Calculate perceived pitch velocity, like how fast 70 mph from 46 feet is at MLB distance, or pitch speed from distance and time for baseball or softball.
Pitching Velocity Formula
The following equation calculates average speed over a measured ball-flight interval.
- Where PV is the average speed over the timed interval (mph)
- D is the measured distance over the same release-to-arrival interval (ft)
- T is the time of the pitch (s)
Dividing distance in feet by time in seconds gives feet per second. Multiply by 3,600 / 5,280 = 15/22 to convert that average to mph. Measure distance between the same endpoints used to start and stop timing. If distance is horizontal displacement rather than the full path length, the result is the average horizontal speed component.
Average Pitching Velocity by Age
Pitching velocity benchmarks vary significantly across age groups. These ranges represent the average fastball velocity for each level, with elite pitchers typically falling at or above the top end.
| Age/Level | Mound Distance | Average Velocity (MPH) | Elite Velocity (MPH) |
|---|---|---|---|
| 9-10 (10U) | 35-46 ft | 40-50 | 55+ |
| 11-12 (Little League) | 46 ft | 50-60 | 65-70 |
| 13-14 (Middle School) | 50-54 ft | 60-70 | 75+ |
| 15-16 (JV/Varsity) | 60.5 ft | 70-80 | 82-85 |
| 17-18 (Varsity) | 60.5 ft | 78-85 | 88-92 |
| College (D1) | 60.5 ft | 88-92 | 94-97 |
| MLB | 60.5 ft | 93-94 | 98-105+ |
For a constant-speed illustration over the full listed distances, 60 mph over 46 ft takes about 0.523 seconds and 94 mph over 60.5 ft takes about 0.439 seconds. These are model flight times, not measured release-to-plate times or complete reaction windows. For an actual timed pitch, use its measured flight distance and interval-average speed.
Pitching Mound Distance by League
Different leagues and age groups use different rubber-to-plate distances. The ball is released closer to the plate, so the actual release-to-arrival distance differs. Use the Time to the plate and Perceived (equivalent) velocity modes with consistent distance endpoints to compare flight-time arithmetic.
| League/Level | Age Group | Mound Distance (ft) | Basepath (ft) |
|---|---|---|---|
| T-Ball / Coach Pitch | 4-7 | 35-38 | 50 |
| Little League (Minors) | 7-11 | 46 | 60 |
| Little League (Majors) | 10-12 | 46 | 60 |
| PONY Bronco / Cal Ripken | 11-12 | 50 | 70 |
| PONY Pony / Babe Ruth | 13-14 | 54 | 80 |
| High School / College / MLB | 15+ | 60.5 (60 ft 6 in) | 90 |
| Softball (Fastpitch) | 14+ | 43 | 60 |
The 60-foot-6-inch distance used from high school through MLB was established in 1893. Before that, pitchers threw from 50 feet, but the offensive explosion at that distance prompted the rule change. This distance has remained unchanged for over 130 years.
Average MLB Pitch Velocity by Pitch Type
Pitching velocity is not uniform across pitch types. Each pitch serves a different purpose in a pitcher’s arsenal, and speed differentials are what make them effective. Below are average MLB velocities by pitch type as of the 2025 season.
| Pitch Type | Avg. MLB Velocity (MPH) | Typical Speed Differential vs. Fastball |
|---|---|---|
| 4-Seam Fastball | 94.0 | Baseline |
| Sinker (2-Seam) | 92.5 | 1-3 mph slower |
| Cutter | 88-95 | 2-6 mph slower (varies widely) |
| Changeup | 85.9 | 8-10 mph slower |
| Slider | 84-88 | 6-12 mph slower |
| Curveball | 80.5 | 12-16 mph slower |
| Splitter | 85-88 | 6-10 mph slower |
The average MLB four-seam fastball has increased from 89.0 mph in 2002 to 94.0 mph in 2025, a 5.6% increase over 23 years. Meanwhile, four-seam usage has dropped from 64.4% to 47.9% over that same period, as pitchers increasingly rely on sliders (now 22.4% usage, up from 12.1% in 2002) and other breaking pitches. This shift reflects a broader strategic evolution toward tunneling and speed differential rather than pure velocity.
Biomechanics of Pitching Velocity
Pitching velocity is produced through a kinetic chain that transfers energy from the ground, through the legs and hips, into the trunk, through the shoulder and arm, and out through the hand. Research has identified several measurable factors that correlate with higher velocity.
Stride Length: Studies of collegiate pitchers show that stride length is positively correlated with ball velocity. The target is roughly 85% of the pitcher’s height, with the lead foot landing in a slightly closed position. Hip abduction flexibility in the stride leg has a significant positive correlation with achievable stride length.
Hip-to-Shoulder Separation: High-velocity pitchers open their hips earlier and at a faster angular rate than low-velocity pitchers. The pelvis reaches rotational velocities of 400 to 700 degrees per second during the delivery. This creates a stretch across the core that stores elastic energy before the trunk fires. Greater separation between hip and shoulder rotation produces more rotational force.
Shoulder Internal Rotation: At peak, shoulder internal rotation reaches 7,000 to 9,000 degrees per second, making it the fastest measured human movement. This is the final link in the kinetic chain before ball release.
Ground Reaction Forces: Research indicates that ground reaction forces can explain up to 61% of the variance in throwing velocity. Pitchers who generate more force into the rubber and through the stride leg into landing tend to throw harder. This is why lower body strength training (deadlifts, single-leg exercises, plyometrics) is a core part of modern velocity development programs.
Flight Time and Equivalent-Distance Speed
In a constant-speed illustration, 70 mph over 46 ft gives a flight time of about 0.448 seconds, while 94 mph over 60.5 ft gives about 0.439 seconds. Equal modeled flight time does not establish equal difficulty or a complete batter reaction window. The comparison below uses the listed distances as arithmetic references, without modeling release extension or changing speed.
| Scenario | Distance (ft) | Speed (MPH) | Modeled Flight Time (s) | Equivalent Speed at 60.5 ft (MPH) |
|---|---|---|---|---|
| Youth 46 ft, 55 mph | 46 | 55 | 0.570 | 72.3 |
| Youth 46 ft, 65 mph | 46 | 65 | 0.483 | 85.5 |
| Youth 50 ft, 70 mph | 50 | 70 | 0.487 | 84.7 |
| HS 60.5 ft, 85 mph | 60.5 | 85 | 0.485 | 85.0 |
| College 60.5 ft, 92 mph | 60.5 | 92 | 0.448 | 92.0 |
| 60.5 ft, 100 mph example | 60.5 | 100 | 0.4125 | 100.0 |
| Softball 43 ft, 65 mph | 43 | 65 | 0.451 | 91.5 |
Under this model, an average 65 mph over 43 ft and an average 91.5 mph over 60.5 ft have approximately the same flight time. The listed nominal distances are comparison references, not measured release distances. This equivalent-distance speed is not MLB Statcast Perceived Velocity and does not establish an identical batter reaction window.
Fastest Pitches Ever Recorded
The Statcast era (2015-present) provides precise tracking data for every MLB pitch. Below are the top recorded pitch speeds in MLB history.
| Pitcher | Speed (MPH) | Date |
|---|---|---|
| Aroldis Chapman | 105.8 | Sept. 24, 2010 |
| Aroldis Chapman | 105.7 | July 18, 2016 |
| Ben Joyce | 105.5 | Sept. 3, 2024 |
| Aroldis Chapman | 105.4 | July 18, 2016 |
| Aroldis Chapman | 105.2 | July 22, 2016 |
At an assumed constant 105.8 mph, a 60.5 ft reference distance gives about 0.390 seconds of modeled flight time. The actual release point is closer than the pitching rubber, and the ball changes speed in flight. This calculator does not model a batter’s recognition, decision or swing timing.
How Pitching Velocity Is Measured
There are several methods used to measure pitch speed, each with different accuracy and accessibility.
Radar Gun: The traditional tool, used by scouts since the 1970s. Measures the peak speed of the ball, typically captured near the pitcher’s release point. Consumer-grade units (Pocket Radar, Stalker) cost $100-$400 and are accurate within 0.5-1 mph. Professional units used in stadiums are accurate within 0.1 mph.
Statcast (Hawk-Eye): MLB’s tracking data report pitch speed at release. That quantity differs from average speed over a measured flight interval. The stopwatch calculation does not reconstruct release speed or model the ball’s changing speed.
Stopwatch Method: Time the same ball-flight interval whose actual distance is entered. Average speed in mph = distance in feet / time in seconds × 15/22. Human timing error can be large; this estimate is an interval average rather than radar release speed. Video frames can help define the interval, but endpoint, frame-rate and distance errors still matter.
Video Analysis (Dartfish, Kinovea): Video tools let you mark release and arrival frames. At 240 fps, one frame spans 1/240 second, about 0.00417 seconds. Choosing either endpoint can affect the measured interval; speed accuracy depends on flight time, endpoint selection and distance accuracy, so frame rate alone does not guarantee a fixed mph error.
