Break chart generator
Enter the Stimpmeter reading and the slope, and it works out how far outside the hole to aim for each combination of distance and side slope. It prints at a size that fits in a yardage book.

These figures assume a pace that would finish 40 cm past the hole. Change the pace and the aim changes with it.
Computed on a uniform plane. Real undulations, uneven grain and wind are not included.
Aim point = the sideways distance, at the hole, from the ball-to-hole line to where you aim
Maximum break = how far the path strays from the ball-to-hole line at its widest
For competition, check Rule 4.3 (use of equipment), the rules on green-reading, and the local rules of the event. These are guideline figures from a physical model, not a guarantee.
How to read and use this chart
Rows are distance, columns are side slope. Each figure is how far outside the hole to aim, in cups (or centimetres). As in the calculator, a positive side slope means the right side is higher; the ball then breaks left, so you aim right by the amount shown.
Start by matching the green speed
One point of Stimpmeter changes the aim by roughly a tenth. Use the figure posted at the course, or what the practice green tells you. If you do not know it, leave it at 10 and move it either side to see what a quicker or slower day would do.
Switch uphill and downhill with the tabs
The same side slope breaks more downhill and less uphill: a softer stroke spends longer rolling, so gravity pulls it further off line. The difference is not small, so always check the front-to-back slope too.
Print it and take it with you
A4 portrait puts uphill, flat and downhill on one sheet; the pocket size prints one table per page, sized for a yardage book. Switch to black and white and the shading becomes hatching and bold rather than colour.
Check the path from any cell
Pick a cell and the Putt Break Calculator opens with those conditions and that stroke already set. Seeing the curve in 3D makes it much clearer what the number means.
Frequently asked questions
If I aim where the chart says, will it go in?
No. The chart is computed on one uniform plane, so real undulations and uneven grain are not in it. And if your pace differs from what the chart assumes (40 cm past by default), the aim changes too. Use it to check your judgement, not to replace it.
What does "×" mean?
No stroke satisfies the conditions in that cell. Most often the slope is too steep for the ball to come to rest, which happens sooner the faster the green. Hover over the cell for the reason.
Why does the side slope only go to 2° by default?
Two degrees is a gradient of about 3.5%. At 3° (5.2%) the ground is too steep for a hole to be cut, so although the figures can be computed you would never meet that situation on a green. You can enter more than 3° if you want to, but it is not in the defaults.
The calculator’s recommended pace and aim disagree with this chart
They answer different questions. The calculator recommends the stroke most likely to hole out given your dispersion; this chart gives the stroke that sends the ball over the centre of the hole and finishes the chosen distance past it. Open a cell in the calculator and you will see the chart’s stroke already entered.
Can I use it in competition?
Check Rule 4.3, the rules on green-reading, and the local rules of the event. Whether a printed chart may be carried varies from competition to competition.
