Pitching numbers by age at a glance
Parents ask about two numbers more than any others: how hard he should throw, and how many pitches he can throw in a day. This chart puts both side by side. The typical fastball range is the middle half of pitchers his age, and anything above it is above average. The daily max comes from MLB and USA Baseball's Pitch Smart guidelines, and Little League uses the same maximums through league age 16. Pitch Smart also sets 50 pitches for ages 7 and 8 and 120 for ages 19 to 22. How many days of rest he needs depends on the count, so the pitch count calculator works out the exact date. Compare him to himself, not to the kid on Instagram.
| Age | Typical fastball | Above average | Pitch Smart daily max |
|---|---|---|---|
| 9-10 | 40-50 mph | Above 50 mph | 75 pitches |
| 11-12 | 50-60 mph | Above 60 mph | 85 pitches |
| 13-14 | 60-70 mph | Above 70 mph | 95 pitches |
| 15-16 | 70-80 mph | Above 80 mph | 95 pitches |
| 17-18 | 75-85 mph | Above 85 mph | 105 pitches |
Pitch count and rest day tools
These two work as a pair. After a game, the pitch count calculator tells you how many days of rest he needs and the first date he can pitch again, under Pitch Smart or Little League rules. The printable sheet covers the whole week, every team, so you see his real total. That matters because each league only counts its own games, and his arm counts all of them. Rest days are full calendar days, the day he pitched doesn't count, and no pitcher should pitch three days in a row. Any arm pain means no pitching, whatever the count says. See a doctor if it hurts.
Velocity tools: speed by age and by distance
The velocity checker places his fastball against other pitchers his age, 9 through 18, as an estimated percentile. The pitch speed converter answers a different question: how fast a pitch from a 46 or 50 foot youth mound looks to the hitter compared to 60 feet 6 inches. A 60 mph fastball from 46 feet gives the hitter about as much time as a 79 mph fastball from the full distance. That's the hitter's reaction time, not a prediction of how hard he'll throw on the big field. Radar guns and phone apps can disagree by 3 to 4 mph on the same pitch, so watch his trend over a season, not one reading.
Pitching stats: ERA, WHIP and strike percentage
The ERA calculator turns his pitching line into ERA, WHIP, strikeouts and walks per nine, strike percentage, and pitches per inning. It reads innings the way a scorebook writes them, so 5.2 means five innings and two outs, not a decimal. Pick a 6-inning youth game, a 7-inning high school game, or the standard 9-inning scale, and compare pitchers on the same one. ERA moves slowly. Strike percentage and first-pitch strikes move faster, so they show progress sooner and tell you whether he's working ahead in the count.
Field dimensions, wristband signs and pitching terms
The field dimensions lookup shows the pitching distance, base paths, and mound height for each league and division. Most kids start on a 46/60 field, many move to 50/70 around 11 to 13, some leagues and events add a 54/80 step at 13 or 14, and high school plays at 60 feet 6 inches with 90-foot bases and a 10-inch mound. The wristband signs generator builds pitch-calling cards and the matching coach's sheet, with new numbers every time you shuffle. The glossary explains the words you hear from coaches, scouts, and radar readouts in plain English.
How to use the tools through a season
Before the season, get a velocity reading so you have a starting point, and take later readings under the same conditions. After every outing, write his pitches on the weekly sheet, for every team, and use the calculator to find the next day he can pitch. Every few games, run his line through the ERA calculator and look at strike percentage, not just runs. When he moves up a field, look up the new distance and mound height before the first practice. A few times a year, check velocity again and watch the trend. Little things now, big numbers later.
What the tools can't tell you
Numbers describe what happened: how hard, how many, how often. They can't show why. Velocity, strikes, and how hard each pitch is on his arm all come back to the delivery, with the legs, hips, trunk, and arm firing in order. When the legs, hips, and trunk do their share, the arm carries less of the load. That takes video to see. A coach-reviewed evaluation from one short phone video shows what his delivery does well and what to fix first. Compare him to himself, not to the kid on Instagram.
Where the numbers come from
Every tool shows its work. The pitch count tools follow the published charts in MLB and USA Baseball's Pitch Smart guidelines and Little League's regular-season rules. Field dimensions come from league rulebooks and event rules. The velocity ranges are compiled from published youth, travel, and high school velocity data. The ERA calculator and the speed converter print the formulas they use, with worked examples, and every tool page shows the date it was last updated. Rules can change from season to season, and local leagues, tournaments, and state high school associations can set their own, so check yours before a big decision.
Common questions
Are these pitching tools really free?
Yes. Every tool is free to use with no account and no email required. Names you type on the printable pitch count sheet stay on your device and only appear on the printed sheet.
Who are the tools for?
Mostly parents of youth pitchers, plus high school and college pitchers and the coaches who work with them. The pitch count tools follow MLB and USA Baseball's Pitch Smart guidelines and Little League's rules.
Do these tools work for high school and college pitchers?
Yes. The pitch count calculator and log follow Pitch Smart, which runs through age 22, and the ERA calculator works on 7-inning high school and 9-inning college scales. The velocity checker covers ages 9 through 18. The field dimensions run from Little League to the pros. One catch for high school: every state association sets its own pitch count rules for games, so check yours. Pitch Smart's numbers are a sound guide for everything else he throws.
What's the difference between a pitch count calculator and a pitch count log?
The calculator answers one outing: enter his age and pitches and get his rest days and the first date he can pitch again. The log tracks the whole week on one printed sheet, every game, bullpen, and practice for every team, with the rest rules for his age printed at the bottom. Use the calculator after a game and the log to keep the running total. Coaches can also print a tournament weekend sheet for the whole staff.
Do I need a radar gun to check my son's pitching speed?
Only for the velocity checker and the pitch speed converter, which need a speed reading. A handheld radar gun or a radar phone app is fine for tracking progress. Readings can differ by 3 to 4 mph on the same pitch, so measure under similar conditions a few times a year and watch the trend, not any single number. The pitch count, stats, field, wristband, and glossary tools need no equipment at all.
Do the pitch count tools follow Little League or Pitch Smart rules?
Both, and you pick the rulebook. Pitch Smart is MLB and USA Baseball's guideline for ages 7 through 22. Little League's regular-season rules use league age, his age on August 31, and stop at 16. The two share the same daily max and rest-day table through 16, and neither allows pitching three days in a row. Tournaments, local leagues, and state high school associations can set different rules, so check yours.
Can a tool tell me if his mechanics are good?
No. The tools work from numbers, and mechanics have to be seen. A coach-reviewed video evaluation shows what his delivery is doing well and what to fix first, free from one short phone video.
