45 inches was standard for a long time. 45.5-45.75 inches has crept up as the new standard. Many pros se 44.5. A half to one inch should help to try.

If using a driver needs a 3 inch drop, then work with a pro to decide if some driver shortening will help or a mini-driver and not have to swing up will improve direction and distance.

I actually went through this recently at a Titleist fitting. I got fit into a driver built ½” shorter than standard, and it made a huge difference for me.

Before that, I was inconsistent on the face. Once we shortened it slightly, I started finding the center way more often, and my dispersion tightened up.

The surprising part? I gained over 20 yards. Not because I swung faster — my clubhead speed stayed about the same — but my smash factor improved. Better center contact = more ball speed.

I also experimented with different head weights. For me, that didn’t really change performance much — it was more about feel and personal preference. The shaft length adjustment was the real game changer.

It really showed me that efficiency and strike quality matter way more than just raw length.

I’m also interested in what to expect from adding head weight to the driver. Can changed weight affect ball flight and if so how much..

This is what fittings are for. Far too many variables, and different players prefer and need different specs. Some may do better with a 44" driver than a 45.5", some prefer C9 swingweight and others D6. What works for others likely won't work for you. Go see a professional fitter to find what works best for your swing.

Agree with Brock, but one thing I would add is when you go to a fitter be prepared to let them know what you are looking for. Get to know your swing (ball flight, distance, spin rate, dispersion control) and where you are looking for improvement. Everybody's swing is unique to only themselves, and what works for others doesn't always work for you. Make sure you find a qualified fitter.

Might read this article. Discusses some of your questions. My answer would be, as always, go see a PGA professional for help.
