Blade sizing
Which blade fits your guitar?
Two questions. The neck widens as it runs toward the body, so the right blade depends on how wide your neck starts and how far up it you play.
Pick your brand and we'll fill in a likely nut width. Specs drift between models and years, so treat it as a starting point, not gospel.
The nut is the slotted strip the strings cross at the headstock end. Most modern acoustics are 1¾″.
Think about where you actually put it, not where you could.
Answer both questions above and your blade size appears here.

| 1‑11/16″ | Yamaha FG800 & APX600 · Taylor GS Mini · Martin LX1 · Blueridge BR‑160 · Takamine GD93 · most Epiphone |
|---|---|
| About 1.72″ | Most Gibson acoustics · Seagull S6 |
| 1‑3/4″ | Martin D‑18 and current Standard Series · most Taylors including the 414ce · Alvarez AF30 |
| 1‑7/8″+ | 12‑fret guitars · older Martin 0 and 00‑28VS · Blueridge BR‑341 · Breedlove Solo Concert |
Specs drift. Two guitars both listed as 1‑3/4″ can measure differently once the neck is finished, and Martin's high‑performance taper reaches the same width at the 12th fret as their older 1‑11/16″ necks. If the answer matters, measure it.
Playing a 12‑string? Straight answer: we didn't design it for one. The 2.1″ blade will physically fit most 12‑strings, but you'll be fighting the knob to get enough tension across twelve strings. It works. It isn't fun. Buy accordingly.
Classical or nylon‑string? No. Classical necks start around 52mm at the nut and widen from there, which is past the reach of even the 2.1″ blade.
Fretboard radius? Not something you need to check. Silicone bumpers on the blade absorb the difference between roughly 9″ and 18″ — which covers every steel‑string in common production. Martins are typically 16″, Taylors 15″, Gibsons 10″–12″.
Sizing Guide
Published specs drift, so the surest way to know is to measure. Print this at 100%, make two cuts, and you'll have a nut-width ruler and both blade sizes at actual size to lay against your fretboard. Takes about a minute.
