Exit velocity calculator
Enter an exit velocity and launch angle and get the projected carry distance, for a baseball or a softball. This is the exact ball-flight model that runs inside the SwingDino app: numerical integration with air drag and lift, not a lookup table.
Projected, not measured. Assumes solid contact and a typical trajectory, sea level, no wind.
Exit velocity to distance chart
Projected carry in feet for a baseball, by trajectory. Projections assume solid contact at sea level with no wind. Real results vary; that is the point of measuring your own.
| Exit velo | Line drive (15°) | Fly ball (25°) | High fly (35°) |
|---|---|---|---|
| 30 mph | 37 ft | 49 ft | 57 ft |
| 40 mph | 59 ft | 80 ft | 93 ft |
| 50 mph | 99 ft | 132 ft | 143 ft |
| 60 mph | 138 ft | 181 ft | 192 ft |
| 70 mph | 183 ft | 233 ft | 241 ft |
| 80 mph | 232 ft | 286 ft | 290 ft |
| 90 mph | 284 ft | 339 ft | 336 ft |
| 100 mph | 337 ft | 391 ft | 380 ft |
Calculator questions
How far does a ball go at a given exit velocity?
It depends on launch angle as much as speed. As rough projections for a baseball hit on a line-drive-to-fly-ball trajectory: 50 mph carries around 100 to 140 feet, 70 mph around 180 to 240, and 90 mph around 280 to 340. Use the calculator above for exact combinations.
What launch angle gives the most distance?
For most exit velocities the projected carry peaks in the high 20s to mid 30s of degrees. Below about 10 degrees the ball is a grounder or low liner and distance projections stop meaning much, which is why we flag them.
Is this calculator accurate?
It runs the same physics model our app uses: numerical ball-flight integration with drag and lift, validated against published trajectory data. But any distance from exit velo and launch angle is a projection. Real carry varies with wind, altitude, air temperature, and how flush the contact was.
How do I measure my exit velocity to use here?
SwingDino measures it free with just an iPhone set to the side of a tee: the camera tracks the ball off the bat and reads its speed, then deletes the video and keeps only the numbers.
Don't know your exit velocity?
SwingDino measures it free with the iPhone you already own. Set the phone to the side of the tee, take ten swings, and get your real number, plus the by-age context to make sense of it. Honest about how we measure.
