Through line refers to the imaginary path a golf ball would continue to travel on after passing the hole, assuming it stays on its intended line. It is an extension of the line of putt beyond the cup and is used to help visualize the correct starting direction and break of a putt. Skilled golfers often consider both the line into the hole and the through line to better understand how the ball should roll across the entire putting surface.

How Golfers Say It

"That was on line, just didn’t have the pace through."
"Pick your through line, not just the entry point."
"He read the through line perfectly."
"You’ve got to see it past the hole."

Origin

The concept developed from advanced green reading techniques, particularly among competitive and professional golfers, who began emphasizing not just the entry point of the hole but the full rolling path of the ball beyond it to improve accuracy and speed control.

Rules & Context

Through line is not an official term in the Rules of Golf but is closely related to the defined concept of the line of play and line of putt. It is used in practice and green reading to refine putting accuracy. Considering the through line helps players account for slope, grain, and speed, especially on breaking putts, ensuring the ball enters the hole with proper pace and direction.
