Hi obvious3975,
The SR505 is has 24 frets. Starting from the top and working down, the distance between the 1st fret and the 2nd is 1 3/4", 2nd and the 3rd is 1 5/8", 3rd and the 4th 1 1/2", 4th and the 5th 1 3/8", 5th and the 6th 1 3/8", 6th and the 7th 1 1/4", 7th and the 8th 1 1/8. It continues to get smaill with the smallest distance between fret 3/8". The distance between the 1st fret and the fret just at the body of the bass where the neck is bolt onto the bass is 20 1/2".
Now keep this in mind. I started out worring about my small hands then I realizing I was building a wall in my own mind. Then about that same time I ran across a video clip of a guy playing a bass with one hand. Its in your heart to play so, play. You will overcome phyiscal limitations through learning different techniques.
You have to feel the bass to know it's the right one for you.
