Baseball bat size charts by age
Age → length / drop tables, height charts, and kitchen fit tests — built to answer the searches parents actually type. Last content review: October 23, 2026.
Parent disclaimer: Charts are starting points from common manufacturer age/height tables — not a perfect fit for every kid. Confirm stamp and drop rules with your league and each tournament. We don’t give medical or swing-coach advice.

Aligned with common Rawlings / DeMarini / Louisville published bands — always verify with fit tests.
Kitchen fit tests (better than the chart alone)
- Hip test (length): Stand the bat upright beside the player, barrel on the floor. The knob should reach roughly mid-hip. Up at the waist is usually too long; down at the thigh is usually too short.
- Arm / hold test (weight): Have them hold the bat straight out one-handed, parallel to the ground, for about 10 seconds. If the barrel sinks, the bat is too heavy — stay at the same length and go lighter on the drop, or shorten an inch.
- Chest / fingertip check: Knob at center of the chest, bat pointing out along an outstretched arm. Fingertips should reach the end cap comfortably.
- Between sizes? Take the shorter / lighter option. A bat they can control beats one they “grow into.”
