What is the standard string length measurement before and behind the bridge for a full sized violin please?
Thanks,
Sean
I have heard that when you pluck a string behind the bridge it is supposed to be the same note as the string up or down from the one you plucked, but on the playing side of the bridge.
That is achieved by adjusting the length of the string behind the bridge. I could be dead wrong, but I think I was told that once.
Standard string lenght for a 4/4 violin es 327-330 mm. String afterlenght is said to be 1/6 of the vibrating lenght, that is 54.5-55 mm. This string afterlenght leads to a two octaves plus a fifth of the string tone if you bow the afterlenght. But this is the ideal goal with pure gut strings, with the actual strings this is not allways true. I have set up some violins that sounded better with shorter or longer afterlenghts (up to 60 mm).
I was told 325-330mm by a local repair shop. I measured 325mm with the rear of the bridge lined up with the notches in the F holes. If I match the harmonic with the fingered note, the string length comes out to 328mm and the front of the bridge lines up with the notches in the F holes. The same person mentioned the only time you would need to match the harmonic and fingered note is if you use a "Don't Fret". On guitars, you match the 12th fret harmonic with the fingered note using an electronic tuner to ensure it plays in tune in higher positions.
A lot of websites state 330mm for a 4/4 size violin.

I do know that the tailgut can stretch, so measure your afterlength periodically and have it adjusted by a luthier from time to time to ensure optimum set-up for your violin.
