Before I articulate them, let me say that these are just size guidelines issued for those who want some place to start from in considering guitar size. But like everything in life (shoes, articles of clothing, undergarments), you wont really know that they fit until you try them on. This is not an attempt to tell anzone what size guitar they must have, instead if you have been fighting your guitar or uncomfortable with it, these numbers may help you find a solution. A guitar is a tool for sound production, and in the end it must fit in the hands of the player.
After looking at every ones measurements, the most highly correlated measurement versus scale length preferrence was thumb to pinky distance, with a R squared correlation of 0.6. In non mathematical terms, that is a pretty good fit of the data to a line, in other words, the bigger the thumb to pinky distance, the longer the scale length that was preferred and vice versa. Other measurements, like index to pinky, which I had expected to be the most highly correlated measruement, had lower correlation values, like 0.4, 0.05 and 0.06. R squared values less than 0.5 indicate not good fits of lines to data.
The best fit curve has the formula of 0.46*(thumb to pinky distance in mm)+547mm. For me, with my 240mm span, this worked out to 656mm, which is where I personally am most comfortable. Time to commission a Hauser!
There was not enough data submitted for pinky ring index stacks to develop correlation data. However, if your finger stack is above 40mm, consider a 54mm neck witdh.
The chart at the head of a similar thread on this topic should be revised, as well, since it expressed guitar size in terms of index to pinky distances, and this does not correlate well with player preferences. The revised chart, using commonly available neck sizes and expressing scale length versus the thumb to pinky distance, would be as follows
Thumb tip to pinky tip span of 250+ 664mm scale length
Thumb tip to pinky tip span of 230 to 250 656mm scale length
Thumb tip to pinky tip span of 210 to 230 650mm scale length
Thumb tip to pinky tip span of 190 to 210 640mm scale length
Thumb tip to pinky tip span of 170 to 190 630mm scale length
Thumb tip to pinky tip span of below 170 615mm scale length
I hope that this information will be of use to people who are still looking for that guitar that fits their hands. Happy Playing!
I'm sorry but I'm totally disagree with this approach...
It is too simplistic and even not useful for many cases...
It is too simplistic because:
1. If someone wants to make any correlations in this then, not one, but many measurements should be used.
a) the whole length of the hand
b) the length of the hand between elbow and thumb
c) the size of shoulders
d) the size of the chest
e) age of the player
f) the physical condition of the person - because different people has different speed, power, could do different stretches...
and other things etc.
Guitar is an instrument with which we do a lot of work, in this work we use many parts of our body and it is a way too simplistic to thing that our playing will be best and depends only on distance between two fingers and size of guitar...
my right hand is between pinky and thumb - !! 260 mm !!
according to this I should play 664 mm ??
But I hate 664 mm guitar, and prefer 650mm scale and 42mm between 1 and 6 string, or shorter (I'm fine with 550 mm Lute)
I think that larger size of guitar and longer length of the neck will create more health problems, than benefits for player!
- back pain, spine , nerve, tendinitis etc problems.
650 mm is already large enough for any player and even a bit smaller and shorter guitar will be more ergonomical less physically demanding to play.
It would be very interesting if someone would make a study of guitarists health in time before year 1900, when most of guitars were smaller.
Myself I never heard/ read about massive amount of health complains (like it is now) connected with guitar playing then... and by the way many guitarists played in standing position.
I have a large hands, but I don't like long and wide necks
Yes guitar must be as convenient as possible, but it is not as simple as shoes size (my shoes size 13 by the way) .
