Choosing a baseball jersey is not only about comfort; its size will also affect the performance of a player, the overall appearance of the team, and their confidence while playing on the field. At RBZ Apparels, we develop custom uniforms for USA-based teams and ensure they will fit youth and adults perfectly with high-quality craftsmanship. This detailed guide contains everything that a coach, team manager, or player needs to know to choose the proper size chart of their baseball jersey. It includes measurement charts, measurement tips, and professional advice about sizing your jersey properly every time.
Why Proper Baseball Jersey Sizing Matters
Baseball uniforms worn correctly can provide the following benefits:
- Enhanced performance – Baseball uniforms provide optimal freedom of movement to allow players to hit, pitch, and field.
- Professional appearance – Clean, uniform look for your team
- Comfort during long games – Breathable fit reduces fatigue
- Durability – Proper fit prevents fabric stress and tearing
Oversized or overly tight-fitting jerseys can negatively affect player performance and the team’s overall presentation.
How to Measure for a Baseball Jersey (Step-by-Step)
To pick the right size jersey, the players should first be measured properly.
1. Chest Measurement
To get a chest measurement, measure around the biggest part of the players’ chest while keeping the tape level.
2. Waist Measurement
To get a sleeve length measurement, measure from the shoulder seam to the end of the sleeve.
3. Jersey Length
Start measuring from the top of the shoulder downward to reach your desired length.
4. Sleeve Length (Optional)
Measure from the shoulder seam for the sleeve length to the end of the sleeve.
Pro Tip (RBZ Apparels): When measuring, use only a light-clothing shirt so you will receive accurate measurements.

Common Sizing Mistakes to Avoid
Many teams face sizing issues due to these common errors:
- Guessing sizes without measurements
- Ordering all players in the same size
