Exit Velocity Guide

Average exit velocity by age

Published July 8, 2026 • 6 minute read

Exit velocity climbs fast through the growth years, then flattens as hitters reach their strength ceiling. Knowing the typical number for an age keeps expectations honest — a 10-year-old at 48 mph and a college hitter at 48 mph are two very different stories.

Average exit velocity by age chart

These are approximate averages for solid contact — a clean barrel hit off a tee or a machine, not a mishit and not a once-a-session peak. Individual players vary widely, and early or late physical maturity moves a hitter up or down the chart more than age alone.

Age	Typical average EV	Strong for age
8	38–42 mph	48 mph
9	42–46 mph	52 mph
10	46–50 mph	57 mph
11	50–55 mph	62 mph
12	54–60 mph	66 mph
13	58–65 mph	72 mph
14	63–72 mph	80 mph
15	68–78 mph	86 mph
16	73–84 mph	91 mph
17	78–88 mph	95 mph
18	82–92 mph	98 mph
College	88–98 mph	103 mph
Pro / MLB (in-game avg)	88–90 mph	115+ mph peak

Want a real number for one player instead of a range? The exit velocity calculator compares an exit velocity to the level benchmark and estimates how far that contact carries.

Need a team-level comparison instead of an exact age? The exit velocity chart by level groups youth, middle school, high school, college, and pro benchmarks without duplicating this age-by-age table.

Why the number jumps most from 12 to 16

The steepest gains show up in the growth-spurt window. Between roughly 12 and 16, hitters add height, lever length, and fast-twitch strength — all of which raise bat speed, and bat speed is the biggest driver of exit velocity. A player can gain 15–20 mph of exit velocity in two years during this stretch without changing anything about their swing.

That is also why comparing a young hitter to an older one is misleading. Two players with identical mechanics can be 20 mph apart purely because one hit their growth spurt first.

How to read a young hitter's number

Use the average across a full session, not the single hardest hit. One perfect swing on a grooved pitch is not the baseline.

Log the launch angle next to it. A low exit velocity paired with a ground-ball angle is a different problem than one paired with a good angle.

Retest every 4–6 weeks with the same setup — same tee height or machine speed — so the comparison actually means something.

Expect noise. Fatigue, pitch location, and bat weight all move the number day to day.

Exit velocity by age FAQ

What is the average exit velocity for a 12 year old?

A 12U hitter making solid contact typically produces around 50 to 60 mph, with stronger players reaching the mid 60s. Use the session average, not one peak reading.

What is a good exit velocity for a high school player?

High school hitters generally range from about 68 to 92 mph. Varsity players headed to college often sit in the mid 80s to low 90s, and anything above 90 mph is a strong, recruitable number.

What is the average MLB exit velocity?

Average in-game MLB exit velocity is roughly 88 to 90 mph across all batted balls, with elite hitters peaking above 115 mph on their hardest contact.
