Glove & mitt sizing for 12U

Biggest destination year for many teams — position-specific gloves start to matter as much as bat stamps. Reviewed October 23, 2026.

Parent disclaimer: Sizing charts are starting points. Brands and hand shapes differ — try gloves on when you can, and confirm any mitt rules with your league or coach. We don’t give medical advice.

1. Age snapshot

At 12U, stronger arms and bigger diamonds reward the right pattern. Intermediate / early-teen models show up on shelves. Match the glove to the position they play most — then confirm it still closes cleanly.

Typical fielder range: Fielder gloves commonly 11–12″. Many 12U travel infielders sit near 11.25–11.75″; outfielders closer to 12″.

How to measure (hand & glove)

Charts below are parent buying ranges — not medical or coaching prescriptions. Brands vary; try on when you can.

2. Sizing by position

First base often uses a dedicated mitt (larger, shallow scoop) once kids play there regularly — usually introduced more seriously around 11U–14U.

3. Quick buying checklist

  1. Know the primary position (or buy a versatile middle size if they float).
  2. Match the inch range above — then prioritize a glove they can close.
  3. Soft / easy-break-in leather beats a stiff “pro” model they can’t squeeze.
  4. Confirm throw-hand (RHT vs LHT) before checkout.
  5. Plan break-in time before the first tournament weekend.
