See how launch angle, backspin and wind shape a golf shot's height, carry and landing angle, with modeled trajectories and an interactive launch explorer.
By Golf Club ReferencePublished
How high a golf shot flies, and how steeply it lands, comes mostly from three numbers measured just after impact: ball speed, launch angle and backspin. Launch angle sets the starting climb. Backspin creates the lift that keeps the ball up, and too little or too much of it costs carry. Ball speed scales everything, and wind changes the air the ball has to fly through.
The trajectories on this page come from a physics model of a golf ball, so you can see each effect on its own. They show directions and proportions, not yardages for your clubs.
Three numbers set the flight
Trackman defines launch angle as the vertical angle of the ball's takeoff relative to the horizon. It tracks dynamic loft, the loft on the face at impact, and is usually a little lower than it. Spin rate is how fast the ball rotates about its spin axis just after leaving the face. Ball speed is how fast it leaves.
The loft stamped on a club is a static number. At impact the shaft can lean forward or back, the face can be delivered with more or less loft, and the club can be moving up or down. That is why two golfers can launch the same 7-iron at different angles. As a rule, more loft at impact means a higher launch and more backspin. Our guide to what golf club loft tells you covers the static number in more detail.
Launch angle: the starting climb
Hold ball speed and spin steady and change only the launch, and the shot climbs higher and lands more steeply. Carry grows quickly at first and then levels off.

Illustrative model output for still air at sea level. Carry is the modeled flat-ground carry; bounce and roll are not modeled. Height is in feet and distance in yards, so the vertical scale is stretched.
In this example, going from 7° to 10° adds about 14 yards of modeled carry, while going from 16° to 19° adds about 2. The landing angle meanwhile steepens from about 25° to 46°. A steeper landing usually means less roll, which carry-only numbers do not show.
Backspin: lift that holds the ball up
A spinning ball drags air around with it and gets pushed perpendicular to its path. That push is the Magnus effect, and with backspin it points mostly upward. Golf ball dimples help the ball make the most of it, which is why a well-struck shot can rise after it leaves the face.
Spin decides whether the ball holds its heightFive modeled drives at 150 mph and 12° launch. Only backspin changes.

Illustrative model output. Low spin gives a flat flight that falls early (a knuckling flight); high spin climbs steeply and balloons, trading forward speed for height. Height is in feet and distance in yards, so the vertical scale is stretched.
There is a middle ground. At 1,500 rpm the modeled drive carries about 226 yards and never gets much above 65 feet; it falls out of the sky early, a flight golfers call a knuckleball. At 5,000 rpm it climbs to about 115 feet and balloons, giving back carry to height and drag. In between, around 3,000 rpm for this example, carry peaks.
For context, Trackman lists PGA Tour average driver figures of 10.4° launch and 2,545 rpm, and LPGA Tour averages of 12.6° and 2,506 rpm. Those are averages for tour players with tour ball speeds, not targets for anyone else.
The launch window
Launch and spin work together, so the best launch depends on the spin and the reverse. Mapping every pair shows it at a glance.

Illustrative model output for still air at sea level, carry only. The dark band runs diagonally: a lower launch needs more spin to stay in the air, and a higher launch needs less. Near the top of the band carry barely changes, while the landing gets steeper, which usually means less roll. Bounce and roll are not modeled, so this is the reasoning behind launch-monitor optimizers, not a target for any individual golfer.
The dark band runs diagonally. A low launch needs more spin to stay in the air, and a high launch needs less. That is the logic behind the advice to launch higher with less spin when chasing driver distance. The band is also wide: across many combinations carry changes by only a few yards, so a launch monitor's single best number matters less than staying inside the band.
Wind: headwind hurts more than tailwind helps
Aerodynamic forces grow with the square of the air speed over the ball. A headwind raises that speed, so the ball gets more drag and more lift: it climbs, slows and drops short. A tailwind lowers it, so the ball flies flatter and lands sooner than you might expect.

Illustrative model output with a uniform wind; real wind is usually lighter near the ground and gustier higher up. A headwind raises the air speed over the ball, which adds lift as well as drag, so the shot climbs and falls short. A tailwind lowers both, so the ball flies flatter.
In this example a 20 mph headwind costs the 7-iron about 29 yards, while a 20 mph tailwind adds only about 12. The headwind shot also comes down at about 66°, much steeper than the 44° of the calm-air shot. That asymmetry is why players club up more into the wind than they club down downwind.
Knockdowns, stock shots and high shots
Better players change trajectory on purpose. A knockdown or punch is a lower, shorter-finishing swing that cuts launch and spin to keep the ball under the wind. A high shot does the opposite to stop the ball quickly on a firm green.

A knockdown is usually played with the ball a little farther back and a shorter finish, which lowers launch and spin; a high shot does the opposite. The numbers here only show the direction of each change. Height is in feet and distance in yards, so the vertical scale is stretched.
The modeled knockdown peaks at about 43 feet and lands at about 31°, while the high shot peaks at about 93 feet and lands at about 50°. The carries end up similar. The difference is in height, how the wind affects each shot and what the ball does after it lands.

Illustrative model: drag and Magnus lift on a regulation-size ball, slowly decaying spin and a uniform wind. It does not model bounce, roll, altitude, temperature or a specific ball, so treat the numbers as directions of change rather than yardages for your clubs.
Try a 140 mph ball speed with 1,800 rpm, then raise the launch; carry keeps rising long after it would with 3,500 rpm. Then add a 15 mph headwind to a high-spin shot and watch it balloon.
What this means for older irons
Iron lofts differ a lot between models and generations. In our records the 2017 TaylorMade M2 has a 28.5° 7-iron and the Titleist AP2 (712) a 35° 7-iron. With a similar strike, more loft at impact tends to launch higher, spin more and land more steeply. A loft chart can tell you that tendency. It cannot tell you how far either club will carry for you, because ball speed, strike and delivery decide that. Put two published charts side by side with the iron comparison tool, then check real carries before you change a set.

The trajectories come from this site's own model, the same one used in the ball flight laws guide. It treats the ball as a point mass with gravity, drag and Magnus lift. Its lift and drag curves follow the shape of published wind-tunnel results for spinning golf balls (Bearman and Harvey, 1976; Smits and Smith, 1994), and spin decays about 4% per second. Wind is uniform with height. The model leaves out temperature, altitude, humidity, ball design, Reynolds-number effects, bounce and roll, and all inputs are illustrative. Use it to understand how launch, spin and wind change a shot, not to predict yardages or choose equipment. Sources checked October 8, 2026.
