7 Types of Needles Used for Tattooing

To start this comprehensive guide on tattoo needle sizes and uses chart, one must understand the types of needles used.

Here are the different types of tattoo needles:

1. Round Liner (RL)

Round liner needles create small, circular formations. They are most commonly used as lining needles.

These tattoo needles are designed to produce a crisp and clean line, making them ideal for OUTLINING tattoos.

RLs come in VARIOUS sizes, ranging from 3 to 14, with each size having its designated purpose.

The SMALLER the number on the needle, the THINNER the line it will create; conversely, larger numbers will result in thicker lines.

2. Round Shader (RS)

Tattoo artists primarily use round shader needles for SHADING and coloring tattoos. As the name implies, these tattoo needles come in a round shape, with multiple needles of varying sizes grouped on a bar.

Unlike round liner needles, they’re NOT designed to create sharp lines, but to fill areas with color or shading.

The SIZE of the needle determines how thick the line will be. Smaller numbers between 5 to 8 result in thinner lines, while larger numbers between 9 to 14 will produce thicker lines.

It’s important to note that round shaders should NEVER be used for outlining as they won’t produce crisp edges.

3. Flat Shader (FS)

Flat tattoo needles are a variation of round shader needles used for the same purpose: shading and coloring.

They have the same size range as round shaders but with MORE groups of tattoo needles on each needle bar, allowing for smoother coverage.

Unlike round shaders, flat needles allow for SMOOTHER gradients in shading as they apply less pressure to the skin. The downside is that they take longer to apply because of their larger size.

You can also use flat needles for outlining tattoos if you need a thicker line than the one a round liner will produce.

But it’s important to note that these needles are not designed for this purpose and should only be used when NECESSARY.

Pro Tip: Tattoo artists should always start with a round liner needle when outlining and then switch to a flat shader if they need thicker lines.

4. Magnum (M1)

Magnum needles are shader needles designed to fill larger areas more QUICKLY than standard shaders. (1) They comprise 2 rows of needles, with each row having 5 to 7 smaller needles grouped on a bar.

These tattoo needles produce thicker lines than round shaders or even flat needles and can be used for shading and coloring but also for outlining tattoos if you need a thicker line.

Magnum needles offer GREATER coverage and are perfect for creating bolder, more vibrant tattoos. They come in sizes from 7 to 14, with the higher numbers producing thicker lines.

5. Bugpin

Bugpin needles are a special type used mainly for creating fine details and LINEWORK on tattoos. They come in sizes from 0 to 5, with the lower numbers producing thinner lines than regular needles.

These tattoo needles are great for outlining and creating delicate, intricate details as they apply LESS pressure to the skin than standard needles, resulting in smoother edges and more precision.

You can also use them for shading if you need a finer line than what a magnum or round shader can produce.

6. Curved Magnum Shader Needle

Curved magnum shader needles are designed to provide GREATER control when shading and coloring tattoos. They consist of rows of 5-7 needles, each row curved in a U shape.

This allows the artist to shade or fill in an area more EVENLY than regular magnum tattoo needles, resulting in smoother gradients and transitions. They come in sizes from 7 to 14, with higher numbers producing thicker lines.

These needles are great for larger areas such as chest pieces or full arm sleeves that require more coverage, but you can also use them for outlining tattoos if you need a thicker line than what a round liner can produce.

7. Double Stack Needles

Double-stack needles are specially designed for creating EXTREMELY precise linework and details.

They comprise 2 rows of needles stacked on top of each other, with each row having 5 to 7 smaller needles grouped on a needle bar.

These needles come in sizes from 0 to 6, with the lower numbers producing thinner lines than regular tattoo needles.

They can outline tattoos and create delicate details and fine line work that requires precision and accuracy.

The double stack configuration also REDUCES skin trauma, making them perfect for intricate designs.

Pro Tip: When starting, it is best to try different tattoo needles to find the one that works for your style and technique.

4 Types of Needle Diameters Used in Tattoos

The 4 most common types of needle diameters used for tattoos are as follows.

  1. 8 or 0.25 mm is used for outlining and precise details.
  2. 10 or 0.30 mm is used for outlining, shading, and filling in colors.
  3. 12 or 0.35 mm is primarily used for shader needles and cover-up work.
  4. 14 or 0.40 mm is used for mag shading, coloring, and bold outlines.

Needle Counts and Groupings Used in Tattooing

The needle count and grouping used in tattooing refers to the NUMBER of needles on a bar. Most standard shader or liner needles will have 2 to 3 needles, while magnum needles typically have 5 to 7.

Double stack needles will usually have 4 to 6 small needles grouped for increased control when creating intricate details.

Pro Tip: Start with the smaller needle sizes and increase the size as needed.

Needle Codes and Their Meanings

Besides the needle size and count, tattoo needles are also CODED to indicate their type.

  • RL stands for round liner.
  • RS stands for round shader.
  • F stands for flat.
  • M1–M8 stand for magnum (with the number after the M indicating the size).
  • DS stands for double stack.
  • RM stands for curved or round magnum.

Check the table below to find out the best tattoo needle type for you.

What Is Taper?

Taper refers to the SHAPE of the needle. It is measured in millimeters and indicates how pointed or flattened a needle is at the tip.

A rounded taper will have a more blunted tip, while a sharper taper will have a more pointed tip. Sharper tapers are usually used for outlining, while blunted tapers are best for shading.

Configuration and Arrangement of Tattoo Needles

The configuration and arrangement of needles refer to the PATTERN in which the needles are arranged on a bar.

Most standard tattoo needles will be aligned horizontally or diagonally, while double-stack needles may have 2 rows of smaller needles stacked together for increased precision.

Pro Tip: Don’t forget to sanitize your tattoo needles after every use.

Factors to Consider When Choosing a Tattoo Needle

First, you’ll want to determine what KIND of tattoo you’re creating. Different needle sizes and types are designed for different tattoos and can create vastly different results.

The SIZE of the tattoo needle also matters, as smaller needles are best used for detailed work, and larger ones are better suited for shading and filling in colors.

You should also consider the SKIN type of your client. If the skin is thicker, you may need to use a larger tattoo needle to penetrate it. If the skin is thin and delicate, you’ll want to use a finer needle to avoid damaging it.

Finally, consider your STYLE of tattooing. Some artists prefer particular needles for certain types of tattoos and techniques, so finding the tattoo needle that works best for you is essential.
