How to Read Greens: Slope, Break and Pace Explained

Reading a green means working out how a putt will curve and how fast it will roll before you hit it. Greens are rarely flat: they slope, and a putt rolling across a slope curves (or breaks) toward the low side. Get the read right, add the right pace, and more putts drop.

Start with the big picture

Before you reach the green, look at the land around it. Greens tend to drain toward lower ground, water or the front of the green, and the slope of the surrounding hills usually continues onto the green. Seeing the overall tilt from 30 yards away is often easier than from right above the ball.

Find the high side

Look from behind the ball toward the hole. Which side of the hole is higher? The putt will curve away from the high side and down toward the low side.
Look from the low side of the putt, halfway between ball and hole. Slopes are easiest to see from below.
Feel it with your feet. Walking the line, you can often sense which way the ground tilts and whether it's uphill or downhill.

The steepest line through the hole, the way water would run off, is the fall line. A putt straight up or down the fall line doesn't break at all. Putts across it break the most.

Pace changes the break

How much a putt curves depends on how fast it's rolling:

A firmer putt breaks less, because it spends less time on the slope.
A gentle putt breaks more, especially in its last few feet, when it's slowest.
Uphill putts need more pace and break less. Downhill putts need a soft touch and break more.

Most good putters aim to roll the ball so that, if it missed, it would finish about 12 to 18 inches past the hole. That pace takes some of the break out and gives the ball a chance to drop.

Pick a line and a spot

Once you've read the break, choose the point to aim at (some way to the high side of the hole), then pick a spot a few inches in front of your ball on that line, like a mark in the grass. Aiming at a near spot is easier than aiming at a far one. Then think only about pace.

Other things that affect a putt

Grain: on some grasses, the blades grow in one direction. Putting with the grain is faster; against it, slower. Grain often grows toward the setting sun or toward water.
Two-tier greens: a step in the green changes the pace dramatically. Land your approach on the right tier.
Wet greens are slower and break less; dry, firm greens are faster.

Practise the read

Before a round, roll a few putts across a slope on the practice green from different distances. Watch how much they curve at different speeds. That feel is worth more than any formula.

Reading greens in One Fairway

In One Fairway, putting works on the same idea: the game shows you the green, and you do the reading.

No putt line is drawn for you. The game never shows a predicted path, so the read is yours, just like on a real course.
The shot planner gives a reading of the green's slope, so you can see which way it tilts before you choose your aim.
You set the putter's range for the length of the putt, aim to the high side, and judge the strength of the stroke. The default aim is a touch past the hole, and the rest is up to you.
Every putt teaches you something: after each shot, the result shows how far it went and how far it finished from the hole.
Try the two tiers: Stonepine's 17th hole has a two-level green, where landing on the wrong tier leaves a tricky putt up or down the step.
Inside about 3 feet in a match, your opponent may give you the putt. Gimme rules.

Questions

Which way does a putt break?
Toward the low side of the slope. A putt straight up or down the steepest line through the hole (the fall line) doesn't break at all.

Does the speed of a putt change how much it breaks?
Yes. A firmer putt breaks less and a gentle putt breaks more, especially in its last few feet.

Does One Fairway show a putting line?
No. The game never draws a predicted path. The shot planner gives a reading of the green's slope, and the read is yours.
