Shot Dispersion Calculator
Turn your average miss and typical spread into a dispersion cone and target width at any distance — and a smart aim point so you stop short-siding yourself.
Aim for the pattern, not the pin
Good course management is really dispersion management: you pick the aim point that keeps the most of your cone on safe ground. Once you can see how wide your pattern is at a given distance and which way it leans, a lot of “bad breaks” turn out to be predictable misses you aimed straight into.
Pair this with the yardages you trust from the Club Distance Chart, and post the scores it saves with the Golf Handicap Calculator.
Frequently Asked Questions
What is shot dispersion?
Dispersion is the pattern your shots make around your target instead of a single line. Even good players scatter shots into a cone that widens with distance, and understanding your own cone is the foundation of smart course strategy: it tells you how much room you actually need, which side you tend to miss, and where the safe aim point is. This tool turns your typical pattern into numbers you can use over a shot.
How do I measure my bias and spread?
Hit a handful of shots with one club on the range or a launch monitor and note two things at a chosen reference distance: your average miss (how far left or right the middle of the pattern finishes — that's your bias) and how far your shots scatter to each side of that centre (that's your spread). Enter positive numbers for right and negative for left. Even a rough read from ten shots is far more useful than assuming every shot goes dead straight.
Why should I aim away from the pin?
Because your pattern has width, aiming straight at a tucked pin sends half your cone into the bunker or water beside it. By aiming your pattern's centre at the safe middle of the green — and, if you have a directional bias, aiming the opposite way so the pattern centres on target — you keep far more of the cone on safe ground. That's the difference between short-siding yourself and leaving a straightforward next shot, and it's how good players turn misses into pars.
How does the pattern change with distance?
It grows. Because dispersion is a cone spreading out from you, the same swing produces a wider pattern the farther the shot flies — a spread of ten yards at 150 becomes proportionally wider at 200. This calculator scales your pattern linearly to the target distance, which is why longer clubs demand more margin and why aiming at a flag is far riskier with a long iron than with a wedge.
A planning aid built on a simple linear model. Real dispersion isn’t a perfect cone, so leave yourself margin around hazards.
