Tattoo needle groupings: the cheat sheet
Bookmark-and-forget reference: the groupings you will actually meet, what they are typically used for, and the two spec lines (diameter, taper) that change how any of them behaves. For the full explanation, read the needle guide — this page is the shorthand.
A quick-reference table of the needle groupings that matter — what each RL, RS, RM and M1 size is typically used for — plus diameters and taper in thirty seconds.
Liners (RL)
| Size | Typical use |
|---|---|
| 1RL–3RL | Fine line, micro detail, delicate script |
| 5RL | Standard outlines, most script |
| 7RL–9RL | Bold outlines, traditional linework |
| 11RL–14RL | Very bold lines, small solid fills |
Shaders (RS)
| Size | Typical use |
|---|---|
| 3RS–5RS | Small-area shading, tight spots, texture |
| 7RS–9RS | Small fills, soft accents, whip texture |
Magnums (M1 and RM)
| Size | M1 (weaved) | RM (curved / soft edge) |
|---|---|---|
| 5–7 | Small fills, colour blocks | Soft shading in small areas |
| 9–11 | Mid-size packing and shading | The realism workhorse — smooth gradients |
| 13–15+ | Large fills, big coverage | Large soft shading without hard edges |
The two spec lines that change everything
- Diameter: #08 (0.25 mm) = control and fine detail · #10 (0.30 mm) = the versatile middle · #12 (0.35 mm) = ink flow, bold lines, packing.
- Taper: short = fast, assertive ink deposit (lines, solid colour) · long/extra-long = gradual deposit (soft shading, greywash).
5RL (#10 or #12) for lines, 3RL (#08 or #10) for detail, 9RM for shading, 11M1 for packing. That small shelf executes a remarkable share of everyday tattooing.

Frequently asked questions
What is the difference between M1 and RM magnums?+
M1 is a weaved magnum with needles in two straight offset rows — efficient for packing and shading with a defined footprint. RM is a curved (soft edge) magnum whose rounded profile avoids hard edges, making it the go-to for smooth, soft shading.
What needle sizes should a beginner keep in stock?+
A compact set covers most practice and early work: 3RL and 5RL for lines, 9RM for shading, 11M1 for packing. Add sizes when a specific job demands them rather than stockpiling upfront.
Does a bigger needle grouping hurt the skin more?+
Not inherently — a correctly used large magnum can be gentler than a small liner overworked across the same area, because it covers ground in fewer passes. Technique and pass count matter more than needle count.
