I think it might be fifteen
No, it isn't an exact number. It's all relative, as described below.
The scale length on an Electric Guitar (or any guitar) is the average of the measurements of the length of each string from the point where they touch the nut to the point where they touch the bridge. This is the length of the section of each string that vibrates and creates the musical note. (The sections of each string that are between the nut and the tuning peg, and between the bridge and the tailpiece, do not appreciably contribute to the sound of the string.)
Scale lengths vary from manufacturer to manufacturer, but generally most modern electric guitar scale lengths are between 24 3/4" to 25 1/2 ". The same is generally true of steel, brass, or bronze-stringed acoustic Guitars. Classical and Flamenco acoustic guitars usually have slightly longer scale lengths, to facilitate the looser nylon strings used on these guitars. Extended range electric guitars (such as 7 or 8 string models) can have scale lengths exceeding 27". Bass Guitar scale lengths are most often 34", but can be as short as 26" and as long as 36". In general, the lower the pitch range of the instrument, the longer the scale length will be (which is why most basses have longer scale lengths than guitars).
The scale length of a guitar or bass affects the feel of the instrument and the sound of the instrument when it is being played. Shorter scale guitars are easier to play due to the lower string tension shorter scales produce. Longer scale guitars generally sound fuller and brighter on their lower notes, while shorter scale guitars generally sound fuller (but not necessarily brighter) on their higher notes. Sound and feel, however, are very subjective, and are influenced by many other factors, not the least of which is the gauges of the strings that are on the instrument at the time.
A person could easily make a study out of this subject, and never run out of new information to consider. I know, because I have. The physics that get involved when you actually measure the "functional" scale length of an instrument (as altered by the gauge of the string, the string tension, the "break-angle" of the string as it passes over both the nut and bridge, and other factors) would amaze you!
Lastly, NONE of the above is written in stone. It's really just a matter of what the manufacturer of the instrument wanted to do with that model.
Neck
The most popular names for Fender Neck guitars are the "Stratocaster" and the "Strat" both being trademark terms belonging to Fender. It would seem that every band you see has one of these guitars.
Bass guitars are similar in appearance to electric guitars. It has a longer neck and can have four to eight strings. The most common bass guitar has four strings.
I'm not sure about all of them, but i know that the sz720 has a set neck.
Yes. Typically classical guitars have wider necks, some dreadnought guitars have wider necks than most thin-body guitars. Always play a guitar before you buy it to see if it's what you want and if it fits you and your playing style.
The term "scale length" in relation to guitars refers to the distance between the nut (the top of the neck) and the bridge of the guitar. It affects the tension of the strings and the overall feel and playability of the instrument.
Taylor's Big Baby Guitars has a scale length of 25.5 inches, a body length of 19.5 inches, a body width of 15 inches, and a body depth 4 inches. The neck width is 1 and 11/16 inches.
Neck
For short, fat fingers, guitars with a shorter scale length and a wider neck are typically more comfortable to play. Consider trying out guitars with a shorter scale length, like a Gibson Les Paul or a Fender Mustang, and a wider neck, such as a classical guitar or a custom-made guitar designed for players with shorter, thicker fingers.

look up any famous guitar brand like BC Rich to Gibson , their websites will tell you all about the woods used , the length of the neck down to what kind of tuners they use.
The best places to purchase double neck guitars are Amazon for their variety and price comparison and Gibson's website as they are a brand that make this type of instrument.

Smaller guitars can be easier to play for some people because they have a shorter scale length and narrower neck, making it easier to reach the frets. However, larger guitars may have a fuller sound and more resonance. Ultimately, the ease of playing a guitar depends on the individual's hand size and playing style.
The advantages of a 3-bolt strat neck design in electric guitars include easier adjustability, improved sustain, and a more stable connection between the neck and body, resulting in better overall tone and playability.
A set neck guitar is one where the neck is glued in very carefully instead of screwed on as in bolt on necks. A neck through is one where the neck is actually part of the guitar body.
