Putting Break Simulator

Why You Under-Read Every Putt

Research consistently shows that amateur golfers under-read the break on putts by 60-80%. On a putt with 12 inches of true break, the average golfer plays only 4-5 inches. The result: the ball misses on the low side almost every time — what instructors call the "amateur side."

The physics of a breaking putt are counterintuitive. A ball rolling on a slope is constantly accelerating sideways. As it slows down near the hole, the break effect increases dramatically — the last few feet of a putt break more than the first few feet. This is why speed control and break reading are inseparable skills.

Green speed amplifies break. A putt that breaks 6 inches on a slow municipal green (Stimp 9) will break 12+ inches on a fast country club green (Stimp 13). Most golfers don't adjust enough for speed changes between courses.

This simulator gives you a visual estimate of break based on putt length, slope, direction, and green speed. Use it to calibrate your reads. Find a putting instructor who can help you dial in your green reading permanently.
