As the name suggests, round liner tattoo needle configurations only serve the purpose of making lines and hard edges. It is as a photo-realistic technique because the line doesn’t exist in nature.

They are not an ideal tool for covering larger surfaces or shading. Liner tattoo needles are easily recognizable because the needles are available in a tight group together and end in almost a point.

It allows the tattoo artist to create a sharp, crisp mark on human skin. They are perfect for technical work and tiny details.

When it comes to art and especially painting, a liner paintbrush helps make hard edges and lines. The liner paintbrush is what we are mimicking in the tattoo industry. That way, we’re able to use the same technique to create the same effect.

Liner tattoo needle configurations

Liner tattoo needle configurations are usually involve the use of long tapered needles. Some manufacturing companies also offer them in extra-long tapered versions. As we already mentioned in our previous “tattoo needle categories” blog post, these can come from 3 commonly used tattoo needle gauges.

  • .25mm – FINE – #8 is the standard system (US) designation
  • .30mm – NORMAL – #10 is the standard system (US) designation
  • .35mm – FAT – #12 is the standard system (US) designation

Note: ALL REBEL Liner configurations belong to the LONG tapered group.

When a tattoo needle involve the use of .25mm – FINE – #8 wire gauge, it is commonly called BUGPIN. 

Note: Don’t confuse the term “gauge” with the term “taper”!


The name “Bugpin” probably refers to the fine gauge pins that people use for pinning butterflies. It is because the .25mm long tapered needles can be so sharp and thin like the pins for displaying the butterflies.

The number of soldered needles range from a single (1) liner to around 18 needles. This amount usually increases in odd number configurations like 3, 5, 7,9, 11, etc. Round liner tattoo needle configurations may not belong to more than 18-needle configurations.

The general ID or mark of this group in the tattoo industry is RL = Round Liner. The number of needles and configuration type results in the name. So a 7-needle round liner would be 7-RL,  an 18-needle round liner would be 18-RL, and so on.

Of course, we use the same system here at REBEL. But we also insert our brand abbreviation: RTC – stands for REBEL TATTOO CARTRIDGES.

REBEL Tattoo Cartridge – 9 Round Liner = RTC-9RL

Now, I would like to explain the total diameter (thickness/gauge) of different needle configuration. It hasn’t been clearly explained (at least not by any tattoo artists I know) and there are a lot of misconceptions out there.

First of all, let me familiarize you with the REBEL Liner cartridge inventory. Then, I’ll explain the logic as to why we offer this kind of selection.

NOTE: ALL REBEL Liner configurations belong to the LONG tapered group.

REBEL Liners vary in common gauges along with the number of needles that make up the configurations. All configurations have a final WORKING DIAMETER or working gauge/working thickness, which is one of the most important properties.

Working diameter

Working diameter is the diameter of the final needle configuration that we use for tattooing. This determines how thick of a line we can create.

    • REBEL Needle configuration from .25mm (#8 US) needles. The term for this is BUGPIN Liners
    • The REBEL Needle configurations from .30mm (#10 US) needles. he term for this isSTANDARD/Round liners
    • REBEL needle configurations from .35mm (#12 US)  needles. he term for this is POWER Liners

This chart explains the correlation between liner needle configurations and the wire gauge they are made from. 

The Metric system is easier to understand and represents the correlations. But, at the same time, you can study the standard system measurements as well.

Needle Configurations Sizes

As you can see, we have the same needle configurations for all 3 sizes of needles (same color code). But there is still a difference among them because they are made up of different diameter/gauge needles. Therefore, they can provide the same working diameter.

Logistically, smaller gauge needles need a higher quantity in order to reach a certain size, compared to bigger gauge needles. This is why we have an overlap between their’s working diameter.

When analyzing the chart above, we can come to a conclusion. For example, lets take the working diameter of the 7 Round liner needle configuration from #8 (.25mm). It is the same as or equal with the 5 Round Liner configuration from #10 (.30mm) and the 3 Round Liner needle from #12 (.35mm).

Check out the chart below, which is organized by working diameter and configuration.

Working Diameter Sizes

Looking at the chart, you can conclude that there are 5 working diameter sizes that can be manufactured from all 3 gauges of needles. These include 0.7mm, 0.85mm, .98mm, 1.10mm and 1.2mm (green columns)

Additionally, a 0.60mm working diameter may come from .25mm and .30mm needles. Similarly, a 1.35mm working diameter size may come from .30mm and .35mm needles (blue columns).

The rest of the working diameters are only from a certain gauge (red columns).

REBEL Round Liner inventory pays careful attention to common sense. We have set up to cover the wide available range of working diameters to satisfy all tattoo artists and their unique needs.
