How do I grip a basketball better than my brother who has bigger hands?

I am just wondering how I grip a basketball better than him. My brother is 18 and I'm 14. He has slightly bigger hands than me and struggles gripping a basketball yet I can pretty easily.|||Palming the ball (or gripping) is all based on your finger strength. You can have stronger fingers than your brother and or your finger width is bigger, indicating more strength.
