Winding length is what's important.
The Electric Bass Scale Length is the measurement from the Bridge Saddle to the Nut. This can also be referred to as the "vibrating length" of the string. On a Jazz Bass (pictured) the "Scale Length" is measured at 34" roughly. What the "Scale Length" does not account for is the distance between the Ball End and the Saddle as well as the Nut to the Tuning Posts.
In the below images the length of the Green Bar represents the "Scale Length" of the bass which is the distance measured from the Bridge Saddle to the Nut. The Red Bar shows where to measure to determine the minimum required winding length of the string needed to fit the bass. This measurement is taken from Ball End to just past the Nut. To find the maximum winding length you must measure from the Ball End to the Tuning Post for the thickest string.
Here is how to properly measure your instrument to find out the correct winding length. There are two measurements you want to take note of.
First measure from the back of the ball end to the tuning post side of the nut. This will give you the "Minimum Required Winding Length" for your instrument.
Then measure from the back of the ball end to the middle of the tuning post. This will give you the "Maximum Winding Length" for your instrument.
The ideal winding length is going to fall right in the middle, but as long as you do not go less than or greater than these measurements then you are using the correct length strings!
