Works great! I used this for the first time and not once did I feel any bat sting. With that confidence I am now crushing the ball with out thinking about any sting.

Size chart

Find the right ThumbPRO® baseball thumb guard size based on weight, hand size, batting glove thickness, and fit preference. With three sizes for players ages 6+, ThumbPRO® helps every hitter achieve a secure fit for comfort, confidence, and performance.

How ThumbPRO® Sizing Works

ThumbPRO® sizing starts with weight because it provides the most reliable fit for most players. Hand size, batting glove thickness, and fit preference also matter, so use the chart as your starting point and fine-tune from there

SizePlayer weight
SmallUnder 115 lbs
Medium115–195 lbs
Large195+ lbs

Fit Tips for Baseball and Softball Players

For a performance fit: If you are between sizes, many competitive players prefer sizing down for a more locked-in feel.

For a comfort fit: If you want more room or dislike tight gear, consider sizing up.

If you wear batting gloves: Think about whether your ThumbPRO® will be worn over your glove and whether your gloves are thin or padded.

For younger players: Start with weight rather than age. Younger players may wear Small, Medium, or Large depending on their build, hand size, and batting glove thickness.

Optional: How to Measure Your Thumb

If you want an extra fit check, wrap a string or ribbon around your thumb halfway between the first and second knuckles. Compare the fit with the size guide, but remember: weight is usually the best starting point.

Diagram: Small 2¼″ circumference, approximately 115 lbs and under; Medium 2½″, approximately 115–195 lbs; Large 2¾″, approximately 195 lbs and up. Measure with your batting gloves on, between the base and first knuckles of your thumb.

ThumbPRO® Sizing FAQs

What size ThumbPRO® should I buy?

Start with the sizing chart, then consider hand size, batting glove thickness, and fit preference. Small generally fits players under 115 lbs, Medium generally fits players from 115–195 lbs, and Large generally fits players 195+ lbs.

How do I choose the right baseball thumb guard size for my child?

Start with your player’s weight rather than age alone. Children ages 6 and up may wear Small, Medium, or Large depending on their weight, hand size, batting glove thickness, and fit preference. Use the ThumbPRO® sizing chart as your starting point.

Should ThumbPRO® feel tight?

ThumbPRO® should feel snug and secure, but not painfully tight. A secure fit helps the thumb guard stay in place during swings.

What if I am between sizes?

If you are between sizes, size down for a tighter performance fit or size up for more comfort.

Can I wear ThumbPRO® with batting gloves?

Yes. If you wear thicker batting gloves or plan to wear ThumbPRO® over your glove, consider that when choosing your size.

How long does it take to get used to wearing a thumb guard?

Most players adjust quickly, but first-time users should give ThumbPRO® a few at-bats to feel natural. Younger players may need a little more time as they adjust to something new. Parents often tell us that once their child gets used to ThumbPRO®, they feel more confident at the plate, no longer fear the sting, and do not want to hit without it.
