01
Geometry first
RL, RS, Flat, straight Magnum and curved or Soft Edge Magnum are useful broad geometry families. Specialty constructions stay separate.
Free tattoo artist utility
Tattoo Needle & Cartridge Finder.
Start with the job, compare a short set of plausible grouping families, and keep manufacturer-specific codes where they belong: attached to the actual product specification.

Structured spec decode
Decode what is actually printed or known.
Physical pin diameter in millimetres is the canonical field here. Gauge numbers, taper labels and specialty suffixes stay attached to the manufacturer context instead of being forced through a universal parser.

Add the literal count if the manufacturer states it.

Not confirmed
The tool does not infer millimetres from a gauge number without manufacturer-backed context.
Needle system
Not specified
System type is descriptive only and does not establish machine compatibility.

How to read the result
A family narrows the comparison. It does not finish it.
The tool stops where cross-brand evidence stops. Geometry, literal count and physical pin diameter can be compared broadly; exact product construction and manufacturer terminology still need the maker's own specification.
02
Millimetres over gauge
Physical pin diameter in millimetres is the canonical comparison field. A printed gauge number stays a manufacturer alias unless its mapping is explicitly sourced.
03
Observed, not prescribed
Counts, diameters and taper tendencies are catalog observations from reviewed current manufacturer lines. They are not exact presets for a tattoo job.
Source model
A small manufacturer-reviewed matrix, not a product database.
Primary manufacturer material was reviewed on 2026-08-12. Each source is authoritative for its own terminology and catalog, not proof that every maker uses the same code.

FAQ
Needle-family questions this tool can answer honestly.
Broad geometry and physical specification fields can be compared. Exact product behavior still belongs to the manufacturer specification and the artist using it.
No. It returns configuration families to consider, with observed catalog ranges, geometry and tradeoffs. It does not turn those observations into a universal prescription for a tattoo.
No. Current manufacturer documentation does not support one global gauge-number mapping. StencilStudio treats physical pin diameter in millimetres as the comparable field and preserves a manufacturer's printed gauge or code only as context.
Because full product codes, gauge aliases, taper suffixes and specialty-family conventions vary by manufacturer. The structured decoder keeps the fields you actually know without fabricating a cross-brand conversion.
No. It is a configuration-navigation tool only. It does not prescribe machine settings, needle depth or hang, hand speed, skin-type choices, healed outcomes or biological effects.
Product catalogs change, specialty terminology is manufacturer-specific, and compatibility is a separate high-maintenance problem. This MVP stays at a small reviewed principles layer rather than pretending to maintain a universal SKU database.
