BAT: The ideal length for a bat is the inside measurement of the batsman’s trousers. Children over the age of seven fare best with bats that weigh no more than a kilogram.
TIP: Lift the bat in the non-dominant hand (i.e.: The left hand if right-handed), and to hold it out horizontally with the shoulder for one minute. If he can do this without strain or difficulty, the weight is correct.
