I have a #11 metal club head (45 degree face). How long should the shaft be?
I would always want to know the weight of the clubhead. Clubhead weight plus shaft weight and grip weight allows us to calculate swingweight based on different club lengths.
Typically between 40 and 41”. Here’s the link to a chart that should help you. https://www.golfworks.com/images/art/StdLengths.pdf
