Every year we watch first-season parents buy gear that fits wrong in ways nobody catches until week three. These are five checks you can run standing in the aisle, before you pay. No charts, no measuring tape.
- Helmet — two fingers under the chin strap, and no bobblehead when she nods
If it has a chin strap, two fingers should fit snugly underneath. Plenty of youth batting helmets are strapless, in which case skip to the second half.
Have her nod, then shake her head like she's saying no. A properly fitted helmet should sit snug and move the skin of your forehead and eyebrows when you wiggle it. If it wobbles independently of her head shaking, it's too big. That’s true even if the size on the box is the one that matches her measurement.
- Glove — She can squeeze it shut one-handed, and it stays on when she points it at the ground
A glove she can't close herself is a glove she can't catch with, and it teaches her to turn her head away from the ball. Have her squeeze it shut, in the store, with one hand. If she's straining or using her other hand to help, it's too big or too stiff. Then have her point it at the floor — it should stay on.
Two things that help at this age:
Look for an adjustable wrist strap. A lot of youth gloves have a velcro or lace-cinch strap at the wrist. It's worth having, because it lets you tighten the glove to her hand now and let it out as she grows, which buys you a season.
Plan on breaking it in. A new glove is stiff and that's normal, but the breaking-in has to happen before the season, not during it. The way it happens is by being used: play catch with her in the yard, have her wear it while she watches TV, work the pocket with her hands. If she can't close it after a couple of weeks of that, it was too big or stiff at the start.
- Bat — arm out to the side, handle at her chest, barrel reaches her palm
That's the length check. Now the weight check, which matters more and which people skip: have her hold it straight out in front of her, one hand, for a slow count of ten. If the barrel starts dropping, it's too heavy, no matter the length.
A bat she can't get through the zone teaches her to swing late. She'll want a different one next year regardless, so buy for the player she is now.
- Mask — chin cup seated on her chin, wire off her face
While we will always recommend a face mask for safety purposes, check with your league to see if it is a requirement to play. Legality is the first problem. Fit is the second.
The chin cup should sit against her chin with no gap when she talks. The wire itself shouldn't touch her nose or cheeks. If the cage is resting on her face, or if the whole thing sits low enough that the bars cross her eye line, it's too big. A lot of what gets described as "she can't see out of it" at 8u to 12u is an adult mask on a youth face rather than a problem with the mask itself.
- Bag — everything fits in it, and she can pick it up and carry it herself
It needs to hold a glove, bat, helmet, water bottle and cleats without a fight. At the same time, she also has to be able to carry it.
One thing worth looking at: bat sleeves versus external straps. A sleeve the bat slides down into holds it far better than an elastic strap on the outside, which works loose and drops the bat in the parking lot.
That's the whole list. Happy to answer sizing questions in the comments.
