Steve, I was wrong, my pinky to thumb is 7.5" and pinky to index is 5" so your hand is slightly larger than mine. Still, there are charts from the forum below to show where you should be. As mentioned by the poster below (I am on your post so I can't see his post at all, but he mentions about putting a capo on the first fret. He is right that putting a capo on a 650 mm scale length guitar will give you a 615 scale length. I have a Snark 2 model tuner, it will automatically calculate what your guitar should be tuned to, by just reading the tuner.stevel wrote:Interesting. I'm 5'3" on a good day. I'm definitely at the small end of the spectrum of human sizes for a male. If I stretch my thumb and pinky so they're pretty much "in line" with each other on opposite sides of the hand, I too can reach 8" (and 1/4") so it surprises me that some of your hands are that small. Pinkie to index I can make 6".
I started guitar up after 35 years or so and it was after I joined this forum did I know anything about scale length. I have a 1972 Yamaha GC-20D with 663 mm scale length and then realized that after all these years it may have been why I always felt the guitar was too big for me. You can see my guitar in the for sale area and should not be far from the top, but I would not suggest you buy it, obviously. I can play it fairly well, but it is always a stretch.
I have 2 other guitars, my 650 starter Framus guitar and a new since Christmas 650 Silent Guitar that I am now playing. I like the effects of the silent guitar and cause it fairly well. However, I have since tried a 2nd hand Guild 640 and could notice the difference enough to almost buy it.
Then came this forum where all this stuff is mentioned, so I put the capo on my 650 making it a 615 and wow what a difference. Really easy to play and still liked the near 2" nut. I don't think the nut is a big factor when it comes to a short scale guitar. I have even picked up my daughter's "never used" 590 mm and enjoyed playing it, but felt it may be a little too small and the neck definitely narrow at about 1.75".
I love my Yamaha 20D so much for its looks, tone and nice low action I hate to sell it, but in order to buy a good short scale guitar I need to sell my Yamaha.
our hands are about equal and I feel the 615 would be best for me, but a 630 not much in the difference and you probably get a larger selection. I would not go any higher. I know from playing the 640 guild. The capo or 615 was my size even though I was a little larger than the suggested 615 mm in the chart below one of the charts below suggesting I was into the 630, but the 2nd chart had me in the 615 mm. My extensive playing around with the charts and capo along with the ability to play the small 590 mm child's guitar makes me feel that the 615 would be the guitar for me. One othe member on the forum may respond here as she has done a lot od research and is still experimenting between a 580, 615 and owns a 630, but feels it is too large.
Here are the 2 charts I have, I would try and find some guitars to try, that would be the best way.
Two different scales with slightly two different results, but for me #1 seems to work for me!
The 650mm is suitable for those players whose spread between thumb and pinky is 9″ or greater
The 640mm is suitable for those players whose spread between thumb and pinky is 8″-9″
The 628mm is suitable for those players whose spread between pinky and thumb is 7″-8″
***The 615mm is suitable for those players whose spread between pinky and thumb is 6″-7″ (me 7.5")
