For young or smaller than average players we would recommend the 7A drum sticks. These are quite a lot thinner than the 5A and are great for smaller hands.
For average size players we would recommend the 5A drum sticks. These are a medium weight, medium thickness stick and a good place to start off.
For big players or people with larger hands, we would recommend the 5B drum sticks. These are slightly larger in diameter than the 5A and are also slightly heavier.
