15 lash—making mega volume a safe option when done right.

0.05 Lashes – Perfect for Full Volume Sets

Best for: Full Volume fans (5D–10D)
Skill level: Intermediate to Advanced
Style: Bold, dense, but still lightweight

0.05 lashes offer a beautiful middle ground: they’re thicker than 0.03s but still light enough for volume work. They’re ideal for creating dense, full volume eyelashes that deliver drama without compromising lash health.

Many lash artists favor 0.05 lashes because they’re easier to control than 0.03s, yet still soft and flexible. They’re a top pick for fans in the 5D–10D range, delivering coverage and fullness that lasts.

If your client wants glam but isn’t ready for mega volume, 0.05 is your go-to.

0.07 Lashes – Versatile for Light Volume and Hybrids

Best for: Light Volume (3D–6D), Hybrid, and Classic sets
Skill level: Beginner to Intermediate
Style: Soft, natural volume

Looking for a lash that does it all? Meet 0.07. These lashes strike the perfect balance between thin and thick, making them incredibly versatile. They’re one of the most popular lash diameters and work beautifully in hybrid and light volume sets.

While still lightweight, 0.07 lashes can safely be fanned into 3D–6D sets, offering a fuller look than classics, but with a softer finish than dense volume. They’re also a solid option for classic lash sets on clients with fine or sparse natural lashes.

💡 Pro Tip: If your client is nervous about going full glam, start with a hybrid set using 0.07s to ease them in.

Choosing the Right Diameter: What to Consider

When selecting lash tray thicknesses for your client, ask yourself:

1. How healthy are their natural lashes?

Thicker lashes = more weight. Always match the lash diameter to the strength of the natural lash.

2. What look are they going for?

Soft and wispy? Go with 0.07. Bold and dense? Try 0.05. Dramatic and ultra full? Reach for 0.03.

3. What is your skill level?

Beginners often find 0.07 easier to work with, while 0.03 requires more advanced fan-making skills.
