Pick gauge by genre: thickness and material picks for every guitar style
Reviewed by the Change Your Strings editorial team ·
Pick gauge sits in three working bands: thin (.60mm and below) for acoustic strumming and rhythm-pop; medium (.73mm to .88mm) for indie, classic rock, and country; heavy (1.0mm to 1.5mm) for metal, metalcore, prog, and djent. Material follows tone goal: celluloid for vintage warmth, Tortex (Delrin) for the metal-rhythm canon, Ultex for djent precision and extended-range, nylon for jazz Jazz III precision. The 1.14mm purple Tortex sits at the absolute center of working metal rhythm; the Jazz III sits at the center of working metal lead.
The pick-gauge cheat sheet
Pick choice carries as much tone weight as gauge or amp. Most working guitarists settle on a single pick spec across decades; the wrong pick spec for your genre fights every other tone choice you make. Here's the working map.
Gauge by genre
Material primer
Pick material drives tone almost as much as gauge. Three materials cover 95% of working guitarists:
Tortex (Delrin polymer). Dunlop's proprietary Delrin formulation, introduced 1981 to replace tortoise-shell picks. The industry-standard durable pick material. Consistent grip across sweat-soaked playing sessions; doesn't shatter when dropped on hard floors. The metal-rhythm canon (1.14mm purple) lives here. Tortex is color-coded by thickness: red .50, orange .60, yellow .73, green .88, blue 1.0, purple 1.14, white 1.50.
Ultex (Ultem polyetherimide). Dunlop's brighter, stiffer, more durable polymer. Outlasts Tortex 3-5x but is more brittle. The djent and extended-range canon (1.14mm Ultex Sharp) lives here. The Petrucci Jazz III signature is Ultex; most modern prog-metal players use Ultex variants.
Nylon. The original Jazz III material. Warmer, rounder attack than Tortex or Ultex. The red Jazz III 1.38mm is the canonical jazz pick; the black Stiffo nylon Jazz III XL is the metal-side variant of the same shape. Nylon is the warmer, more vintage-feeling pick material.
Celluloid (Fender Heavy 351). The vintage-rock canon. Eric Clapton, Stevie Ray Vaughan, Billy Gibbons all play celluloid Fender Heavy 351. The material is warmer than Tortex, less durable, and grippier when sweaty (some players love this; some hate it). Vintage rock and blues lives here.
Coin and unconventional picks. Brian May plays a British sixpence coin. Billy Gibbons sometimes uses a Mexican peso. These unconventional picks deliver harder, brighter, more metallic attack than any production polymer; the trade-off is wear on guitar strings is dramatically faster. Niche.
Shape primer
Three shape categories cover most production picks:
Standard 351. The all-purpose pick shape. Comfortable for most picking-hand sizes, good for both rhythm and lead, the default Dunlop and Fender shape. Most beginner picks are 351.
Jazz III. Small, sharp-tipped pick designed for precision lead work. Originally developed for jazz; became the metal-lead canon over the past 30 years. The Jazz III XL is the larger version of the same shape for players whose hands feel cramped on the small original.
Triangle / Big Stubby. Three identical picking corners on a single pick — never need to rotate it for a fresh tip. Used widely in country, bluegrass, and acoustic strumming. Less common in metal.
Sharp tip variants. The Tortex Sharp, Ultex Sharp, and Tortex Flow all add a sharpened tip to a standard 351-style body. The sharpened tip delivers more transient articulation; useful for djent, modern metalcore, and prog-metal where the gate triggers on the transient.
Working canon: documented player picks
Sourced from manufacturer signature pages, Premier Guitar Rig Rundown coverage, and Dunlop's artist roster. Not all the working-pro guitar canon is signature-SKU material; many players use a standard production pick that suits their genre lane.
Quick-pick guide by guitar setup
If you're not sure where to start, match the pick spec to your guitar setup:
- Strat or Tele in E standard, indie or rock genre: Tortex Standard 1.0mm blue, or Fender Heavy 351 celluloid. The all-purpose rhythm lane.
- Les Paul or SG in E standard, hard-rock genre: Tortex Standard 1.14mm purple, or Hetfield White Fang 1.14mm. The metal-rhythm canon.
- 7- or 8-string in drop tuning, prog-metal genre: Ultex Sharp 1.14mm, or Petrucci Jazz III 1.5mm. The djent precision lane.
- Acoustic dreadnought, folk or singer-songwriter genre: Tortex Standard .73mm yellow, or Fender Medium 351 celluloid. The acoustic strumming lane.
- Hollow-body archtop, jazz genre: Standard Jazz III red nylon 1.38mm. The jazz precision lane.

Frequently asked questions
What gauge pick should a beginner buy?
.73mm yellow Tortex. Thick enough to give controlled attack on rhythm strumming, light enough that wrist fatigue isn't an issue across a long practice session. The Tortex material is also forgiving on grip — it doesn't sweat-slip the way celluloid does. Once you've identified your genre lane, step heavier (metal) or lighter (acoustic-only) from there.
Why do metal players use thick picks?
Pitch stability and transient definition. A thin pick (under 1.0mm) flexes under hard down-picking, which causes the pitch of the note to bend slightly under attack. On a high-gain rig, that pitch bend smears the chord or the chug. A thick pick (1.14mm and up) holds its shape under hard attack, delivering the transient cleanly so the gate triggers correctly and the guitar reads as in-tune through the amp.
Why do jazz players use the Jazz III?
Precision and articulation. The Jazz III is small (smaller than a standard 351) and sharp, which lets jazz lead playing have surgical control on every note. The size also reduces wrist movement on fast alternate-picked passages. The 'Jazz' in the name is historical — the pick was developed for jazz players in the 1970s — but the shape became the standard precision pick across modern metal lead work too.
What pick does Eric Clapton play?
Fender Heavy 351 celluloid. Clapton has played the same pick for decades; the celluloid material gives the warmer, rounder attack his blues-rock lead playing is known for. The 351 shape is the all-purpose lane. Other vintage rock players in the same celluloid Fender Heavy lane: Stevie Ray Vaughan, Billy Gibbons (though Gibbons famously also uses Mexican peso coins for some lead work).
What pick does James Hetfield play?
Dunlop Tortex Flow 'White Fang' 1.14mm — his signature SKU. Built around his exact specification: Flow shape (sharper than standard 351), 1.14mm Tortex, custom Hetfield bevel, white finish for stage visibility on dark guitars. The standard equivalent without the signature is the Dunlop Tortex Standard 1.14mm Purple.
What pick does John Petrucci play?
Dunlop John Petrucci Signature Jazz III 1.5mm Ultex — his signature SKU. Standard Jazz III shape at 1.5mm thickness in Ultex with a polished tip and raised JP grip. Built around his exact spec for Dream Theater's prog-metal lead playing.
