how long of a board do i need to get for my 8 year old he is 52 inchs tall
Trying to figure out the size relies on height yes, but more importantly, weight. For the remaining size of 142cm, he is 10cm shorter than the board, that scenario should be reversed if anything and he should be weighing in at 110-120 lbs. The Label is a great board, perhaps the 2010 version might interest you.
Follow the weight/size chart.
