Softball Pitch Speed Calculator

Calculate the speed of a softball pitch by measuring the distance and time it takes to reach home plate.

Standard fastpitch distance is 43 feet from pitcher's rubber to home plate
Time from pitcher's release to when the ball reaches home plate

How to Use This Calculator

  1. Measure the distance from the pitcher's release point to home plate (standard is 43 feet for fastpitch)
  2. Time the pitch from release to when it reaches home plate using a stopwatch
  3. Select the pitch type and age group for comparison data
  4. Click Calculate to see the pitch speed in both mph and km/h

Formula Used

Speed (mph) = Distance (feet) / Time (seconds) × 0.681818

Where:

  • Distance = The distance from pitcher's release point to home plate in feet
  • Time = The time it takes for the ball to travel from release to home plate in seconds
  • 0.681818 = Conversion factor from feet per second to miles per hour

Example Calculation

Real-World Scenario:

A high school pitcher throws a fastball that takes 0.5 seconds to reach home plate from the standard 43-foot distance.

Given:

  • Distance = 43 feet
  • Time = 0.5 seconds

Calculation:

Speed (mph) = 43 feet / 0.5 seconds × 0.681818 = 58.64 mph

Result: The pitch speed is 58.64 mph (94.34 km/h), which is above average for a high school pitcher.

Why This Calculation Matters

Practical Applications

  • Tracking pitcher development over time
  • Comparing performance against age-group standards
  • Identifying effective pitch speed differentials

Key Benefits

  • Helps pitchers set realistic goals
  • Allows coaches to assess effectiveness
  • Provides objective feedback for training

Common Mistakes & Tips

Many people measure from the pitching rubber to home plate (43 feet), but the actual release point is typically 2-5 feet in front of the rubber. For more accurate results, measure from the pitcher's actual release point to home plate.

Starting the stopwatch too early or too late can significantly affect your calculations. Start timing exactly when the pitcher releases the ball, not when they begin their windup. Stop timing when the ball reaches home plate, not when the catcher catches it.

Frequently Asked Questions

Average fastball speeds by age group: 10U (35-40 mph), 12U (40-45 mph), 14U (45-50 mph), 16U (50-55 mph), 18U (55-60 mph), College (60-65 mph), Professional (65-70+ mph). These are general ranges and individual pitchers may vary.

Manual timing with a stopwatch can be reasonably accurate (within 2-3 mph) if done consistently by an experienced timer. Radar guns provide more precise measurements but are expensive. For most training purposes, manual timing is sufficient to track progress and identify improvements.

An effective changeup is typically 8-12 mph slower than a pitcher's fastball. This speed differential creates timing issues for batters. Less than 8 mph difference may not be effective, while more than 12 mph can make the changeup too easy to recognize.

Accuracy Notice

Manual timing methods have inherent limitations and may produce results that differ from radar guns or other electronic measurement devices. For most training purposes, this calculator provides sufficient accuracy to track progress and identify areas for improvement.
