Finding Your Perfect ThumbPRO® Size

ThumbPRO® sizing is based on weight ranges, but every hand is a little different. While you can measure your thumb using a string or ribbon around the thumb halfway between the first and second knuckles (as shown in the image above), we've found that weight is generally the most reliable way to determine your ideal size.

He shares tips on how to choose the correct ThumbPRO® size:

Weight-Based Size Guide

Small: Under 115 lbs (youth, age 7+)
Medium: 115–200 lbs (most teens/adults)
Large: 200+ lbs (larger adults)

Your ThumbPRO® should fit snug, not too tight—because the right fit means maximum protection and confidence at the plate. If you're in between sizes, performance players often size down for a locked-in fit, while others size up for comfort. If you play with batting gloves, consider how the ThumbPRO® will fit over them.
