How to measure it correctly
Measured barefoot against a wall, heels together, first thing in the morning for consistency.
Reading the numbers the right way
Averages describe a population, not a ceiling. Two players at the same age can be a full year apart in physical maturity, so treat these numbers as a starting reference point and focus on your own rate of improvement.
How to improve
Sleep is the growth lever you control
Most growth hormone release happens during deep sleep. Nine to ten hours per night through the growth years does more for height than any supplement.
Fuel the growth spurt
Underfeeding during a growth spurt costs strength, not height. Prioritize protein at every meal plus enough total calories to support training.
Train what height cannot give you
Bat speed, sprint speed, and arm strength are all trainable. Undersized players who move well keep getting recruited every year.

Frequently asked questions
What is the average height for a 12-year-old baseball player?+
Roughly 59-60 inches, or about 4 feet 11 inches. The 90th percentile at that age is close to 63.5 inches.
Is being short a problem in baseball?+
No. Height helps pitchers with leverage, but there is no height requirement for hitting, fielding, or speed, and short players succeed at every level.
When do baseball players stop growing?+
Most male athletes finish growing between 16 and 18, though some add another inch into their late teens.
