What it does

Tee-ball shrinks baseball to starter size: 50 ft bases, coach pitched balls, and soft cores that forgive small hands. Everything else mirrors the big diamond in miniature.

The tool above takes the field count in feet or meters. It returns bases, pitching setup, and diamond count.

The default single field reads 50 ft bases with coach pitch. The metric mirror reads 15.2 m, and two fields line 2 diamonds.

League field specifications publish the 50 ft tee-ball option with coach pitch play. Playing rules hubs repeat the same starter setup with safety balls.

Line small, play big: short bases keep innings moving while soft balls keep faces safe. Majors ball at 60 ft with 40 ft pitching waits two divisions up.

  2. Type the field count.
  3. Read bases first.
  4. Read pitching beside it.

  6. Set tees and soft balls.

Little League field specifications allow the 50 ft diamond option for tee-ball divisions with coach pitch play. League playing rules hubs carry the same tee-ball setup with soft core balls. Metric mirrors multiply feet by 0.3048.
